What Tustin Homeowners Say About Topside Attic Insulation Tustin
We’ve insulated and sealed more than 9,000 homes since 2016, and every job ends the same way: a written price delivered before we start, a documented photo record when we finish, and a homeowner who knows exactly what changed. Reviews aren’t something we chase. They’re what happens when you show up on time, seal before you insulate, and hand someone blower-door numbers that prove the work.
Recent Reviews
Our 1978 ranch in Tustin Ranch had fiberglass batting that looked like it’d been dragged around by raccoons. Wes walked the attic with me, pointed out every top plate gap and the can lights leaking conditioned air straight into the vented space. His crew air-sealed first, then blew in GreenFiber to R-49. Blower-door went from 3,800 CFM50 to 1,900. Our summer PG&E bill dropped $87 the first month.

I got three quotes for spray foam in my crawl space under the Old Town Tustin cottage. Two guys wanted to start Monday without a written scope. Wes handed me a single-page breakdown: Demilec open-cell on the rim joists, 6-mil vapor barrier on the dirt, every pier wrapped. Price didn’t change. The crew took photos of every corner before and after. Haven Standard Clause 1 is real.

My home near Hicks Canyon had radiant barrier stapled to the rafters in 2005, but half of it was hanging in strips and the attic floor was never sealed. Topside pulled the old barrier, sealed every penetration with foam, then installed new Owens Corning radiant barrier and blown-in insulation. The documented photo record showed me gaps I didn’t know I had. Attic temperature dropped 34 degrees by 2 p.m. in August.

We bought a flip near Laurelwood and the inspection said “insulation adequate.” Wes found three inches of compressed cellulose over unsealed recessed lights and a bathroom fan dumping moisture into the attic. He didn’t just quote insulation. He quoted the fix: air sealing, baffles at every soffit, new batting in the walls, and R-60 blown-in on the floor. Written price, no upsell when they found more can lights. Done Right Promise gave us confidence to proceed.

After a rodent cleanup in my North Tustin attic, I needed everything removed and replaced. Other companies wanted to blow new insulation over the old. Wes said no, Envelope doesn’t do that. They vacuumed out the contaminated material, sealed every entry point with steel mesh, sanitized, then blew in Knauf Jet Stream. Photo record included shots of the sealed gaps. I saw the proof.

I brought Wes a competitor’s quote for spray foam in my garage and living space addition near Tustin Legacy. Free Second Opinion, they said. He sat with me for twenty minutes and showed me where the other scope missed the kneewall connections and specified the wrong foam density for our climate zone. Revised the scope, beat the price by $400, and the before-and-after blower-door numbers were on my invoice. That’s not common.

Why Customers Trust Us
Every review ties back to the same few things, and that’s intentional. We seal first, then insulate. Never the reverse. We put the price in writing before anyone touches a tool, under Haven Standard Clause 1. We document every visit with photos you keep, and on air-sealing jobs, we publish before-and-after blower-door numbers so you’re not guessing whether the envelope improved.
The 365-Day Done Right Promise covers all completed work. If it’s not right, we make it right. Our materials come from eight major manufacturers, Owens Corning to Rockwool to Icynene, so we’re not pushing a proprietary product that happens to be in the warehouse. Our technicians are background-checked and uniformed, and when you call (657) 286-7673, a live person answers. No voicemail loops. No callback windows measured in business days.
We’ve been independently owned and operated under The Haven Standard since 2016. More than 9,000 homes later, the process hasn’t changed: written price, documented work, measurable results. If you’re in Tustin and want a second opinion on any written estimate, bring it to us. We’ll read it with you.
