Fast, Reliable Chimney Repair Across Florissant
If your fireplace is smoking back, your crown is cracked, or your brick is spalling, you’re in the right place. Chimney repair in Florissant usually means masonry and flue work on a house built between the 1950s and 1970s, and that older construction calls for a closer look than a quick sweep. We know the postwar brick ranches and split-levels that make up so much of this town, and we know what their chimneys were built to handle and what they weren’t. One call covers the sweep, the inspection, and the repair, so you’re not juggling contractors. Call (866) 596-7310. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Florissant Homeowners Call Hawk Chimney Sweep for Chimney Repair
Most of the repair work we see in Florissant traces back to the same thing: a clay-tile flue built for an open fireplace, now serving an insert, a gas appliance, or nothing at all. Those stacks are often oversized for what’s venting into them, and many were never relined. That mismatch is where bad advice happens, so our team leads with the camera and shows you what’s actually in your flue before anyone recommends a repair.
We serve Florissant as part of our St. Louis-area work, and we’re familiar with the housing on both sides of the Missouri River bottoms: the brick ranches off Lindbergh, the split-levels near the old town center, and the quieter blocks out toward Spanish Lake. Our technicians have up to 12 years of experience, and they inspect from cap to firebox rather than stopping at the brush.
We’re licensed and insured, and every job is priced by a written estimate you get before we start. When you call about a chimney repair in Florissant, you get a straight answer about what’s safe to schedule now and what can wait. Call (866) 596-7310 for a free estimate.

Chimney Masonry Repair in Florissant
Chimney Masonry Repair in Florissant is mostly about water and the damage a St. Louis-area winter does to brick and mortar. Repeated freeze-thaw cycles crack mortar crowns and open joints, water gets in, and the next hard freeze spalls the face off the brick around the firebox. A typical mortar repointing job on a Florissant chimney runs $450 – $1,100, while spalling brick repair that replaces damaged units and rebuilds the affected courses runs $700 – $2,000 depending on height and access. Full crown rebuilds sit in the $600 – $1,500 range. The written estimate fixes the final price.
Repointing Joints Before They Fail
Repointing means grinding out the failed mortar and packing new mortar into the joints, which stops water from working behind the brick. On a Florissant ranch, the lower courses and the crown area usually need it first. Catching this early keeps a small repointing job from turning into a rebuild.
When a Rebuild Is the Honest Call
If the brick face has spalled deep, the crown is gone, and the flue tiles are cracked, patching it stops being worth the money. A partial or full rebuild is the sounder choice, and we’ll show you the photos before you decide. Tuckpointing and waterproofing often go on the same job so the new masonry is protected from the start.
Chimney Cap Installation in Florissant
Chimney Cap Installation in Florissant is the single cheapest defense against the water that drives most of the masonry damage here. A cap keeps rain out of the flue and keeps birds, squirrels, and raccoons from nesting in an open stack. Installation typically runs $250 – $650 depending on the flue size, the material, and whether a custom cap is needed for an odd crown. A cap paired with crown repair is the usual package on these older brick chimneys.
Custom Caps for Odd Crown Shapes
Not every Florissant chimney has a square, level crown, and a stock cap on a bad crown leaks worse than no cap. Custom stainless caps built to the actual flue measurement are worth the extra cost when the shape is irregular.
Why the Dampers and Crowns Go Together
A top-sealing damper and a cap solve the same problem from two ends: keeping water and cold air out of the flue when the fireplace isn’t in use. On a ranch where the crown is already cracked, doing both at once saves a return trip. It’s a small addition that pays for itself in avoided masonry work.
Trusted Brands We Service in Florissant
We install and work with professional-grade products, and the brands we use reflect that standard. For flue resurfacing on a cracked or spalling clay-tile liner, we use HeatShield, a repair method most sweep-only companies can’t offer. For full relining, DuraFlex flexible liner systems give a code-compliant flue sized correctly for what’s venting into it. We also work with Gelco and Olympia Chimney components where the job calls for them. These are installed per job, not stocked from a warehouse, so turnaround stays quick. When we recommend a product, we tell you why and show you the video evidence behind it.
Common Chimney Repair Problems We See in Florissant Homes
- Water damage from a cracked crown. Freeze-thaw cycles open the crown, water gets into the flue, and the brick around the firebox spalls. That’s the most common reason a Florissant homeowner calls us for masonry work.
- “Sleeping” fireplaces in 63031. In the older sections of town, fireplaces were sealed off during the 1970s energy crisis and never reopened. When a homeowner finally tries to light one, the damper is often deteriorated and an animal nest is still inside.
- Clay-tile flues serving modern inserts. A postwar stack sized for an open fire is oversized for an insert or gas appliance, and the glaze buildup a brush won’t touch shows up fast. A camera tells you whether it’s a sweep job or a reline.
- Smoke rolling back on the first fire of the season. A damper that won’t open, a partially blocked flue, or a failed crown letting water in all mimic the same symptom. A Level 2 inspection finds the real cause instead of guessing.

FAQs About Chimney Repair in Florissant
It usually needs relining, not a repair patch. The original clay tile was sized for an open fire, so it’s oversized for a modern insert and often unlined in stretches, which means a correctly sized flexible liner is the safe answer. A camera look confirms it. Call (866) 596-7310 for a free estimate – you’ll see the video before anything is recommended.
Because our winters repeatedly freeze and thaw, and water sitting on an unprotected crown splits it open again each season. A patch alone never holds. The fix is a proper crown rebuild with the right slope and a waterproof seal, and it’s usually the start of a masonry package. Call (866) 596-7310 for a free estimate.
Get a Level 2 inspection before you light anything. A sealed fireplace usually has a deteriorated damper and animal nesting inside, and the flue can look sweep-ready when it actually needs repair first. Treat it as unknown until the camera says otherwise. Call (866) 596-7310 for a free estimate.
You should be shown the camera footage of your own flue before any repair is recommended. Ask what the video shows: the clay-tile condition, the crown cracking, and the creosote degree. If a company can’t show you that, walk away. We include camera inspection and a photo report, and we tell you when work can wait. Call (866) 596-7310 for a free estimate.
Yes, especially on this town’s older masonry chimneys. Water intrusion and spalling happen whether or not you burned, and a dormant flue is a favorite spot for animal nesting. An inspection catches the damage before it turns into a rebuild. Call (866) 596-7310 for a free estimate.
What the Camera Should Show You
Here’s the part that matters most when you’re deciding on a repair in Florissant. You should see three things on the camera video: the condition of the clay-tile flue, any cracking in the chimney crown, and the degree of creosote on the flue walls. That’s how you tell a sweep job from a repair job and a repair job from a reline. When water is getting in through a cracked crown and spalling the brick around the firebox, the camera and the masonry tell the same story. Nothing here gets recommended without that evidence in front of you. Call (866) 596-7310 for a free estimate, and we’ll show you what we find.
