"We had a rodent infestation in our crawl space and insulation that had been installed upside down, a condition that can cause mold. I chose Atticare because they cleaned up the old insulation and rodent droppings, sealed entry points, sprayed to prevent mold, bacteria and viruses, installed insulation, and were clean. They cost more than other local insulation companies but I didn't have to hire a separate exterminator or worry about mold from the old insulation that was installed wrong. They arrived on time, answered questions and were very easy to work with. I would recommend them."

"Working with Vortex was a great experience. The crew was totally professional and very experienced and did an excellent job spraying closed cell insulation in the new addition to our house. When they were done the job site was left totally spotless. Their prices are very reasonable/competitive. We are very pleased with the work they did and how easy it was to work with them. We will certainly use them again in the future."

Customers say: Quick response

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

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