What Mountain View Homeowners Say About Topside Attic Insulation Mountain View
We’ve insulated and sealed more than 9,000 homes since 2016, and every one of them closed with a Documented Photo Record and a written price agreed to before we started. Reviews don’t come from asking nicely. They come from showing up on time, sealing the attic floor before blowing a single bag of insulation, and handing the homeowner a blower-door printout that proves the number changed. In Mountain View, where 1950s ranch homes sit next to new construction with completely different envelope problems, that kind of specificity matters. Here’s what neighbors are saying after we finished their jobs.

Wes walked our attic in the Rex Manor neighborhood and pointed out every top plate gap and the old can lights leaking conditioned air straight into the roof cavity. His crew spent the first day sealing, then blew in GreenFiber the second day. The blower-door test started at 3,800 CFM50 and ended at 1,900. We got the photos, the printout, and the written warranty before anyone packed up. Our PG&E bill dropped $87 the first full month.

We bought a 1962 Eichler on Easy Street and the original fiberglass batts were compressed to about R-11, full of rodent droppings, with gaps at every electrical penetration. Topside didn’t just remove and replace. They sealed every penetration with fire-rated caulk, installed baffles at the eaves for ventilation, then blew in Owens Corning ProPink to R-38. The written scope said exactly what materials and what R-value. The after photos showed every bay filled level. No guesswork.

Three other companies quoted us spray foam in the crawl space without mentioning the dirt crawl was vented to outside air and had zero vapor barrier. Wes explained why foam on the underside of floor joists would trap moisture against the wood in Mountain View’s clay-heavy soil. We went with full encapsulation instead: 20-mil vapor barrier, sealed piers, R-10 rigid foam on the walls, and a dehumidifier. The relative humidity dropped from 78% to 52% in two weeks. He saved us from a mold problem we didn’t know we were about to create.

Our 1978 split-level in Waverly Park had hot second-floor bedrooms every summer and cold ones every winter. Two previous contractors had blown more insulation into the attic without ever checking if the soffit vents were blocked or the kneewalls were open to the attic. Wes found both problems in ten minutes. His crew installed radiant barrier on the roof deck, rebuilt the kneewalls with rigid foam and sealed top plates, then added blown-in to R-49. The temperature difference between floors went from 14 degrees to 4 degrees. He showed us the thermal images. The hot spots were gone.

We got a quote from another company for $4,200 to “add more insulation” to our attic. Brought it to Wes for the Free Second Opinion. He climbed up, found the existing insulation was R-19 fiberglass with the paper facing down, trapping moisture against the drywall every winter. Adding more on top would have made it worse. His written scope was removal, mold remediation, air sealing, and new blown-in to R-38 for $3,800. The other company never looked at the facing direction. Haven Standard Clause 1 means you get the real problem identified before you pay.

After a home energy audit from Topside, we understood why our 1948 cottage near downtown Mountain View never held temperature. The audit found unsealed recessed lights, a chimney chase open to the attic, and a bathroom fan dumping moist air into the insulation. Wes’s crew fixed all three, then dense-packed the walls with Rockwool and blew R-44 in the attic. The blower-door number was cut in half. We keep the printout on the refrigerator. When people ask why our house is comfortable, I hand them Wes’s card and tell them to ask for the second opinion.

Why Customers Trust Us
Every review above mentions the same elements because they’re not optional extras. They’re how we work on every job in Mountain View. Seal first, insulate second. Air sealing of top plates, can lights, and penetrations happens before any insulation goes in. The blower-door test gives you a single number that proves the envelope tightened. The Documented Photo Record shows you what changed. The written price and written warranty arrive before anyone lifts a tool, under Haven Standard Clause 1. And if something isn’t right in the first year, the 365-Day Done Right Promise means we come back and fix it.
We’ve worked in Rex Manor, Monta Loma, Springer, Waverly Park, and across Mountain View’s full range of housing stock, from Eichlers with flat roofs to post-war bungalows with vented attics that haven’t been touched in forty years. The clay soils in the eastern neighborhoods create different crawl space moisture problems than the sandy loam near the bay. We adjust the solution to the actual house, not the template.
Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary lock-in means we specify what performs for your specific assembly, not what moves our inventory. Calls are answered by a live person, 24/7, and our technicians are background-checked and uniformed. You get a text when your technician is on the way, with a name attached.
If you’re comparing quotes or just suspect your attic isn’t performing the way it should, call (669) 259-0406. We’ll schedule a visit, give you a Free Second Opinion on any written estimate you’ve already received, and show you exactly what we find. The written price comes before any work starts. Always.
