Quality and service were excellent. Installers were very friendly, explained the process, gave updates along the way, and cleaned up well.


The Rockweiler team was fantastic. Very friendly, clearly knowledgeable, and showed great care for our property while doing the work. Would highly recommend them!


Awesome experience with this company from start to finish! Aaron and Louie did an excellent job today with improving our home insulation in our attic and basement – got both done in one day! Very professional, kind, and explained everything clearly. Also, they cleaned up so well, I couldn’t tell they’d even been here!


Rockweiler insulated our attic. We received multiple bids. Theirs wasn’t the lowest but it was reasonable and they came well recommended. Before blowing in the insulation, all openings to the attic including for air conditioning outlets and lights were fully insulated. The vents were all properly protected with new coverings. The employees that were sent – Aaron and Louie – were a pleasure to work with. We have had our share of lousy contractors so it was a delight to work with people who were conscientious about getting their work done properly and proud of it. I recommend them highly.


Aaron and Louie did a fantastic job. Very friendly and knowledgeable. We are very happy with the work they completed.


Excellent company to handle your insulation needs! Brian was very professional and made an appointment to come the following Monday to give an estimate. His crew was there a couple [of] days later and handled the job in a very timely fashion. I would highly recommend Rockweiler for any insulation needs. Thank you for your excellent service with my project!


Very polite and courteous technicians! Kept the house very clean throughout the re-insulating process.


Rockweiler improved the insulation in our attic. The crew was thorough, efficient, professional, and personable. They accessed our attic in just one of three entries reducing the chances of insulation material spreading throughout our house. They also cleaned up well when the job was done. We would highly recommend Rockweiler.


The Rockweiler crew, Aaron and Luis, did a stellar job of upgrading our attic insulation. They were professional, efficient, warm, and very considerate. Throughout the process, Aaron showed us photos of issues that needed to be resolved and explained the work they were doing. Their work was done to the highest standard. We were thrilled that this Verona-based firm was willing to come to our house in Milton to help us out. Thank you SO much for a job that “exceeded our expectations.”


Aaron and Louie did a wonderful job efficiently and thoroughly. They cleaned up any debris that had been left, plus cleaned off my stoop! The same evening after they finished I realized that my house was much quieter. I wasn’t hearing squirrels running over the roof like I usually did. Great job by great guys!


We decided that we wanted to update the attic installation of our 18 year old home because we were experiencing issues with condensation at the top of a couple wall in the winter. We looked at the attic installation and found that it had settled and was blown away from the top of the wall in a few spots.

We contacted Rockweiler to get an estimate, and the estimator that came out was prompt and did a nice job of explaining what he found and explaining what some options were available to us. He sent us an estimate for three different upgrade options and let us decide what we wanted to do.

After we decided what we wanted to do, we scheduled the upgrades. Rockweiler’s small crew was great. Friendly, knowledgeable and capable. They got to work and it only took them a few hours to seal up air leaks throughout the entire attic before blowing in the additional insulation that we requested.

It has been two warm summer months since we had the attic sealed and increased the insulation from whatever R-value it was after the years of settling to an R-value of 60 and the benefit was immediately noticeable. The house is much cooler and quieter now than it was before. There have been several days where in the past, we would have had to use the air conditioning, but now we just closed the windows in the heat of the day and opened up when the temperature dropped in the evening. And on the sustained hot days, the AC runs much less. We hadn’t expected to feel a difference in the summer, we did these improvements for the heating season. I am looking forward to seeing how the house will feel in the winter and I have no doubt that we will see a noticeable drop in our heating costs.

The Rockweiler team was also great with informing us about available rebates and tax credits to help offset costs of the upgrades.

Great experience.


“Rockweiler Insulation Inc. installers were on time, informative, friendly, and cleaned up the area well after the project was finished. We have definitely noticed the difference, that it keeps the temperature in the house more consistent.”


“Rockweiler added insulation in the attic and buttoned up around the lights, bath fan, etc. They also foamed the basement rim joist and plugged any other open air escape routes! The team I had was so pleasant and informative. I would highly recommend!”


“Rockweiler installed additional insulation in our home. The gentlemen that came to our home were extremely professional, friendly, and courteous. I greatly appreciated how organized and neat they were and how they cleaned up when finished. It was like they were never here.”


