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.

AfterFast, Reliable Chimney Repair Across Exton
Chimney repair in Exton usually falls into two buckets on the homes we see: masonry work on the exterior stack, and flue liner or cap problems on the inside. Most Exton repair calls we run are for cracked crowns, spalled brick, and mortar joints that have opened up after years of freeze-thaw cycles, not for interior flue failures. We price every repair in writing before we book the truck, and the number you approve is the number on the invoice. Call (830) 251-4560 and you’ll get a live person, not a voicemail tree, any hour of the day.
Why Flint Chimney Sweep Is Exton’s Preferred Chimney Repair Company
Exton homeowners have a particular frustration with chimney companies: the tech shows up, pokes around for twenty minutes, then hands over a quote with a comma in it and a vague warning about “safety.” That’s not how we operate. Every Flint Chimney Sweep repair in Exton gets a written price before work begins, and that written price includes our 365-Day Done Right Promise: if a covered repair fails within one full year, we return at no charge. No argument, no re-quote, no “that’s a different problem.”
Our technicians are background-checked and uniformed, so when the truck pulls up to a house off Route 100 or near the Exton Square Mall, you know exactly who’s walking through the door. We coordinate dispatch from our Philadelphia office, but crews serve Exton locally, and we’ve worked on enough Chester County masonry chimneys to know what the weather does to them. The repair call off Waterloo Boulevard is a good example: crumbling crown, spalled top course, water in the smoke chamber. We rebuilt the crown, repointed the brick, set a new stainless cap, and ran a camera through the flue to confirm the liner was dry before we called it done.
Chimney Masonry Repair in Exton
Chimney masonry repair in Exton is the work we do most often, because Exton sits in a band of Chester County where exterior masonry chimneys take the full brunt of freeze-thaw cycles off the Route 100 corridor. Water gets into the brick, freezes, expands, and pops the face off the brick over time. That’s spalling. The crown (the concrete cap on top) cracks first, then the mortar joints open, and the whole top section of the stack starts moving. In this climate, a chimney that’s never been repointed after 25 years is usually past due.
What you’ll pay depends on how far the damage has traveled, but here are real Exton market ranges: mortar repointing on a standard two-story exterior chimney runs $600 to $1,400, depending on how many courses are failing. A chimney crown rebuild with proper crown-coat material runs $800 to $1,800. Spalling brick repair, where we cut out and replace individual face brick, runs $400 to $1,200. Full chimney rebuilding above the roofline starts around $2,800 and can run past $6,000 if the damage extends below the flashing line. Every one of these gets a written price before we start.
Mortar Repointing and Tuckpointing
Repointing means cutting out the crumbling mortar between bricks and packing in fresh mortar that matches the original in color and strength. Tuckpointing is the fine detail work: two-tone mortar lines that make the repaired joints blend with the original brickwork. We do both on Exton chimneys, and we match the mortar, not paint over it.
Spalling Brick Repair and Chimney Rebuilding
When the face of a brick pops off, water has already found its way in. If you catch it early, we replace the individual brick and repoint around it. If the spalling goes deep, the top courses need to come down and go back up. We’ll tell you which it is, with photos, before you pay for anything.
Chimney Cap Installation in Exton
Chimney cap installation in Exton is the single cheapest repair you can do that prevents the expensive ones. A proper stainless cap keeps rain out of the flue, keeps animals from nesting, and stops water from pooling in the smoke chamber and rusting the damper. In Exton, where so many homes have exterior masonry stacks, a missing or undersized cap accelerates spalling because every rain event soaks the brick from the inside.
Chimney cap installation in Exton runs $120 to $380 for a standard stainless cap sized to a single flue, installed. Multi-flue caps run $300 to $550. Custom caps for odd-sized or historic chimneys can run higher, but we quote those in writing too. We stock caps from Copperfield and Olympia Chimney for most common flue sizes, which means we can usually install the same week we inspect. If your existing cap is original to an older Exton house, it’s likely galvanized steel and rusted through; we’ll show you that in the photo report.
Stainless Steel vs. Galvanized Caps
Stainless caps cost more up front, but Chester County weather eats galvanized caps in five to seven years. Stainless lasts decades and doesn’t rust drip stains down the brick. We spec stainless by default on exterior masonry chimneys.
