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.

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
We recently had our attic and under our house taken care of and Attic Pros did a great job. Shout out to Amilcar and Walter. Thank You.
Shah turned my experience around from a bad one to a good one in the very beginning. Aleksandra at the office answered and addressed all my questions and concerns very thoroughly. Jose who did the rodent proofing, answered all my questions and took his time going through the crawlspace and making sure he found and covered all potential access points for rodents into the crawlspace. He was very patient and thorough.
Just had a great inspection from Tom. Very informative and helpful!
Dennis is extremely professional, communicated all that was happening, explained where the critters were invading and did a very thorough job sealing the house, along with his helper. Thank you!
Denis, German,& Alexander were great. Very professional, thorough and customer oriented. I would recommend them for any attic, crawl space, HVAC, insulation, rodent & sub pump work. They were nice, hard working & non intrusive.
Tom was professional, knowledgeable and efficient. I got the quote fast and I look forward to Attic Pros doing the work.
