Our Guarantee & Warranty - Hearthstone Chimney Co.

The Hearthstone Chimney Co. Guarantee

We’re Hearthstone Chimney Co., and we’ve been sweeping, repairing, and rebuilding chimneys across Cambridge and the surrounding communities for over 42 years. Our guarantee isn’t a marketing line - it’s how we’ve stayed in business since 1984. When Russell Haines started this company, he figured out quickly that a chimney company that plans to be in town thirty years from now can’t afford to cut corners today. That’s why every job we complete in Cambridge, from a routine sweep in Harvard Square to a full liner replacement in North Cambridge, is backed by our 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we come back and make it right. Period.

Call (857) 392-4709

We’ve learned something about Cambridge homeowners over four decades. You want the finding straight, the price fixed before we start, and the work done so you don’t have to think about it again. Our guarantee is built on that understanding. No surprises on the bill. No chasing us down if something’s off. We answer our own phones - a live person, 24 hours a day, 7 days a week - because guarantee means nothing if you can’t reach us when you need to. And we show up when we say we’ll show up, in uniform, with background-checked technicians who’ve been trained to treat your home like their own.

What’s Covered

• Workmanship guarantee. Every chimney sweep, repair, cap installation, liner replacement, and rebuild we perform in Cambridge is covered by our 90-Day Done Right Promise, governed by our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it. If our work doesn’t hold up, we return and fix it at no charge - no paperwork battle, no runaround.
• Professional-grade parts and materials. We work exclusively with DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes, no off-brand surprises. These are the same materials Russell Haines specifies on his own jobs, and if a part fails due to our installation, we handle the replacement under our promise.
• Complete jobsite cleanup. Our technicians lay down protective coverings, use HEPA-filtered equipment on sweeps, and leave your Cambridge home as clean as we found it - cleaner, usually. If we track soot through a hallway or leave debris behind, that’s on us to remedy.
• On-time arrival commitment. We’ll be there when we say. Our scheduling team gives you a real arrival window, and if we’re running behind, we call - no ghosting, no four-hour waits without word. Most jobs are completed in a single visit, so you’re not juggling multiple appointments.
• Honest, upfront pricing. The number on your estimate is the number on your invoice. We don’t discover “additional problems” mid-job that weren’t discussed. Our Level-2 camera inspections come with photos you can see and a plain-English verdict, documented like an engineer and explained like a craftsman, so you understand what needs doing now, what can wait, and what it will cost before we touch a tool.

Our Satisfaction Promise

Here’s what happens if you’re not satisfied with our work in Cambridge. You call us at (857) 392-4709 - and a live person answers, any hour of any day. You tell us what’s wrong. We don’t put you through a claims department or demand photos emailed to some distant office. We schedule a return visit, usually within 48 hours, and we fix the issue. No charge. No argument about whether it’s “covered.” Our 90-Day Done Right Promise is exactly that: a promise, in writing, that we stand behind.

Russell Haines has seen too many Cambridge homeowners get burned by contractors who vanish after the check clears. That’s not our model. We’re insured and bonded, state-licensed, and we’ve been at this long enough that our reputation in Cambridge matters more than any single job. If we ever fell short of that standard, word would travel fast in a city this size - and we’d deserve it. The make-it-right process is simple because we intend to honor it rarely: we train carefully, inspect our own work, and catch problems before you do. But when something slips through, we own it. That’s the Keystone Standard we’ve operated under since 1984.

Licensed & Insured Backing

Here’s the guarantee behind our guarantee. Hearthstone Chimney Co. is licensed and insured, with full coverage that protects your Cambridge property while we’re on it. This isn’t box-checking - it’s the real financial backing that makes our promises matter. If a technician accidentally damages roofing while accessing a chimney, or if an unexpected issue arises during a repair, our insurance handles it. You don’t chase us, and you don’t file with your own homeowner’s policy.

We’ve maintained this coverage without lapse for over four decades because Russell Haines knows what can go wrong in chimney work. Steep Cambridge roofs, historic masonry in neighborhoods like Mid-Cambridge and Area 4, tight flue spaces in converted triple-deckers - these conditions demand real protection, not hand-waving. Our licensing means we’ve met Massachusetts standards for chimney and fireplace work. Our insurance means if we ever failed you, there’s recourse beyond our word. Together, they’re the foundation that lets us offer our 90-Day Done Right Promise with confidence. We’ve been here since 1984. We plan to be here thirty years from now. That only works if Cambridge homeowners trust us completely.

Call (857) 392-4709 to discuss your chimney needs or to schedule a Level-2 camera inspection with photos you can see and a plain-English verdict. Estimates are free, pricing is upfront, and our live team answers around the clock.
