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 Flint Chimney Co Hempstead Guarantee
We put our name on every chimney we sweep, inspect, and repair in Hempstead. That means something specific: every repair carries a written guarantee valid for one full year from the service date, and if a covered repair fails during that year, we come back and make it right at no charge. No deductibles, no service fees, no fine print about “normal wear and tear” that magically starts the day after we leave. We’ve been doing this since 2002 as part of the Garrison Partners family of independently owned chimney companies, and the guarantee is simply how Hank Delano has always run the business. You get it in writing before we start, and it’s yours to hold us to.
What’s Covered
- Workmanship on every repair. If a repair we make fails within 365 days of the service date, we return and fix it at no charge, backed by a written guarantee you receive with your invoice.
- Written pricing before any work begins. You approve the number before a single tool comes off the truck, and the number on your final invoice is exactly what you approved.
- Cleanup after the job. We leave your hearth, floors, and surrounding area as clean as we found them. A chimney sweep shouldn’t leave a mess, and we don’t.
- Background-checked, uniformed technicians. You know exactly who is walking through your door, and they’ll be wearing a company uniform with identification.
- Professional-grade materials, specified by job. When a repair calls for new components, we use brands like DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, chosen because they hold up, not because they’re cheapest for us.
- A live person on the phone, 24/7. You get a real human being when you call, not a voicemail tree, not a callback form, not a Monday morning apology.

Our Satisfaction Promise
If something doesn’t feel right after we’ve finished, you call us. We answer. A live person picks up the phone twenty-four hours a day, seven days a week, because waiting until Monday to talk about a chimney problem is not how we operate. We’ll send a technician back to look at the issue, and if it falls under our one-year repair guarantee, we fix it at no charge. If it’s something outside the guarantee, we’ll give you a written price before any work starts, so you can decide with your eyes open. We’d rather do a second visit and keep a customer than argue about who’s responsible while smoke backs up into your living room. This is what Hank Delano built the company on, and it’s what the Garrison Code and the Garrison Standard require: do the job right, stand behind the work, and never leave a Hempstead homeowner guessing.
Licensed & Insured Backing
A guarantee is only as good as the company standing behind it. Flint Chimney Co Hempstead is licensed and insured, which means the promises we make aren’t just words on an invoice; they’re backed by a business that is accountable to New York State requirements and carries the coverage to protect your home and ours. If a technician is on your roof in Hempstead and something unexpected happens, you’re not left holding the bill. We’ve operated this way since 2002, and it’s not something we’re willing to compromise on. A chimney job involves fire, structure, and air safety, and those are not areas where shortcuts belong. When you hire us, you’re hiring a company that carries the proper licensing and insurance to do the work responsibly.

AfterWhat the Guarantee Does Not Cover
Let’s be straight about this, because honest guarantees are the only kind worth having. Our one-year written guarantee covers the workmanship and materials we install. It does not cover pre-existing conditions we documented during your inspection that you chose to defer, damage caused by chimney fires, extreme weather events that alter the structure, or routine maintenance like sweeping after we leave. If you had questions about whether something was covered, our technicians explain the scope in plain language before work begins, so you’re never surprised later. That explanation is part of the written price, part of the job, and part of how we’ve earned our reputation in Hempstead.
Why We Put It in Writing
Most chimney companies in Hempstead will shake your hand and tell you not to worry. We’d rather hand you a document. The 365-Day Done Right Promise isn’t a slogan; it’s the actual terms we operate under, printed and included with every repair. If a covered repair fails within twelve months, we return at no charge. That’s it. We don’t ask you to prove it wasn’t your fault. We don’t prorate the value based on how many weeks passed. We come back, we fix it, we leave. Hank Delano has owned this company since day one, and he’s not interested in building a business on fine-print exceptions. The written guarantee exists because trust is earned one repaired chimney at a time, and in Hempstead, word travels fast.
How to Make a Guarantee Claim
Call (516) 559-6922. Tell the live person who answers what’s going on. We’ll schedule a return visit, our technician will assess the issue against the written guarantee you received, and if it’s covered, we fix it on the spot. No forms to mail, no third-party claims process, no sitting on hold with a warranty department in another state. You call the same number you called to book the original job, and the same company shows up. Simple. That’s how a guarantee should work, and in Hempstead, that’s how ours does.
