“We have used DeVere insulation on all of our rehabs. They communicate very well and their pricing is great. Would always recommend to anyone looking to insulate their homes.”

“Marcus is great. Dealing with this office is always a breath of fresh air for me. They are consistent, very responsive. I have a lot of work on the eastern shore I prefer working with this office. Brittany is amazing also.”
Tamara, The Myers Group LLC

“They are very reasonable in price and get the job done right!”

“DeVere was recommended but I attempted to deal with two other companies for my attic/roof spray foam repair job. I was crazy to even think of dealing with others.

One spray foam company wanted a dozen pictures and other details and then estimated the spray foam job over the phone at double what DeVere did for a full in person estimate. That other company never returned my messages after giving me the I don’t want that job price estimate.

One other company took so long to give me an estimate that DeVere had already done the estimate and job before they could get out to provide an estimate.

DeVere’s whole team is very professional, good timely estimate, quality spray foam job, great prep and clean up. I couldn’t ask for a better experience.

I can now install my fiberglass insulation and drywall in my garage after my roof repairs. Thank you so much team DeVere.”

“Worked with Bert to have the attic of my 100-year-old row home insulated and made habitable. Very easy to talk and work with Bert and his team. Final product was excellent and was the lowest price I received by a considerable amount.”

“Wonderful company Markos was very helpful, courteous and professional. I would recommend them to anyone for all insulation needs. I rehab properties and am a licensed realtor that works with investors and will be referring all of my business partners to Devere.”

Tim, customer

“They did a fantastic job spray foaming R45 in walls and 15 inches of insulation in the attic of my new pole barn garage! Eight hours and done for less than I could buy just the materials.”
Stephen, homeowner

“I did my homework, called all the contractors and DeVere was the only one willing to work with me and my schedule. I had 360 sq. ft. of spray foam done. They were among the most competitive prices and had great communication. Bert was always quick to respond. Support this small business!”
Josh, homeowner

“I had DeVere Insulation come out and give me an estimate for my attic. They were the only company that would work with me on what I wanted. The crew came out on time. COVID READY (masks etc). Very respectful of my furniture and home. And, very friendly. I showed the crew what I discussed with the representative. They went to work. When they were done, we went up into the attic. I was very happy with the work. They did exactly as I had requested. When finished they cleaned up. Thank you DeVere. I will recommend you to my friends and neighbors.”
Liz, homeowner

“I have used DeVere Insulation for over 25 years they’ve always given me a great price and do a very good job. I have seen some bad reviews on here, that’s crazy! But I will say things happen and believe me out of all the companies I tried DeVere is the best out there. Thanks DeVere, you will always have my business.”
Bob Tuttle, Bob Tuttle Roofing

“I bought a 1924 home in Halethorpe. Insulation was a nightmare. Summers upstairs were 90+ with a window unit in. Winters it was always freezing in my home and my BGE gas bill was over $230 a month! So far this past summer was AMAZING!!! Used $30-40 cheaper every month and the upstairs is easier to keep comfy! My heat is awesome! You all did above and beyond what was asked!”
Michael, homeowner

“DeVere does NOT cut corners!! After receiving an energy audit from JT from Greenworks Systems DeVere quoted me to insulate my attic and basement. (1920’s farmhouse with very little/no insulation.) I received 75% rebate to do the work from BGE. DeVere got me in the schedule within 5 days of calling. They were here for two days. One day was the attic and one day was the basement. Miguel the crew leader was extremely professional and courteous. They did an amazing and thorough job redoing my entire basement and attic insulation. I’ve already recommended them to multiples friends who are looking for the same type of work.”
Chris, homeowner

“Knowledgeable insulation people.”
Greg, homeowner

“I had a garage insulated with foam, and portions of my attic done by DeVere Insulation. I couldn’t be happier. Mike came out and did an estimate and, along with Diana and Michelle, was my point of contact for all aspects of the project. They were professional and personable every step of the way, and were very accessible to answer questions, work with my schedule, and ensure the job was completed as promised. The crew that came out to do the work were extremely nice, polite, and competent, and were great representatives of what is obviously a well run quality company. I’d use them again without reservation for another insulation job, and highly recommend them if you need that type of work.”
Mark, homeowner

“Mike has been working with us for years on various projects and they are always top notch!”
Alexander, contractor

