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 isn’t a handshake or a vague feeling of goodwill. It’s a signed commitment: if something we did isn’t right, we come back and make it right. No paperwork to dig up, no arguing about whose fault it was, no runaround. We’ve been serving Northport and the surrounding communities for over 42 years, and we plan to be here for another thirty. A company with that horizon doesn’t burn bridges over a callback. Every job we complete in Northport, from a routine chimney sweep on Laurel Road to a full liner replacement near Steers Pit, carries this guarantee because our reputation is built on what happens after the invoice is paid, not before.

What’s Covered

• Workmanship that lasts. Our technicians are trained on professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, and we install them to manufacturer spec. If our installation or repair fails due to how we did the work within 90 days, we fix it at no charge.
• Parts handled properly. We don’t substitute builder-grade materials to pad a margin. The brands we use are the brands we quote. If a part we supplied proves defective in that same window, we handle the replacement and the labor to install it.
• Cleanup that’s complete. Chimney work is messy by nature, but your home shouldn’t show it. We lay protective coverings, use HEPA-filtered vacuums, and leave the work area as we found it. If we missed something, you call us and we return to finish the job properly.
• On-time arrival, as promised. We’ll be there when we say. If our schedule shifts due to weather or an emergency call ahead of you, we notify you directly. No ghosting, no four-hour windows that stretch to six without a call.
• Honest pricing from the start. The number on your estimate is the number on your invoice. We don’t discover “surprise” problems mid-job that weren’t visible during inspection. Our Level-2 camera inspections catch issues before we quote, so you know what you’re paying for before we start.

Our Satisfaction Promise

Here’s what happens if you’re not satisfied. You call (631) 528-2501, and a live person answers, 24 hours a day, 7 days a week. You explain what’s wrong. We schedule a return visit, typically within 48 hours for non-emergency issues and same-day if there’s a safety concern. Our technician arrives in uniform, reviews the original work, and fixes what’s needed. If we disagree on whether something’s wrong, we default to your judgment. The K.E.Y.S. values code governs this: Krafted right, Every time, Your home first, Standing behind it. We’ve honored this dozens of times over four decades in Northport. Not because we’re perfect, but because we believe a guarantee you have to fight to use isn’t a guarantee at all. The 90-Day Done Right Promise is in writing, no arguing. That’s the Keystone Standard, and it’s how we’ve operated since 1984.

Licensed & Insured Backing

Any chimney company can print a guarantee. The real protection sits behind it: proper licensing and insurance that actually pays out if something goes wrong. We’re licensed and insured, which means our work meets New York State and Suffolk County requirements, and our coverage protects your property if the unexpected happens. In Northport, where many homes date to the early 1900s and chimney systems can hide surprises behind original brickwork, this matters. Our insurance and bonding aren’t abstract concepts. They’re the financial backing that makes our written promise collectible. Combined with background-checked, uniformed technicians and 42 years of local accountability, you know who’s standing behind the signature. Done right, and we stand behind it. That’s not a slogan. It’s the only way we’ve ever done business.

How Our Guarantee Compares

We’ve seen the fine print other companies use. “Satisfaction guaranteed” with no definition of satisfaction. “Workmanship warranties” that require you to prove the failure wasn’t caused by “normal wear,” a loophole wide enough to drive a truck through. Or guarantees that expire before the first heating season ends.

Our 90-Day Done Right Promise is different by design. The 90-day window covers you through your first real burn cycle in Northport, when any installation issue will show itself. The “no arguing” clause means we don’t deploy a claims department to wear you down. And the “in writing” requirement means both sides know exactly what was promised before any work begins.

We also offer standing protections beyond the base guarantee: $50 off any repair over $250, a free second opinion on any written estimate you bring us, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount. These aren’t introductory come-ons. They’re permanent fixtures because we want long-term relationships, not one-time transactions.

What Homeowners Ask About Our Guarantee

Does the 90-Day Done Right Promise cover manufacturer defects?

It covers our installation and the parts we supply. If a DuraFlex liner or HeatShield product fails due to a manufacturing flaw, we handle the replacement and reinstall under our promise, then pursue the manufacturer separately. You deal with us, not a warranty hotline.

What if I find a problem on day 91?

Call us anyway. The 90-Day Done Right Promise is our formal commitment, but we’ve made good on issues outside that window when the circumstances warrant it. A company that’s been in Northport since 1984 doesn’t measure every relationship by a calendar.

Do I need to keep paperwork to make a claim?

No. We keep records of every job. If you don’t have your copy, we have ours. The “no arguing” part of our promise includes not making you hunt through filing cabinets to prove we were there.

Is the guarantee transferable if I sell my home?

Our guarantee applies to the work performed at the specific property and can be transferred to a new owner with written notice. This matters in Northport’s active real estate market, where chimney condition often comes up during inspection.

How do I start a claim if something’s wrong?

Call (631) 528-2501 any time, day or night. A live person will take your information and schedule a technician to assess the issue. Most callback visits are completed in a single trip, just like our original jobs.
