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.

Chimney repair in Lake Dallas typically runs $185 – $340 for cap replacement, $900 – $2,600 for flue liner installation, and $1,800 – $4,500 for partial chimney rebuilding. Most jobs are diagnosed with a camera inspection the same visit, and every repair leaves with a written one-year guarantee. If you’re in Lake Dallas and water is getting past the cap or the liner is cracked, call (830) 251-4560 and we’ll walk you through what’s happening before anyone steps foot on the ladder.
We know this stretch of Denton County. Lake Dallas sits on the south shore of Lewisville Lake, and that lakefront position changes how chimneys fail here. Wind-driven rain hits caps and flashing harder than it does in inland towns like Argyle or The Colony, and we account for that before recommending any repair. Booking is simple: a flat written price before work begins, a background-checked technician in uniform at the door, and a camera report showing exactly what we saw. No vague estimates. No moving the number when the truck pulls up.
Why Flint Chimney Sweep Is Lake Dallas’s Preferred Chimney Repair Company
Homeowners around Lakeview Park, East Hill Park, and the neighborhoods off Swisher Road call us because the process is predictable. You get a written price before any work starts. That price is the price. If a covered repair fails within one full year, we return at no charge. That guarantee is written on every invoice, not mumbled over the phone.
Hank Delano leads our crews, and he holds the team to the Garrison Standard: document everything, honor the window, and leave the work area cleaner than we found it. That matters in Lake Dallas, where chimneys take weather off the lake that inland flues never see. We specify materials by the job, not by margin. That means a Lake Dallas home near the waterline may get a stainless steel cap base instead of galvanized, because we have seen what two storm seasons do to the cheaper option.
Our team dispatches from the Dallas-Fort Worth office and serves Lake Dallas locally. When you call (830) 251-4560, a live person answers. Not a callback form. Not a voicemail tree. A human being who can book your inspection and tell you what to expect.
- 365-Day Done Right Promise: written guarantee on every repair, valid one full year from service date.
- Flat written pricing: the number on the invoice is the number you approved before work started.
- Camera inspection included: you get a photo report showing what we found. Nothing is recommended without evidence you can see.
- Background-checked, uniformed technicians: you know exactly who is walking through the door.
Chimney Cap Replacement in Lake Dallas
Chimney cap replacement is the single most common repair we perform in Lake Dallas because Lewisville Lake storms bend, rust, and blow caps off more often than most homeowners expect. The cap sits on top of the flue and keeps rain, birds, and debris out. When it fails, water drops straight down onto the damper and into the firebox. A standard single-flue cap replacement in Lake Dallas runs $185 – $340, including the new cap, removal of the old one, and resealing. Stainless steel and copper caps land at the higher end; galvanized at the lower end.
When a Cap Needs Replacing, Not Straightening
A bent cap usually cannot be straightened back to a proper fit. Once the metal has creased, it will not seal against the flue correctly, and the next storm will push water through the gap. We replace bent caps on a stainless steel base, which resists the wind better than a painted steel base.
What We See Near the Waterline
Homes within a few blocks of Lewisville Lake, especially off Lakeshore Drive and around Lakeview Park, lose caps at roughly twice the rate of homes further inland. We were called to a home in the Lakeview Park area after a storm dumped water into the firebox during a rainstorm. Our tech found the original 6-inch steel cap bent in by wind, with water staining the damper and spalling on the chimney crown. We installed a new copper cap on a stainless steel base and resurfaced the crown, then ran a Level 2 inspection and gave the homeowner a photo report showing no liner damage.
Chimney Liner Installation in Lake Dallas
Chimney liner installation involves replacing the inner liner that channels smoke safely out of the house. In Lake Dallas, we see two drivers behind liner failure: third-degree creosote that glazes the flue and eats at the liner wall over time, and water entering through a failed cap that accelerates deterioration from the inside. A full liner installation in Lake Dallas runs $900 – $2,600, depending on the flue dimensions, the liner material, and whether the old liner must be broken out first.