“Very reliable insulation company. I had all four floors of my exterior walls insulated, including closed cell spray foam in the basement. I had my ceiling insulated in each unit and the roof with R-38 and R-49, respectfully, and the total cost was $5,600. Great deal. They were professional and in/out in a few hours. Suggest using them if you’re insulating your home.”
Larrien, homeowner

“DeVere removed and installed insulation under the extension on our house today. As they say, ‘happy wife, happy life’ — my wife is thrilled at the work done. Workers were on time, efficient and clean. Great job, [employee] and entire crew.”
Daniel, homeowner

“We don’t actually get to see your handiwork, but I can tell you that we’re sure grateful for your effort and work on our house. Please know that we’re very aware of your level of professionalism and that you’re simply very good at what you do — and we’re grateful.”
John and Trish, homeowners

“I was very impressed by [the installers] who came yesterday to do the spray foam insulation. For starters, they had to back the truck down a narrow alley, and it was an especially tight fit right at the beginning. Most drivers would have quit, but [the driver] patiently navigated the tight passage with [the other installer’s] guidance. Once the truck was situated, they viewed the workspace and asked detailed questions to make sure that the job would be done to my expectations. They promised to do a good job and also said they would be sure to clean up after themselves. When they were finished, I came back to have a look; they had done very thorough work and had cleaned up completely. I deal with a lot of contractors on a regular basis, and I can say this was one of the most pleasant experiences I have had in a long time. They were polite, professional, and clearly were committed to doing a good job, and it was a pleasure having them do the work. I will certainly request them for my next job with DeVere.”
Tom, realtor

“Great service and quality product and insulation.”
Jason, homeowner

“This company was recommended to me some time ago and I used their service. At that time I received excellent service, everyone showed up on time, the job was done within one day and I was very satisfied.”
Anthoni, homeowner

“A+++ Can’t say enough great things about DeVere. Every part of the organization has been a pleasure to deal with. Estimate was timely and accurate. Payment is easy and admin response is always friendly and prompt. The workmanship is phenomenal. DeVere installed all new insulation (Batt & Spray) in my 3,100 sq ft home renovation. Always showed up to work on time and completed the Batt install in ONE DAY! I was amazed. They are efficient (2-3 crew members stayed on site at all times, while another employee brought them a new truck full of material when they depleted the first)!! No hidden fees or up charges. Crew did a walk through with me at the end of the day and gave me the opportunity to identify any issues and they would fix. I would definitely recommend DeVere for your insulation job and they will take care of you. Pricing is competitive and they are a great company to deal with. Thanks so much for everything!”
Henry, homeowner

“I highly recommend DeVere, They are dedicated to providing their clients with a superior level of customer service. They go beyond the basics. You can count on that the projects are going to be well managed, from start to finish.”
Att, homeowner

“I had this company come out earlier this year to install insulation in my attic. I thought they would try to sell me the most expensive thing in the pamphlet as most companies do, but they didn’t. They informed me of what I currently had and advised that it would be much easier to just add onto it. There were a few other things brought to my attention that I needed done and they were shown to me in pictures taken by the person doing the quote which I thought would be extremely expensive. She explained to me why I needed these things done and said she would send me a quote. When I received the quote, I was shocked. I thought they missed something. I called to ensure everything she said was included in the quote and it was! When the guys came out to install everything they were professional and very polite. Since getting the insulation installed and other work done, I have saved what I spent in BGE bills already and we aren’t even through the summer yet! I can’t say enough good things about this company!”
Erin, homeowner 

“It is with a heart overflowing with gratefulness that I am writing to thank you for your support of Harvest House. Because of your generosity and kindness our renovation plans have become reality. We look forward to offering men in the stronghold of addiction an opportunity to rebuild and restore their lives. Please pray for us as we continue our journey and for the men God is calling us to serve.”
Donna Sheldon, President Harvest House 

“They were very accommodating to us. We had specific needs and they met them. They were on time and finished the job perfectly and in a timely manner. Their charges were very reasonable.”
Flair Interior Design

“DeVere came and insulated my house on a rainy cold day. They did a great job on the insulation projects and left no trace that they had been there despite the weather. They even reduced the price a little when they realized that they did not have to do the same amount of work as had been bid.  All in all a very good experience.”
Michael, homeowner

