Learn MoreReach out by phone or through our contact form. We will ask a few quick questions about your home and what you have noticed - high bills, drafty rooms, or a moisture concern. Most callers get a realistic ballpark on the first call. We respond to every new inquiry within 1 business day.
A member of our team visits your home and inspects the attic, crawl space, or walls - wherever the problem is. We measure what is there, look for air leaks and moisture, and note anything that needs to be addressed before new insulation goes in. You get a written estimate with no vague numbers.
Our crew arrives on the scheduled day with everything needed for the job. We handle permits, inspections, and cleanup. Most homeowners notice a difference in comfort within the first few days, and the impact on energy bills typically shows up in the next billing cycle.
Every project we complete is covered by liability insurance and workers compensation. We hold a California Contractors State License Board license - ask for our number before any work starts. You should never have a contractor in your home without verifying both.
We come to your home, inspect the spaces that matter, and hand you a written estimate with no pressure to decide on the spot. Most assessments take 30 to 60 minutes and give you a clear picture of what the job actually involves before any money changes hands.
We have been working on homes across the Central Coast since 2016. We know the marine layer, the older housing stock from the 1970s and 1980s, the San Luis Obispo County permit process, and the PG&E rebate programs - because we have navigated all of it for our customers.
If your installation has thin spots, gaps, or anything that does not match what we quoted, we return and fix it at no charge. We document every job with before-and-after photos so you can verify the work yourself without climbing into your attic.

"We had a musty smell coming from under the house for years and assumed it was just part of living near the coast. The team found the issue in the crawl space, explained exactly what was happening, and had it sealed and insulated in one day. The smell is gone and the floors feel noticeably warmer."
David R., Arroyo Grande
Crawl Space Insulation
"The upstairs bedroom in our 1980s home was always 10 degrees hotter than the rest of the house in summer. We tried everything - fans, window treatments, nothing worked. After the attic insulation upgrade, that room is finally comfortable. The project was done in one day and the crew left the house clean."
Maria T., Nipomo
Attic Insulation
"I had three contractors come out for spray foam quotes and only one of them actually opened the crawl space hatch and looked around before quoting. That was the team from Nipomo Insulation. They found a moisture issue two others missed. The price was fair and the work was done exactly as promised."

On a 75 degree day in Nipomo, an uninsulated attic can reach 130 degrees or more. That heat radiates straight down into your living space all afternoon. If your AC runs constantly in summer without keeping up, the attic is usually the first place worth checking. The U.S. Department of Energy recommends an R-value between R-38 and R-60 for attics in California's Central Coast climate zone.
Read the DOE insulation guideYes - and it is one of the most overlooked problems in Central Coast homes. Marine layer fog and ground moisture can compress older insulation and create conditions for mold growth in crawl spaces and wall cavities. Closed-cell spray foam addresses both the air and moisture problem at once, making it especially well-suited to coastal climates like Nipomo's.
EPA overview of spray polyurethane foamHomes built in the 1970s and 1980s were insulated to standards that are now well below what is recommended. The insulation that was installed has had decades to compress, shift, or be disturbed by pests. Adding blown-in insulation or spray foam to an older home does not require a remodel - contractors access the attic and crawl space directly. Most homeowners say they wish they had done it sooner.
Pacific Gas & Electric offers rebates for qualifying insulation upgrades in Nipomo. The federal Inflation Reduction Act also provides a tax credit worth up to 30 percent of qualifying insulation material costs. Amounts and eligibility requirements change year to year, so ask your contractor before work begins. An experienced local contractor will know what currently applies and can help with the paperwork.
PG&E energy efficiency rebatesAir sealing always comes first. Without it, conditioned air bypasses the insulation entirely through gaps around light fixtures, pipes, and wall penetrations - and you lose most of the benefit of the new material. A contractor who skips air sealing and just blows in more insulation is not solving the underlying problem. The two steps work together, and a quality job includes both.
After attic insulation, you should not be able to see the wooden joists - the insulation should bury them completely. Coverage should be even across the whole floor with no thin spots near the eaves or gaps around fixtures. Ask for before-and-after photos. A reputable contractor welcomes that request because it shows the work for exactly what it is.

The payback period depends on how under-insulated your home is now and how much your heating and cooling system runs. In Nipomo's climate, homeowners who upgrade significantly under-insulated attics or crawl spaces typically see measurable changes in their PG&E bills within one to two billing cycles. Federal tax credits and utility rebates reduce the upfront cost further.
Fiberglass batts from the 1970s and 1980s have had decades to compress and settle. Blown-in cellulose or fiberglass can shift and thin over time. Spray foam, if installed correctly, can last the lifetime of the home. If your insulation has never been inspected and your home is more than 25 years old, a free assessment will tell you where things actually stand. According to the North American Insulation Manufacturers Association, most insulation should be checked after 20 years.
Uneven comfort - one room always too hot or too cold - is almost always a localized insulation or air sealing problem, not an HVAC issue. Before calling an HVAC technician, have a contractor look at the insulation in and around that specific room. It is usually a faster, cheaper fix than anything the HVAC route would involve.

Nipomo is an unincorporated community in San Luis Obispo County, sitting along the US-101 corridor between Santa Maria and San Luis Obispo. With a population of roughly 18,000 to 20,000 residents spread across the Nipomo Mesa and surrounding areas, it is a community of homeowners - more than 70 percent of households own their homes - which means people here invest in their properties for the long term.
Most of Nipomo's residential neighborhoods were built between the 1970s and the early 2000s, and that housing stock sits on sandy mesa soil that drains quickly but can shift under slabs and foundations over time. Stucco exteriors are common, as are single-family homes on generous lots near landmarks like Nipomo Regional Park, the historic Dana Adobe, and the Guadalupe-Nipomo Dunes, one of the largest coastal dune systems on the West Coast.
The coastal location brings real benefits - mild temperatures, beautiful scenery, and a strong sense of community - but it also means homes deal with marine layer moisture, coastal winds, and temperature swings between cool mornings and warm afternoons. Those conditions make proper insulation more important here than in a typical inland community. Nipomo Insulation has been working onNipomo homes since 2016, and we understand what these houses need - whether you are near the Agricultural land on the east side of town or on the mesa closer to the dunes.
