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.

AfterChimney Cleaning Specials in Gaithersburg, MD
Call (301) 719-5236 and a live person will pick up, day or night. We run these offers year-round because Gaithersburg homeowners deserve to know what a chimney sweep costs before we ring the doorbell. No bait-and-switch, no hidden fees. The price we quote is the price on the invoice. We’ve been sweeping chimneys here since 1984, and we plan to be here thirty more years. That only works if people trust the deal.
Current Offers
$50 Off Any Repair Over $250
If your Level-2 camera inspection turns up cracked flue tiles, a damaged crown, or a liner that’s seen better days, we’ll take $50 off the repair bill. This applies to any single repair or combined repair work totaling more than $250. Valid through December 31, 2026. Mention this offer when you call (301) 719-5236.
Free Second Opinion on Any Written Estimate
Another company handed you a quote for liner replacement or a full rebuild and you’re not sure it’s right? Bring us their written estimate and we’ll do our own camera inspection, show you the photos, and give you our plain-English verdict. No charge for the second look, even if you decide to stay with the other guy. Valid through December 31, 2026. Mention this offer when you call (301) 719-5236.
$89 Seasonal Tune-Up
Our seasonal tune-up covers a full chimney sweep, exterior visual inspection, and damper check to make sure you’re ready for burning season in Montgomery County. We’ll catch the small stuff before it turns into an emergency call in January when it’s twelve degrees in Kentlands. Valid through December 31, 2026. Mention this offer when you call (301) 719-5236.
Permanent 5% Senior and Veteran Discount
This isn’t a flash sale. If you’re 65 or older, or if you’ve served in the armed forces, you get 5% off every service, every time you call. We apply it automatically once you’re in our system, so you never have to remember to ask. Valid through December 31, 2026. Mention this offer when you call (301) 719-5236.
How to Redeem
Step one: call (301) 719-5236 and tell the live person who answers which offer you saw. Step two: book your visit at a time that works, and we’ll confirm with a call ahead. Step three: mention the offer again when our uniformed technician arrives. We’ll apply it before you pay. No paperwork to mail in, no codes to forget.
What These Offers Actually Cover
Our $89 seasonal tune-up includes the sweep itself, a visual inspection of the exterior masonry and cap, and a damper function check. If we find something that needs repair, we’ll show you the camera footage and explain whether it’s urgent or can wait. The $50 repair discount applies to crown rebuilds, liner work with DuraFlex or HeatShield, cap replacements with Gelco or Famco, and masonry repairs using Olympia Chimney or Copperfield materials. The second opinion is exactly what it sounds like: we look at what they said, we look at your chimney, and we tell you what we see. Sometimes it matches. Sometimes it doesn’t.
We don’t upsell liners to people who don’t need them. We don’t invent cracks that aren’t there. The photos from our Level-2 inspection are yours to keep, and our technician will explain what you’re looking at without the jargon. Done right, and we stand behind it.
Why We Don’t Do “Limited Time” Pressure
These offers run through December 31, 2026, and we’ll probably renew them after that. We’re not trying to scare you into calling today with fake countdown timers. Chimney maintenance in Gaithersburg is seasonal, not desperate. The real risk is skipping the sweep because you think it’ll cost too much, then finding out in February that a blocked flue has been venting carbon monoxide into your bedroom. Or that a cracked liner has been sending sparks into your wall cavity every time you light a fire. We’d rather you call when you’re ready, know what you’ll pay, and get the work done by someone who’ll still be here if something goes wrong.
Our 90-Day Done Right Promise covers every job. In writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it. Russell Haines put that in place when he founded the company in 1984, and it’s still how we operate in Gaithersburg, North Potomac, Derwood, and the rest of Montgomery County.
FAQ
No, we apply one discount per job, whichever saves you more. For most repair work over $250, the $50 off is the better deal. For smaller jobs, the 5% senior or veteran discount may help. We’ll calculate both and give you the lower price. Call (301) 719-5236 and we’ll run the numbers before you book.
The seasonal tune-up includes a standard sweep and visual inspection. If we see signs of damage or you want the full camera inspection for peace of mind, we can add a Level-2 inspection during the same visit. We’ll quote the additional cost upfront, and you’ll get the photos and written report same day. Call (301) 719-5236 to ask about bundling.
Calls are answered by a live person 24 hours a day, 7 days a week. If you have a chimney fire, severe leak, or carbon monoxide concern, we’ll get someone out. Emergency rates may apply for after-hours dispatch, but we’ll tell you that on the phone before we send a technician. No surprises on the bill. Call (301) 719-5236 any time.
