- Clean • Safe • Reliable • Done Right
A complete fireplace and chimney restoration paired with a professional wood stove insert installation – rebuilt from the firebox up for safe, efficient, worry-free heat that will last for years to come.
The homeowner wanted the comfort, efficiency, and lower heating costs that a modern wood stove insert delivers – but the existing masonry fireplace simply wasn’t ready to support one. Before any appliance could be installed safely, the entire system needed to be brought back to sound condition.
Our inspection found several issues working against each other. The firebox had deteriorated mortar joints and loose, spalling brick that could no longer handle sustained high heat. The smoke chamber above it was rough, corbelled, and unsealed, creating turbulence that hurts draft and lets creosote build up faster. On top of the chimney, a worn crown and a failing cap were letting water, debris, and animals into the flue – accelerating damage with every freeze-thaw cycle.
Installing an insert over a compromised system like this would have trapped hidden problems behind a brand-new appliance. The right move was to restore the chimney completely first, then install the wood stove insert the correct way.
We treated this as a full-system restoration rather than a quick swap, rebuilding the chimney from the firebox up so the new insert would sit on a safe, code-conscious foundation.
First, our masons repointed and rebuilt the firebox, replacing damaged brick and tuck-pointing the joints with high-heat refractory mortar rated for direct flame contact. Next, we parged and smoothed the smoke chamber, sealing the rough masonry into a clean, streamlined transition that improves draft and makes the flue far easier to keep clean. We then rebuilt the chimney crown to shed water away from the masonry and fitted a new stainless steel chimney cap to keep out rain, downdrafts, and animals for good.
With the structure sound and the flue protected, we professionally installed and connected the wood stove insert – setting it properly, sealing the surround, and verifying clearances and draft so the finished system burns cleanly, safely, and efficiently.
The finished result is a beautiful, fully functional wood stove insert set into a restored brick fireplace – delivering clean, efficient, radiant heat that warms the room quickly while using less wood.
Just as importantly, everything behind the appliance is now solid. The rebuilt firebox, parged smoke chamber, new crown, and stainless cap give the homeowner a chimney that drafts better, resists water damage, and stays cleaner between sweepings – which means safer fires and lower long-term maintenance.
It’s a great example of how we approach every project at TopDog Chimney: fix the system first, install it right, and leave the homeowner with heat they can count on for years.

In most cases, yes. A wood stove insert vents into a chimney that was usually built for an open fireplace, so a correctly sized stainless steel liner is normally required to vent it safely and efficiently. As part of the project we assess the flue and install the right liner so the insert drafts properly and meets code.
A wood stove insert sits inside your existing masonry and depends on it. If the firebox, smoke chamber, crown, or cap are damaged, those problems stay hidden behind the new appliance and can affect safety and draft. We restore the masonry first so the finished installation is safe, sealed, and built to last.
Significantly more. An open masonry fireplace sends most of its heat straight up the chimney, while a modern wood stove insert is a sealed, high-efficiency appliance that radiates far more heat into the room from the same amount of wood - so you stay warmer and burn less firewood.
It depends on the condition of the existing chimney. A straightforward insert installation can be completed quickly, while a full restoration - firebox repair, smoke chamber parging, crown rebuild, new cap, then the insert - typically takes a few days. We give you a clear timeline and written scope before we start.
Yes. TopDog Chimney handles the entire project in-house - masonry repairs, liner, crown and cap work, and the wood stove insert installation and connection. One team, one point of contact, and a chimney system that is restored and installed correctly from top to bottom.
