The Topside Attic Insulation Mountain View Guarantee
We stand behind every attic we seal and insulate in Mountain View with a written promise, not a handshake. Since 2016, we’ve completed work in more than 9,000 homes, and every single job closed with a documented photo record and a written scope that both we and the homeowner signed. Our 365-Day Done Right Promise means if the insulation settles unevenly, if a sealed penetration reopens, or if the blower-door reading doesn’t hold, we come back and make it right. No dispute. No runaround. We fix it.
What’s Covered
- Workmanship on every square foot. We guarantee that insulation is installed to the R-value specified in your written scope, that air sealing is complete at all top plates and penetrations before any blown-in or batt product goes down, and that spray foam achieves full lift and coverage without voids or misses.
- Materials from name-brand suppliers. We source from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. If a batch arrives damaged or off-spec, we replace it at our cost before it touches your attic floor.
- Site condition on departure. Your crew vacuums the access path, removes all packaging and old insulation debris, and leaves the attic hatch sealed and labeled with the installed R-value and date. The Documented Photo Record we deliver shows the condition we left it in.
- On-time arrival with live communication. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. If we’re running behind due to traffic on 101 or a previous job in Los Altos ran long, we call you. No ghosting.
- Honest, locked pricing. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. The price on your signed agreement is the price you pay. We don’t “find” extra work after we’re already in your attic.
- Before-and-after verification on applicable jobs. Where air sealing is part of the scope, we publish blower-door numbers - a pressurization measurement that shows, in a single figure, how much conditioned air your home was losing before and after the work. You keep that printout.
Our Satisfaction Promise
If something’s not right, we want to hear about it. Call (669) 259-0406 and a live person answers, 24/7. No voicemail loops. Describe what you’re seeing - a cold spot in the hallway, a draft from a recessed can light we sealed, insulation that looks thin over the garage ceiling. We schedule a return visit, usually within 48 hours for Mountain View and nearby zip codes. Our technician arrives with your original written scope and the photo record from installation. We inspect, identify the gap, and fix it. The 365-Day Done Right Promise covers labor and materials for the correction. If we installed it, we stand behind it for a full year from completion. After the fix, we document again. You’ll get new photos and, on air-sealing callbacks, a fresh blower-door reading to confirm the envelope is holding. We’ve been doing this since 2016, and our callback rate stays low because we seal first, then insulate - in that order. But when a callback happens, we treat it as a chance to prove the guarantee is real.
Licensed & Insured Backing
California requires insulation contractors to carry a valid CSLB license and maintain active general liability and workers’ compensation coverage. We meet both requirements. That paperwork isn’t a formality - it’s what protects you if a technician is injured in your attic or if accidental damage occurs to your roof structure during access. We’re also insured and bonded, which means there’s a financial backstop behind our promise that goes beyond our word. Wes Okafor, our owner and lead technician, pulls permits personally when a job requires them and keeps copies on file with your project documentation. In Mountain View, where building codes are strict and inspectors know the difference between a slapped-in job and a sealed envelope, that license is what lets us stand behind our work with confidence. The guarantee only means something if the company backing it will still be here in six months. We’ve been here since 2016. We’re not going anywhere.
How to Start a Claim
Call (669) 259-0406 anytime. A live person answers. Tell them your address and the date of service. We’ll pull your file - written scope, photo record, blower-door numbers if applicable - and schedule a technician. Most callback appointments in Mountain View, Sunnyvale, and Palo Alto happen within two business days. There’s no fee for a warranty visit. If the issue falls outside the 365-Day Done Right Promise, we’ll explain why and give you a written estimate for the repair before any work begins. Haven Standard Clause 1 applies to callbacks too: flat price, written scope, your signature required.
