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.

AfterTrusted Chimney Cap & Crown for Denton Homeowners
A chimney cap and crown in Denton, TX typically costs $280-$890 depending on whether you’re installing a new cap, replacing a rusted unit, or repairing a cracked crown. Most jobs are completed in a single visit, and every project starts with a camera inspection so you see the condition before we quote a price. Call (940) 373-6912 to schedule your free estimate.
We’ve inspected and serviced more than 38,000 chimneys since 2009, and the cap and crown issues we find in Denton follow a clear pattern. The combination of North Texas clay soils, seasonal expansion and contraction, and our sudden spring hailstorms creates stress fractures in concrete crowns that homeowners don’t notice until water stains appear on the ceiling near the fireplace. In neighborhoods like Southridge, Oakmont, and the older homes around the University of North Texas, we regularly see original crowns from the 1970s and 1980s that have never been sealed, with spalling concrete and exposed rebar. Our home page explains our full inspection standard, but for cap and crown work specifically, we bring the same NFPA 211 Level 2 documentation: photos, written scope, written price, and a record you keep. Corrine Halstead leads our operations, and our technicians are background-checked, uniformed, and licensed.
What Our Chimney Cap & Crown Service Includes
Cap Installation
Cap installation protects your flue from rain, animals, and debris while allowing proper draft. You need a cap when your chimney has none, when the flue is open to the elements, or when you’ve had birds or squirrels nesting above the smoke chamber. In Denton, we install stainless steel and copper caps from Olympia Chimney and Famco, sized to your flue count and diameter, with a written price before we start and a photo record of the finished work under our Chimney Cap & Crown in Denton service standards.
Cap Replacement
Cap replacement becomes necessary when the existing unit is rusted through, blown off in a storm, or improperly sized from a previous installation. We see this often in Denton’s Robson Ranch and Lantana communities, where builder-grade galvanized caps fail within five to seven years. We remove the old cap, inspect the flue tile for damage the old cap may have hidden, and install a replacement with a proper fit and animal-proof screening.
Crown Repair
Crown repair addresses cracks, spalling, or deterioration in the concrete slab that tops your chimney structure. In Denton, clay soil movement and freeze-thaw cycles open hairline cracks that widen each season, funneling water directly onto the masonry below. We chase cracks to sound concrete, apply a bonding agent, and patch with crown-specific mortar rated for thermal expansion, then document the repair with before-and-after photos.
Crown Coating
Crown coating is a preventive treatment for crowns with minor cracking that haven’t yet failed structurally. We apply a flexible, waterproof membrane formulated for chimney crowns, not generic concrete sealer, which bridges small cracks and sheds water for years. This is most cost-effective for Denton homeowners whose crowns are five to fifteen years old and showing early wear but no major spalling.
Multi-Flue Cap
Multi-flue caps cover chimneys with two or more flues emerging from a single crown, common in homes with fireplaces and furnaces sharing the chimney structure. These require precise measurement and proper clearances to avoid draft interference or overheating. We fabricate and install multi-flue caps from Gelco and Copperfield with outside-mount designs that protect the entire crown edge, not just the flue openings.
Custom Cap
Custom caps serve chimneys with unusual dimensions, decorative shrouds, or historical requirements, particularly in Denton’s historic districts and custom builds in areas like Canyon Oaks. We measure on-site, specify materials and gauge, and provide a written quote with fabrication timeline. Every custom cap carries the same 365-Day Done Right Promise as our standard installations.

