"I would've been five stars, but on the final day of the project, the foreman pressured my wife into giving them five stars. Even handing her her phone to practically make her do it right then and there. It made her feel incredibly uncomfortable. It would've been five stars if not for that."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"The work was performed to my satisfaction. The Sam and the crew arrived on time and explained what was going to happen. The crew prepared the house to minimize any dust and went to work. The job was completed in two days. There were a couple of issues during the job, which were addressed in a timely manner. Overall, I am very happy with the work and would recommend American Attics."

Customers say: Quick response

"Juan and his crew were amazing, they did everything as asked. I wasn't exactly an easy customer as I had a custom layout for my airducts and they knocked it out perfectly within a day when other estimates said 2-3 days and for a fraction of the cost. Started out as a DIY, so I had most of the material and they made it work."

"Very messy project. Just be prepared. While inside my house plastic and tarps covered everything. And place was clean after work done. I have 2 attics. The other is on the garage. I didnâ t think that I should have asked for tarps to cover the stuff in my garage. There is fine particulate matter everywhere! Will take me a long time to return to normal. Not their fault but mine. Showed up on time, worked hard, insisted I climb in attic to see what they had done. My house and the lawn â stagingâ area was immaculate after they left. Highly recommend them."

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