When the Liner Has to Go
If a camera inspection shows cracks, gaps, or a heat-warped section, the liner cannot keep smoke, heat, and carbon monoxide contained. That is not a maintenance item. It is a repair deadline. We will show you the footage before we quote the job, so you can see the crack yourself and know the recommendation is not invented for a sale.
Materials We Specify
For Lake Dallas homes, we install DuraFlex and HeatShield liners because they hold up to the moisture and thermal cycling common in lakeside flues. DuraFlex handles high-efficiency gas and oil appliances. HeatShield is a resurfacing system that rebuilds the interior of an existing clay liner when full replacement is not needed. The right material depends on the flue size, the appliance, and the condition of the surrounding masonry, and we will explain the trade-off in plain words before you commit.
Trusted Brands We Service in Lake Dallas
We work with professional-grade chimney products from Famco, Copperfield, DuraFlex, and HeatShield. That matters because Lake Dallas chimneys need components that can take lake wind and heavy rain. A Copperfield cap on a stainless base, for example, holds its shape through storm season better than the thin steel caps installed by some builders. We keep common replacement parts stocked so most Lake Dallas cap and crown repairs can be completed on the first visit, without a second trip to a supply house.
Common Chimney Repair Problems We See in Lake Dallas Homes
- Wind-bent and rusted caps. Lewisville Lake fronts push rain sideways into caps and flashing. If you can see daylight through the cap from below, water is already inside the chimney.
- Spalling crowns and water-stained dampers. Rain hitting a cracked crown soaks the masonry below it. We see this after storm season in homes from East Hill Park to the neighborhoods along Hundley Drive.
- Third-degree creosote glaze. Heavily used fireplaces in Lake Dallas develop a hard, tar-like glaze inside the flue. A standard brush will not remove it, and a Home Depot sweep will not either. This is a chemical or rotary-clean job, not a simple $99 special.
- Cracked refractory panels and warped fireboxes. Factory-built fireboxes in homes near Lake Dallas often read as “smoke filling the room” or “bad draft.” The real issue is a cracked panel or warped metal wall that needs repair, not a bigger cap.

FAQs About Chimney Repair in Lake Dallas
A Lake Dallas chimney should get a visual check or camera inspection every year, but actual repair is driven by condition, not a calendar. Near the lake, caps and flashing often need replacement every 8 – 12 years because of wind and rain exposure. A liner can last 20 – 30 years if the cap keeps water out and the fireplace is not overused. If you have not had the flue looked at in more than two years, start there. Call (830) 251-4560 and we will schedule an inspection with a camera report you can see.
It is a replacement. A bent cap will not seal against the flue, and the next lake storm will push water through the gap. We price cap replacement in Lake Dallas at $185 – $340, and we will show you the damage before we quote the new cap. Call (830) 251-4560 to get a written price for your specific flue.
Yes. Every repair starts with a camera inspection so you can see the crack, the rust, or the creosote glaze yourself. We do not recommend liner work or crown repair from a guess. The photo report is yours to keep, and it gives you a record of the chimney’s condition that insurance or a home sale may require later.
Third-degree creosote is a hard, shiny glaze that bonds to the flue liner. A standard chimney brush will not remove it. We use chemical treatments and rotary cleaning systems to break the glaze down, then re-inspect with the camera to confirm the liner is clean and intact. Call (830) 251-4560 if you suspect your flue has glazed creosote, and we will tell you what the camera shows before recommending any work.
Yes. We install both DuraFlex stainless steel liners and the HeatShield resurfacing system, choosing the material based on the flue dimensions, the appliance, and the extent of the original liner damage. A full liner installation in Lake Dallas runs $900 – $2,600. Call (830) 251-4560 for a free estimate with a written price before any work starts.
If you are in Lake Dallas and you suspect a cap, flashing, crown, or liner problem, do not wait for the next storm to make it worse. Call (830) 251-4560 today and we will get a camera in the flue, show you what we found, and put a written price in your hands before any tool comes off the truck.