“We ended up not using their services, but I would go to them in a heartbeat with any future needs… when they came they looked at everything much more thoroughly than other companies had done. They told us that we were missing critical insulation, and while they offered to do it and provided us with an estimate, Pat pointed out that since our home is EnergyStar certified, it should be something that should have been done in the first place by our home builder. He recommended that before we used Rockweiler’s services, we should contact the homebuilder first to see if they would address the problem. We ultimately were able to have the whole project taken care of by the homebuilder, but that would have never happened without the honest recommendations of Pat and the team at Rockweiler.”


“The Rockweiler men spend a good deal of time installing chutes, foaming ceiling holes, fixing the bathroom ventilation tubing, installing foam board over the kitchen and bathrooms, and fixing anything else that was allowing warm moist air to move into our attic. They then blew in a foot of insulation. Before they started they covered steps and hallway with drop clothes [and] then vacuumed up pieces of loose insulation. I am happy and impressed with the work done.”


“10 out of 10. We hired this company to apply closed cell foam in our basement around the basement [box] sill. They [did] this accurately, professionally [and] in a reasonable [time]. They cleaned up after themselves. They covered all around the sill and spend a little extra time and materials to seal around old window sills… Great job!”


“Pat is knowledgeable, friendly, and professional. Our house is so much more comfortable in winter and summer since they added more insulation to the attic.”


“They put insulation in my attic. Fantastic job! The initial estimate was thorough and they gave me options so I could figure out what worked in my budget. The installers were on-time, polite, [and] fast. They explained to me each step they did. I compared several companies and I’m glad I chose Rockweiler. The price was lower than some other quotes, the work was excellent and I’ve also noticed a reduction in my electricity bill. Highly recommend!”


“Rockweiler reinsulated our attic areas. They did excellent professional work. There were several unexpected extra situations which they remedied with no additional charges. We would recommend them without any hesitation.”


“Had attic insulation and [attic] vents installed today. They helped me complete the energy rebate form and did a great job. Hoping it helps with winter gas bills and summer A/C. These guys were great! They entered the attic through my garage and cleaned and swept the entire area when finished. Honestly, it was cleaner when they left. Great service! Made me feel valued as a customer.”


“I would highly recommend this company, Pat gave me a fair price {and} was very nice to talk to and knowledgeable. The guys that did the install were very polite, went right to work, and got it right – also cleaned up well! They insulated both my three-car garage and the ceiling above my garage.”


“Had attic insulation work done this past week. The crew was on time, laid tarps to protect my flooring. They explained their process prior to starting the project and vacuumed afterwards, leaving my house as they found it coming in. Very professional, highly recommend them.” 


“The crew who installed the attic insulation was phenomenal. They kept me informed, were timely, and showed wonderful courtesy to the senior residents who live in the apartment building. It was clear they knew their jobs and materials. They also took time to report what they saw in the attic that needed attention. We are confident that the insulation work will be noticeable quickly this November and into the winter months, and especially so with our elevator which always seemed to pick up a cold draft from the attic. The draft disappeared, finally! Rockweiler performed exceptionally well.”


“Rockweiler was super responsive both for the estimate and the installation. Insulation was completed on time – very clean, thorough and professional.”


Aaron and Louie did a great job!… They are very dedicated to their work and Rockweiler Insulation Inc.


“The team at Rockweiler was stellar throughout the insulation process. We had them re-insulate our attic after we had vermiculite removed. Pat was very knowledgeable and shared a lot of information with us about different options and the process. Karen and the office staff were responsive and helped with coordinating scheduling. The team that performed the work was professional, courteous, and respected safety measures. And left the house clean! I also appreciated Pat and the team’s help in going above and beyond in helping with energy rebates, and talking us through that process. The only drawback is they book out fast – call them now and schedule your work!” 


“Work was done very efficiently by friendly and considerate professionals. Clean up after the work even better than I expected. I would highly recommend Rockweiler Insulation.”


“Aaron and Louie did a great job installing another layer of insulation in our attic. Our blown-in cellulose settled after 22 years and these gentlemen from Rockweiler brought us back up to the recommended R-value. It’s the third insulation job Rockweiler has done for us, as they are reliable and just do the job right.”


