Frequently Asked Questions

We seal first, then insulate - in that order. The crew removes old material if needed, seals all top plates, can lights, chimney chases, and duct penetrations with fire-rated foam and tape, then blows new insulation to the depth specified in your written scope. Every job ends with a blower-door test comparing before and after numbers. You get photos of what we found, photos of what we did, and the test results in a shared folder before we leave.

Most residential jobs in Campbell, Los Gatos, and Saratoga finish in one day. Larger homes in Monte Sereno or multi-story properties with complex attic framing may take two days. We give you a real arrival window, a named technician, and a text when they're on the way - Clause 2 of The Haven Standard. Weather rarely delays us since attic work is interior, though extreme heat in July and August sometimes shifts start times earlier in the day.

Someone over 18 needs to be present at the start to review the written scope and sign off, but you don't need to stay for the full installation. Many Campbell homeowners who work in tech leave after the walkthrough and check the shared photo folder at lunch. We text when we're done and schedule a 15-minute closeout call or in-person review to review the blower-door results.

Clear a path to the attic hatch and remove stored items you want to keep. We move what we need to, but we don't organize your storage. If your hatch is in a closet, pull clothes back. In Campbell's older homes near the Pruneyard, we've found hatches buried behind built-in shelving - let us know if access is unusual when you schedule. We bring drop cloths, HEPA vacuums, and containment for the work zone.

It often helps significantly, but it's not always the full solution. Hot second floors in Campbell's 1960s-1980s subdivisions near West Campbell usually trace to three issues: insufficient attic insulation, unsealed ductwork in the attic, and missing or inadequate attic ventilation. During your free estimate, we inspect all three and quote what we actually find. Sometimes the fix is insulation plus duct sealing; sometimes it's a combination. We don't sell you insulation for a problem insulation won't solve.

We install Knauf EcoFill blown fiberglass, Rockwool ComfortBatt for wall cavities and baffles, and CertainTeed TrueComfort for dense-pack applications. The brand depends on your attic's framing, your performance goals, and whether we're matching existing material. We don't push one brand for every job - we specify what we're using in the written scope, with the product data sheet, so you know exactly what goes in your attic.

Fiberglass, like Knauf EcoFill, is lighter, more affordable, and excellent for open attic floors. Rockwool is denser, fire-resistant to 2,150°F, and better for tight spaces, wall cavities, and areas where you need both insulation and sound dampening. In Campbell's Eichler-style homes and other mid-century moderns with flat roofs and limited cavity depth, Rockwool's higher R-value per inch often makes it the practical choice. We explain the tradeoffs in your written estimate and let you decide.

We use Icynene open-cell spray foam for specific applications: rim joists, kneewalls, and conditioned attic conversions where air sealing and insulation need to happen in one pass. We don't spray foam over unsealed top plates in vented attics - that's insulation before sealing, which violates our "sealed first" mission. When spray foam is the right tool, we quote it; when it's not, we tell you why.

Campbell sits in California Climate Zone 3, where current Title 24 standards call for R-38 to R-49 in vented attics for new construction and major renovations. Many existing homes in Campbell, especially pre-1990 builds in the neighborhoods off Bascom Avenue, have R-11 to R-19. We measure what you have, calculate what you need based on your energy goals, and specify the target depth in your written scope. The blower-door test at the end proves whether the assembly performs, not just whether the material is thick.

Yes. Every pro working under our name in Campbell is required to hold the license and insurance California requires for insulation and home performance contracting. We publish license numbers on the estimate page, and the crew lead carries proof of coverage on every job. This is Clause 3 of The Haven Standard: verified crews, documented and available on request.

At minimum, general liability and workers' compensation. In California, workers' comp is mandatory for crews with employees, and general liability protects your property if something goes wrong. We also carry pollution liability coverage for insulation material handling, which not every contractor maintains. Ask to see certificates - any legitimate contractor provides them without hesitation.

Permits are required in Campbell when insulation work triggers Title 24 compliance, typically during remodels, additions, or when you're claiming specific rebates. Simple attic top-ups in existing homes often don't require permits, but we check Campbell's building department requirements for every job and handle permitting when it's needed. If a contractor tells you permits are never required for insulation, that's a red flag.

We answer the phone 24/7, and we often schedule estimates within 24-48 hours in Campbell, San Jose, and Santa Clara. Same-day availability depends on current workload and whether your situation is urgent - a leaking roof with wet insulation, for example, gets prioritized over a routine efficiency upgrade. When you call (831) 534-3206, the live coordinator checks the schedule and gives you a real date, not a vague promise.

Water-saturated insulation from roof leaks, rodent infestations with active waste contamination, and failed HVAC connections in the attic that threaten equipment damage. These situations affect indoor air quality and can cause structural damage if left. We don't treat routine cold spots or high energy bills as emergencies - those get thorough estimates and scheduled work. If you're unsure whether your situation is urgent, call and describe what you're seeing.

Our phone is answered every day, and we schedule estimates and work on Saturdays when needed. Sunday work is limited to true emergencies. Most Campbell homeowners prefer weekday installations when they're at the office and the house is quiet. We text arrival windows and crew names either way, under Clause 2 of The Haven Standard.

Every job carries a written warranty on workmanship and material performance, documented in your shared folder before we leave. Manufacturer warranties on Knauf, Rockwool, CertainTeed, and Icynene products range from limited lifetime to 30 years depending on the material and application. Our workmanship warranty covers settling, coverage gaps, and air sealing failures for the period specified in your written scope. Clause 1 of The Haven Standard: it's in writing before we start.

We review the blower-door numbers together at closeout - that's your baseline proof of performance. If bills don't improve as projected, we investigate. Sometimes the issue is behavioral (thermostat settings, new equipment), sometimes it's a missed thermal bypass we can address. We don't disappear after installation. Call (831) 534-3206 and we'll schedule a follow-up to see what's happening.

Yes. Every job we do in Campbell, Los Gatos, Saratoga, Cupertino, and across our full service area follows The Haven Standard: Have it in writing, Arrive on schedule, Verified crews, Evidence on every job, No surprises. The standard was developed by the parent brand and is the agreement we work to. Your written estimate cites the specific clauses that apply to your project.

Most manufacturer warranties transfer to subsequent owners with proper documentation, which we provide in your shared folder. Our workmanship warranty terms vary by project scope - some transfer, some are original-owner only. We specify transferability in writing before work starts so there's no confusion during escrow. If you're preparing to sell, mention it when you call and we'll structure the documentation for clean handoff.
