Chimney Repair in Alpharetta, GA

A chimney leak in Alpharetta rarely starts as a leak. It starts as a hairline crack in the crown during a July thunderstorm, works through the brick over the fall, and shows up as a brown stain on the ceiling next to the fireplace after the first hard freeze in January. By then the damper is rusted and the firebox floor is damp. The repair is still straightforward. It is just bigger than it needed to be.

Chimney Repairs We Do in Alpharetta

Every repair below starts with photos and a free written estimate from our Alpharetta office.

Chimney Crown Repair

The crown is the sloped concrete slab that seals the top of a masonry chimney. Hairline cracks are sealed with a flexible elastomeric crown coat. A crumbling or flat crown with no overhang is rebuilt so water drips clear of the brick. Crown failure is the single most common chimney repair we photograph in north Fulton.

Chimney Flashing Repair

Flashing is the metal that seals the chimney to the roof. It lifts, rusts, or was never counter-flashed into the mortar joints to begin with. We reseal, replace or re-step the flashing so water stops running down the outside of the chimney into the attic.

Chimney Leak Repair

When the source is not obvious, we find it: crown, flashing, cap, porous brick or a cracked chase cover on a prefab chimney. The photo report shows you the entry point, and the estimate covers only that. Waterproofing with a breathable masonry sealer is added when the brick itself is soaking up rain.

Brick and Mortar Repair

Spalling brick (faces popping off), open mortar joints and white efflorescence stains are water damage. Repointing replaces the failed mortar, spalled brick is cut out and replaced to match, and the chimney is sealed afterward. Larger stone and brick work is covered on our masonry repair page.

Damper and Firebox Repair

Rusted dampers that will not seal waste heat all winter and let humid air in all summer. We replace throat dampers and install top-sealing dampers. Cracked firebrick and failed firebox mortar are repaired with refractory mortar so the firebox stays safe to use.

Flue Liner Repair and Relining

Cracked clay flue tiles and gaps between them let heat and gases reach the wood framing. A stainless steel liner, sized to the fireplace or insert, solves it. Details and liner types are on our chimney relining page.

Chimney Cap and Chase Cover Replacement

A missing cap lets rain, squirrels and chimney swifts straight into the flue. On factory-built chimneys the rusted chase cover is usually the real leak. Both are replaced with stainless steel, custom fitted. See chimney cap installation.

How Much Does Chimney Repair Cost in Alpharetta?

Every Ember chimney repair in Alpharetta starts with a free written estimate. The price depends on what the photos show, so we do not quote a chimney repair over the phone. For a sense of scale, Angi’s 2026 data puts most chimney repairs between $160 and $750, with an average of about $455. Crown sealing, flashing and damper work sit at the low end. Repointing a whole chimney, a stainless liner or a partial rebuild sit well above the average. Our chimney repair cost guide goes through each repair type.

Two things keep the price honest:

• Photos of the problem. You see the crack, the gap or the rust before you see a number.
• The $149 credit. Book the repair within 30 days of a $149 Chimney Safety Package visit and the full $149 is credited toward it.

Signs Your Alpharetta Chimney Needs Repair

• A water stain on the ceiling or wall beside the fireplace, or water on the smoke shelf.
• White, chalky stains (efflorescence) on the outside brick.
• Brick faces flaking or popping off, or mortar you can scrape out with a key.
• Rust streaks on the chase cover or down the siding of a prefab chimney.
• A damper that sticks, will not seal, or has flakes of rust falling into the firebox.
• Pieces of clay tile or mortar in the firebox after a storm.
• Smoke coming into the room, or a fire that will not draw.
• The chimney looks like it is leaning or a gap is opening between the chimney and the siding.

Any one of these is reason to book a chimney inspection in Alpharetta. The $69 inspection or the $149 package includes the photos that turn into the repair estimate.