“I had Rockweiler out to my 80+ year old house. They insulated in the basement and the attic spaces. It was truly an amazing transformation. I could immediately feel the difference in my house, and I have noticed that my furnace rarely kicks in. I cannot wait to see the difference in my heating bills. The staff was so incredibly friendly and CLEAN! I highly recommend this company and have to anyone that listens!”


“I want to absolutely tell you how awesome the guys are doing on my insulation job! I know my attic is a challenge, but they are completing the work with attention to detail and smiles on their faces!”


“Had a phenomenal experience with the Rockweiler team. Pat did a wonderful job explaining our needs, benefits and cost versus value. The guys who then came to button-up our attic were professional, polite, friendly and considerate of our home. We could tell they have passion for doing a quality job. I recommend Rockweiler and will confidently refer them to others!”


“From the original request for an estimate to the service of installing, we were very pleased with Rockweiler. We received more than six quotes and went with Rockweiler because they were honest with us and didn’t try to oversell us. We first reached out to them in 2016. They asked us if we were planning to have any work done inside the house, and when we shared that we would be redoing the kitchen, they told us that we would want to wait to get the insulation. None of the other folks told us that. Had they not shared that with us, all the work we would have done would have needed to be re-done after the kitchen work. Additionally, when we asked them their thoughts on removing old insulation before putting down the new, they were honest and said in most cases it just wasn’t necessary. There were other companies that quoted us this service and it double the cost of insulation. The staff in the office were also always very helpful and provided us with resources and information we found to be helpful. Highly recommend Rockweiler!”


“We recently had insulation added to R60 in our attic by Rockweiler. They also performed advanced air sealing and installed ventilation baffles in every possible area. My hope was to have a contractor who could check all the boxes that met my expectations. On time – check, courteous – check, knowledgeable – check, hard working – check, willing to explain the work being performed and make suggestions – check, clean the area upon completion – check. I am very happy with the work done and my expectations were exceeded by the professionals doing the work. Thanks!”



My experience working with your staff has been so pleasant and positive. Kudos to:

  • Aaron & Louie – On time and friendly. Came in, went out, left no mess. They worked well as a team and, best of all, they displayed respect for one another.
  • Karen – Warm and friendly phone voice, and helpful with paperwork. (I have no access to email at the moment.)
  • Patrick – On time. Explained the work and was easy to understand. Shared his youthful history of my neighborhood. Laugh out loud.

Thank you!


“On time! Got the job done!”


“My dealings with Rockweiler Insulation were first class. From my conversations and visits with Pat Harrington to the two-man crew who did the job, to my interactions with you, it was all a positive experience. I especially want to compliment the two installers. They were friendly, efficient, and very respectful of our home. I have nothing but high praise for them.”


“Took the time to investigate and explain.”


“I just wanted to write to express my thanks to the teams that worked on my house today. They were very friendly and able and willing to answer any questions I had. They were careful not to walk on freshly planted grass, and they were careful not to bring dirt into my house on their shoes. I peeked into the basement and was impressed with how thorough they were. Also, I didn’t see any mess anywhere. I’ve had a lot of issues with service providers NOT doing a good job like your team did. So, I felt you and they needed to know I appreciate their work.”


“All around excellence, especially in communications and response time. Our salesman/estimator was fabulous.”


“Just wanted to say how thrilled we were with our interactions with your team. Pat, Larry & ‘Louie’ were great to work with. They were friendly, professional and very detail-oriented. They left a very clean job site.”

“The guys did a nice job, they answered all the foolish questions of an old guy without making me feel foolish. Their people skills add to the customer satisfaction of a job done well.”


“Roberto and Kyle did a fantastic job. They were neat and careful in my home and worked both quickly and efficiently! My space feels warmer already, thanks!!”


“Rockweiler was professional, responsive, clean! Brian helped us understand options and was pleasant and helpful in all our interactions. The insulation made a noticeable difference in our home. Highly recommend!”


“Rockweiler Insulation did a great job insulating my home. The staff was very professional and kind. I highly recommend this company.”


“Larry and Louie did a great job. They sealed box sills (including some in hard to reach areas), increased attic insulation, replaced insulation in other areas, etc. The work was done as scheduled and we’re pleased with the results.”


