Contact Topside Attic Insulation Union City - Free Insulation Estimate in Union City
Call (650) 381-1512 and a live coordinator will pick up, day or night. There’s no hard sell, no script to sit through, just a quick conversation to understand what you’re dealing with - hot second floor, cold rooms, high PG&E bills, whatever it is. We’ll schedule a free attic assessment, often same day if you’re in Union City, and you’ll have a written estimate with real numbers before we leave.
What Happens When You Call
Step 1: We answer. A live coordinator takes your call at (650) 381-1512, 24 hours a day. They’ll ask what’s going on - temperature complaints, energy bills, a home inspection finding - and find a time that works.
Step 2: We assess your attic. A technician arrives in the scheduled window, texts when they’re on the way, and climbs up to document what they find. They photograph the condition, measure existing insulation depth, and run a blower-door test if needed to locate air leaks.
Step 3: You get a written estimate. Before anyone touches a tool, you receive a flat price, a written scope of work, and the warranty terms. This is Clause 1 of the Haven Standard - have it in writing. No verbal quotes, no “we’ll figure it out as we go.”
Step 4: We complete the work and prove it. The crew seals first, then insulates, in that order. You get before-and-after photos, blower-door numbers showing the actual improvement, and a documented record of what was done. That’s Clause 4 - evidence on every job.
Why Union City Homeowners Call Us First

- Union City response time that respects your schedule. We’re based right here in Union City, not dispatching from across the Bay, so we can usually assess your attic same day or next day. No four-hour windows where you’re stuck waiting.
- Every pro is required to carry the license and insurance California demands. We verify it before they work under our name, and the license number appears on your paperwork. You’re not guessing who’s in your attic.
- Flat pricing, written scope, no door upsell. The estimate you sign is the price you pay. Clause 5 of the Haven Standard - no surprises. We don’t “find” extra work once we’re up there and pressure you into it.
- The work is warrantied and documented. You get photos of what we found, readings of what we improved, and a written warranty you can reference later. If something’s not right, we have a record to fix it.

Frequently Asked Questions - Booking & Estimates

Yes. The attic assessment and written estimate cost nothing, and you’re not obligated to book. We believe you should see the actual condition of your attic and understand the price before deciding. Call (650) 381-1512 to schedule - estimates are free.
Same day or next day for most Union City calls, depending on when you contact us. Nearby cities like Newark and Fremont typically fit into the same schedule. Call (650) 381-1512 and the coordinator will give you the next available window.
No. Our phone is answered 24 hours a day, every day of the week, and we do not add surcharges for weekend or evening appointments. The flat price in your written estimate is what you pay, regardless of when we do the work.
Your address, a brief description of the problem - hot rooms, cold drafts, high bills, a home inspection note - and any recent energy bills if you want to discuss savings. You don’t need to climb into the attic or take measurements. We’ll handle that during the assessment.
We accept major credit cards, checks, and financing options for larger jobs. Payment terms are spelled out in your written estimate before work begins, so there’s no confusion. Call (650) 381-1512 if you have specific questions about financing.
