Hire Us for Chimney Relining & Liner Repair Services

Your chimney liner is one of the most important components of your fireplace system, ensuring your home and chimney stay better protected with every fire you light. In fact, if your liner is outdated, damaged, or incorrectly fitted, you could wind up facing some serious risks, like fire hazards in your home, carbon monoxide exposure, smoke leaks, and more.

The good news for homeowners in Wilmington and its surrounding areas? Old, damaged chimneys can often get the safety and efficiency update they need with a simple relining or repair of the existing liner – and we’re here to help with these services. Give us a call at 410-424-5532 or get your next appointment started right here online.

What Are My Chimney Relining Options?

The chimney technicians at Ace Chimney Sweeps, Inc. are available to reline gas and oil stoves and fireplaces, as well as wood stoves. We use stainless steel liners on most of our chimneys, though we also sometimes recommend using HeatShield® Cerfractory Flue Sealant, which allows us to restore clay flue liners and saves you the expense of rebuilding or relining with a stainless steel chimney liner.

What is HeatShield®?

Older chimneys lined with clay or terracotta are often best treated with the HeatShield® process. This repair system eliminates the hazards and draft problems caused by gaps, cracks, and spalling in otherwise sound masonry chimneys by filling in all openings with HeatShield’s special sealant. Ask us if this could be a good option for you.

Why Are Chimney Liners Important?

We often get asked why a chimney needs to be lined, especially since it hasn’t always been required. Unfortunately, even though codes and standards mandate that all chimneys now be lined, many chimneys today still operate without a liner.

However, it is never safe to use an unlined chimney or a chimney with a damaged liner.

And don’t just take our word for it…

  • The Chimney Safety Institute of America (CSIA) states that problems such as gaps, cracks, and spalling in your chimney’s flue can present serious risks to your home and family because your chimney can no longer perform its intended function – which is to safely contain and vent the products of combustion outside of your home.
  • Building codes and fire standards require that chimneys be structurally sound, durable, smoke tight, and capable of completely and safely moving flue gases outside.
  • The National Fire Protection Association (NFPA) 211 reads in part, “If the flue liner in a chimney has softened, cracked, or otherwise deteriorated so that it no longer has the ability to contain the products of combustion (i.e., heat, moisture, creosote, and flue gases), it shall be removed and replaced, repaired, or relined…”

Luckily the chimney industry has now embraced chimney video scanning to give homeowners a better look at the hidden parts of their chimneys. If we think your chimney needs to be relined, the inspectors at Ace Chimney Sweeps, Inc. are able to use the Chim-Scan system to show you why.

During our chimney inspections, we often find chimneys with eroded or deteriorated clay mortar, cracked flue tiles, or damage caused by chimney fire, water damage, and lightning strikes or settling. Because much of the chimney is hidden from view – including the entirety of the chimney’s lining – you may not see why your chimney needs to be relined until the symptoms manifest themselves in very obvious ways. This is why booking regular maintenance professionals is such a must.

Can You Reline an Old Chimney?

We take great pleasure in making upgrades to older chimneys and in replacing or repairing deteriorated liners. We feel better knowing that, after we’re done, you and your family are safer because your chimney won’t be putting you at risk of a house fire or carbon monoxide poisoning.

With nearly 40 years’ experience in the chimney business, those of us at Ace Chimney Sweeps, Inc. have seen the aftermath of horrific house fires that were caused by chimneys in disrepair. Trust us, and don’t take chances with your home or your family. Our recommendations will always be about keeping your family as safe as possible.
