After 40 years, our insulation was falling off. We also had (they discovered) squirrel damage…read more C.I. had a team of extremely hard-working folks who removed all the old stuff, repaired the squirrel damage, and then sprayed foam throughout our attic. The work was noisy and their workday was long. But worth it. The price was not inexpensive, but we believe for the number of workers, and the extent of the work, the price was fair. It's not something I want to be good at.

Zion Insulators was the most thorough in their estimate, as well as most competitively priced. I wish all our estimates for home improvements had this same combination of quality and affordability. Felix and Jose replaced the fallen baffles, air sealed everything, created a dam for the attic hatch to maximize the insulation around the hatch, brought our blow-in insulation up to R-49, and took pictures of their finished work. The degree difference is now just 3 degrees, and much more comfortable. To top it off, Felix gave me a ring about a month later to see how the insulation was performing, and will stop by to make some very minor improvements around the attic hatch that I would not have demanded or expected. So I give them all the credit for being amazing professionals who go above and beyond. I'd say I did plenty of research, and can recommend Zion Insulators without hesitation. Thanks again!

We figured out that our county's website has a record of all of the permitted work done in the county in the last 3.5 months, and you can sort by project. It also lists the sq footage of the project and the cost. We could see that Kefficient had done the most permitted projects in our county and they had a fair and competitive price compared to other companies who got their work permitted. We ended up deciding to work with Kefficient. What a world of difference! They quickly got a permit and did the work and had it inspected and it looks great. What a relief after such a poor experience with a different company!

The urgency of the work that needed to be done was honored, and end result was even better than my first one!! This was a far more difficult project, and unfortunately, I couldn't be on site during the project. The daily updates with photos and exactly what was worked on (the before and afters) I got was beyond expectations, 1000% to the crew. The light near the dehumidifier is game-changing and they even gave me a moisture monitoring device. When I learned how cool it was, I asked if I can have one for my 1st house, and they offered it to come brin git by(free). Bonus when the technician came to install, he noticed some dropping insulation and just fixed it. This is why I love this company and will always call them for my needs and highly recommend them to anyone.
