"The crew was in and out in one day and sealed up the attic better than I expected. My PG&E bill dropped noticeably the next month and the cold spots in the hallway are gone. Worth every dollar."
- James R., Monterey - Attic insulation
"I was worried about my crawl space because of the moisture from living near the bay. They checked everything before starting and explained exactly what they were putting in and why. No surprises on the bill, and the crawl space has stayed dry since."
- Sandra K., Seaside - Crawl space insulation
"Our 1960s Fort Ord house has always been drafty in the winter. After the spray foam work they did in the walls and attic, it finally holds heat properly. The difference is real and I wish we had done it years ago."
- Mike T., Marina - Spray foam insulation

Yes, in certain conditions. Fiberglass batts can absorb moisture and lose effectiveness when attics are not properly sealed or ventilated. Closed-cell spray foam resists moisture by design, making it the better choice for crawl spaces and exterior walls in Marina's damp climate.
Almost certainly. Homes built in the 1950s through 1970s were constructed under energy codes that are far below what California requires today. If your home has never had insulation work done, the original material has had decades to compress, absorb moisture, and lose its ability to slow heat transfer.
It does - but the benefit looks different than in a colder city. Marina's marine layer keeps temperatures cool and damp year-round, so your heater runs more than you might expect. Proper insulation reduces that steady, low-level heat loss and can cut your monthly gas bill.
Strong afternoon winds off Monterey Bay drive air into every gap around windows, outlets, and framing. Insulation slows heat transfer, but air sealing is what stops those drafts at the source. Most insulation contractors address both in a single visit. The U.S. Department of Energy has useful guidance on this at energy.gov.
You get a fraction of the benefit. Insulation slows heat transfer but does not stop air movement. If the gaps around your pipes, wires, and attic hatch are still open, conditioned air keeps escaping and unconditioned air keeps entering - no matter how thick the insulation is.
When the existing material is wet, compressed, pest-damaged, or contaminated with mold. Adding new insulation on top of bad material is a short-term fix that traps moisture and reduces the performance of both layers. A contractor can tell you the condition of what is there in a single attic visit.
The U.S. Department of Energy Insulation Guide is a reliable starting point for understanding insulation types, R-values, and where air sealing matters most.
Marina Insulation is a licensed and insured insulation contractor based in Marina, CA, serving the Monterey Peninsula and surrounding communities since 2015. We hold a California contractor license covering residential and commercial insulation work, issued and overseen by the California Contractors State License Board. Over more than a decade, we have worked on hundreds of homes across 12 communities, from older Fort Ord-era houses to newer construction near CSUMB.
Replace when the existing material is wet, moldy, or compressed flat. Add to it when the material is in good condition but just not thick enough. A contractor can tell the difference in one attic visit.
The attic accounts for the largest share of heat loss in most homes, followed by unsealed gaps around penetrations and windows. Crawl spaces are a close third, especially in homes with wood subfloors over uninsulated ground.
Look for written quotes that break out labor, materials, and air sealing separately. A quote that bundles everything into a single number makes it hard to compare. Ask each contractor whether air sealing is included and what R-value the finished job will achieve.
The ENERGY STAR Seal and Insulate resource walks through what well-sealed homes look like and where most heat is lost - worth reading before you get quotes. Ready to move forward? Request your free estimate or call us at (831) 946-0764.
Marina is a small coastal city of about 22,000 people sitting directly on Monterey Bay, between Seaside to the south and Castroville to the north. The city grew up around Fort Ord, a U.S. Army base that operated from 1917 until 1994, and most of the residential neighborhoods here were built to house military families during that era. When Fort Ord closed, the land was repurposed - the largest parcel became California State University Monterey Bay, which now anchors the eastern edge of the city.
The housing stock in Marina is predominantly mid-century construction - stucco exteriors, simple layouts, and building standards from an era that did not prioritize energy efficiency. Many of these homes have little or no effective insulation remaining after 50-plus years. At the same time, Fort Ord National Monument - now managed as public land for hiking and recreation - borders the newer residential neighborhoods that were built after the base closed. These newer homes have different insulation needs than the older military housing. Marina State Beach, running along the city's western edge, means strong afternoon winds and persistent salt air reach most homes in the city year-round.
Living this close to Monterey Bay is what makes insulation a different conversation in Marina than it is in an inland city. The persistent marine fog, salt-laden winds, and coastal moisture pressure create conditions that wear down building envelopes faster and make moisture-resistant materials more important. Marina Insulation works on homes across all of Marina - from the older streets near downtown to the newer developments closer to CSUMB - and understands what this specific climate does to insulation over time.
