Fast, Reliable Chimney Repair Across Lake Highlands
Chimney repair in Lake Highlands typically runs $300 – $2,400 depending on what’s actually wrong, and most jobs are completed in a single visit. We work the neighborhoods between White Rock Creek and Richardson ISD every week, so we know what these 1960s and 1970s chimneys do when they fail. If you’re seeing water stains on the ceiling, hearing animals in the flue, or noticing brick pieces in the firebox, call (361) 492-4099 and we’ll put a written price in your hand before any work starts.
The homes here were built with clay tile flues and brick veneer that’s now 50 to 70 years old. That’s not a criticism, it’s a fact of the housing stock. Our Chimney Repair team has mapped the common failure points across Lake Highlands, from the Rolling Trails tract homes to the larger two-story builds off Ferndale and Skillman. We quote from what the camera shows, not from a sales script.
Why Flint Chimney Co Dallas Is Lake Highlands’s Preferred Chimney Repair Company
We operate under the Garrison Standard, the same code every Garrison Partners location follows. That means a written price before work begins, a background-checked technician in uniform at your door, and a repair that carries a 365-Day Done Right Promise in writing. If a covered repair fails within one full year, we return at no charge. No argument, no invoice. That’s the Garrison Code.
Our crew lead in this area, Hank Delano, has been running repair calls across Lake Highlands long enough to know which 1960s tracts used which flue tile dimensions, and which two-story footprints have the hard-to-reach dampers. Homeowners near the Lake Highlands Town Center and up through the L Streets tell us the same thing: the quote we wrote before starting is the invoice they paid at the end. Phones are answered by a live person 24/7, so when a winter cold snap hits and your fireplace starts smoking back into the den, you’re not leaving a voicemail.
Styles & brands we work with





Chimney Cap Replacement in Lake Highlands
Chimney cap replacement in Lake Highlands is the repair we recommend most often after our camera inspection, because the area’s mature pecan and oak canopies drop limbs straight onto the cap. A standard galvanized or stainless cap replacement in Lake Highlands runs $285 – $675 installed, depending on flue size and whether the mounting plate needs rebuilding. When the cap rusts through or tears, rain pours directly down the flue and raccoons move in, which pushes smoke back through the firebox during the first winter burn.
Cap Styles For Older Brick Chimneys
Most Lake Highlands chimneys have either a single-flue clay tile protruding from the crown or a multi-flue setup on larger two-story homes. We stock caps sized for both, including Copperfield and Olympia Chimney units. The cap gets anchored with stainless fasteners into the crown, then sealed with a Gelco crown coat so water can’t work under the mounting edge.
When A Cap Alone Isn’t Enough
If the crown under the old cap has crumbled, replacing just the cap leaves the chimney vulnerable. We’ll show you the crown damage on camera and quote the cap and crown repair as one line item. In Lake Highlands, we often see crowns cracked from the same freeze-thaw cycle that spalls the brick below the roofline. The written quote covers the whole scope, so there’s no “we found something else” moment mid-job.
Chimney Liner Installation in Lake Highlands
Chimney liner installation in Lake Highlands commonly runs $1,900 – $4,200 for a full reline with a DuraFlex stainless system, sized to the existing flue and the appliance or fireplace it serves. The liner is the inner channel that moves smoke and exhaust safely out of the house, and the original clay tile liners in 1960s and 1970s builds crack along the vertical joints. Once those joints open, heat and gas reach the brick and framing where they don’t belong.
Relining Clay Tile Flues
We don’t replace a clay tile liner just because it’s old. We camera the flue first and show you the footage. If there are hairline cracks that haven’t spalled, HeatShield resurfacing can sometimes buy years of safe service for less than a full reline. When tiles are cracked through, shifted, or missing, a DuraFlex liner is the fix that carries our written one-year guarantee.
Sunken Den Fireplaces Need Mapping
This is the one repair issue that’s genuinely Lake Highlands-specific. The 1970s sunken den fireplaces on the Richardson ISD side have dampers recessed so deep that the throat geometry varies from house to house. Before we quote a liner job on those, we map the throat and smoke chamber with a bore-scope. A national chain will often price the job blind and find the problem after they’ve started. We don’t quote what we haven’t measured.
Trusted Brands We Service in Lake Highlands
We install and service HeatShield, Gelco, and Olympia Chimney products on repair calls across Lake Highlands, and we keep common cap and crown sealant inventory on the truck so most jobs finish same-day. You can look up any of these brands independently and see what they’re built to do. We specify materials by the job, not by our margin. If a specific cap or liner system fits your chimney, we quote that exact product with the part number in your written estimate.

