Chimney Repair in Durham - You See the Footage Before You Get a Price

Trusted Chimney Repair for Durham Homeowners

Durham Chimney Sweep is a chimney and venting specialist with a full year of focused experience: we’ve been serving Durham and the surrounding towns since 2015. Older homes around Trinity Park, Watts-Hillandale, and the neighborhoods off Club Boulevard often have masonry flues that have absorbed decades of heat, creosote, and weather. Add the piedmont’s humid summers and freeze-thaw winters, and the mortar joints and crowns on those chimneys take a beating. When something gives way, we repair it so the flue keeps doing its one job: moving smoke and combustion gases out of your home. Call (866) 389-3509 to get a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Chimney Cap Installation

Chimney Cap Installation is the first line of defense for a Durham flue, a fitted cover that keeps rain, birds, squirrels, and leaves out of the opening while letting smoke escape. You need one if your chimney has no cap, or if the cap you have has rusted out or rusted loose. We install caps made by brands like Olympia Chimney and Copperfield, sized to the flue instead of bolted on loosely. A standard single-flue cap typically runs $150-$350 installed, depending on flue size and how the cap must be mounted. Multi-flue chimney tops and custom sizes run more, and we’ll put the number in a written estimate before any work starts.

Measure Before You Mount

A cap that’s even an inch too wide lets wind-driven rain in around the edges, and one that’s too small won’t sit flush. We measure the actual flue opening, not the outside of the crown, and check for a sound surface to anchor to. Rotted or cracked crowns get flagged at that stage.

Stainless Steel vs. Galvanized

Galvanized caps are less expensive and hold up reasonably well in North Carolina, but stainless steel resists rust longer where humidity sits heavy. We carry both and tell you plainly which makes sense for your chimney. It’s your call, and we’ll install either the same visit.

Chimney Cap Replacement

Chimney Cap Replacement is the right call when the existing cap has gone past repair: rusted through, bent by a fallen limb, or loose enough that wind rattles it. Durham’s storm seasons send enough branches and wind through residential neighborhoods that damaged caps are common, and a loose cap does more harm than no cap if it’s grinding into the crown. We pull the old cap, check the flue tile and crown for damage underneath, and set a new cap from our professional line. Replacement typically runs $150-$350, similar to new installation, since most of the cost is the cap itself and the labor to fit and anchor it correctly. We don’t leave a gap where a cap came off without making sure the chimney top is sound.

What to Look For From the Ground

If you can see daylight between the cap and the flue, or the cap sits crooked, it needs attention before the next hard rain. Rust streaks running down the masonry are another sign. Both are easy to spot with binoculars, no climbing.

Why a Leaky Cap Matters

An uncovered flue lets water run straight down into the firebox and into the masonry. Over enough seasons, that water erodes mortar and spalls brick. Fixing the cap is often far cheaper than fixing the damage below it.

Chimney Liner Installation

Chimney Liner Installation is the heavy repair, creating or replacing the flue lining that protects the masonry from heat and keeps combustion gases inside the chimney where they belong. You need a new liner when a camera inspection shows cracked or missing clay tiles, gaps at the joints, or a flue that’s too small or oversized for the appliance it serves. We install flexible liner systems, including DuraFlex, and use the HeatShield resurfacing system for flues that can be restored rather than fully relined. A full liner installation typically runs $1,800-$4,500 depending on flue height, liner type, and whether an insulated wrap is needed. A HeatShield resurfacing job usually comes in lower when the flue qualifies. We’ll show you camera footage before recommending either.

Clay Tile vs. Flexible Liner

Original clay tile does the job until it cracks, and age or a past chimney fire can crack it. A flexible stainless liner creates a continuous, sealed passage inside the old flue, so you get the protection back without demolishing the chimney. We’ll explain which route your flue actually needs.

Insulation and Draft

An insulated liner holds heat in the flue, which keeps the draft strong and reduces creosote buildup. On a tall exterior chimney, that difference is noticeable. We’ll tell you when insulation is worth the added cost and when it isn’t.

Chimney Flashing Repair

Chimney Flashing Repair seals the joint where the chimney meets the roof, a spot that’s one of the most common sources of roof leaks around Durham homes. You need it when flashing is pulling away, the sealant has failed, or you’ve noticed water stains on the ceiling near the chimney. We reset or replace the flashing, step it into the shingles correctly, and seal against the masonry with the right materials for the job. Flashing repair typically runs $300-$800 depending on roof pitch, the extent of the damage, and whether the shingles around it need to be reset. We don’t charge to look at it: the estimate is free, and we’ll tell you whether it’s a flashing problem or something higher up the chimney.

Signs the Flashing Has Failed

Water on the ceiling near the chimney, dampness inside the attic at the chimney penetration, or visibly lifted flashing at the roofline. Rusted nails and rotted roof decking show up when it’s caught early. Left alone, the leak spreads.

Why Sealant Alone Isn’t Enough

Smearing caulk over failed flashing works for one season at most. Water gets behind the step flashing and runs down the roof deck. Proper repair means getting the metal and the shingles working together again.

