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.
The Hearthstone Chimney Co. Guarantee
When we say we stand behind our work in Gaithersburg, we mean it in writing. Our 90-Day Done Right Promise is not a handshake or a hope. If something we have done is not right, we come back and make it right. No paperwork to file, no argument to win, no runaround. That is the Keystone Standard, and it governs every chimney sweep, repair, and rebuild we complete in Montgomery County. We have been here since 1984, and we plan to be here thirty years from now. A company with that horizon does not cut corners on the houses it will service twice.
What’s Covered
- Workmanship on every job. The repair, sweep, or installation we perform in your Gaithersburg home is covered by our 90-Day Done Right Promise. If our workmanship fails, we return and correct it at no charge.
- 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. If a part we install proves defective, we handle the replacement.
- Jobsite cleanup. Our background-checked, uniformed technicians leave your home as clean as they found it. If we miss something, we come back and finish the job properly.
- On-time arrival. We will be there when we say. If a delay happens, we call you first. Your time in Gaithersburg matters as much as ours.
- Honest, upfront pricing. The number on your estimate is the number on your invoice. No hidden fees, no upsell ambushes, no post-job surprises. A square deal: no surprises on the bill.
Our Satisfaction Promise
If you are not satisfied with our work, we want to know. Call us at (301) 719-5236. A live person answers 24 hours a day, 7 days a week. Tell us what is wrong. We will schedule a return visit at no charge and make it right. That is the K.E.Y.S. code we operate by: Krafted right, Every time, Your home first, Standing behind it.
Most jobs are completed in a single visit, but if we need to return, we return. No arguing, no paperwork to justify the callback. Russell Haines built this company in 1984 on the belief that a chimney technician should explain like a craftsman and document like an engineer. Our Level-2 camera inspections end with photos you can see and a plain-English verdict. If that verdict missed something, or if our repair did not hold, we own it. We have served local communities for over 42 years because we do not walk away from a job until it is done right.
Licensed & Insured Backing
Our 90-Day Done Right Promise is only as solid as the company behind it. Hearthstone Chimney Co. is licensed and insured, which means our guarantee is backed by real credentials, not just good intentions. For a Gaithersburg homeowner, that matters when a technician is on your roof, inside your flue, or working with the high-tension components and combustion systems that make chimney work genuinely hazardous.
Insurance and proper licensing are the floor, not the ceiling. They protect you if something goes wrong, and they force us to maintain the training and procedures that keep things from going wrong in the first place. Our technicians are background-checked and uniformed. We do not subcontract to uninsured crews or send strangers to your door. When Russell Haines says we will be here in thirty years, the paperwork is part of that promise. A fly-by-night operation cannot say the same.
How Our Guarantee Works in Practice
Here is what the 90-Day Done Right Promise looks like for a real Gaithersburg homeowner. You book a chimney sweep and Level-2 inspection. Our technician arrives on time, in uniform, with a camera and photo report. We find a cracked flue liner and recommend a HeatShield repair. You agree to the upfront price. We complete the work. Three weeks later, you notice a draft issue you did not have before. You call (301) 719-5236. A live person picks up, even at 9 PM on a Sunday. We schedule a return visit. We find the problem, fix it, and you pay nothing additional. In writing, no arguing.
That is not a hypothetical. That is how we have operated since 1984. The K.E.Y.S. values are not wall art. They are the reason our trucks still carry the Hearthstone name in Montgomery County neighborhoods like Kentlands, Lakelands, and Old Town Gaithersburg.
What We Ask of You
A guarantee is a two-way commitment. We ask that you report concerns within the 90-day window so we can address them promptly. We ask that you allow us access to complete the correction. And we ask that you hold us to the standard we claim. If we fall short, we want to know. A company that plans to be in Gaithersburg for decades cannot afford to let small problems become silent grudges.
Standing Offers That Extend Our Commitment
Our guarantee sits alongside offers that reduce your risk before we even start. We provide a free second opinion on any written estimate you have received. We offer $50 off any repair over $250. Our seasonal tune-up is priced at $89. Seniors and veterans receive a permanent 5% discount. These are not introductory come-ons. They are standing policies, as steady as the 90-Day Done Right Promise itself.
Frequently Asked Questions
It covers our workmanship and our handling of parts. If a DuraFlex liner, HeatShield application, or Gelco cap fails due to a manufacturing defect, we will replace it. We work directly with professional-grade brands so you do not have to chase warranties yourself. Call (301) 719-5236 and we will sort it out.
Call us. A live person answers 24/7. We will ask the right questions and tell you straight whether it falls under our guarantee. If there is any gray area, we err on the side of making it right. That is what Standing behind it means in the K.E.Y.S. code.
Call (301) 719-5236. No forms to download, no portal to navigate, no callback queue. We answer the phone, we schedule the visit, we fix the problem. Most callbacks are resolved in a single visit, just like our original jobs.
The 90-Day Done Right Promise applies to the work performed for the homeowner who contracted it. If you have questions about a recent sale or purchase in Gaithersburg, call us. We will tell you what we can verify and what we can do.
We put it in writing with no arguing. We have been here since 1984. We answer our own phones. Our owner, Russell Haines, is directly involved in maintaining the standard. Many companies promise satisfaction. Fewer put a 90-day, no-argument, in-writing commitment behind every job. Fewer still can point to 42 years of local history and say we will be here to honor it.
