What We Do
We handle every part of the chimney system, from the firebox at the bottom to the cap at the top. Here is what that looks like in practice.
We install rigid stainless steel liner systems and cast-in-place liners. Stainless works well when the flue is straight and sized correctly. Cast-in-place fills cracks in older clay tile systems and works in offset flues where rigid liner cannot navigate the bends.
Camera findings decodedAnnual sweeping removes creosote before it reaches third-stage buildup, which is flammable and difficult to remove without chemical treatment. We include a video inspection with every sweep so you can see the liner condition yourself.
Chimney cleaning DallasNorth Texas clay soil expands and contracts with moisture changes, which puts stress on brick and mortar joints every season. We handle repointing, crown repair, partial rebuilds, and full chimney reconstruction depending on what the damage actually calls for.
Partial vs full rebuildWe install and service fireplace inserts, gas log sets, and damper systems. If your existing fireplace is inefficient or drafts poorly, an insert installation can significantly improve both performance and safety.
Insert installation FriscoDallas summer storms push water into uncapped or unprotected flues. We apply penetrating waterproofer to brick and install stainless caps that keep rain, debris, and animals out year-round.
Why chimney caps matter in DallasA Level 1 inspection covers accessible portions of the chimney. Level 2 is required when buying or selling a home, or after a chimney fire or significant weather event. Both include a written report.

Safe Flue Chimney Sweep And Repair works in Flower Mound, TX and across the Dallas metro. We provide chimney sweeping, inspection, relining, masonry repair, rebuild, and fireplace services. One crew handles the full scope of work.
Flower Mound homes tend to be built in the 1990s and early 2000s, which means a lot of clay tile liner systems are now 25 to 30 years old. Clay tiles crack from thermal cycling and from the movement that comes with North Texas expansive clay soils. By the time the cracks are wide enough to see from the firebox, the liner has often been compromised for years.
The only way to know liner condition is a camera inspection. We run a camera down the flue before recommending any relining work. That image record protects you and it keeps us honest.
We work in neighborhoods throughout Flower Mound including the lakefront communities near Grapevine Lake, the older subdivisions off FM 2499, and homes in the Wellington area. If you're in Highland Village or Argyle, we cover those too.
We speak plainly about what your chimney needs. If a sweep is all that's required, that's what we recommend. We don't upsell relining when it isn't warranted, and the camera footage backs that up.
These are realistic figures drawn from the trade. Your specific job depends on chimney height, liner diameter, offset angles, and the condition of the existing system.

Common Questions
These are the questions we get most often from homeowners in Flower Mound, Highland Village, and the surrounding communities. Call us at (214) 441-6336 if yours isn't here.
Inspection cost guide 2026The short answer is: you need a camera inspection to know for certain. Symptoms like heavy smoke backdraft, visible cracks in the firebox, or a strong odor from the fireplace even when it's not in use all suggest liner problems. But none of those signs are conclusive on their own. We run a camera to the full depth of the flue so you can see cracks, gaps, and offset tile edges directly. Many homeowners assume they need a new liner when they actually need a sweep and minor repair, and vice versa.
Stainless steel liner systems are installed as rigid or flexible sections that run through the existing flue. They work well in straight or gently offset flues and are the most common choice. Cast-in-place systems involve pouring a lightweight insulating concrete around an inflatable form inside the flue. The result is a smooth, continuous liner that bonds to the existing masonry. It's the better choice for flues with significant offsets, irregular shapes, or heavily deteriorated clay tile where the tile itself provides structural support for the poured liner. See our guide on clay liner vs stainless for Dallas homeowners for a detailed comparison.
Most standard relining jobs take 4 to 8 hours and are completed in a single visit. That includes the pre-job camera inspection, the liner installation, insulation where required, top plate sealing, and a post-installation draft test. More complex jobs, such as a two-story exterior chimney with multiple offsets, or a cast-in-place installation, can take a full day and in some cases require a second visit for the form removal. We give you a realistic timeline before we schedule.
Permitting requirements for chimney liner installation vary by municipality. In Flower Mound, mechanical permits may be required for liner work connected to gas appliances. We can advise you on what's needed for your specific job. Skipping required permits creates problems at home sale time, since a Level 2 inspection prior to transfer of ownership will identify unpermitted work. It's worth getting it done correctly the first time.
North Texas has some of the most expansive clay soil in the country. When soil moisture changes, the ground shifts. That movement transfers directly to your home's foundation and, from there, to the chimney structure. Brick chimneys are rigid by nature, so they absorb that movement as cracks, especially in mortar joints. Homes near the Grapevine Lake drainage areas and along the creek corridors in western Flower Mound tend to see this more than homes on elevated ground. See our detailed breakdown of how North Texas clay soil cracks brick chimneys.
No. A cracked liner is a fire and carbon monoxide risk. The liner's job is to contain combustion gases and heat inside the flue until they exit through the top. Cracks allow those gases to reach combustible framing and insulation inside your walls. This is not a theoretical risk, it's the mechanism behind most chimney-related house fires. If a camera inspection finds liner damage, stop using the fireplace until the liner is repaired or replaced. We understand that's inconvenient, but there's no safe workaround. Read more about what liner inspection after a chimney fire involves.
Cost varies significantly with chimney height, liner diameter, offset complexity, and liner type. A stainless liner on a straightforward single-story flue costs less than a cast-in-place installation on a two-story exterior chimney with multiple offsets. We can give you an accurate quote after the camera inspection. For general guidance, see our 2026 chimney sweeping cost guide and the inspection cost guide for context on what the overall service spectrum looks like in this market.