“Went extremely well. Received detailed email several days prior to scheduled appt. that explained in detail the entire process… customer preparation before installation and what to expect during and post-installation. Crew of two was punctual and polite. Based on visual inspection, it appears they did an excellent and detailed job. I did the pre-installation prep work – i.e., removing old fiberglass insulation, vacuuming out box sill and providing clear pathway of approx. 3-4 ft around walls for crew to maneuver; doing the prep work saved me about $400.”


“These guys are awesome! We recently had the attic space over our garage insulated and I could not be happier. They were extremely flexible with scheduling, and their prices are incredibly reasonable. The team that showed up were absolute machines and got done in no time. The best part of all, they meticulously cleaned the space around them before they left. You may find someone that’s a little bit cheaper, but you will not find a higher quality installation or a better team to work with!”


“Had a decent amount of insulation work to do on my new house, and Rockweiler did a great job. All I had to do was let them in in the morning, show them around the house, and then they quickly took care of everything.”


“Cannot say enough good things about this company! [The] estimator/customer liaison was fantastic to work with and very patient with my schedule changes, questions, etc. He gave sound advice and didn’t use car-salesman tactics. [The] installation crew are top-notch and didn’t leave any details unfinished. This is the company you’re looking for – so don’t hesitate. If it costs a few dollars more, relax. You’re getting what you paid for!”


“Very professional company. Did great work and very efficient. I wish we would have insulated sooner, as it’s already made a huge difference in the warmth of the house and has greatly reduced outside noises coming in.”


“It was fantastic! I have used Rockweiler in the past and have been very pleased. This time I needed insulation work done in an older home. The crew reported for work in a timely manner, were friendly, and finished the job in one day. The most fantastic aspect of my experience was the $400 [credit] they gave me. They had bid a $2,100 job and finished a few hours early. They actually gave me credit for work hours not used. I never would have known the difference and would have happily paid the entire estimate. I give them so many kudos for honesty. I don’t think very many companies would have done this. Thanks, Rockweiler!”


“This was a project I had considered doing myself and after spending some time getting it started, it became apparent that I needed to call someone. I opted to call Rockweiler. The quote can be higher than what you might expect, but as it turns out there is quite a bit more work involved that just blowing insulation in. In terms of time, perhaps the last 15%-20% of the actual time spent on the project is blowing the insulation in. In our case we had Larry and Louie (I hope I have those names right) come to our house to do the work. Prior to starting Larry explained their plan and invited me up into the attic to talk about if I wanted. I left them at their work for about 4-5 hours and stopped back in to check on how things were progressing. Larry was glad to explain where things were at. They were getting close to the point where they’d blow the insulation in and things were going well. I poked around in the attic and noticed the workmanship which was better than what I would have done, and far more complete. I’d even call it impressive. I left the house so that they could wrap up and finish their day. When I came home everything was cleaned up and as neat as it could be. The attic, a sea of insulation. If you are so lucky as to get Larry and Louie doing your work, you are in good hands. Thanks guys.”


“Top notch company to work with! Professional all around from initial inspection and estimate, scheduling, and completion of the job. Knowledgeable staff who are friendly and helpful. Even to the point of recommending things I could do additionally to conserve energy in my finished attic. They were so respectful of my home – not a dent or scratch anywhere and they had to traipse through the house up three stories. Even put plastic down to walk on. A+ company!”


“We have been working with Rockweiler Insulation since 1983 when we built our first home. The company consisted of Gary and a few others at that time. We have continued to work with Rockweiler with our remodeling firm for the past 30 plus years. This staying power is a testament to any company. They have continued to grow and be a leader in the remodeling industry over the years. I am also happy and excited to work with the next generation of Rockweiler and the new face Renee – Gary’s daughter! She has been a great resource and continues to service the industry.”


“I had attic insulation removed and replaced over our family room. The whole team was courteous and professional from the first phone call to the end of the project. They even helped me out by splitting the work over two separate days so that I could have an electrician come into the attic space and install cam lighting and wiring before the insulation was re-blown. It was a great experience all around. And the head installer was very passionate about the insulation. It was nice to see someone believe in and care so much about the product he was selling and installing. I definitely recommend their services.”
