The right insulation, at the right R-value, installed to even and gap-free coverage — for a home that holds its temperature, costs less to heat and cool, and simply feels more comfortable year-round.

Why It Matters
Heat moves — up and out of your home in winter, down and in through a hot attic in summer. Insulation is what slows that conductive heat flow, and the attic is the single biggest place it happens. When the attic is properly insulated, your home holds the temperature you set instead of leaking it, so your heating and cooling systems don't have to keep fighting to catch up.
Two things decide whether attic insulation actually delivers: the right amount (a sufficient, even R-value with no thin spots) and a clean, air-sealed surface underneath it. Under-insulated, settled, or gap-riddled insulation quietly costs you comfort and money every season. We assess what you have, seal the leaks, and install the right material to the coverage your attic needs.
Material Options
There's no single best insulation — the right pick depends on your attic, your goals, and your budget. Here's a quick, honest comparison; each links to its own page for the full details.
Fiberglass or cellulose blown in to fill the attic floor and hard-to-reach gaps.
Pre-cut fiberglass or mineral-wool batts fitted between joists and studs.
Recycled paper-based loose-fill — the eco-minded option.
Rigid panels for continuous, high-R coverage in the right assemblies.
Dense stone-wool batts for fire, sound, and moisture resistance.
Expands to air-seal and insulate tricky areas in a single step.
Do You Need It?
Insulation is easy to ignore until it's costing you comfort. These are the tell-tale signs it's due for attention.
Rooms never feel right
Rooms that are cold in winter and hot in summer, or that never seem to hold a set temperature, often trace back to thin or missing attic insulation.
High or climbing bills
When heating and cooling costs keep rising, an under-insulated attic is one of the most common — and most fixable — culprits.
You can see the joists
If insulation sits level with or below your attic floor joists, it's likely below today's recommended levels and due for a top-up.
Rodent-damaged or soiled
Insulation that's been matted, soiled, or nested in by rodents has lost its value and should be removed before new goes in.
Uneven floors & drafts
Big temperature differences between floors, or drafts near the ceiling, point to heat escaping straight through the attic.
Old or never upgraded
Older homes — or ones whose attic has never been addressed — are often running on settled, decades-old insulation.
How We Work
Insulation only performs when it's the right amount, evenly installed, over an air-sealed surface. Here's how we handle every job.
We inspect your existing insulation, coverage, and R-value, plus air leaks, moisture, and any rodent damage — so we know exactly where you stand.
We match the right material — blown-in, batt, foam, rockwool, or cellulose — and a target R-value to your attic, climate, and budget.
If the old insulation is contaminated, wet, or rodent-damaged, we remove and haul it away first, then air-seal gaps and penetrations.
We install the chosen material to a consistent depth and full coverage, fitting neatly around obstructions with no gaps or compression.
We confirm the target coverage, clean up completely, and walk you through the finished attic.
Why Attic Pros
For over 13 years, Bay Area homeowners and businesses have trusted us for insulation — because we recommend the right material for the job (not just the priciest), seal the leaks first, install it properly, and stand behind our work.
Real Customers, Real Results
I appreciate the great communication and flexibility. Samim arrived on time and an appointment went well.
I'm very impressed with AtticPros' expediency in scheduling a service call. Samim was courteous, well prepared and knowledgable. He quickly provided a thorough assessment of the situation. What really impressed me is how respectful of the (access through the bathroom) area he was. He cleaned up the attic access door and the (little) fallen insulation on the floor. I highly recommend attic pros for rodent extermination and clean up or any other service required.
Rodent intrusion and the associated damage they cause is the worst! After reading reviews, I decided on Attic Pros because they have great reviews and because they specialize in the work I needed. I was not disappointed. Within a few days of reaching out, Tom came out and did the estimate. The work began only two business days later! The work was scheduled over two days but they did it all in one! The guys arrived on time and were cheerful, polite, and pleasant to deal with. Kevin showed me pictures and video periodically throughout the day so I could see the work, start to finish. He answered all of my questions and explained everything clearly and patiently. Before they left they made sure there was no trash or debris left behind. The crawl space now looks like it belongs under a brand new home, it’s that clean and tidy. I highly recommend Attic Pros for all of your insulation and rodent elimination needs. Update: I came back and edited this, removing a star. The work and workers were great. However, a few days after the job, Julian from their business office messaged me that they had not received payment and the invoice was past due, even though they were paid IN FULL THE DAY OF WORK. Proof of payment was provided and he messaged me that a receipt would be sent when the payment was deposited. Very disappointing and unprofessional of him to go after a customer for payment when the problem lies with their accounts receivable. 10/14/26 I am adding to my review because issues had been discovered over time. They had missed a place where rats were entering, even though they had been out twice to check traps and found some. This guy did a less than thorough cleaning but he did close off the previously missed access point. My rat intrusion problem has been ongoing. 11/6/26 Attic Pros followed through and sent out Raul, an excellent worker, who took care of everything and made it right. While it may have been problematic for a bit, they kept working until it was all made right. They have been kind and communicative, specifically Paula. I will be calling them again in the Spring to work on a different area of my home.
Samim very professional
Did crawl space cleanup and rodent proofing. They were very efficient and thorough.
Samim was great and work very hard. We appreciate him very much.
