Serving San Luis Obispo, CA and surrounding areas. (805) 329-7188
If some rooms run hot while others stay cold, or your PG&E bill feels too high for this mild a climate, your home insulation is the place to start. We assess your attic, walls, and crawl space and fix what is actually costing you money.
Home insulation in San Luis Obispo slows heat from moving through your walls, ceiling, and floors so your living spaces stay comfortable without running your heating and cooling system at full blast - most whole-home assessments can be scheduled within a week and most installation jobs finish in a single day. Think of insulation as a thermal blanket wrapped around your living space: the more complete and even it is, the less your HVAC has to work.
Most homes in San Luis Obispo have insulation in several places - attic, walls, crawl space, and sometimes floors - but that does not mean every area is performing well. Insulation installed in the 1960s and 1970s has often settled, gotten damp from coastal moisture, or been disturbed by pests. It can degrade slowly enough that you never notice a single dramatic change - you just see your bills creeping up year after year. Pairing a home insulation upgrade with our insulation removal service ensures that old, degraded material is cleared out before new insulation goes in.
The U.S. Department of Energy notes that attic insulation delivers the biggest impact on energy bills, while crawl space insulation helps the most with cold floors and moisture control. We assess both areas and give you a clear written recommendation before any work starts.
San Luis Obispo has genuinely temperate weather - summers rarely top 90 degrees and winters stay mild. If your PG&E bill is climbing and you are not running the AC or heat constantly, conditioned air is escaping through under-insulated walls, ceilings, or floors. Homes that should be easy to keep comfortable should not cost much to do so.
Many SLO homes have crawl spaces beneath them. If that crawl space is not properly insulated and sealed, cold air from underneath works up into your living areas overnight. If your floors feel noticeably cold when you step out of bed - even when the rest of the house is warm - crawl space insulation is likely the problem.
If one bedroom is always stuffy in summer while another stays cool, or if your hallway feels drafty while the living room is comfortable, that pattern points to inconsistent or missing insulation. It is one of the most common complaints homeowners describe before getting an assessment.
Homes built in San Luis Obispo before modern energy codes were adopted were often insulated to the minimum standard of their era - well below what is effective today. If you have owned your home for years and never had anyone look at the attic or crawl space, there is a real chance you are losing energy every day without knowing it.
We insulate all parts of the home - attic, exterior walls, crawl space, and floors - using the right material for each location. For attics and wall cavities in existing homes, blown-in fiberglass or cellulose is typically the most practical option because it fills irregular spaces without requiring demolition. For new construction or open wall bays, batt insulation installs quickly and performs well. For areas that also need an air barrier, spray foam seals and insulates at the same time. If your home has old insulation that should come out first, we pair our home insulation service with our retrofit insulation approach - adding coverage to existing finished spaces without major demolition.
Every home insulation job starts with a full assessment. We look at the attic, crawl space, and any accessible wall cavities, measure what is already there, and identify where the biggest thermal gaps are. You get a written report and a clear recommendation before we schedule any work. Air sealing is part of every job because insulation alone cannot stop air from moving through gaps around pipes, wires, and ceiling fixtures - and air movement is responsible for a large portion of heat loss in most older SLO homes.
The highest-impact upgrade for most SLO homeowners - blown-in or batt material added to the attic floor to stop summer heat from radiating into living spaces.
Insulation and vapor barrier installed below your floor joists to stop cold air and moisture from coming up through the floor - especially important in older SLO homes.
Blown-in coverage added to exterior wall cavities through small holes, with no drywall removal needed, for homes where drafts and temperature swings come through the walls.
Sealing gaps around pipes, wires, recessed lights, and attic hatches before any insulation is installed - so the insulation you pay for actually performs as expected.
San Luis Obispo has some of the most comfortable weather in California, which is exactly why poor insulation sneaks up on homeowners here. Because temperatures rarely feel extreme, most residents do not realize their insulation is underperforming until they look back at a few years of PG&E bills and see the trend. Many homes in established neighborhoods like Anholm, Old Town, and the streets around Cal Poly were built in the 1950s through 1980s, when insulation standards were a fraction of what they are today. If your home was built before the mid-1990s and has never had an insulation assessment, there is a good chance your attic and walls are underperforming by current California standards.
San Luis Obispo is also close enough to the coast that marine layer and overnight fog are a regular part of life, especially in spring and early summer. That moisture works its way into crawl spaces and attics, and insulation that gets damp loses a significant portion of its effectiveness - and can create conditions where mold starts to grow. This coastal moisture factor is especially relevant for homeowners in Arroyo Grande and Grover Beach, where homes sit closer to the ocean and crawl spaces are more prone to seasonal moisture buildup. We check vapor barriers and ventilation as part of every home insulation assessment - not as an afterthought.
We respond within 1 business day. The first conversation covers your home's age, size, and what has been bothering you - high bills, cold floors, uneven temperatures. We schedule a free in-home assessment at a time that works for you.
We walk through your home - attic, crawl space, and any accessible wall cavities. We measure what is already there, note its condition, and identify the biggest gaps. You get a written estimate with a clear recommendation before we schedule anything.
Your written estimate outlines what work is recommended, what material will be used, and the total cost. We tell you upfront whether a permit is required - in San Luis Obispo, we handle that paperwork through the city building department. Take your time comparing if you are getting multiple quotes.
Most residential home insulation jobs finish in a single day. For blown-in attic work, you can stay home throughout. Spray foam areas need a few hours to cure before re-entry. Before the crew leaves, we walk you through what was done and answer any questions.
We respond within 1 business day. No obligation - just an honest assessment of every part of your home and a written quote you can compare. Submit this form and someone from our office will call to schedule your free visit.
(805) 329-7188We look at the attic, crawl space, and walls before we recommend anything. A contractor who quotes without looking is guessing. We measure what is already there so the work we recommend is based on what your specific home actually needs.
We hold a current California contractor license and carry full liability and workers compensation coverage on every job. When permitted work is required, a city inspector verifies the installation independently - not just the contractor's word.
We work across San Luis Obispo and all surrounding service areas from a single locally based office. You are not dealing with a franchise or a subcontractor - the same crew that answers the phone does the work.
San Luis Obispo is PG&E territory, and qualifying insulation upgrades may be eligible for rebates. Federal tax credits for energy-efficient home improvements are also available through current programs. We document the work the way these programs require so you can claim what you are owed.
The North American Insulation Manufacturers Association sets best practice installation standards for the industry. We follow those standards on every job because the work happens in places you cannot easily see afterward - and you deserve to know it was done right.
