“Our home has been warm and comfortable this winter. It has been interesting getting used to the wide array of control we now have temperature wise. The $10 PG&E bill is a real bonus! We are very happy."
- Joseph & Janet, Santa Rosa
"ABS was delightful to work with. They are thoroughly knowledgeable regarding the seismic hazards here in Santa Rosa, and super professional in getting the paperwork required, getting the building permit, doing the actual retrofitting of my home foundation, and then very quickly having the building inspector come to verify the work. I cannot recommend ABS enough. You'll enjoy working with them, I'm sure."
- Penny G, Sonoma
"The whole ABS team was great. Very easy to work with. Helpful with explanations and answering all the questions that I had. They made working with the city very easy and they did a great job. I now sleep easier thanks to the work they did."
- Matthew R, Calistoga
"With the house air leakage down to 1,100 cfm/50 our house is noticeably more comfortable, and there is less dust as well, since your air sealing and insulation work. Great work. We will certainly be referring you to our friends and neighbors."
- Dick R, Windsor
"ABS completed our Earthquake Brace & Bolt retrofit. Billy and his crew are very highly recommended! They did the bid and the work very professionally and quickly. They worked with us around some difficult scheduling requirements that we had. Their price was good and made the whole process very easy on us. I couldn't recommend them more wholeheartedly!"
- Roger D, Santa Rosa
"If you are going to have your home braced and bolted to your foundation, look no further than the ABS team. They are experience, positive, and very easy to work with. They will do ALL the work for you. I highly recommend ABS."
- William S, Kenwood
"John Sutter and his crew are very professional, experienced, and have done a great job for me. The quote was done quickly and the work went on without a hitch. The end project was very well done and I have no complaints whatsoever. I'd recommend his company to anyone."
- John L, Santa Rosa
"John Sutter and the entire ABS crew are absolutely fantastic, professional, and friendly folks. We needed to completely upgrade our home heating, insulation, and duct work, as well as eliminate tons of air leaks in order to reduce our insanely high PG&E bills and create a more comfortable home environment. I looked at several companies before choosing ABS and I'm very glad I chose John and Applied Building Science. His young crew is the most hard-working, courteous group of guys you could hope to have in your home; everyone is trustworthy and respectful of your space. John also provides a very personal advising service, helping me fully understand all aspects of energy usage and savings in our home. He's very patient and thorough when it comes to explaining the details of the work involved and the technology involved as well. That's commitment!"
- Tom F, Santa Rosa
"John & the crew at ABS have been great to work with; dependable, professional, and attentive. The result for us has been a very efficient solar system, perfectly sized to take care of all our electric needs each year. We have an older house but with careful planning, we've met all our normal electric needs plus air conditioning in the summer and our electric car. The robust monitoring tools allow us to 'see' where and how our use vs. consumption tracks. The first year, with greater than usual car usage, we still nearly 'zeroed out' on our PG&E year-end True Up bill. This year we're going to beat that and end up paying nothing beyond the $10 connection fee PG&E demands. It's very satisfying to run our daily errands in the car, knowing we are running on nothing more than sunshine."
- Chris G, Santa Rosa
"We received the energy rebate yesterday. We have also been enjoying the ability to keep our house warm and cozy this winter without it costing us hundreds of dollars each month in gas charges. As always, a BIG thanks to you and your team for upgrading our home."
- Mathew & Elizabeth, Santa Rosa
"ABS is highly recommended. Excellent experience from bid to final submission. Staff were professional, respectful, and clearly communicated throughout the project. Work was done on time and at a competitive price."
- Lee S, Santa Rosa
"I recently hired ABS to insulate a home that was built in 1925. After interviewing three PG&E-approved contractors, it was obvious to me that ABS was the best choice. Their crew is friendly, clean, competent, everything you would hope for. I am very glad that I hired ABS, glad to have met John, and I recommend them wholeheartedly! Thanks John!!"
- Don G, Sebastopol
"I just finished having repairs done on my home from fire damage here in Coffey Park. I called John Sutter right away for repairs (his company installed my solar 2 years ago) and he was here for a walkthrough within days. His crew were professional, neat, and on time. I would recommend Applied Building Science to anyone in Sonoma County."
- Judy C, Santa Rosa
"John Sutter is a great guy, and his crew did a fantastic job insulating my 100-year-old farmhouse. They paid a lot of attention to detail and went beyond the call of duty. Super professional, super efficient, and super nice people. Highly recommend!"
