"Jackie Chow was the initial representative we met and he performed an initial inspection and thoroughly explained all of the different options and costs. There were no pressure tactics. Once we had analyzed the info and notified them that we wanted to proceed, the project was scheduled within 10 days. On the day of installation, Hugo and his crew arrived early and began tenting the work area to the entrance/exit points. They removed the old insulation, cleaned and sanitized the attic, sealed the ducts where necessary and re-installed new R38 batt insulation. When finished, the cleaned up the area and were on their way in about 5 hours. No fuss, no mess. I would definitely recommend Insulation Labs"

"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"We hired Pro Insulation about 1 week prior & job completed in 1 day, Jan. 31, 2020. Estimate/inspection performed by co-owner, Michael, who is extremely knowledgeable and offered advice & service that I did not know the attic needed ( we live in an area of high outside summer temperatures [ 110 degrees on a bad day ], but 35 degree and above winter temperatures ). 3 workers arrived on-time with all supplies needed. They prepared the house for repeated entry of workers & bringing-in/taking-out materials. They removed all 1986 old insulation when the home was originally built, vacuumed the attic floor as well as the beam surfaces for old rodent pellets & dust, sprayed entire attic with disinfecting spray, checked the A/C / heater ducting systems for air leaks & taped sealed if needed, they checked for any rodent entry access points and secured them ( I think any access points were found, but two little beasties got in from somewhere? ), installed solid insulation rolls on vertical surfaces, installed thermal barriers on the attic ceiling and then blew-in R-38 cellulose with impregnated boric acid insulation into the attic. The thickness of the blow-in was monitored by placing a tape measure like stick to make sure the insulation was at R-38 thickness. They checked for thoroughness of job quality. They also sealed the exterior chimney-to-attic for cracks and squirted in that foam barrier. They cleaned up the attic, the interior house; the exterior house. Finally, as promised, the other co-owner, Evelyn, mailed us the paperwork to apply for local city rebate as well as the gas utility rebate as well as informing us to check our future 2020 tax preparation for any Federal and/or State energy rebates. Bottom line: I would recommend Pro Insulation highly. The owners are directly involved with the project, completed on-time as promised, workmanship was perfect, and estimate = actual price paid. Full disclosure: I am a repeat Home Advisor customer ( partial re-roof job + repair two exterior iron gates ), but I repeat business with Home Advisor because I trust their vetting system to recommend highly qualified / trustworthy / fair-priced contractors. Would I use: Pro Insulation again - YES / Will I use Home Advisor for some future major project around the house - YES. signed: Scott G., MD in Riverside, CA"

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

"Rob was amazing! I wanted to get my attic insulated, my house was built in the sixties and had never been updated to current standards. Was able to get an estimate within 2 days and when he came he inspected throughout to see if there were other problems which he found from when we replaced out AC ducts. Estimate was extremely reasonable and was able to get a insulation date the following week. Luckily we were able to get this done before the heat waves started and I already have noticed the improvement on retaining ideal temperature and my AC runs much more efficiently and has to run for less time. Cant recommend this company enough!"

FAQs for batt, rolled or reflective insulation install or upgrade projects in Ontario, CA

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