“A job well done — we would recommend DeVere to family and friends. They were very helpful in working with BGE for energy rebates. The crews work hard and they take pride in their work.”
Marianela, homeowner

“I live in a really old home. DeVere was highly recommended to me. They came out this past week and insulated my home. The people who work for this company are tops — they were extremely knowledgeable, worked hard and got the job done quickly.  I highly recommend this company!”
Kathie, homeowner

“Very professional and quick installation. The crew was clean and courteous. I’ve seen a dramatic reduction in energy costs for my home.”Christopher, homeowner 

“Both crews that came out to encapsulate my crawl space were professional, polite, and courteous. Both crews explained all the work [they] were doing before and after. They removed all the old material and made sure they didn’t leave a mess. They did [an] outstanding job and I would highly recommend DeVere service.”
Travis, homeowner 

“Excellent! They were prompt, courteous and clean! They made sure to include my input every step of the way and checked with me upon completing each step.”
Joseph, homeowner 

“As a contractor, I have relied on DeVere to consistently provide me with high-quality air sealing and insulation work. I can count on DeVere’s crews to show up on time, work with a positive attitude and stay until the job is finished — all for reasonable prices compared to the competition. The air sealing and insulation crews are truly experts at what they do, which is difficult work, often in confined spaces. An excellent company; highly recommended.”

“I just wanted to let you know how satisfied I am with the job your company did. The workers were very considerate and cleaned up completely after themselves. From what I can see, my house is now all sealed up and well insulated, and in the unfinished basement, they did even more around the rim than I expected. Best of all, I can tell the sealing and insulation in the attic has helped me air condition the upstairs — previously, I would have to really turn down the thermostat to get the upstairs to cool, but now, I don’t have to have a freezing downstairs in order to get a comfortable upstairs.”
Thank you!
Virginia, homeowner 

“Company did a lot of insulation work. Workers were skilled and followed the recommended procedures. They arrived on time and worked steadily throughout the day and into the evening to complete the job. They came back a week later to complete a small portion of the job that was not finished according to the contract. They were very neat and cleaned up well.”

“I found everyone with DeVere Insulation professional, knowledgeable and very helpful. My sales rep was extremely helpful in answering all of my questions and a pleasure to deal with. My home is old and the installation complicated so she sent a supervisor to inspect the worksite before DeVere sent a work crew. The installers and supervisors were great. They arrived on time, worked a long day to complete a very complicated job in my house and cleaned up before they left. I could feel a difference in the air in my home immediately. I’m looking forward to seeing the difference in my energy usage. I am happy to recommend DeVere Insulation Company. I think they did a great job.”
Susan, homeowner 

“I want to commend everyone in your operation…for providing superior service in my fairly complex old house. I had no idea how involved the job would be.  I have been most impressed with everyone’s knowledge and performance.  Each person has been thorough, polite, on-time, excellent communicators, respectful of my home and careful to leave things in good condition.  While they are not completely finished… the foreman, and his crew are all doing excellent work.”
Cathy, homeowner 

“I rate this company an A+. Management was extremely helpful. Workers were on time, extremely neat, and competent. All work contracted to be done, was done. In conclusion, it was a completely satisfactory experience and I highly recommend them without reservation.”
Joseph, homeowner 

“The guys from DeVere did a great job. They really went the extra mile to hit every joint with caulk and in the basement they sealed every rim joist. My house is very difficult and complicated and pretty large so there was a lot of work to do. I was very pleased.”
Richard, homeowner 

“Just want you to know we really feel the difference in our laundry room, entryway and kitchen…warmer! I want to commend your work and the work of all the guys here at the house. Wouldn’t have even known that we had workers in the house or garage. Everything was left so clean. I look forward to getting the crawl space done also. I will sing your praises to everyone I meet!”
Cathy, homeowner 

“When we have a job on a tight schedule… we call DeVere.”
Brian, contractor

“Our specialty is framing and drywall, not insulation. DeVere has the knowledge when looking at the specs and asks the right questions. If we did it our guys could [do it incorrectly], and we’d have to do it over and over until it was right. We call DeVere and it gets done right the first time.”
Rob, contractor

“Dependability, competitive pricing, quality control. I don’t have to call [DeVere] 15 times and say ‘Why’d the insulation fail inspection?’ You’ve got good guys that care about their quality of work.”
Rick, contractor