What’s Not Covered
We don’t cover damage from homeowner alterations after we leave - if you or another contractor disturb the insulation or cut into a sealed top plate, that’s outside our scope. We don’t cover manufacturer defects in materials, though we’ll file the warranty claim with Owens Corning, Johns Manville, or whichever supplier provided the product and help you pursue a replacement. Normal settling of blown-in cellulose or fiberglass in the first 30 days is expected and accounted for in our initial depth calculation; significant settlement beyond that is covered. Rodent damage after our rodent-proofing work is covered for 90 days on the seal quality, not on subsequent infestations from new entry points we didn’t originally treat. We explain these boundaries in your written scope so there’s no confusion later.
Free Second Opinion on Any Written Estimate
If another Mountain View insulation contractor gave you a quote and the scope seems vague, bring it to us. We’ll read it with you line by line. We regularly see proposals that skip air sealing entirely, that don’t specify R-value by zone, or that promise a “package price” without itemizing materials. Under our guarantee, you get the opposite: every line item named, every product brand listed, every penetration sealed before insulation goes in. The second opinion is free, and if we find gaps in the competing scope, we’ll show you exactly what they left out.
Why We Publish Blower-Door Numbers
Most homeowners in Mountain View have never heard of a blower-door test until we mention it. It’s a pressurization reading that shows, in one number, how much air your building envelope is losing. We take that reading before we seal anything and again after air sealing and insulation are complete. The difference is your proof. A typical pre-work reading in a 1960s Eichler or ranch-style home in the Monte Loma neighborhood might show 4,500 CFM50. After proper sealing and insulation, we often see that drop to 2,200 or lower. You get both numbers in writing. No guesswork, no “trust us, it’s better.” The numbers are the guarantee.
Our Materials, Your Choice
We don’t lock you into a proprietary product. We install Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. Each brand has different strengths for Mountain View’s mild, marine climate - where summer attic temperatures rarely hit the extremes of inland California but winter moisture management matters. Your written scope names the exact product and R-value installed in each zone. If you have a brand preference, we’ll source it. If we recommend against a product for your specific application, we’ll explain why and note it in writing. The guarantee covers our installation, not the manufacturer’s chemistry, so we choose products we trust and document what we used.
Background-Checked, Uniformed Technicians
The person in your attic has passed a background check and wears a Topside uniform. You’ll know their name before they arrive. We don’t subcontract to day laborers or send crews whose training we can’t verify. That matters for guarantee enforcement - if we need to honor the 365-Day Done Right Promise, we need to know who did the original work and how they were trained. Our crews are employees, not gig workers. They know the Haven Standard because they helped write it through nine years of field practice.
Common Questions About Our Guarantee
How long does the 365-Day Done Right Promise last?
It lasts 365 days from the date of job completion, noted on your written scope. If we return to fix something within that window, the repair is covered in full. Call (669) 259-0406 to start the process - estimates for warranty work are always free.
What if I sell my house during the guarantee period?
The 365-Day Done Right Promise stays with the property, not the owner. Transfer the paperwork to the buyer and they have the same coverage. We keep digital records of every job since 2016, so we can verify coverage even if the original documents are lost.
Do you guarantee energy savings?
We guarantee the work: specified R-values, sealed penetrations, documented air-tightness improvement. Actual energy savings depend on your thermostat habits, HVAC condition, and utility rates. What we can show you is the blower-door number improving, which correlates directly with reduced conditioned air loss. Many Mountain View homeowners see lower gas bills in heating months, but we don’t promise a specific dollar amount.
Is the cleanup really guaranteed?
Yes. If we leave debris in your driveway, insulation fibers in your hallway, or a dirty attic hatch, call us. We’ll return the same day or next morning to correct it. The Documented Photo Record on Every Visit includes departure shots of the access path and work area so we can verify what condition we left.
What happens if there’s a dispute about whether something is covered?
We start with your written scope and the photo record. Those two documents define what we agreed to do and what we actually did. If the scope says we sealed all top plates and a photo shows an unsealed plate, we’re at fault and we fix it. If the scope excluded a zone and you later want it included, that’s new work with a new written price. The Haven Standard is designed to prevent disputes by documenting everything upfront.
