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.
Fast, Reliable Chimney Repair Across Forest Hill

Most repairs are completed in a single visit, and every one carries a written one-year guarantee. If you’re seeing rust stains, spalling brick, or water in the firebox, call us at (830) 251-4560 and we’ll give you a written price before any work starts.
We know Forest Hill’s housing stock. Brick ranches off Forest Hill Drive, older frames near Anglin Drive, postwar builds along Wichita Street. They share a problem most chimney companies never mention: rail-yard and grain dust settles on roofs, works into mortar, and eats crowns and flashing faster than in cleaner suburbs. That’s local knowledge, and it shapes how we inspect and repair every chimney in this city.

Chimney Flashing Repair in Forest Hill
Chimney flashing repair is the single most common chimney masonry job we do in Forest Hill, and it usually runs $450 – $1,200 depending on how much flashing has to be cut out and replaced. Flashing is the metal barrier where the chimney meets the roofline. In Forest Hill, the failure pattern is predictable: decades of grain dust and diesel soot settling on the roof create a mildly acidic grit that works into the flashing seam and corrodes the seal. Water gets behind it, leaks into the attic or down the chimney chase, and the homeowner sees a brown stain on the ceiling or rust streaks on the brick.
We replace failed step flashing and counter flashing with materials from Copperfield and Famco, specified by the job rather than by margin. When we quote flashing repair in Forest Hill, the written price includes removal of the old metal, new flashing, sealant, and a water test before we pack up.
Step Flashing Replacement
Step flashing is cut in short right-angle pieces and layered into the shingle courses as the roof climbs toward the chimney. Forest Hill homes built in the 1950s and 1960s often have original galvanized step flashing that has rusted through. We pull the damaged sections, install new metal with proper overlap, and re-seal every seam.
Counter Flashing and Sealant Failure
Counter flashing is the metal set into the mortar joint and folded down over the step flashing. When mortar around it cracks, the counter flashing pulls loose and water drives straight behind it. In Forest Hill this accelerates because dust grit expands and contracts in the joint during freezes, even the short North Texas cold snaps. We grind out the joint, re-set the metal, and repoint the mortar with a matching mix.
Chimney Crown Repair in Forest Hill
Chimney crown repair in Forest Hill typically runs $550 – $1,600, and it’s the job we recommend most often after camera inspections in this city. The crown is the concrete or mortar slab that caps the top of the chimney and sheds water away from the flue. When it starts spalling, meaning the surface crumbles into sandy patches, water soaks into the masonry below. In Forest Hill the trigger is almost always the same: airborne grain dust from the old ag barns area and diesel particulates from the Fort Worth & Western Railroad corridor settle on the crown, mix with rainfall into a mild acid, and eat the surface faster than clean-air suburbs.
We repair crowns two ways. Minor spalling gets a new crown coat with proper slope and drainage. A crown that has cracked through gets removed and re-poured, usually with a formed concrete crown that overhangs the chimney edge. Costs depend on access and whether scaffolding is needed.
Crown Recoating
If the crown is cracked but structurally intact, we grind the surface, fill the cracks, and apply a new crown coat with positive drainage. This is a same-visit repair on most Forest Hill single-story ranches.
Poured Replacement Crown
When the old crown has spalled deep or separated from the flue, we form and pour a new one. The new crown overhangs the brick course by about two inches and slopes away from the flue, so water never pools. We use a mix designed for North Texas freeze-thaw cycles.
Trusted Brands We Service in Forest Hill
We stock and install professional-grade chimney materials from Olympia Chimney, Famco, and Copperfield, so Forest Hill customers aren’t waiting on a backordered part from a distributor. That matters when you have open flashing or a cracked crown and a rain front is moving in. These are trade brands, the kind masonry supply houses carry, not big-box substitutes. When we quote a repair, the written price names the exact material going on your chimney. If a cap, a flue component, or a flashing piece is replaced under warranty, the same brand is used on the return visit.
Common Chimney Repair Problems We See in Forest Hill Homes
- Crown spalling from grain-dust and rail fallout. Forest Hill sits near the Fort Worth & Western Railroad and just south of the former Castleberry ISD ag barns, and the airborne grit accelerates acidic breakdown of mortar crowns. Homes within a mile of the rail corridor show crown wear 5 to 10 years ahead of comparable suburbs.
- Flashing separation at the roofline. The dust settles in the flashing seams, holds moisture, and corrodes the seal. We see it most on 1950s and 1960s ranches where the original flashing was never upgraded.
- Third-degree creosote hiding behind a damaged flue liner. A visual Level 1 inspection won’t catch it. Our camera inspection goes inside the flue and documents what’s there, so you’re not guessing about whether the chimney is safe to burn.
- Rust stains on brick above the firebox. This usually means water is getting in from the top, either through a failed cap, a cracked crown, or separated flashing. The rust is the symptom, not the problem. We trace the water path before quoting any repair.
Pricing for Chimney Repair in Forest Hill, TX
Flashing repair in Forest Hill runs $450 – $1,200. Crown repair runs $550 – $1,600, whether it’s a recoat or a full re-pour. Mortar repointing runs $35 – $60 per square foot. Spalling brick replacement runs $45 – $80 per brick. Chimney waterproofing runs $350 – $800 for a standard single-flue chimney. A partial rebuild above the roofline starts around $1,800 and goes up with height and access.
What changes the price is access: a two-story Forest Hill roof with a steep pitch costs more than a single-story ranch because of scaffolding and safety setup. The chimney’s condition matters too, but you’ll know exactly what we found because we show you the camera footage before we quote. Estimates are free. Call (830) 251-4560 and we’ll give you a written number.

FAQs About Chimney Repair in Forest Hill
Once a year is the straight answer for a chimney that gets regular use, and that holds in Forest Hill because the airborne dust from the rail yard and former ag barns accelerates creosote buildup and mortar wear. If your chimney has sat unused for years, start with a Level 2 camera inspection before burning anything. Call (830) 251-4560 to schedule one.
Third-degree creosote is a hard, glazed tar that forms when a chimney burns hot and then cools fast, especially with restricted airflow. It will not come off with a brush. It has to be chemically treated or removed with specialized rotary tools. And if it’s hiding behind a damaged flue liner, it’s a chimney fire waiting for a hot fire. We document what’s there with a camera before we touch it, so you’re not paying for a treatment you don’t need.
No, we don’t. We schedule repairs for the next available opening, and we tell you that when you call. What we promise is a written price before work starts, a background-checked tech who shows up inside the window given, and a one-year guarantee on everything we repair. If a covered repair fails in that year, we come back and fix it free. Call (830) 251-4560 for the next available slot.
Usually not, but it needs to be looked at. Rust stains above the firebox mean water is entering from somewhere above, typically a failed chimney cap, a cracked crown, or separated flashing. The repair can often wait a few weeks while you get a proper inspection, especially outside burning season. Our camera inspection pinpoints the entry point, and then we give you a written quote. You decide when to schedule. Call (830) 251-4560 for an inspection.
Forest Hill is bordered by the Fort Worth & Western Railroad and sits just south of the former Castleberry ISD ag barns. Grain dust and diesel soot from that corridor settle on roofs and into mortar joints, and when rain hits, it forms a mild acid that breaks down crowns and corrodes flashing seals faster than in cleaner-air suburbs. We see the difference in the field: Forest Hill chimneys show the same water damage as Fort Worth chimneys a decade older. That’s why our inspections here always include a close look at the crown and flashing surfaces, not just the flue.