- Terri D, Sebastopol
"I highly recommend this company. I settled on increasing attic insulation, sealing the whole house (walls, outlets, doors, etc) for leaks, sealing ducts against leaks, and building an attic catwalk to access areas without walking through the new insulation. The understood the science and engineering behind their processes. They were responsible, professional, thorough, and fastidiously clean. Their price was reasonable, and they did all the paperwork and applied for energy conservation rebates for me. A pleasure to work with them!"
- Bruce H, Sonoma
"I am very happy with the quality of service I received from Applied Building Science. I would recommend them for earthquake bracing."
- Louis O, Santa Rosa
"This company was an excellent choice for our attic insulation. The very pleasant crew was unobtrusive and efficient. I was amazed the 'blowing in' process could be so quiet and clean. Not a drop of insulating material escaped the attic."
- Jeanette R, Santa Rosa
"ABS completed the earthquake retrofit on our house. Their communication was timely and helpful, and they completed the job quickly and thoroughly. They also completed all the paperwork necessary for the reimbursement program with the state. I highly recommend their work."
- Linnae D, Rohnert Park
"I was very satisfied with ABS. They were very responsive, professional, and courteous. The workers were on time and I have confidence that they did excellent work. I appreciate that the Seismic Retrofit is complete and I can rest easy knowing my home is secure."
- Rich B, Santa Rosa
"We were very pleased we completed our Seismic Retrofit with ABS. They did everything as promised and their work passed inspection with no difficulty. Everyone we dealt with in the company was courteous, competent, and efficient."
- Maureen R, Santa Rosa
"ABS was very timely and efficient. Easy to work with through the whole process. Would recommend them and actually have already."
- Judy F, Santa Rosa
"Just a note to let you know we are really enjoying the new windows and the lack of drafts we had gotten so used to. I really enjoy going onto the Enphase web site and watching the kilowatts added to our account. At this rate PG&E will owe us money at our true up. I wish we had called you years ago."
- Richard T, Glen Ellen
"5-star satisfaction overall -- the office coordination as well as the 2 person on-site work team were all terrific. While they were working on the Seismic Retrofit, they spotted a plumbing issue while they were working that required fairly immediate repair (a detached drain pipe, so I was able to get a plumber in to get that fixed). 5-star review for them, as well as for completing the work itself in a timely and efficient manner."
- David G, Santa Rosa
"The attic insulation project was completed on March 15th. Work was completed within the timeframe prescribed and in accordance with the contract. I am please with the completed project and I was impressed with the competence of the work crew."
- Richard F, Santa Rosa
"John Sutter from Applied Building Science performed miracles. We first hired John to obtain our building permit for a kitchen and living room remodel after we were unsuccessful in getting the city to grant us a permit after trying for 6 months. John got the permit in 1 week. We completed the project in 6 weeks with excellent results. Instead of finishing with ABS for my next project, I will start with them first. I recommend ABS and John Sutter for any remodeling project."
- Jerry C, Santa Rosa
"I want to let you know I have never encountered such pleasant, thoughtful, professional people as all of the people I have met or had phone calls with, as all of you at ABS. Thank you so much. When I am in need of construction of any kind, they are the company I will call first. Thank you again for a wonderful experience."
- Jo Anne A, Santa Rosa
"They took over my project from another company who couldn't complete the work and they honored our original price, were very communicative, and quick to complete the work. It was insulation in our attic and air leakage sealants. It has made such a difference! They also managed our rebate process efficiently."
- Jessica W, Novato
"We had our home retrofitted by ABS in 2016 and absolutely love our 3-zone all-electric heat pump system. The extra insulation that was installed has kept our home more comfortable and efficient as well. One additional benefit of the whole-house air sealing work was our complete protection from the smoke during the 2017 & 2018 fires. To top it off, John and his crew installed earthquake retrofit measure in both our crawlspace (bolting) and in our garage (sheer-wall). These improvements have really made me feel safer over the past few years. Overall the work was top-notch and our family is so much more comfortable in our home now that all the retrofit work is done. Next we're onto solar PV and maybe even some batteries..."
- B.C., Santa Rosa
"I highly recommend the team at Applied Building Science. I was attracted to their business from the start because they 'get' energy efficiency and optimum building performance. The retrofit only took a few hours; I definitely 'rest' better knowing my house is bolted to the foundation."
- Lenore P, Santa Rosa
"Billy and his team could NOT have made this any easier. They were very communicative throughout the process and attentive to details. The team was professional and tidy. It was an A+ experience."
- James H, Santa Rosa
