Retrofit insulation adds material to your existing home - attics, wall cavities, and crawl spaces - without requiring a major renovation. For Santa Rosa's large stock of pre-1980 homes, it is the most practical way to close the performance gap between an older house and a new one.
Retrofit insulation means adding insulation to a home that is already built - without tearing down walls or starting a major renovation. Contractors blow, spray, or inject material into existing spaces like attics, walls, and crawl spaces through small openings. The goal is to fill the gaps that are letting your conditioned air escape and outside temperatures creep in.
Much of Santa Rosa's residential housing stock was built between the 1950s and 1980s - before California adopted the energy codes that require adequate insulation in new construction. Homes from that era were often built with little or no wall insulation and minimal attic coverage. If your home was built before about 1978, there is a good chance it is significantly under-insulated by today's standards. The EPA estimates homeowners who properly air seal and insulate can save an average of 15% on heating and cooling costs - and in a city with Santa Rosa's climate range, that is a meaningful number on a real monthly bill.
Retrofit work pairs naturally with a whole-home insulation assessment - so every area of the building envelope is evaluated together before deciding where upgrades will make the biggest difference.
Santa Rosa summers regularly push into the 90s, and if your home cannot hold a comfortable temperature even with the air conditioner working, heat is getting in through an under-insulated attic or walls. Upstairs rooms and rooms with south-facing walls that feel significantly hotter than the rest of the house are your insulation telling you it needs help.
If your PG&E bill jumps noticeably in July and August and again in December and January, and you have not changed your habits, your home is likely losing conditioned air faster than it should. Comparing bills year over year is one of the easiest ways to spot the pattern.
If you have lived in your home for years and cannot recall any insulation work being done, and the house is from the 1950s through 1970s, there is a good chance your attic has far less coverage than it should. Opening your attic hatch and shining a flashlight across the floor confirms it - if you can see the ceiling joists clearly, you almost certainly need more.
Homes in neighborhoods adjacent to the 2017 Tubbs Fire burn zones were sometimes exposed to extreme heat even if they did not burn. Insulation in attics and crawl spaces can be damaged or degraded by prolonged heat exposure without any visible sign from inside the home. If your home was in a high-risk area and has never been inspected since, it is worth having a contractor take a look.
We respond within one business day. We ask about the age of your home, what areas you are concerned about, and any specific comfort problems you have noticed. This takes about five minutes and helps us arrive prepared.
Before any work is quoted, we visit in person. We look in your attic, check your crawl space if you have one, and may use a blower door test to measure air leakage. This takes 30 to 60 minutes and is the foundation for an accurate quote. Be cautious of any contractor who gives you a firm price without seeing the home first.
After the assessment, you get a written quote that explains what areas will be treated, what material will be used, and the total cost. We flag any permit requirements and handle the permit application if one is needed. Compare two or three quotes before deciding.
On the day of the job, the crew seals gaps first, then blows or sprays insulation material to the correct depth. Most jobs complete within a few hours to a full day. At the end, we walk you through the coverage, clean up equipment, and leave you with documentation of the work completed.
Free on-site assessment. We look at what is actually in your attic and walls before recommending any work - no phone quotes.
