Why Hearthstone Chimney Co. Is Flower Mound’s Preferred Chimney Repair Company

We’ve been driving to Flower Mound for Chimney Cleaning & Sweep - Flower Mound since the town was still figuring out how big it would get. That matters because the chimney problems we find in a 1997 tract home off Gerault Road are nothing like what we see in a 1970s ranch near Lake Lewisville, and treating them the same way wastes your money.

Our technicians carry the right parts for Flower Mound’s dominant prefabricated fireplace systems - the factory-built units installed by the thousands during the 1990s and 2000s buildout. That stockpile means fewer return trips, which means your fireplace is working when you need it.

Russell Haines built this company in 1984 on the idea that a chimney sweep should explain what he found the way he’d explain it to his own neighbor. Forty-two years later, that still means photos you can see, a plain-English verdict, and a written estimate before any work starts.

Calls come to a live person 24 hours a day. No voicemail. No callback queue. No app.

Our Chimney Repair Services in Flower Mound

Mortar Repointing

The heavy Blackland Prairie clay beneath Flower Mound doesn’t stay still. In the 75022 neighborhoods near the lake, where older masonry chimneys weren’t built on piers deep enough to outlast the soil shift, we regularly find mortar joints that have opened in a stepped pattern - a signature of foundation movement, not ordinary weathering. Our repointing and Chimney Liner & Rebuild - Flower Mound services match the original mortar composition and compressive strength so the repair moves with the wall instead of cracking again next season. Typical repointing on a Flower Mound masonry chimney runs $800-$1,800 depending on access and how many courses need work.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - shows up in Flower Mound when moisture gets behind the brick and freeze-thaw cycles push the face off. It’s more common on north-facing chimney walls and on homes where the original builder used softer, lower-grade brick. We cut out spalled units, install matching brick where possible, and address the water source so it doesn’t repeat. Most spalling repairs in Flower Mound fall between $450 and $1,200.

Chimney Waterproofing

Flower Mound’s proximity to Lake Lewisville pushes ambient humidity higher than you’ll find in drier Collin County suburbs. That moisture, combined with the temperature swings of North Texas winters, finds every gap in a chimney’s exterior defense. We apply vapor-permeable sealers that let the masonry breathe while blocking liquid water, and we always pair waterproofing with crown repair or Chimney Cap & Crown in Flower Mound work so you’re not sealing water inside. A full waterproofing treatment on a Flower Mound chimney typically costs $350-$650.

Flashing Repair

Leaks at the roof-chimney intersection are the call we get most often after ice storms, and Flower Mound’s thin-gauge galvanized flashing on prefab chases is especially vulnerable. We fabricate and install custom step flashing and counterflashing using professional-grade materials, sealed with high-temp sealants that outlast the builder-grade caulk most installers used. Flashing repair in Flower Mound generally runs $400-$950.

Trusted Brands We Service in Flower Mound

We stock parts from Famco, Copperfield, and DuraFlex in our service vehicles because Flower Mound’s prefabricated fireplace population demands it. A cracked refractory panel in a HeatShield-compatible unit or a rusted chase cover from a Gelco or Olympia Chimney system shouldn’t mean a two-week wait for shipping. Our technicians carry the common sizes and configurations for the builder-grade brands installed during Flower Mound’s residential boom, which is how we complete most repairs in a single visit.

Common Chimney Repair Problems We See in Flower Mound Homes

• Rusted galvanized chase covers on prefab units. The factory-built fireplaces installed across Flower Mound’s 1990s and 2000s subdivisions came with thin galvanized steel chase covers that corrode faster here due to Lake Lewisville’s elevated humidity. Homeowners often mistake the resulting leaks for roof failures.
• Cracked refractory panels reaching end of service life. Those same prefab units are now 20-35 years old, and their factory refractory panels - the heat-facing walls inside the firebox - are cracking and thinning en masse. This is a fire hazard, not a cosmetic issue, and it defines our repair workload in Flower Mound in a way it simply doesn’t in older Dallas neighborhoods full of traditional masonry.
• Stepped mortar cracks from expansive clay soil movement. In the lakeside 75022 area and other pockets with masonry construction, the Blackland Prairie clay swells and shrinks with moisture changes. We find mortar joints that have opened in a stair-step pattern, sometimes with the chimney crown tilted - a structural issue that requires repointing and often foundation assessment before relighting season.
• Failed flashing after ice storms. North Texas ice storms come infrequently but hard, and the ice damming that follows lifts and separates poorly installed flashing. Flower Mound’s prefab chase flashing, often installed with minimal step flashing and caulked seams, is particularly susceptible.
