"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

"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!"

"Attic Professionals was awesome to work with and highly recommend their business for anyone looking for attic work. We hired his business to replace the insulation in our attic after I took care of a rat issue. We needed all the insulation and droppings removed, cleanse, and replace. Attic Professional crew were diligent with making sure the interior of our home was protected covering the walls and floors to remove the old insulation and did a great job installing the new insulation. Thank you for great service!!!!!!!!"

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

Insulation questions, answered by experts

In San Francisco, be cautious of insulation service quotes that are unusually low or provided without a site visit. Watch for contractors who avoid specifying insulation materials, R-values, or don’t detail attic insulation options. Lack of local references, reluctance to discuss permits, or skipping energy audits are warning signs. If a pro pressures you for a fast decision or omits warranty details, consider other options.

Helpful?

When hiring in San Francisco, prioritize professionals experienced with local building types, especially older or historic homes. Ensure they offer detailed contracts, assist with permit processes, and provide clear warranties. They should understand the city’s unique climate challenges, offer a range of insulation materials, and be skilled in air sealing and ventilation. Transparent communication and a thorough project plan are also essential.

Helpful?

In San Francisco, a frequent mistake is choosing insulation that isn’t suited for the local climate, especially in damp or fog-prone neighborhoods. Skipping an energy audit or neglecting proper air sealing can reduce effectiveness. Homeowners sometimes overlook ventilation needs, which can lead to moisture issues. Failing to verify contractor experience with older homes or missing out on available home energy efficiency rebates are also common missteps.

Helpful?

In San Francisco, homeowners should consider the city’s varied microclimates, which can impact moisture levels and insulation performance. Homes in foggy areas may need vapor barriers and moisture-resistant insulation to prevent mold. For historic properties, limited attic access or unique framing may require specialized solutions. Seismic safety, soundproofing for shared walls, and strict permit requirements are also important when planning insulation upgrades.

Helpful?

In San Francisco, unexpected costs during insulation service projects can arise if attic access needs to be created or framing repairs are discovered. Mold remediation, pest removal, or ventilation upgrades may become necessary once work begins. If asbestos or lead paint is found, safe removal is required. Homeowners should also anticipate permit fees, disposal costs, and thorough cleanup to restore the home after installation.