Brands We Service for Chimney Cap & Crown
We’ve installed and serviced hundreds of Gelco caps since 2009, and we stock their stainless steel single-flue and multi-flue models through our Haven buying network. Gelco’s mesh design handles Denton’s spring hail without deforming, and their lifetime warranty transfers with the home, which matters for our clients in fast-appreciating neighborhoods like Oak Hills.
Olympia Chimney and Famco round out our primary cap suppliers. Olympia’s galvanized and stainless lines fit the budget-conscious homeowner in Corinth or Sanger who needs reliable protection without premium pricing. Famco’s copper and black galvanized caps suit the aesthetic requirements we see in Lantana and Highland Village, where HOA guidelines specify finish and color. We also work with Copperfield for specialty flashing and custom fabrication. Whether you have one of these brands or any other make, we can inspect it, repair it, or replace it with a documented photo record on every visit.
BeforeAfterSigns You Need Chimney Cap & Crown Right Now
- Water stains on the ceiling near your fireplace. This indicates your crown or cap has failed and moisture is migrating down the flue or through masonry joints. Left unaddressed, it damages drywall, insulation, and framing, and in Denton’s humid summers, mold follows within weeks.
- Rust flakes or stains on the firebox floor or damper. Rust means water is entering from above, either through a missing cap, a cracked crown, or deteriorated flue tiles. The damper is steel; once it rusts solid, replacement costs exceed preventive cap or crown work by a significant margin.
- Visible cracks or crumbling on the chimney crown surface. Hairline cracks widen with thermal cycling, and Denton’s temperature swings from 20°F winter nights to 100°F summer days accelerate the damage. Spalling concrete exposes the chimney’s structural masonry to saturation and freeze-thaw deterioration.
- Animal sounds or debris in the flue. Squirrels, raccoons, and chimney swifts enter open flues readily, and their nesting material is a fire hazard. A proper cap with animal-proof mesh prevents entry; if you’re hearing activity, the cap is missing, damaged, or improperly screened.
- White efflorescence or green algae on exterior brick below the crown. These stains signal chronic moisture intrusion, often from crown cracks that channel water into the masonry rather than shedding it. The masonry below degrades progressively, and repointing or rebuilding becomes necessary if the source isn’t corrected.
Our Chimney Cap & Crown Process - Step by Step
- 1
Schedule and confirm. Call (940) 373-6912 or reach us through our live answering service, available 24 hours a day, 7 days a week. We confirm your Denton address, note any symptoms you’ve observed, and assign a named technician with a background-checked, uniformed crew. You’ll receive a text when they’re en route.
- 2
NFPA 211 Level 2 inspection with camera scan. Before quoting any cap or crown work, we run a camera down the flue to document interior condition and inspect the crown, cap, flashing, and masonry from the roof. This is Haven Standard Clause 4: a documented photo record on every visit, standard since 2009, not an optional add-on. You see what we see.
- 3
Written price, scope, and warranty. We deliver a written quote before any work begins, specifying materials, labor, and timeline. Haven Standard Clause 1 requires this: “Have it in writing.” No verbal estimates, no surprises after the technician is already on your roof. Our 365-Day Done Right Promise is stamped on every job.
- 4
Cap or crown work with photo documentation. We complete the agreed scope, whether that’s cap installation, crown repair, coating, or custom fabrication. Materials come from our Haven buying network, and we photograph each stage for your record. If we find additional issues during work, we stop, show you, and quote separately before proceeding.
- 5
Final inspection and documented record. We verify proper fit, draft function, and water shedding with a post-work camera scan and exterior photos. You receive a written completion summary with photos, warranty terms, and maintenance recommendations. This record supports insurance claims, home sales, and future service planning.
How Much Does Chimney Cap & Crown Cost in Denton?
A typical stainless steel cap installation in Denton runs $280-$450 for a single flue, depending on flue diameter, mesh gauge, and whether the flue tile requires repair before mounting. Multi-flue caps range from $480-$720. Crown repair with crack chasing and patching costs $340-$580; full crown rebuilds when the concrete is too deteriorated to patch run $680-$890. Crown coating as preventive maintenance is $280-$420, most cost-effective for crowns with minor cracking and intact structural integrity.
Several factors move these ranges. Accessibility matters: steep pitches, two-story heights, or limited roof access add labor time. The condition of existing flashing and the need for sealant or counterflashing replacement affects material costs. Custom fabrication for non-standard dimensions or HOA-mandated finishes carries a premium over stock sizes. We source materials through our Haven buying network specifically to keep customer prices honest, and we never markup hidden.
To avoid overpaying, get the scope in writing and verify what’s included. Our quotes specify cap brand and gauge, crown repair materials, warranty terms, and whether the price includes the NFPA 211 Level 2 inspection. Competitors who charge separately for “inspection” and “repair” often quote a lower initial number that climbs once they’re on-site. We include the camera scan and photo record on every visit. Bring us any competitor’s written estimate for a Free Second Opinion.

Frequently Asked Questions - Chimney Cap & Crown in Denton
The cap is the metal cover that sits over your flue opening to keep out rain, animals, and debris while allowing smoke to exit. The crown is the concrete slab that tops your chimney structure, sloped to shed water away from the masonry below. You need both because the cap protects the flue interior and the crown protects the chimney structure; either one failing allows water intrusion that damages your chimney, fireplace, and adjacent framing.
Most cap installations and crown repairs are completed in two to four hours on a single visit. Custom cap fabrication typically requires one to two weeks for manufacturing plus the installation visit. We schedule morning or afternoon windows and text you when the technician is en route, so you’re not waiting indefinitely. Call (940) 373-6912 for availability.
Cap installation runs $280-$450 for single flue, $480-$720 for multi-flue; crown repair is $340-$580; crown rebuilds are $680-$890; and crown coating is $280-$420. Every quote is written and delivered before work starts, with no hidden fees. The exact price depends on your chimney’s dimensions, accessibility, and condition, which we determine during our included camera inspection. Call (940) 373-6912 for a free estimate.
Yes. We install and service Gelco, Olympia Chimney, Famco, and Copperfield caps regularly, and we stock common sizes and mesh configurations for faster turnaround. If you have a different brand or an older unit we don’t stock, we can fabricate a replacement or adapt a compatible model. Bring us any existing documentation or photos for accurate quoting.
A missing or damaged cap should be addressed before the next rain event, as open flues collect water that rusts dampers and degrades liners. Crown cracks can wait weeks if they’re minor and no water intrusion is evident, but they worsen with each freeze-thaw cycle. We prioritize urgent cases and will tell you honestly when work can safely wait versus when delay risks structural damage or safety hazards.
Every job carries our 365-Day Done Right Promise: if it’s not done right, we make it right. Manufacturer warranties on caps vary by material, stainless steel typically carries lifetime coverage, while copper and galvanized have shorter terms. Crown repairs and coatings are warranted against material defect and workmanship for one year. All warranty terms are written on your completion document, not verbal.
Ensure roof access is clear, move vehicles from the driveway if the technician needs to stage a ladder there, and secure pets. You don’t need to clean the fireplace or move furniture; we lay drop cloths and protect your flooring. Have any prior inspection reports or competitor estimates available if you want a Free Second Opinion. We’ll handle the rest and leave you with a documented photo record.
