The Walt’s Insulation Guarantee
We’ve been insulating homes across Sunnyvale and the surrounding South Bay since 2000, and we’ve never once expected a homeowner to take our word on faith. That’s why every job we do is backed by the Done Right Promise: if it’s not done right, we make it right. No runaround, no fine print, no arguing about who caused what. Walt Brenner runs this company as an owner-operator, which means the person who stands behind the guarantee is the same person whose name is on the truck. If something isn’t right after we leave, you call us, and we come back. That’s the whole promise. It has been for over 25 years.
What’s Covered
- Workmanship for life. Every installation we perform is covered by the Done Right Promise for as long as you own the home.
- Manufacturer-backed materials. We install insulation from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the products themselves carry their own manufacturer coverage in addition to our workmanship guarantee.
- Clean job sites, every time. We protect your floors, haul away old insulation and debris, and leave your attic or crawl space cleaner than we found it.
- On-time arrival. If we say we’ll be there at 8:00, we’re there at 7:55. Background-checked, uniformed technicians on every visit, so you know exactly who’s walking into your house.
- Upfront, honest pricing. The price we quote is the price you pay. No surprise add-ons, no “while we’re here” upselling, no vague line items.
- Second opinions on us. If you’ve got a written estimate from another company, we’ll give you a free second opinion on it. No obligation, just straight answers about whether it’s fair.
- Standing discounts, no fine print. Seniors and veterans get 10% off, always. Repairs over $200 get $40 off. These aren’t seasonal promotions; they’re permanent.
- No trip charge in our service county. If we’re coming out to take a look, we don’t charge you just for showing up.
Our Satisfaction Promise
Here’s what “make it right” actually looks like in practice. Say we blow in attic insulation and a week later you notice a corner of the attic wasn’t filled to the depth we agreed on. You call (669) 215-4805, a live person answers, and we schedule a return visit. Walt Brenner or one of his senior technicians comes out, checks the work, and fixes it. You don’t pay for the callback. You don’t pay for the additional material. You don’t get bounced between a call center and a subcontractor, because we don’t use either one. The Done Right Promise isn’t a warranty certificate that lives in a drawer; it’s a standing instruction to every technician who works under this roof. If a homeowner isn’t satisfied with how the job turned out, we keep working until they are. That’s been the policy since 2000, and it’s why much of our work in Sunnyvale comes from referrals and repeat customers who’ve seen us honor it.
Licensed & Insured Backing
A guarantee is only as good as the company standing behind it, and you can verify who you’re dealing with before you ever sign a contract. Walt’s Insulation is licensed and insured, with a published address in the service area and a license number you can look up. We’re locally owned and owner-operated, not a franchise and not an 800 number that routes to a call center somewhere else. When you hire us, you’re hiring a company with real standing in the community: a physical location, a state license, insurance coverage, and an owner whose name and reputation are attached to every job. That’s the difference between a paper promise and a guarantee you can actually collect on. If you’d like to see our license or insurance documentation before making a decision, call (669) 215-4805 and ask. A live person will help you, any hour of the day or night.
