"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!!!"

"I wanted insulation blown in above the ceiling of my condo to lessen the noise from my neighbors above. Darren was very responsive and professional and knew exactly what I was looking for. The crew arrived on time, was very nice, and covered the house in plastic sheeting to protect everything from the incredible amount of dust created by drilling dozens of holes in the ceiling to shoot the insulation. Their subcontractor Robert arrived the next day to repair the holes and repaint the ceilings. He also was able to install can lights in my living room (separate job and quote from the job Attic Construction was doing). During installation of the lights, we discovered that some of the cavities that should have been filled by new insulation were not, due to a problem with the old insulation. One call to Darren and the insulation guys showed up early the next morning to take care of it. Robert the drywall guy and his helper Carlos did an amazing job repairing all the holes, you can't even tell that my ceiling looked like swiss cheese at one point. The reduction in sound coming from upstairs is noticeable due to the new insulation and I love my new lights. Be aware though that a job like this is incredibly messy and dusty but Attic Construction OC made it as easy as possible."

"I couldn't be happier with the experience I had with this company. From start to finish, they were extremely professional, honest, courteous, and respectful of our home. They did an excellent job blowing insulation into our attic, and they made sure to keep everything clean and tidy throughout the entire process. What I especially appreciated was dealing with a family-owned business consisting of a father and his two sons. It's refreshing to see a family take such pride in their work and treat their customers with honesty and respect. Their pricing was also very reasonable, especially considering the quality of their work. It's not often you find a company that checks all the boxes: great workmanship, fair pricing, professionalism, and integrity. I would highly recommend them to anyone looking to have insulation work done. They definitely earned my five-star review!"

"I had a free inspection from a member of the professional Attic Insulation Labs team, they told me that I had batts insulation in an unusually-shaped attic. Essentially, they explained, this meant that large sections of my attic were left un-insulated, allowing heat to escape easily. They talked me through the explanation for this phenomenon and then suggested that I get an insulation installation of blown in insulation, as this type is designed to get into all the little crevices and corners that batts rolls cannot. So I went with it! The process was quick and professional throughout, and the team were very respectful of my property, which I appreciate. Recommend them to people all the time – hire Attic Insulation Labs!"

"I’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

"We have a 2 story house, attic spaces above both stories. David Burgess, the owner, responded to my Email enquiry quickly and was out within 2 days. His evaluation of our situation included taking pictures of the areas of concern to maximize our information. He gave us unlimited time to discuss options, varieties of insulation types, make his recommendations. Based upon his recommendations, his experience and obvious depth of knowledge, and a little research I did, we decided to go with him for the project. The solution was blown cellulose for attic floors, fiberglass batts for vertical knee walls, and sealing of all air spaces. The estimate document was thorough, the price was fair. David and his 2 workmen showed up on time, carefully prepared all areas for minimal dust and dirt impact. Throughout the 2/3 of a day his workmen were here David periodically showed up to check on progress. When the work was completed and clean up was done, David was immediately out here to inspect the completed project. We did a walk-through, again he had taken pictures, showed the completed work. Throughout the process everything was clear, up front, the work was done completely according to our agreement. David and his workmen were professional, prompt, very friendly, extremely helpful. Couldn't ask for more. I'm impressed with Elite Thermal, recommend them highly."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Fontana, 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.