Chimney Crown Repair

Chimney Crown Repair addresses the concrete top of the chimney, the slightly sloped surface that sheds water away from the flue. When a crown cracks or crumbles, water runs into the chimney’s interior, and that water freezes, expands, and splits the masonry further. Durham sees enough freeze-thaw cycles in a normal winter for a cracked crown to get worse fast. We repair or rebuild crowns with a proper slope and seal, and we check the flue tile while we’re up there. Crown repair typically runs $400-$1,200 depending on the size of the chimney and how much of the crown must be rebuilt. We’ll show you photographs of the crown before and after.

Cracks vs. Crumbling

A hairline crack can often be sealed. A crown that’s cracked through, spalling, or separating from the flue needs rebuilding. The difference matters for cost and for how long the fix lasts.

Why the Slope Matters

A crown that’s flat, or worse, pitched toward the flue, holds water on top of your chimney. Every repair we do leaves the crown sloping away from the flue. That slope is what keeps the water moving off instead of in.

Chimney Repair Companies

Chimney Repair Companies in the Triangle come in a few varieties, and choosing the right one matters more than most homeowners realize. You want a company that does chimney work as its main trade, not a roofing or handyman crew that adds chimney work on the side. You need someone who carries professional-grade materials, can explain what they found with camera evidence, and will put a written price in front of you before starting. Durham Chimney Sweep fits that description: we work with DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, and we repair what we find, so you don’t need a second company for the liner, crown, or flashing after a sweep. As a full-service chimney company, we handle repair and cleaning together. Typical repair work covers the range we’ve listed on this page; the written estimate sets the final price.

Questions Worth Asking

Ask whether the company does chimney work exclusively, what brands they install, and whether the estimate is written before work begins. A technician who can’t answer those specifics is probably not the right one. We welcome the questions.

Why Camera Evidence Matters

A chimney problem you can’t see is a chimney problem you have to take on faith. We show the footage. You should never authorize liner or masonry work on someone’s word alone, ours included.

Chimney Masonry Repair

Chimney Masonry Repair covers the brickwork and mortar of the chimney itself, from the firebox up through the stack. It’s needed when mortar joints have weathered away, bricks have spalled or cracked, or the masonry has separated from the flue. In Durham’s climate, the combination of humid summers and occasional hard freezes works mortar loose over time, and repointing before it gets worse is far cheaper than rebuilding. We repoint joints, replace damaged brick, and match materials to the existing chimney so the repair doesn’t stick out. Masonry repair typically runs $500-$2,500 or more depending on the extent of the damage and how high up it goes. We check the full stack during a sweep, and we’ll tell you when a repair can safely wait.

Repointing vs. Rebuilding

Repointing replaces the mortar between sound bricks and preserves the chimney’s structure. Rebuilding means taking the top down and starting over. Most chimneys don’t need a rebuild. We’ll show you which parts of the stack are actually failing.

Matching Old Brick and Mortar

Older Durham chimneys have brick and mortar that don’t match anything at the hardware store. We match the color and hardness as closely as possible, because a mortar that’s too hard can damage softer old brick. The repair should look right and age right.

Brands We Service

We work with a short list of brands we know well, and that matters when it comes to getting the right part for your chimney. Olympia Chimney makes caps and venting components we install regularly, and we know which of their caps suit the flue sizes we see in Durham’s older homes. DuraFlex flexible liners are a staple of our relining work, and we’re comfortable installing them in flues that other crews pass on. We also work with Famco and Copperfield on caps and related components. These are the brands our technicians are trained on, and that training is why we can match a part to your chimney the first time.

Whether you have a DuraFlex liner already in place or an Olympia Chimney cap we replaced last season, we can inspect and service it. Our whole focus is flue health and fire safety, so we don’t spread our work across unrelated trades. If something is worn or failing, we’ll tell you and show you. Whether you have Olympia Chimney, Famco, Copperfield, DuraFlex, or any other make, we can help.

Signs You Need a Pro Right Now

• Water stains on the ceiling or walls near the chimney. That water is coming from the roof, the flashing, or the crown. It won’t stop on its own, and it soaks into framing and masonry as it spreads. A free inspection finds the source before the damage gets expensive.
• White chalky stains on the brickwork. That’s efflorescence, a sign moisture is moving through the masonry from inside. It often points to a failed crown or flashing. It’s worth catching before the mortar starts going with it.
• Crumbling mortar joints between bricks. Once the joints soften and fall out, the bricks themselves start to shift. Repointing at that stage is a modest repair. Rebuilding a leaning stack is not.
• A cracked or missing chimney cap, or one that’s visibly loose. An open flue welcomes rain, animals, and debris. A loose cap can grind against the crown and make a small problem bigger.
• Smoke in the room or a draft that’s gotten weak. A blocked or damaged flue can push smoke back into the house. That’s a sign the chimney isn’t venting, and it needs a professional look before you light another fire.
