Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterThe Hearthstone Chimney Co. Guarantee
When we say we stand behind our work in Waltham, we mean you’ll never need to chase us down or argue about whether something was done right. Our 90-Day Done Right Promise is simple: if it’s not right, we come back and make it right. In writing, no arguing. We’ve been serving local communities for over 42 years, and a company that plans to be in Waltham thirty years from now doesn’t cut corners on the jobs it guarantees today. Every chimney sweep, repair, liner installation, and cap replacement we complete in Middlesex County carries this promise because our reputation here is worth more than any single invoice.
What’s Covered
- Workmanship on every job. Whether we’re rebuilding a chimney crown on a Colonial near Moody Street or installing a DuraFlex liner in a ranch off Trapelo Road, the labor and installation quality are covered by our Done Right Promise for 90 days.
- Professional-grade parts and materials. We work exclusively with DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes slipped past you. If a part fails due to our installation, we handle it.
- Complete jobsite cleanup. Our background-checked, uniformed technicians leave your Waltham home as clean as they found it. If we miss something, we’ll return to finish the cleanup properly.
- On-time arrival as promised. We’ll be there when we say. If a delay happens due to our scheduling, we communicate it promptly and work to minimize your inconvenience.
- Honest, upfront pricing. The number on your estimate is the number on your invoice. No surprises, no hidden charges, no “we found something else” add-ons after work begins without your clear approval.
Our Satisfaction Promise
If you’re not satisfied with our work in Waltham, here’s exactly what happens. Call us at (781) 905-8338 - a live person answers 24 hours a day, 7 days a week. Describe what isn’t right. We’ll schedule a return visit, typically within 48 hours for non-emergency issues and same-day if there’s a safety concern. Our technician arrives, assesses the problem, and fixes it. No paperwork battle, no “let us check with the office,” no pro-rated refund games. The Keystone Standard governs everything we do: Krafted right, Every time, Your home first, Standing behind it. Russell Haines built this company in 1984 on the principle that a handshake in Waltham should still mean something, and we’ve never abandoned that. Most jobs are completed in a single visit the first time, but when something goes wrong, we don’t disappear. We’ve been here for over four decades, and we intend to be here when you need us again.
Licensed & Insured Backing
Paper promises mean little without real backing. Hearthstone Chimney Co. is licensed and insured, which means if the unexpected happens - property damage, technician injury, or a code compliance issue - you’re not left holding the bag. In Waltham, where homes range from 19th-century Victorians near the Charles River to mid-century builds in the Cedarwood area, chimney work carries real risks: roof access, structural weight, carbon monoxide pathways. Our insurance and bonding exist so you never have to wonder who pays if something goes wrong. We carry this coverage not as a selling point, but as the minimum standard for professionals who enter your home and work on systems that affect your family’s safety. Combined with our 90-Day Done Right Promise, it means you’re protected on every front - the quality of the work, the integrity of the people doing it, and the financial backing behind both.
How Our Guarantee Compares to Typical Chimney Warranties
Most Waltham homeowners have encountered chimney companies that offer vague “satisfaction guaranteed” language without specifics. Here’s what we actually commit to versus what you often see:
| What Others Typically Offer | Hearthstone Chimney Co. Promise |
|---|---|
| Verbal assurance, no written terms | 90-Day Done Right Promise in writing, no arguing |
| Call-back queues or voicemail systems | Live person answers every call, 24/7 |
| Unclear parts coverage, generic materials | Professional-grade brands specified by name: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, Copperfield |
| Estimate surprises on final invoice | No-hassle upfront pricing - estimate matches invoice |
| Technicians of unknown background | Background-checked, uniformed technicians |
| Multiple visits for single job | Most jobs completed in a single visit |
What Homeowners Should Know About Manufacturer Warranties
The brands we install - DuraFlex stainless steel liners, HeatShield cerfractory flue resurfacing, Gelco chimney caps - carry their own manufacturer warranties against material defects. These are separate from our workmanship guarantee. Our role is to install these products correctly so those manufacturer warranties remain valid. Improper installation voids most manufacturer coverage, which is why our Done Right Promise matters beyond the 90-day window. When we install a DuraFlex liner in a Waltham home near Beaver Brook Reservation, the manufacturer’s material warranty runs for years, but only if the installation met their specifications. We document our work with Level-2 camera inspections, photos you can see, and a plain-English verdict - documented like an engineer, explained like a craftsman. That documentation protects both warranties: ours on the labor, and the manufacturer’s on the materials.
Standing Offers That Work With Our Guarantee
Our guarantee isn’t a standalone promise - it pairs with offers we’ve maintained consistently:
- $50 off any repair over $250 - applied upfront, no games.
- Free second opinion on any written estimate you’ve received from another Waltham chimney company.
- $89 seasonal tune-up - a flat price, not a bait-and-switch.
- Permanent 5% senior and veteran discount - no expiration, no restrictions beyond proof of status.
These aren’t “introductory” rates designed to hook you before the real bill arrives. A square deal: no surprises on the bill. That’s how we’ve operated since 1984.
Frequently Asked Questions About Our Guarantee
Call us anyway at (781) 905-8338. While our written Done Right Promise covers 90 days, we’ve been in Waltham long enough that many issues trace to something we can help with, and we’ll be straight with you about whether it’s on us or simply time and weather taking their toll. For manufacturer defects on parts we installed, the brand’s warranty may apply regardless of timing.
No - that’s what homeowner’s insurance is for. Our guarantee covers our workmanship and the proper function of what we installed. A lightning strike or ice dam tearing off your chimney cap in a Waltham winter isn’t a workmanship issue, though we’re happy to assess the damage and give you an honest repair estimate.
We call you before you’re waiting. If we miss our window due to our own scheduling, we don’t pretend it didn’t happen. You’ll know the revised time, and if the delay is significant, we’ll discuss rescheduling options that work for your calendar.
Absolutely. Every estimate we provide includes the Done Right Promise terms. No fine print, no “see website for details.” Russell Haines has always believed that if you need a lawyer to understand your chimney sweep’s guarantee, the guarantee is probably worthless.
We keep our own records, but holding onto your estimate and invoice speeds things up. The 90-Day Done Right Promise is designed to need “no paperwork and no arguing” - we know our customers, we know our jobs, and we don’t make you reconstruct a file folder to get help.
