Learn MoreReach out by phone or through our contact form. We will ask a few quick questions about your home and what you are dealing with - high bills, hot rooms, pest damage, or something else. We aim to respond within 1 business day and can usually schedule your free estimate within the same week.
A crew member visits your home, walks the attic or crawl space, and measures what is actually there. We check for air leaks, pest damage, moisture, and coverage gaps. You get a written estimate before any work is scheduled - no verbal quotes that change later. The visit takes 30 to 60 minutes and is completely free.
The crew arrives on the scheduled day, protects your home, and installs the insulation. Most attic jobs finish in a single day. Before they leave, they walk you through the completed work so you can see the coverage yourself. If your project requires a permit inspection, we coordinate that for you.
We hold a current California contractor license and carry full general liability and workers compensation insurance. Every job is covered - from the first visit to the final walkthrough.
We come to your home, assess what is actually there, and give you a written number before any work starts. No verbal quotes, no pressure, no surprises on the invoice.
We are a local crew - you are not waiting for someone to drive over Pacheco Pass to get to your job. We know Central Valley homes, local permit requirements, and the conditions that matter here.

Our upstairs was basically unusable every July. After the attic insulation job, our AC actually keeps up now and our last PG&E bill was noticeably lower. The crew was done in about four hours and left the place clean.
Michael T., Los Banos - Attic insulation
We had rodent damage in the crawl space and I was dreading the conversation about cost. They were straightforward - showed me exactly what was there, gave me a written number, and did the work the following week. No surprises.
Sandra R., Merced - Crawl space insulation
I asked three contractors about spray foam for our exterior walls. These guys were the only ones who actually came out and measured before quoting. The price was fair and the foam coverage looked solid when I checked.

Heat radiates directly through an under-insulated attic and overwhelms your cooling system. The fix is usually more insulation and air sealing - not a bigger AC unit.
Open-cell is softer and better for interior walls and attics. Closed-cell is denser, moisture-resistant, and the right call for crawl spaces and exterior walls. The right choice depends on where it goes.
If insulation has been damaged by pests, soaked by a roof leak, or compressed beyond usefulness, adding new material on top does not fix it. Replacement is the right call when the old material is contaminated or structurally compromised.
Yes. The same gaps that let conditioned air escape let agricultural dust in. Air sealing and insulation close those pathways, reducing how much outdoor particulate matter filters into your living space. The San Joaquin Valley Air Pollution Control District tracks how serious the air quality challenge is in this region.
PG&E offers rebates for qualifying insulation improvements in their service territory, which includes Los Banos. Federal incentives are also available. Ask your contractor which programs apply to your project before work begins - not after.
Spray foam is considered a lifetime material. Blown-in and batt insulation can last 20 to 30 years when kept dry. Pest activity, roof leaks, and renovation work are the main reasons to inspect sooner. If your home is more than 15 years old and has never been checked, it is worth a look.

Homes built before the mid-2000s in Los Banos were constructed under much looser energy standards. The insulation installed then has likely settled, compressed, or been disturbed. Having a contractor assess it is the first step. According to the U.S. Department of Energy, many older homes are significantly under-insulated bytoday's standards.
Spray foam is the right choice when you need air sealing and insulation in one step - crawl spaces, rim joists, and areas around pipes and wiring where blown-in material would leave gaps. Blown-in is faster and more affordable for open attic floors with straightforward coverage needs.
Most insulation upgrades in the Central Valley pay back their cost in reduced energy bills within three to five years. Homes with the worst original insulation - and the highest cooling bills - often see the fastest payback. PG&E rebates and federal tax credits can shorten that timeline meaningfully.

Los Banos is a city of about 40,000 people in Merced County, sitting in the western San Joaquin Valley. The city has grown quickly over the past two decades, largely because housing prices here are lower than in the Bay Area. Many residents commute west over Pacheco Pass on Highway 152 to jobs in the South Bay. Summers here are punishing - July and August regularly see highs above 100 degrees F, and the heat is dry and relentless for months at a stretch. That kind of climate puts a lot of pressure on any home that was not built or insulated to handle it.
The bulk of Los Banos housing stock went up during the rapid growth period from the mid-1990s through the late 2000s - mostly tract homes built quickly to meet demand. Many of those homes are now 20 to 30 years old, old enough that the original roofing, HVAC systems, and insulation are ready for a close look. Closer to downtown, you will find older homes from the 1940s through 1970s with original wood windows and aging mechanical systems. The San Luis Reservoir sits just west of the city - a landmark most locals know well. The Los Banos Wildlife Area on the edge of town is another local anchor, known for bird watching and hunting.
Los Banos Insulation is a local crew - you are not waiting on someone to drive over Pacheco Pass to get to your job. We work in the newer subdivisions on the north and east sides of town, in older homes near downtown, and everywhere in between. Whether your home is near Mercey Springs Road or closer to the city center, we know the homes in this area and the specific insulation challenges that come with living in the Central Valley.
