"We hired Tyson to insulate our exterior walls, remove old attic insulation and seal the attic, and then blow in new fiberglass attic insulation. In the course of removing the old cellulose, they discovered that we had no functioning heat/air duct system, which explained why our power bills were (literally as it turned out) going through the roof. They gave us a lead on a good HVAC service, and were very flexible while we sorted out the problem. Chris as the owner is very conscientious and good to work with, and makes sure his people do the job well."

"We purchased our house last September and with these heat waves weâ ve been having, we quickly found out our home would not stay cool and suspected it was due to the lack of insulation. On the hottest days our house was getting up to 83 degrees even with our brand new AC and a portable AC unit running all day (you can imagine how bad our electric bill is). I called Rodriguez Insulation on a Monday at 1pm and they came out and gave me an estimate the next morning. They showed up on time (which seems to be a hard thing for people to do nowadays), were friendly, and provided me the assessment of my current insulation situation and estimate while on site. They offered the lowest estimate out of all 4 companies I called and provided the best overall service during the estimate process so I chose them to do the work. Their team showed up on the day of the job on time and finished quickly. Overall Iâ m extremely satisfied and would highly recommend them. Itâ s 100 degrees out right now and my home is finally comfortably sitting at 70 degrees!"

"Able to get work done just a few days after contact. No disruption to the household daily routine. Patrick was very easy to work with. Cost was much lower than the one other quote received. Only complaint was that he covered a walkway in the attic that I had requested be left clear. No big deal."

"I'm extremely impressed with Luis and Icon Insulation. After moving into a 115 year old house about 5 months ago, and having a lot of contractors doing various jobs, Luis was a breath of fresh air! I had him Insulate my attic, and then I had him back again to insulate under our floor. I would highly recommend Icon Insulation to anyone I know. They are very responsive and answered all my questions before our appointment, punctual, professional, and have a great work ethic. (Something hard to find these days.) Thank you for your great work!"

"Fantastically well! I would highly recommend America One Insulation to anyone requiring insulation removal and installation. Their team worked non-stop to remove all the old insulation in our attic; putting in a 12 hour day. David, the owner of America One Insulation, followed up prior to the team arriving (a father and son) during the removal process, as well as that evening. One could not ask for a more professional company to do business with."

"Called wed. at 10am after being told by different contractor who inspected attic and walls said walls needed to be insulated, Arron said they happen to be working local and could come and bid wall job in about 45 min.s. When Superior Insulation was inspecting walls asked my renter if they could inspect attic, after seeing attic Arron called and said walls Didn't need to be done. The attic was grossly under-insulated and would cost a lot less to do than walls. I asked how much walls would cost and the price for both was close to other bid for just walls, I told Arron lets just do both and he recommended strongly to just do attic! I happen to be a quad in a chair w/ no way to inspect(Arron had no way of knowing!)attic before I started getting bids. Hired Superior Insulation to do job, they started thur. at 8am by 11 am they were done. Arron sent approx. 20 pic.'s of before and after insulation in attic, during job Superior Insulation found large openings where old wall heater used to be and repaired free of charge! Told Arron it didn't matter but I happen to be a trustee at my church and just had a good feeling about his company and was glad I hired him, at which time he shared he was a newly hired Pastor! Superior Insulation VERY HONEST and VERY GOOD VALUE!"

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."

Insulation questions, answered by experts

When comparing insulation service quotes in Fresno, watch for vague descriptions of work, missing details about insulation materials, or professionals who skip a home inspection. Be wary if a contractor avoids discussing ventilation, doesn’t mention compliance with local building codes, or fails to outline cleanup procedures. Insist on clear timelines and ask about post-installation support to avoid future issues.

Helpful?

In Fresno, homes that experience frequent temperature swings, have older or compressed attic insulation, or show signs of moisture buildup are strong candidates for insulation service. If you notice persistent dust, uneven heating or cooling, or your HVAC system runs constantly, it’s a sign your insulation may be underperforming. Homes built before updated energy efficiency standards are especially likely to benefit from an upgrade.

Helpful?

For Fresno homes, blown-in fiberglass or cellulose is effective for attics, helping manage both heat and air quality. Spray foam insulation is ideal for sealing gaps in crawl spaces and rim joists. Radiant barriers can significantly reduce attic temperatures during hot summers. Always select materials rated for high R-values and ensure they are suitable for the region’s dry climate and energy efficiency standards.

Helpful?

In Fresno, prioritize insulation service pros who demonstrate expertise with local climate challenges, such as extreme summer heat and air quality concerns. Look for contractors who provide tailored recommendations for your home’s construction type, explain R-value requirements, and offer proof of proper licensing. It’s also important they address attic ventilation and provide a clear plan for safe material disposal.

Helpful?

Fresno homeowners often overlook sealing air leaks before adding insulation, which reduces overall energy efficiency. Another common mistake is neglecting to address attic ventilation, leading to moisture or mold problems. Some choose insulation types unsuited for the area’s heat, or fail to verify that installation meets local code requirements. Not scheduling a post-installation inspection can also result in missed problem areas.
