Two Kinds of Chimneys in DFW
- Brick chimneys. Masonry chimneys that pass through the roof. They depend on step flashing and counter flashing to keep water out where the brick meets the shingles.
- Framed chimney chases. Common on many DFW homes: a wood-framed box around a metal flue, covered in siding. They depend on the siding, paint and flashing to stay dry, and when those fail the framing inside rots.
Signs Your Chimney Needs Repair
- Water stains on the ceiling or wall near the fireplace.
- Peeling paint, soft or swollen siding on the chimney chase.
- Gaps, rust or lifted metal where the chimney meets the roof.
- Siding sitting directly on the shingles at the base of the chase.
- Daylight, wasps or animals getting into the chase.
Chimney Chase Rebuild, Step by Step
When a chase has rotted, patching the siding only hides the problem. Here is how we rebuild one:
- Strip it down. Old siding and sheathing come off so we can see the framing.
- Reframe. Rotted studs and plates are replaced around the flue.
- Sheathing and house wrap. New sheathing goes on, wrapped to shed water.
- Flashing. New flashing is installed where the chase meets the roof, lapped with the shingles so water runs out, not in.
- Siding and paint. New siding goes on with a gap above the shingles, then trim and paint to match the house.
Brick Chimney Flashing Repair
On a brick chimney, the flashing is layered: step flashing woven into the shingles along the sides, and counter flashing set into the brick that laps over it. When the flashing has rusted, pulled out of the mortar, or was covered in tar instead of being replaced, water gets in every rain.
We remove the old flashing, repair any rotted decking around the chimney, install new step and counter flashing, and shingle back in around it.
Chimney Repair During a Roof Replacement
If your roof is being replaced, that is the right time to replace the chimney flashing and check the chase. The shingles are already off, so the work is easier and it all ties into the new roof. Learn more about roof replacement and roof repair.
Free Inspections, Financing and Storm Damage
Chimney repairs are priced on the size of the chimney, how much is rotted, and the siding and flashing needed, so we inspect first and give you a free written estimate. Financing is available, as low as 0%. After a hail or wind storm, we document the damage to the chimney and roof with photos and meet your insurance adjuster. Se habla español.
Chimney Caps and Chase Covers
The top of the chimney takes more weather than any other part of it. A chimney cap or chase cover keeps rain out of the flue, keeps birds, squirrels and raccoons from nesting inside, and stops sparks from landing on the roof. When the cap is missing or rusted through, water runs straight down the flue or into the chase and shows up as a leak near the fireplace.
- Chimney caps. A chimney cap sits over the top of the flue with a mesh screen around it and a small roof on top. Chimney cap installation is quick, and it is one of the cheapest ways to stop a chimney leak.
- Stainless steel chimney caps. A stainless chimney cap will not rust like a painted or galvanized cap, so it lasts far longer in our wet springs and hot summers.
- Chimney chase covers. On a framed chimney, a chimney chase cover (also called a chimney chase cap) is the metal pan that covers the whole top of the chase. Old galvanized pans rust, sag and hold water, which then runs down inside the chase and rots the framing. We replace them with a new cover that is sloped or crowned so water runs off.
- Chimney cap replacement. If your chimney cover is rusted, bent by wind or missing its screen, chimney cover replacement is a small job that protects everything below it.
If you are searching for chimney repair near me because of a leak by the fireplace, a missing cap or a rusted chase cover is one of the first things we check.
Chimney Crown, Masonry and Tuckpointing
On a brick chimney, the crown is the cement slab at the top that sheds water away from the flue. Crowns crack as they age and as the chimney moves with our clay soil, and water that gets into those cracks works down into the brick. We seal small crown cracks and rebuild crowns that have broken apart.
The mortar between the bricks wears out too. Tuckpointing means grinding out the loose, crumbling mortar and packing in fresh mortar, so the joints are tight again and water stays out. We also replace cracked or spalling bricks. Fixing the crown, the mortar joints and the flashing together is what stops a brick chimney from leaking for good.
