Chimney Repair in Flower Mound Starts With an Inspection
Flower Mound Chimney Sweep Professionals does not quote a chimney repair from the driveway. Every repair visit begins with the same check we do on a sweep: a camera up the flue, a look at the damper, smoke chamber and firebox, and a trip to the roof to check the crown, cap, flashing and chase. You get photos of each problem and a written price for fixing it. Then you decide.
That order matters because chimney damage hides. A stain on the ceiling near the fireplace can come from the crown, the flashing, the cap or the brick itself, and each one is a different repair at a different price. Fixing the wrong one is the most common way homeowners pay twice.
Flower Mound has two kinds of chimneys, and we repair both:
- Masonry chimneys of brick, mortar and clay flue tile, common in older homes near Grapevine Lake and Lake Lewisville. They need crown, mortar and flashing work as they age.
- Factory-built (prefab) chimneys, a metal firebox and flue inside a wood-framed chase wrapped in siding or brick veneer, standard in neighborhoods built from the 1990s on such as Bridlewood and Wellington. They fail at the chase cover, the cap, the storm collar and the siding.
Signs Your Chimney Needs Repair
- Water stains on the ceiling or wall next to the chimney
- Rust streaks running down the siding or brick from the top
- White powder (efflorescence) or flaking brick faces
- Cracks in the crown or gaps around the flue tile at the top
- Mortar joints you can scrape out with a key
- A chimney that leans or shows a stepped crack
- A rusted, missing or loose cap
- Smoke coming back into the room, or a musty smell after rain
One of these is a reason to book an inspection. Spring hail and the storms that follow it are the biggest single cause of chimney damage in Flower Mound, so a roof check after a bad storm is worth the call.
Chimney Crown Repair
The crown is the concrete slab that seals the top of a masonry chimney around the flue. Builders often poured a thin mortar wash instead of a real crown, and after twenty North Texas summers it cracks. We seal hairline cracks with a flexible crown coating, patch larger cracks, or pour a new crown with a drip edge. Details are on the chimney crown repair page.
Chimney Flashing Repair
Flashing is the metal that seals the joint where the chimney meets the roof. Hail dents it, 100 degree summers cook the sealant, and roofers sometimes leave it short after a shingle replacement. We reseal, re-bed the counter flashing into the mortar joint, or replace the step flashing. See chimney flashing repair.
Chimney Leak Repair
A leak is a symptom, not a part. On a chimney leak repair visit we test the crown, cap, flashing, chase cover and brick, find the entry point, and fix that one thing first. The page covers the five places water gets in and how we tell them apart.
Chimney Cap Installation
A cap keeps rain, embers, squirrels, raccoons and chimney swifts out of the flue. A missing or rusted cap is the cheapest chimney problem to fix and one of the most common ones we find. We install stainless steel single-flue, multi-flue and custom caps, sized to the flue. See chimney cap installation.
Chimney Chase Cover Replacement
On a prefab chimney, the chase cover is the metal lid on top of the wood chase. Builders used galvanized steel, and it rusts through in 10 to 15 years, which is why so many 1990s and 2000s homes in Flower Mound have rust stains on the chase. We replace it with a stainless cover, cross-broken so water runs off. See chimney chase cover replacement.
Chimney Waterproofing
Brick is porous. A breathable water repellent applied after repairs keeps rain out of the masonry while letting moisture inside escape. It is the last step on a crown, tuckpointing or rebuild job, not a substitute for one. See chimney waterproofing.
Chimney Tuckpointing
When mortar joints wear back or crumble, we grind them out and refill them with mortar matched to the original in strength and color. Done early, chimney tuckpointing stops water from reaching the bricks and puts off a rebuild by decades.
Chimney Rebuild
When the damage goes past the joints, a partial rebuild from the roofline up, or a full rebuild, replaces the failed masonry with new brick, flue tile, crown and cap. Leaning chimneys, spalled brick across large areas and chimney fire damage are the usual reasons. See chimney rebuild.
Other Chimney Repairs We Handle
Cracked flue tiles get a stainless steel liner through chimney relining. A damper that is stuck open or rusted shut is a chimney damper repair. A fireplace that smokes with a clean flue is a draft problem, covered under chimney downdraft repair. Rotted chase framing is a chimney siding and chase repair.
