From Minor Fireplace Fixes to Major Chimney Restorations, We Do It All

We like to consider ourselves a one-stop shop for chimney repair services. Our comprehensive range of repairs ensures that all your chimney needs are met under one trusted roof. This includes:

Chimney Rebuilds

Chimney rebuilds involve the complete reconstruction of a chimney structure. This is typically due to extensive damage, structural instability, or the need for a significant upgrade – all of which are instances where repairs alone can’t effectively address the issues. 

During a chimney rebuild, we dismantle the old chimney (or part of it), and construct a new one from the foundation up. When the new chimney is complete, we can ensure not only its safety and stability, but also its compliance with building codes and standards. We build chimneys to last for years to come.

Chimney Masonry Repair

When a chimney has suffered from wear, weather damage, or deterioration over time, chimney masonry repair services are often needed. This repair process typically addresses issues like cracks, loose or missing bricks, and crumbling mortar joints. 

Masonry repair is not only important in maintaining the structural integrity of the chimney, but to also prevent further damage, water penetration, and potential safety hazards. Because of this, we offer a long list of masonry repair services, including tuckpointing, brick replacement, and the previously mentioned chimney rebuilds when necessary. 

When repairs are complete, we will recommend waterproofing your chimney – a service that involves applying a protective sealant to the exterior of your chimney to enhance its durability and reduce the risk of damage down the line.

Chimney Relining

A chimney liner, often referred to as a flue liner, is an essential component of your chimney. It provides a proper channel for smoke and gas to safely exit your home, while preventing those harmful combustion byproducts from entering back into your living space. When a chimney liner has deteriorated or isn’t fitted correctly, the risk of fire hazards, toxic gas exposure, and structural damage to your chimney and home increases significantly. That’s why chimney relining services are a must.

HeatShield® Repair & Resurfacing

When it comes to chimney relining, our preferred method is HeatShield® because it provides a reliable and effective way to restore your chimney’s integrity at a price most homeowners can afford. 

There are many methods of relining a chimney. Clay tile liners, metal liners, and cast in place are all effective and safe ways to protect your chimney. However, HeatShield® Chimney Liner Repair Systems have a rather unique installation process that stands out from the other options. Using a foam applicator, we apply a specially formulated Cerfractory sealant to repair and reinforce your existing chimney liner. This innovative approach ensures a smooth, durable finish while minimizing disruption and cost.

Chimney Leak Repair

Water in your chimney can create some major issues. That’s because water causes damage to just about everything it touches – from the chimney’s masonry to every interior component. It can lead to cracks, spalling bricks, deteriorated mortar joints, rusted chimney dampers, and even the growth of mold and mildew. 

If you have any water damage or notice any signs of a leak within your chimney, give us a call right away. Prompt attention to water-related issues is crucial in preventing further and more costly repairs.

Chimney Caps

A small but vital component to your chimney system is the chimney cap. Sitting at the very top of the chimney, these protective covers serve multiple essential functions. They shield your chimney from rainwater (and prevent moisture-related damage), keep out birds and other animals, block debris from flying in, and help contain sparks and embers so they don’t ignite any nearby combustible materials. 

Chimney caps are a simple, yet effective way to reduce your risk of chimney fires and roof damage while also extending the lifespan of your chimney.

Who Should You Call For Chimney Repairs & How Do You Know What Really Needs To Be Done?

First things first, who should you call? There are no federal regulations for the chimney industry, and many homeowners have been ripped off, cheated, scammed, or left with workmanship that’s not up to code and certainly not safe. The Chimney Safety Institute of America (CSIA) is a non-profit organization that’s committed to educating and protecting homeowners for this very reason.

That’s why the CSIA developed a certification process for chimney professionals. In order to receive the certification, the chimney technician has to demonstrate extensive knowledge, pass rigorous testing, and agree to do his or her job with integrity. That’s why the CSIA is able to guarantee that homeowners are in better hands with a CSIA-certified chimney professional. 

So when you’re looking for someone to repair your chimney — whether you need masonry work, chimney liner repair, or chimney leak repair and prevention — the first thing you should do is check the credentials of the chimney companies you’re looking at. For your safety and satisfaction, go with a CSIA-certified chimney sweep.

How Do You Know If Your Chimney Needs To Be Repaired?

