Our Guarantee & Warranty - Hearthstone Chimney Co.

The Hearthstone Chimney Co. Guarantee

When we say we stand behind our work, we mean it in writing. Our 90-Day Done Right Promise means if something isn’t right after we’ve finished, we come back and make it right. No paperwork to dig up, no argument about whose fault it was, no runaround. We’ve been serving Queens and the surrounding communities for over 42 years, and we plan to be here for another thirty. A company with that horizon doesn’t cut corners on the work we put our name on. Every chimney sweep, every liner installation, every crown rebuild in Bayside or Astoria or Forest Hills carries the same backing: done right, and we stand behind it.

What’s Covered

• Workmanship on every job. Whether we’re running a Level-2 camera inspection, installing a DuraFlex liner, or rebuilding a chimney crown with HeatShield, the labor is covered by our written promise. If our work doesn’t hold up, we fix it.
• Professional-grade parts and materials. We use DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield products exclusively. No builder-grade substitutes, no off-brand surprises. If a part we install fails because of our handling, that’s on us.
• Cleanup that leaves no trace. Our technicians lay protective coverings, work with dust containment in mind, and vacuum before they leave. If we miss something, we’ll come back and finish the job properly.
• On-time arrival, or we tell you why. We’ll be there when we say. If traffic on the Long Island Expressway or a previous job runs long, our office calls you with a real ETA, not silence.
• Honest pricing with no surprises. The number on your estimate is the number on your invoice. We don’t tack on charges after the fact because we “found something else.” If additional work is needed, we discuss it and you approve it before we proceed.

Our Satisfaction Promise

If you’re not satisfied with our work, you call us. A live person answers the phone 24 hours a day, 7 days a week. We schedule a return visit at your convenience, review what happened, and fix it. The 90-Day Done Right Promise is governed by our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it. There’s no fine print that voids it, no hoops to jump through. We’ve honored this promise since 1984 because it’s simpler than making excuses, and it keeps our customers calling us back. Most issues are resolved in a single visit by the same background-checked, uniformed technician who did the original work. If the fix requires different expertise, we send the right person. You don’t pay twice for our mistake.

Licensed & Insured Backing

Our written guarantee is only as solid as the company behind it. Hearthstone Chimney Co. is licensed and insured, which means if the unexpected happens, there’s real coverage in place. For a Queens homeowner, that’s protection against liability if a technician is injured on your property, and it’s recourse if damage occurs during work. We’ve maintained these credentials continuously since 1984. Insurance and bonding aren’t marketing points for us. They’re the floor beneath everything else we promise. A handshake guarantee from an uninsured operator isn’t worth the risk in a borough where a single incident can turn into a five-figure problem. We carry the coverage so you don’t have to worry about it.

How Our Guarantee Compares to Typical Chimney Service Warranties

Most chimney companies in Queens offer some form of warranty, but the details matter. A “lifetime” guarantee on a liner often means the manufacturer’s warranty, which covers defects in the material, not the installation. If the liner pulls away from the top because it wasn’t secured properly, the manufacturer won’t help you. We’ve seen this in homes from Jamaica Estates to Sunnyside. Our 90-Day Done Right Promise covers the workmanship, not just the part. We also don’t require you to pay for an annual “warranty inspection” to keep coverage active. Some competitors use that model to lock in recurring revenue. Our guarantee stands on its own because we trust our work to hold up.

What Homeowners Should Ask Any Chimney Contractor

Before you hire anyone to work on your chimney, ask these questions. The answers separate a real guarantee from a sales line.

• Is the guarantee in writing? Verbal promises evaporate. We put ours on paper every time.
• Who handles the claim? With us, you call the same office that scheduled the job. No third-party administrator, no 800-number maze.
• What voids the coverage? Our promise has no hidden void clauses. If we did the work and it’s not right, we fix it.
• Is the company licensed and insured? Ask for proof. We carry both, and we’ve never had a lapse in 42 years of operation.

Our Standing Offers

These aren’t limited-time promotions. They’re permanent commitments to fair dealing.

• $50 off any repair over $250. Applies to chimney repair, fireplace services, chimney cap and crown work, and chimney liner and rebuild projects.
• Free second opinion on any written estimate. Bring us another company’s quote. We’ll inspect and give you our assessment with no pressure to hire us.
• $89 seasonal tune-up. A full sweep and basic inspection to keep your system running safely before burning season.
• 5% senior and veteran discount. Permanent, no expiration, no complicated verification process.

What Happens If You Need to Make a Claim

Call (516) 531-6315. A live person answers, 24 hours a day, 7 days a week. We pull your job record, including the photos from your Level-2 camera inspection and the plain-English verdict our technician provided. If the issue is related to our work, we schedule a return visit. Most claims are resolved in a single trip. If the problem stems from something outside our scope, we’ll explain exactly what we found and why, with documentation you can use with another contractor if needed. No ghosting, no deflection. That’s the Keystone Standard.

Why We Can Offer This Guarantee

We’ve completed most chimney jobs in a single visit for 42 years because our technicians are trained on professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. They arrive in uniform, background-checked, with the right tools and parts already on the truck. We don’t send someone to diagnose and then schedule a second crew to fix. That efficiency means fewer callbacks, and fewer callbacks mean we can afford to stand behind our work without hedging. In Queens, where winter comes hard off the Atlantic and salt air eats at masonry year-round, chimneys take a beating. We’ve seen what fails and why, and we build to last.
