"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!"

"Work I needed done: * Attic Rodent Proofing * Attic Duct Replacement (from aforementioned rodents) * Attic Insulation Replacement * Attic Cleaning * Crawl Space Rodent Proofing * Crawl Space Insulation Replacement * Crawl Space Cleaning * Crawl Space Vapor Barrier Installation * Crawl Space Dehumidifier Installation I was able to schedule a time for them to come visit the property to get a detailed quote very easily through their website. Jeremy was punctual and respectful when visiting the property. He was able to quickly assess the current state of the attic and crawlspace and provide a fair estimate. He was also very knowledgable in advising me on additional steps that I could take to further protect my property. Jeremey also did a great job deciding on the type of insulation and vapor barrier that will be installed that would result in long term success in taking care of my property. Jeremy continued to be very responsive in answering my questions throughout the rest of the process. Omar was the foreman on site, he and the rest of his team were also incredibly respectful and worked diligently over the course of 4 days to finish up the project. Omar did a great job communicating work that had been completed each day as well as any observations he made in the attic and crawlspace. He and his team did a great job protecting the property while they completing their work. If I have any attic or crawlspace needs again I will absolutely reach out to Attic Pros and ask specifically for Jeremy, Omar, and his team. I will come back and update this review with before / after photos."

"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."

"Cruz the Estimator was very helpful answering all my questions when I was trying to decide whether to hire Coast Bldg. Products. When it came time to make an appointment to do the installation of my attic insulation Dominic called to say they had a cancellation and could send someone out the next day. The two men Jose and Rickie were on time, friendly and did a great job. I will definitely tell my friends."

"We just had Attic are done and attic insulation job in our home, and we could not be happier with the overall job, their professionalism, and the quality of the work that they performed. Frandi and his crew of four cleaned (vacuumed) our attic of all the old blown-in insulation and any debris that might have been residing up there. They installed batt type R-38 insulation along with a whole-house in-attic ventilating fan. They protected all surfaces to avoid damage during the install and completely and spotless up everything after the installation. My wife and I would highly recommend this company."

"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."

"From estimate to job completion, very satisfied with the professionalism demonstrated by this company. The job was completed with the installers arriving on time. I appreciated the fact that they wanted to leave my home and walls clean of scuff marks that could be caused by their equipment. Good job and thanks!"

"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."

"I hired Attic master to come over and check the attic for some bad smell. Adam came over to my house and went up to the attic and checked the problem there... He recommended me to remove the old insulation and to place a new one. His price and warranty were good... so i hired them. The following morning, he came over with his worker and took out all the old insulation while his worker placing the new one. The work was completed the same day and the problem of the bed smell has been solved."

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.
