Rain, squirrels, birds, embers, and downdrafts all use the same door: an open flue. A properly fitted stainless cap closes it for decades, installed in one visit, usually in under an hour.
Here's the strange economics of chimney cap installation in Dallas Fort Worth: it's one of the least expensive services on this entire website, and it prevents more damage than anything else we sell. An uncapped flue is an open pipe pointed at the Texas sky, every storm delivers water directly into your damper, firebox, and liner, and every spring delivers a family of squirrels or a federally protected bird looking for real estate.
Lowes Chimney Sweep installs stainless steel and copper caps, fabricates custom and multi-flue caps for chimneys the shelf doesn't fit, repairs and re-anchors storm-damaged caps, and builds in spark arrestors and animal guards as standard equipment. Most installations finish the same visit as the quote, the fastest five-star review we earn, across all 98 DFW cities.
Missing cap, rusted cap, or something scratching in the flue? Call (214) 225-8874, this is often a today-or-tomorrow fix.
Sized to your flue, mechanically anchored, and sealed. We install stainless steel as the default, because half our cap work is replacing the rusted galvanized ones that came before, and we'd rather you never repeat that cycle.
Caps that rattle in the wind, sit crooked after a storm, or have loose mesh often just need proper fastening and a screen replacement. When repair genuinely beats replacement, that's what we quote.
Odd-size flues, two or three flues sharing one chimney, or a home where the chimney top deserves better than mismatched hardware, measured on-site and fabricated to fit, in stainless or copper.
The mesh that keeps burning embers off your roof and out of your neighbor's dry August lawn. Built into every cap we install, with mesh sized to stop sparks without choking your draft.
Squirrels, raccoons, and chimney swifts treat open flues as move-in-ready housing. We remove residents humanely and legally, swifts are federally protected and get special handling, then cap the flue so the vacancy sign comes down permanently.
Every week uncapped adds water damage. Call (214) 225-8874, standard caps usually install the same visit.
Short project, real method:
Exact dimensions and flue type, the difference between fitted and flying off
Crown, tiles, and mortar inspected while we're up there, with photos
Cap, material, and price in writing, standard sizes often install immediately
Rusted or failed hardware comes off and leaves with us
Fastened to the flue tile or crown, not friction-fit to blow away
Level, sealed, and clear airflow confirmed before we climb down
Before-and-after shots of your chimney top, no ladder required to verify our work
Stainless steel, mechanically anchored, spark mesh included, usually installed the same visit as the quote.
(214) 225-8874You can, a galvanized one, in whatever size the shelf had, friction-fit from a ladder. The reason half our cap installations are replacements is exactly that combination: wrong size, rust-prone metal, no anchoring. A fitted stainless cap installed once beats a cheap cap installed three times, and we're happy to show the math.
You don't have to, that's the measuring visit. Flue dimensions, single or multi-flue, wood or gas venting, and the condition of the crown all shape the answer. You get a specific recommendation in writing, not a guess from the driveway.
Especially then. A cap stops the water that's making every existing problem worse. It pairs naturally with crown repair, the cap protects the flue opening, the crown protects the masonry shoulders around it, and together they seal the entire top of the system.
Always. The top of your chimney is territory most homeowners never see, so every cap visit includes a photo check of the crown, flue tiles, and upper masonry. If something's wrong up there, you'll see the pictures, and if nothing is, you'll know that too.
We install the material that survives Texas weather by default. Nobody leaves our schedule with a cap we already know rusts.
Mechanical fasteners into tile or crown on every install. North Texas storms are our cap-replacement sales team, we decline their help.
Every install includes a photographed check of the crown and upper masonry, a mini inspection included in the trip up the ladder.
Under an hour on the roof, but measured, anchored, sealed, and photographed. Quick is a feature; sloppy never is.

In the Dallas Fort Worth area, standard stainless steel caps typically run $200 to $500 installed, larger multi-flue and custom-fabricated caps $500 to $1,500, and copper or specialty designs above that. The exact number depends on flue size, chimney height, and roof access, and you'll have it in writing as a Free Online Quote before we're on the roof.
Yes, an uncapped flue is an open pipe to the sky. Rain pours straight in, birds and squirrels move in, leaves pile up, and downdrafts push cold air and odors into the house. A cap is the single cheapest piece of protection a chimney can have, which is why every inspection report flags a missing one.
Water is the main villain: every storm sends rain down the flue, rusting dampers, soaking firebrick, and feeding mold and musty smells. Add animal nests that block airflow and become fire hazards, plus debris that traps moisture year-round. The repairs that follow, dampers, liners, firebox work, cost many times what the cap would have.
Enormously. Galvanized caps are the cheap ones on big-box shelves, and Texas weather rusts them in a handful of years. Stainless steel costs somewhat more and routinely lasts decades, most come with lifetime warranties. Copper is the premium option for homes where the chimney is an architectural feature. We install stainless as the default because replacing rusted galvanized caps is half our cap business.
Don't light a fire, and don't try to smoke it out, that ends badly for everyone. Some animals leave on their own; others, like nesting chimney swifts, are federally protected and must be left until they fledge. Call us: we'll assess what's in there, handle removal humanely and legally, then cap the flue so it never happens again.
A spark arrestor is the mesh screen built into a quality cap that stops burning embers from escaping onto your roof or a neighbor's yard. In a North Texas summer, when lawns are tinder-dry, that mesh is genuinely important fire protection. All the caps we install include arrestor mesh sized to keep embers in and airflow open.
When the flue is an odd size or shape, when multiple flues share one chimney and deserve one clean full-coverage cap instead of two mismatched ones, or when you want the cap to match the home's style. Custom fabrication is measured on-site and built to your chimney, not forced from whatever the shelf had.
It usually means the original was undersized, corroded at the fasteners, or attached with friction alone. A properly sized cap mechanically fastened to the flue tile or crown shrugs off DFW wind storms. We install with mechanical anchors as standard, and if hail or wind destroyed the old one, that damage is often insurable.
Yes, gas venting needs rain and animal protection just like wood flues, though the cap must match the vent type to preserve proper draft. Prefab gas systems usually pair a listed cap with the chase cover beneath it. We confirm the right cap for your specific venting rather than putting a wood-stove cap on a gas flue.
Standard caps install in under an hour once we're on-site, measure, anchor, seal, done, usually the same visit as the quote. Custom and multi-flue fabrications need a measuring visit first, then fabrication time, then a short installation appointment. Either way it's the quickest meaningful upgrade a chimney can get.
The cap guards the flue opening, these services protect everything around and below it:

A cap only works if it fits the flue and seats on sound masonry, so we measure the flue tile, check the crown it bolts to, and look for existing water or animal damage before recommending anything. A cap on a crumbling crown is a bandage on a broken bone.
Missing caps entirely, builder-grade caps rusted through after a decade, screen mesh clogged solid with creosote, caps sized wrong so they choke draft, and caps that blew off in a storm because they were friction-fit instead of bolted.
Rain straight down the flue destroys liners and rusts dampers. Birds, squirrels, and raccoons treat an open flue as a den. Sparks exiting the flue land on your roof. The cap is the cheapest insurance on the whole chimney system.
Stainless steel single-flue caps for most homes, multi-flue and custom-made chimney caps for wide or unusual crowns, and copper when the home calls for it. We quote a ballpark from photos and confirm the final price on site.
Glance at it after big storms and have the mesh checked during your annual inspection, because a screen packed with creosote chokes the draft. Stainless caps mostly just work, which is exactly why we install them.
If water damage already cracked the crown or spalled the brick, capping it locks the problem underneath. Crown and masonry repair come first, then the cap. We will tell you the order and why.
