We had a wonderful experience with Prudent Homes. We hired them to clean out and re-insulate the attic, and their attention to detail was wonderful. Furthermore, they were above and beyond, helping us to reinstall the floor after they had taken it to seal the joints below. They even extended the floor to give us extra room for storage. They worked nonstop from 7 AM till 6 PM. Edgar, The project manager was phenomenal and David, the owner, was extremely helpful.
I recently had the pleasure of working with Prudent Homes Insulation to replace the insulation in my attic and I couldn’t be more satisfied with the entire experience. David (the owner) came to give the initial estimate and his knowledge, experience, and expertise were immediately evident. He shared valuable information about all of the different insulation options to help me make my decision. The estimate he provided was very fair – $1,700 less than an estimate I received previously from another company for an 850 sq/ft attic. The work I had done included: vacuuming out the old cellulose insulation, re-connecting all of the bathroom vent pipes running through the attic, prepping the attic with anti-bacterial and anti-pest treatment, spraying closed-cell foam insulation, installing a pull-down staircase, and relocating a recessed light that needed to be moved. From start to finish, David was easily reachable, responsive, and accountable. The insulation team was punctual, thorough, and precise. They finished all the work in two days. I felt that they completed the job efficiently without cutting any corners, and the workmanship/results exceeded my expectations. I highly recommend David and Prudent Homes Insulation to anyone in need of insulation services.
We had an excellent experience with Prudent Homes! They removed our old insulation, sealed the attic, and installed new fiberglass to improve comfort throughout our home. The owner, David, was professional, thorough, and transparent—his quote was fair, and he promptly answered all our questions. His crew (Eduardo, Yonathan,and Samuel) were polite, efficient, and kept us informed every step of the way. Quality work at a fair price—highly recommend!

The whole insulation experience with Comfenergy was well organized and professionally completed on schedule. We immediately felt the difference and the room temperature held to the thermostat settings. Our electric bill is lower. It was worth the investment.
We contracted with Comfenergy for insulation removal, air-sealing, and new insulation at a historic hotel renovation we are managing while the building remains occupied. Access was difficult and we had to protect finished areas and Guests below. Their crews showed up consistently, worked clean, coordinated with other trades, and stayed on schedule. They installed an attic catwalk system, sealed penetrations properly, and completed the work without disrupting the hotel's operations. We had zero issues during the project and the Owners are extremely satisfied with the results. I would absolutely hire them again for future projects.
We chose this company based on some coworkers recommendations (I am a licensed realtor of 20 years in this area) and the crew went above and beyond expectations. Final product (new attic insulation) replaced what was most likely original insulation, is now to code for our county and will pass any home inspection. I had quite a lesson on attics from this company and learned a lot during the process. We also want to give a special shout out and thank you to Carlos on the install team. He noticed some electrical items that needed to be addressed in the attic before new insulation went in, otherwise we would not have known. I was able to bring in a licensed electrician to get the work done. Thank you Carlos!!

Eko Smart Solutions came to insulate my attic recently, the team was polite and efficient. They were responsive to my questions, adamant about providing answers to all the questions I had, they even walked me through the process providing transparency. I appreciate how professional they were. I highly recommend this company for anyone looking to save on their energy bill.
Completely satisfied with the attic insulation project done for my home. Very professional team who knew what they were doing. Daryl was thorough and addressed all my concerns during the inspection and provided a quote no one else could could match even close. Tanja was very responsive and kept me updated with scheduling and implementation. Would highly recommend them.
They came out on time and gave a detailed and reasonable insulation quote, but more importantly they also addressed the attic ecosystem via simple air sealing / baffles, as humid hot attics cause serious damage to both roof wood and shingles, which I had no idea until my roofer said the same thing.
