Air sealing stops drafts at the source - around outlets, pipes, and fixtures where heat quietly escapes.

A correctly installed vapor barrier protects your home from the ground up - stopping moisture that leads to mold and rot.

Your attic is one of the biggest sources of air loss. Sealing it before adding insulation makes both perform better.

A technician visits your home to look at your attic, crawl space, or walls. We check what is already there, measure the space, and look for air leaks or moisture issues. You receive a clear written estimate before any work is scheduled - no pressure, no obligation.
Our crew arrives on the scheduled day, protects your home, and installs the insulation. Most jobs finish in a single day. Before we leave, we walk you through the completed work so you can see exactly what was done and ask any questions.
We carry a valid California contractor license and full liability and workers compensation insurance. Every job is covered - no exceptions, no subcontractors cutting corners.
We never quote over the phone without seeing your home. Every estimate comes from a real in-person assessment so the number you get is accurate and there are no surprises on the invoice.
We have operated in Seaside and the Monterey Peninsula since 2016. We know the local housing stock, the climate conditions, and what these homes actually need.
Before the crew packs up, we show you the completed work, explain what was done and why, and answer every question. You will never pay for insulation you cannot verify.

The crew finished the attic insulation in one day, just like they said they would. The house has been noticeably warmer in the evenings since, and I can actually tell the heater is not running as long. The walkthrough at the end was a nice touch - I could see exactly what they did.
Maria G., Monterey - Attic insulation
We had a musty smell in the crawl space that had been bothering us for years. They came out, assessed it, installed the vapor barrier and crawl space insulation, and the smell is completely gone. They explained everything before they started and did not try to upsell us on things we did not need.
Kevin T., Pacific Grove - Crawl space insulation
Our 1960s home was losing heat like crazy every foggy morning. After the spray foam job, the difference was immediate. The walls actually feel solid now and the bedroom that was always cold finally stays warm through the night. Worth every dollar.
Sandra R., Salinas - Spray foam insulation
We respond within 1 business day. There is no obligation and no pressure. Once you submit the form, someone from our office will call you to schedule a free on-site estimate at a time that works for you.

If your attic insulation is thin enough to see the ceiling joists through it, it is no longer doing its job. Insulation settles over time, and anything installed before 1980 has almost certainly lost significant effectiveness.
Yes. Fiberglass batts and cellulose can absorb moisture from persistent coastal air and lose their thermal value. The U.S. Department of Energy recommends checking attic insulation in humid climates - see resources at energy.gov.
Insulation slows heat transfer, but gaps around pipes, wires, and light fixtures let conditioned air escape entirely. Air sealing first, then insulating, is the combination that produces the biggest comfort gains.
Yes, and it is a common approach. Spray foam seals hard-to-reach gaps and rim joists where moisture resistance matters. Blown-in material then covers the attic floor where depth and coverage are the main goals.
The U.S. Department of Energy recommends R-38 to R-60 for attics in the Monterey Peninsula climate zone. Many Seaside homes built before 1980 have far less than that - often under R-11.
Yes. Pacific Gas and Electric offers rebates for qualifying insulation upgrades in existing homes. Visit the{' '} PG&E rebates page to see current programs before scheduling your project.

Do not disturb it. Some vermiculite insulation installed before 1990 was contaminated with asbestos. Have it tested by a certified professional before any work begins.
It depends on condition. Dry, undamaged insulation can often have new material added on top. Wet, moldy, or pest-damaged insulation should be removed first. A contractor should inspect before recommending either.
For blown-in insulation, the installer should leave depth markers in your attic. For spray foam, even coverage without thin spots or gaps is the benchmark. A walkthrough at job completion is standard practice.

Seaside is a coastal city of about 34,000 people sitting directly adjacent to Monterey on California's central coast. The city grew rapidly after World War II to house military families stationed at Fort Ord, and most of its residential neighborhoods consist of ranch-style and tract homes built between the 1940s and 1970s. Many of those homes have never had a significant insulation upgrade - which is exactly the kind of work we do every week.
Most Seaside neighborhoods are within two miles of the Pacific Ocean, and the marine fog that rolls in off Monterey Bay most mornings is part of daily life here. That persistent moisture and salt air is harder on insulation than most homeowners realize. Homes near Laguna Grande Regional Park and throughout the Broadway corridor are some of the most common areas we work in. The Cal State Monterey Bay campus, built on the former Fort Ord land north of the city, marks the northern boundary of our core service area.
Whether your home is near the center of Seaside or out toward the borders with Monterey, Marina, or Sand City, we work throughout the city and the broader Peninsula. Homes here were built for a different standard than what is expected today, and we have spent years helping Seaside homeowners close that gap - with insulation that works for a coastal climate, installed by a crew that knows these neighborhoods.
