The Importance of Chimney Relining

Your liner is one of the most important part of your chimney. The liner has many important jobs, and it requires regular maintenance to function properly. When your liner wears out, it requires professional repairs or even a relining to restore it. However, in order to find the damage you must stay on top of your routine chimney inspections.

Common Liner Damage

The Importance of Chimney Relining - Chesapeake VA - Magic SweepChimney liners become damaged over time with worn out clay tiles, crumbling joints, and deteriorated lining systems. Animal intrusion, creosote buildup, and water damage are the most common causes of liner damage, and our chimney sweeps are experienced in diagnosing and repairing these problems.

Many older masonry chimneys have old and deteriorated clay tiles, and they may not have a liner at all. When this is the case, the system need to be relined. In some instances, the liner just needs minor repairs. It’s important to hire a professional for these repairs, and they can fix it swiftly and correctly.

Why Repair the Liner

Your chimney liner has an important job to do. It protects the house from heat that can weaken adjacent woodwork to cause an accidental fire. It protects your masonry from corrosive byproducts that can shorten the life of your chimney, drop its efficiency, and raise fire risk. A correctly-sized liner provides the flue with optimum airflow, efficiency, and safety. A relining is especially essential after a new installation to ensure the flue is the right size for new capacity.

Relining with Magic Sweep

In the past, the best solution for chimney relining is to pull the old liner out and replace it completely with a stainless steel liner. Stainless steel is the best option due to the durability, and it is safe for use with all fuel types. Because of the durability and dependability of stainless steel, they are the only liner with a lifetime warranty. The downside of stainless steel is the cost.

However, we do have other options as well. Our cast-in-place liners allow our customers to pay less money and get the same protection. If you’re interested in a cast-in-place liner, you should schedule a level two inspection right now with our chimney experts. Call Magic Sweep at 757-523-2400. Are you a realtor or property manager?

Chimney Relining

Over the years, your chimney liner suffers from damage, and this can lead to some serious safety issues. According to the Chimney Safety Institute of America (CSIA), your chimney liner serves three important functions. It protects the bricks and mortar of your chimney from the corrosive gases from combustion, it protects your home from extreme heat transferring to combustibles, and it provides a correctly-sized flue for your heating appliance. If your chimney liner is damaged, it cannot do its job properly. Magic Sweep offers chimney relining services for every type of chimney liner, and we would like to tell you about the options we provide.

If you have an older masonry chimney, you probably have a clay tile liner. Even though these liners are durable and built to last for years, the clay tiles can still suffer from erosion and spalling damage. Magic Sweep offers an economical and easy way to reline clay tile liners with HeatShield. Our chimney technicians have been trained to apply this cerfractory formula with special tools to repair and restore clay tile liners.


The only liner that carries a lifetime guarantee, a stainless steel chimney liner is the best option if your old liner is beyond repair. It is also the easiest way to bring an old chimney up to modern building codes that require every chimney to be lined. You should also choose a stainless steel liner if you are updating your old fireplace with an insert. Magic Sweep can fit the liner to your new heating appliance to give it a properly-sized flue so that the insert will work safely and efficiently.


This type of liner is a lightweight cement-like product that we can pour into your chimney to form a passageway that is smooth, seamless, and insulated. Magic Sweep uses Supaflu Chimney Systems as our cast in place method, and this durable liner comes with a great warranty. We can let you know if this type of liner is an option for your chimney after we perform a Level 2 chimney inspection to see exactly how damaged your flue is.

In order to work at its safest and most efficient level, your chimney needs to be relined when the liner is damaged. Contact us at Magic Sweep to talk to us about which type of chimney relining method is best for your chimney.

Options for Relining Your Chimney

One of the most essential parts of your chimney and venting system, a chimney liner protects your house from heat transfers to combustibles, protects the masonry work of your chimney from the corrosive byproducts of combustion, and provide a correctly sized flue for your heating appliance. Over time, your liner begins to deteriorate and crack, which can cause a couple of hazards. Toxic gases like carbon monoxide can leak through the cracks into your home, and your home is at a higher risk for a devastating chimney fire due to the lack of protection from the high heat that passes through your chimney. If your chimney liner is damaged in any way, it is time to reline your chimney, and Magic Sweep has a couple of options for relining your chimney. We would like to tell you more about our two options to help you decide which one is best for you.

Stainless Steel Liners

The only chimney liner with a lifetime guarantee, a stainless steel liner will never have to be replaced. Since stainless steel is resistant to rusting and corrosion, you will not have to worry about cracking and other deterioration. The liner is sealed from the top to the bottom, which means smoke, gases, and vapors exit your chimney without ever touching the masonry work of your chimney. Another plus of stainless steel liners is they can be insulated. An insulated liner further protects you from creosote accumulations because the combustion byproducts are kept hot throughout the chimney. Additionally, when you are not using your fireplace, the insulated liner will keep cold downdrafts from entering your home through the chimney. Easier to clean and to install than other liners, a stainless steel liner will improve the energy efficiency of your heating appliance by reducing cold downdrafts and by improving your chimney’s draft as hotter gases draw better than colder ones. A good draft contributes to higher fuel efficiency because the combustion process is more complete. If you need to completely replace your liner or if you are building a new home and need a chimney liner, Magic Sweep highly recommends installing a stainless steel liner.

Cast In Place

If you have a clay chimney liner that needs restoring, you have the cast in place option, a technique that pours and casts a lightweight cement-like product into your chimney and is directly applied and formed to restore your clay liner. At Magic Sweep, we use the Supaflu Chimney Systems cast in place liner method because of its high quality and limited lifetime guarantee. Benefits of this type of liner include improved stability of its structure, easy maintenance, suitability to every fuel type, improved efficiency, and added safety. If this type of liner interests you, Magic Sweep will first do a Level 2 inspection of your chimney to assess the liner damage to see if we can do a cast in place restoration or if you will need to replace the entire liner.