AfterCommon Chimney Repair Problems We See in Lake Highlands Homes
- Clay tile spalling in 1960s ranches. The vertical joints crack first, then water from the occasional freeze-thaw cycle works into those gaps and pops tile shards into the firebox. If you’re finding tan-colored tile pieces on the hearth, the flue needs a camera look before the next burn.
- Seized dampers on sunken den fireplaces. The damper linkage rusts solid from humidity, then someone forces the lever and bends the rod. After that the damper never seats, so cold air drafts back into the room all winter.
- Cap failures under the oak canopy. Mature pecan and oak limbs dent or tear the chimney cap, and once there’s an opening, raccoons nest in the flue. A blocked flue pushes smoke back through the firebox opening, which is how we get called the first week of December.
- Spalling brick at the roofline. The same humidity that causes efflorescence on brick veneer also lets water soak the mortar joints on exposed chimney stacks. Left alone, that turns into spalling brick and mortar that needs repointing or selective rebuilding.
Pricing for Chimney Repair in Lake Highlands, TX
A standard chimney cap replacement in Lake Highlands runs $285 – $675. Mortar repointing and waterproofing typically land between $400 and $1,100 depending on the height of the stack and the amount of exposed brick. Flashing repair around the roofline runs $350 – $800. A full chimney rebuild starts around $2,200 and goes up from there based on how much of the stack needs to come down. Liner installation, as noted above, runs $1,900 – $4,200.
What moves the price is usually access: a steep roof pitch off Ferndale costs more in time than a walkable ranch roof.

FAQs About Chimney Repair in Lake Highlands
Hairline cracks without displacement can sometimes be resurfaced with HeatShield, which we apply as a ceramic coating that restores a smooth, insulated flue surface for less than a full reline. But cracked-through, shifted, or missing tiles cannot be safely coated, because the coating can’t restore structural integrity to a flue that’s already broken. The only way to know which camp your chimney falls into is a camera inspection. We’ll show you the footage and quote the appropriate fix. Call (361) 492-4099 for a free estimate.
The damper assemblies on those 1970s sunken den fireplaces are recessed deeper into the throat than standard ranch-style fireplaces, and the surrounding masonry traps humid air from the room. That humidity rusts the linkage solid, and the first hard pull on the lever bends the rod. After that the damper never seats. We map the throat with a bore-scope before any repair on these, which is why our quotes on sunken dens take a little longer but come back accurate.
With two wood-burning fireplaces and an oak canopy, every year. The oak limbs damage caps and the heavy winter use builds creosote faster than a single-fireplace home. An annual inspection catches cap tears and early spalling before they turn into a $3,000 repair. Sweep before burning season, inspect at the same visit. That’s the schedule we recommend for Lake Highlands homes with this profile.
Yes, in most cases. Spalling brick that’s limited to a few courses at the roofline can be selectively cut out and replaced, with the surrounding mortar repointed and the whole stack waterproofed after the patch cures. A full rebuild is only necessary when the spalling has compromised the structural core or when more than a third of the exposed stack is failing. We’ll show you the extent on camera and quote only what’s actually needed.
The cap looks fine from the ground but has rusted through at the seam where the mounting plate meets the flue opening. Water gets in behind the cap, runs down the flue, and the homeowner sees no exterior damage until the firebox damper starts rusting or water stains appear on the ceiling. In Rolling Trails and similar 1960s tracts, we regularly find third-degree creosote glazing on the clay tile flue behind a rusted-through cap. The fix is a new cap and crown seal, which runs $285 – $675 in Lake Highlands. Call (361) 492-4099 and we’ll camera the flue and show you exactly what’s going on.
