Mention this offer when you call (408) 837-7384.
Free Second Opinion on Any Written Estimate
Got a quote from another San Jose insulation company that feels high or vague? Bring it to us. Walt Brenner, our owner, will walk your attic personally and give you a straight read on whether that estimate is fair, inflated, or missing something important. If we can do the job better for less, we’ll tell you. If the other guy’s quote is actually decent, we’ll tell you that too. That’s how a neighbor operates. Valid through December 31, 2026. Mention this offer when you call (408) 837-7384.
No Trip Charge Inside Santa Clara County
We don’t charge a fee just to show up and look at your attic, crawl space, or walls. You’ll get a real evaluation of your insulation situation, and you’ll get it without paying a dime for the visit. That includes homes in Willow Glen, Almaden Valley, Evergreen, Berryessa, and everywhere else in our service county. The assessment is the same thorough one whether you hire us or not. Valid through December 31, 2026. Mention this offer when you call (408) 837-7384.
10% Off for Seniors and Veterans, Always
This one never expires. If you’re 65 or older, or if you’ve served in the military, you get 10% off every service we offer, from blown-in attic insulation to crawl space encapsulation. We’ve been doing this since the day we opened in 2000, and we’re not about to change it. It stacks with our free second opinion offer and our no trip charge policy. You earned it, so call (408) 837-7384 and mention it when you book.
Free Home Energy Audit with Any Insulation Project
When you hire us for attic insulation, wall insulation, or spray foam, we’ll include a full home energy audit at no charge. That’s a diagnostic walkthrough of your home’s thermal envelope, including a look at air leaks, duct conditions, and any spots where your conditioned air is escaping. You’ll get a clear picture of what’s costing you money, not a sales speech. It’s our way of making sure you’re paying for the right fix, not just a fix. Valid through December 31, 2026. Mention this offer when you call (408) 837-7384.
