"I hired Bay Valley to clean out one attic and blow in insulation to the two attics in my home. Joel came out and did a thorough inspection, explaining everything as he went along. the quote was reasonable and fair. Unfortunately, on the scheduled day the team was overbooked and although I had taken the day off, by the afternoon it was clear they would not have time to do my job. Knowing I was disappointed , they agreed to come the next day, which was Saturday even though they don't work Saturdays. Tony and Henry arrived in the afternoon and worked literally non-stop for hours until they got the job done. They were as clean as such a job allows for and when they left the debris was gone. I would recommend Bay Valley Insulation to anyone but I would also be sure everyone was in sync on the schedule."

"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."

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