Fireplace Repair Services in Westchester County

A fireplace that won't draft, a damper that won't budge, or a firebox with crumbling joints isn't just frustrating — it can be genuinely unsafe to use. Heat, moisture, and years of fires take a toll on every working part of a fireplace, and once components begin to fail, the problems tend to compound. Professional fireplace repair from Westchester Chimney Pro restores your fireplace to safe, efficient operation, whether it needs a new damper, a rebuilt firebox, fresh refractory mortar, or a set of glass doors.

Our technicians work on masonry and prefabricated fireplaces alike, diagnosing the real cause of the problem before recommending a fix. We don't push unnecessary work — if a simple repair will do, that's what we'll suggest. But when a component is unsafe, we'll tell you plainly and explain your options. Below are the most common fireplace repairs we perform and the signs that tell you it's time to call.

Common Fireplace Repairs We Perform

Damper Repair & Replacement

The damper seals your flue when the fireplace is idle and opens to vent smoke when you light a fire. Over time, dampers rust, warp, lose their seal, or seize up entirely — wasting heated or cooled air and, in some cases, trapping smoke and gases in the home. We repair sticking dampers and replace failed ones, including installing energy-efficient top-sealing dampers that close off the flue at the very top for a much tighter seal.

Firebox Rebuilds & Refractory Repair

The firebox endures the most intense heat in your fireplace, and the firebrick and refractory mortar that line it eventually crack and deteriorate. Damaged firebox panels can expose the surrounding structure to heat, which is a serious fire risk. We repoint deteriorated mortar joints and rebuild fireboxes with proper high-temperature firebrick and refractory materials, restoring both safety and appearance.

Glass Door Installation

Fireplace glass doors improve safety by containing sparks and embers, boost efficiency by reducing heat loss up the flue when the fireplace isn't in use, and add a finished look to your hearth. We supply and install glass doors sized and fitted to your fireplace, and we replace cracked or damaged doors on existing units.

Repointing & Masonry Repair

Just like the chimney above it, the masonry in and around your fireplace can develop failing mortar joints and cracks. We repoint and repair this masonry to keep the structure sound. For damage that extends up the chimney itself, our chimney repair team handles tuckpointing, crown work, and structural restoration.

Signs Your Fireplace Needs Repair

• A damper that's stuck open, stuck closed, or won't seal
• Cracked or crumbling firebrick or mortar joints in the firebox
• Smoke spilling into the room instead of drawing up the flue
• Rust on the damper, firebox, or surround
• Gaps or cracks between the firebox panels
• A drafty fireplace that lets cold air in when not in use
• Cracked, foggy, or broken glass doors
• Pieces of brick or mortar found in the firebox

If your fireplace is drafting poorly or smoking, the cause may also lie in the flue — a chimney inspection helps us pinpoint whether the issue is in the firebox, the liner, or the chimney structure.

Our Approach to Fireplace Repair

We start every repair with a careful evaluation of your fireplace and venting system, because a smoking fireplace or a draft problem can have several possible causes. Once we've identified the real issue, we explain it clearly, provide a written estimate, and complete the work with quality, code-appropriate materials. Whether it's a quick damper fix or a full firebox rebuild, our goal is the same: a fireplace you can use safely and enjoy for years to come. Many customers pair a repair with a fireplace cleaning so everything is fresh and ready for the season.