When a Cap Alone Fixes the Problem
If the crown is still intact and the flue liner is sound, a new cap is sometimes the entire repair. We don’t invent masonry work where none is needed. If the camera inspection shows a dry flue and the crown is solid, we’ll tell you the cap is all you need.
Trusted Brands We Service in Exton
We work with professional-grade chimney products from manufacturers that make their specs public: DuraFlex for flue liners, Olympia Chimney and Copperfield for caps and chimney covers, Famco for vents and dampers. Because we stock common parts for the Exton market, most cap work and damper replacement happens in a single visit. You should be able to verify the materials going on your chimney independently, and we name the brand on every quote so you can. That’s part of The Garrison Standard we operate under at Flint Chimney Sweep.
Common Chimney Repair Problems We See in Exton Homes
- Freeze-thaw spalling on exterior masonry stacks. Exton’s winter temperature swings send water into the brick face, where it freezes and pops the brick surface. This shows up on repointing and spall repair calls here far more than interior flue problems do.
- Cracked crowns on chimneys built in the 1970s and 1980s. A lot of Exton’s housing stock along Route 100 and around the Whitford area went up in that era, and those crowns are now past their service life. Cracks let water track down into the smoke chamber.
- Missing or undersized caps on older flue setups. Rain and animals get in, the damper rusts, and the brick wicks moisture from inside. A cap would have prevented most of the masonry work we quote.
- Third-degree creosote glaze hiding behind a clean firebox. On repair calls where the homeowner sweeps the firebox themselves, the flue liner often hasn’t been camera-inspected in years. The masonry looks fine, but the real hazard is baked-on creosote inside the liner that a brush won’t remove.

FAQs About Chimney Repair in Exton
Most masonry chimneys in Exton need some form of repair, usually repointing or crown work, every 15 to 25 years, depending on exposure and how well the cap has held up. A cleaning is annual or seasonal depending on use. The honest answer we give Exton homeowners is this: if the chimney hasn’t been camera-inspected in five years, the inspection comes first because it tells you which side of that timeline you’re on. We don’t recommend masonry work without photo evidence, and we’ll say plainly when the chimney can safely wait another season. Call (830) 251-4560 and we’ll schedule the camera inspection that answers it.
A proper repair on an Exton masonry chimney starts with a Level 2 camera inspection, which means we run a camera up the flue and take photos of the liner, the smoke chamber, and the crown from above. Then you get a written quote with a flat price for exactly the work shown in the photos. On the Waterloo Boulevard job, for example, the photos showed the crumbling crown and spalled top course before we touched anything, and the homeowner approved the repair knowing precisely what it covered. After the work, you get a photo report showing before-and-after at each stage. This is how we do every repair in Exton, no exceptions.
No. Third-degree creosote is a hardened, glazed deposit that bonds to the flue liner, and a standard chimney brush won’t remove it. We use professional mechanical removal methods and in some cases a chemical treatment to break it down. This matters on repair calls because a flue with third-degree glaze is a chimney fire risk even if the firebox looks clean. If our camera inspection finds glazed creosote, we’ll tell you plainly, show you the photos, and quote the removal separately from any masonry repair. Call (830) 251-4560 if you haven’t had your flue inspected in a few years.
We don’t promise same-day repair, and you should be wary of any company that does. A proper repair in Exton requires a camera inspection first, a written quote you can review, and often time for mortar to cure or parts to arrive if your flue size isn’t one we stock. We schedule repair work within a week of the inspection in most cases, and cap installation often happens the same week. We book repairs, we don’t run emergency calls, because cutting corners on a chimney is how you end up with water in the firebox two winters from now. Call (830) 251-4560 and we’ll get your inspection on the schedule.
We service and install DuraFlex flue liners, Olympia Chimney and Copperfield caps and covers, and Famco dampers and vents. If your existing cap or liner is from another manufacturer, we can usually source a replacement or recommend the correct retrofit. We name the brand on every quote so you can verify the spec independently. That’s mandatory under The Garrison Standard, not optional. Call (830) 251-4560 and we’ll tell you what’s on your chimney now and what it should be replaced with.
