Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
The Hadley Chimney West Covina Guarantee
Here’s the short version: we stand behind the work we do in West Covina with a 365-Day Done Right Promise. That means every sweep, every repair, every gas fireplace service call comes with a written guarantee before we leave your driveway. If something isn’t right, we come back and make it right. No fine print that evaporates when you call. No “that’s normal wear” conversation. We’ve been doing this since 2003, and Cory Mitchell still answers for the work personally. A clean sweep with photos to prove it isn’t a tagline. It’s how we document what we did, what we found, and what it looked like when we finished.
What’s Covered
- Workmanship on every repair – If a repair we make fails within 365 days, we return and fix it at no charge. That’s a written guarantee, not a handshake.
- Parts handling on everything we install – We work with DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield because these are materials built to last. You won’t find whatever was cheapest on the truck going into your chimney.
- Cleanup after every job – When we sweep a chimney in West Covina, we cover the work area, vacuum as we go, and leave your home the way we found it. Soot belongs in the chimney, not on your mantle.
- On-time arrival with live tracking – Through The Relay Visibility Guarantee, you get a tracked arrival window and live updates. You know exactly who is coming and when, not a four-hour guess.
- Honest pricing before work starts – You get a written price before we touch anything. No surprise charges at the door, no “while we’re here we noticed” additions that double the bill.
- Before-and-after photo documentation – Every job includes photos of what we found and what we fixed. You get proof, not a story.

Our Satisfaction Promise
If something about the work doesn’t sit right, call us. A live person answers at (661) 402-9036, day or night. We’ll talk through what’s bothering you, schedule a return visit, and Cory Mitchell will personally review what happened. If a repair failed, the second visit is free. That’s the 365-Day Done Right Promise in action: it’s not an upsell, it’s the standing rule for every job we do in West Covina. We don’t ask you to prove anything beyond what the photos already show. We’d rather spend the time and gas to come back than leave you wondering if your chimney is safe. That’s how we’ve kept the business running since 2003, one honest conversation at a time.

AfterHow the Guarantee Works in Practice
Here’s what happens when you book with Hadley Chimney West Covina. You call (661) 402-9036 and a live person picks up. We schedule a time. You get a tracked arrival window through The Relay Visibility Guarantee, so you’re not waiting around all day. The technician arrives in uniform, walks the chimney setup with you, and gives you a written price before any work starts. If the price makes sense, we do the job. When we’re done, you get before-and-after photos and a digital invoice. And if anything we repaired fails within 365 days, you call us and we come back. Free. That’s the whole system. No mystery, no pressure, no surprises.
Why We Put This in Writing
Most chimney companies in West Covina will tell you they do good work. Very few will put a 365-day promise on paper and hand it to you with the invoice. We do it because we work on things that can burn your house down if they’re done wrong. Creosote, the flammable tar buildup that makes chimneys a fire risk, doesn’t care about good intentions. A cracked flue liner doesn’t fix itself because someone was polite. You need real work, done correctly, standing behind a real guarantee. We put it in writing because we’ve been doing this long enough to know that trust is earned one documented job at a time. Cory Mitchell started this company in 2003, and every repair still carries his name on the line.