Here are a few common signs that can signal problems with your chimney system:

  • Bad odors. Odors in the chimney are usually caused by creosote or nesting animals. Both will need to be removed and repairs may need to be made.
  • Smoke problems. Your fireplace really shouldn’t be putting smoke back into your home, so if it is, there’s a problem. There could be a flue blockage or your chimney may not be achieving proper draft. Either way, you’ll need to have the chimney looked at so a solution can be found.
  • White staining on your brick. White stains on your brick signal one thing: excess water. Excess water will lead to chimney leaks and masonry damage, possibly even chimney collapse. So at the first sign of white staining, it’s important to discuss waterproofing solutions with an experienced chimney professional.
  • Cracked firebox. The panels in your firebox, the area of your fireplace that holds the logs, can crack as a result of wear and tear or moisture exposure. And when this happens, repairs need to be made to prevent high heat, hot ash, and CO from getting into those cracks and causing problems.
  • Rust on your chimney, chase cover, or chimney cap. You should never see rust anywhere on your chimney — not on your chase cover, not on your chimney cap, not on your flashing, and not on your chimney chase. If you do, something needs to be replaced ASAP to keep water from getting into the system.
  • Flaking or deteriorating brick and mortar joints. Moisture can cause the brick of your chimney to flake (spall) or deteriorate, and the mortar joints between your brick to erode and recede. To keep your chimney standing strong and free of leaks, you’ll need to have any damaged brick and mortar joints repaired promptly.

Dealing With Chimney Damage: What’s the First Step You Should Take?

Whether you have a general idea of what needs to be fixed or you’re not sure what’s going on, you just know something’s not right, the first step is to schedule a level 2 chimney inspection. A level 2 chimney inspection is superior to a level 1 or standard chimney inspection because it will give you a more thorough idea of what’s going on with your chimney. 

How so? A camera will be snaked up into your chimney to get a look at the flue liner, and the exterior of the chimney will be inspected as well. We’ll check for things like leaks, masonry damage, liner damage, missing components, improper installation, insufficient clearance from combustibles, and anything else that could potentially impact the safety or performance of your chimney and fireplace. 

So it doesn’t much matter if you know exactly where the problem is – just start by scheduling a level 2 chimney inspection. We’ll find the issue, then let you know what we recommend. And whatever you need, we’ll take care of it, from masonry repairs and chimney leak repairs to chimney relining or resurfacing to a full-on rebuild.

What Causes Most Chimney Damage?

Most chimney damage is caused by one of the following things (or a combination):

  1. Moisture. Water is the #1 cause of chimney damage, and it’s capable of destroying the masonry and metal components of your chimney system. So every time it rains, sleets, or snows, that moisture is working against your chimney.
  2. Neglect. Chimneys need to be cleaned routinely, especially if creosote is present. Creosote is a highly flammable and highly corrosive substance that can cause chimney fires and wear away at liners. If the chimney is neglected and corrosive flue gases and creosote are left in the chimney season after season, a lot of damage can be done.
  3. Chimney fires. Contrary to what you might think, chimneys are not built to withstand the heat of a fire. In fact, if creosote ignites in the chimney and causes a chimney fire, the liner could collapse or crack in just moments, causing extensive damage.
  4. Severe weather. Tennessee is a great state, but we get some pretty extreme weather. This can include things like tornadoes, lightning strikes, straight line winds, heavy rain, and sleet. All of these things can do a number on your chimney’s exterior.
  5. Animals & birds — Without a chimney cap, animals, birds, and even bats can get into the chimney and set up shop. That doesn’t just mean furry or feathered guests keeping you up all night, it also means bugs, feces, and other unpleasant things that can cause some serious damage to your chimney.

How Can You Prevent Chimney Damage?

There are several simple things you can do to prevent chimney damage:

  1. Only burn well-seasoned wood. Green or wet wood will lead to a greater production of creosote, and creosote can be incredibly dangerous and damaging to your chimney.
  2. Schedule inspections every year, even if you don’t use your fireplace. A lot can happen in a year, and with most of your chimney system hidden from view or high above your eye line, you might not even see what’s going on until things are pretty bad. By scheduling annual inspections, you’ll find out about problems before they have time to worsen.
  3. Invest in a good chimney cap. Chimney caps are covers that go over the chimney top to keep water, bugs, birds, and animals out. If you don’t have a good chimney cap or yours has rusted or blown off, investing in a stainless steel cap with mesh screening can go a long way towards protecting your chimney and preventing damage.
  4. Waterproof your chimney. When the weather’s bad outside, you can go inside for some reprieve. But your chimney’s out in it all day, all night, all year. Temperature changes and moisture from rain, sleet, or snow can cause the masonry of your chimney to crack, flake, crumble, and leak, but waterproofing can prevent all of these things for decades.
