We Specialize in Firebox Repairs & Rebuilds

Your firebox is the part of your heating system that takes the brunt of the heat and does the real dirty work. It’s the part where fires are built and burn, and because of this, it takes on a lot of heat and wear and tear. That’s why it’s important to regularly maintain and inspect it to make sure it’s working efficiently and safely.

And if it’s not? Well, no worries. Our experts are here to help with quality firebox repair and rebuilding services. Give us a call at 206-574-8414 or reach out to us online now.

Common Firebox Damages

So, what are the most common types of firebox damage? And what can our experts do to address them?

Water Damage

Water damage is the number one reason fireboxes need repair. When water leaks into your firebox through your chimney, it can lead to cracks and gaps in the brick and mortar. It can also cause vegetation growth, spalling, and lime leaching, leaving white splotches of calcium deposits all over the surface of the brick. Lime leaching can also take place when water comes into contact with the brick and mortar in your masonry fireplace, which leads to the formation of stalactites.

In addition to the damage that water can do to your firebox visually, it seriously compromises the integrity of the firebox structure, and can significantly shorten its life span. If you’re noticing any of these visual signs of water damage in your firebox, chances are you have a serious leak in your chimney. When a leak is left untreated, it is likely to rot the wood and produce mold in the walls and ceiling surrounding your chimney system. Before we address the spalling or other visually unappealing damage, we will locate the source of the water damage and make the necessary repairs. Once these repairs are made, we can move on to restoring or rebuilding your firebox.

Poor Design and/or Craftsmanship

Not everyone is a skilled mason, and not everyone has the knowledge and experience to design and install a firebox. Maybe you thought you were hiring a professional, but your dream fireplace came out looking like something from a bad “do-it-yourself firebox repair” video. Well, mistakes can happen, but they shouldn’t factor into the safety and efficiency of your chimney and fireplace. Or maybe that beautiful – but somehow unbelievably cheap – stone turned out to be just that… unbelievably cheap.

At Pristine Sweeps, we have a passion for masonry and design and an eye for detail that you just don’t see anymore. We guarantee that your firebox work will be done beautifully and efficiently when you trust our crew.

Prefab Part Replacement

Perhaps you ordered a prefab firebox, and something simply isn’t working properly. We have experience repairing all types of fireboxes, regardless of manufacturer or age. If the parts are still available, then we can fix it.

Often times, the refractory panels in prefabricated units simply become damaged, bent, gapped, or dislodged. We have the tools, training, and expert knowledge to get these replaced, so you can use your fireplace safely and with the peace of mind you deserve.

Age & Natural Wear

Brick and mortar masonry is meant to be durable, but will inevitably crack and crumble over time. This can happen as a result of extremely drastic temperature changes (freeze/thaw cycle), water damage, and improper maintenance. If you notice any cracking or crumbling in your firebox, it is important to have a professional check for possible causes. You may have a leak that is causing extensive damage that you can’t even see.

We’ll find out the issue, make necessary repairs, then implement preventive measures to ensure these problems don’t recur down the line.
