Masonry building materials naturally deteriorate over time. Repointing can help your chimney look like new. If you have noticed that your fireplace is starting to sag, lean, or lose mortar, you need to have a professional resolve the issue before the problem gets any worse. Repointing will prevent a fireplace from degrading and collapsing.
Chimney repointing is the process of replacing old, failing, or damaged mortar from joints in a masonry fireplace. This is done to strengthen the structure of the chimney and add years to its useable lifespan. We basically scrape out the crumbling material and replace it with specially blended mortar that will match the look of the existing fireplace.
The mortar we use in the repointing process contains certain minerals that will not exceed the brick in hardness. This is important because if the mortar is harder than the brick, then the brick will take the stress during a freeze cycle causing it to chip and break.
Uneven surfaces in your tile or brick flue liner can reduce the efficiency of ventilation and cause hot spots for deterioration. Relining your flue with a stainless steel column is a fast and inexpensive solution to a deteriorating chimney with no expense to its visual appearance. Other benefits of flue relining include:
A liner helps to insulate and protect a home from heat transfer. Whether you have a wood, gas, or oil burning fireplace, a liner insulates and prevents heat from spreading to any combustible materials like wood. The National Bureau of Standards states that unlined chimneys allow for rapid transfer of heat, which can eventually lead to a house fire.
Gases that pass through a fireplace tend to be acidic in nature. These gases degrade brick and mortar, which shorten the lifespan of a chimney. Also, when mortar joints erode, heat can transfer too rapidly. A liner protects a fireplace from abrasive and damaging substances.
Some chimneys double as exhaust systems for dryers, furnaces, HVAC systems, and other appliances. For these appliances to work as efficiently as possible, the flue must be the correct size! A fireplace liner provides a correctly-sized flue for most residential appliances, which can help improve their overall efficiency.
CROWN AND CAP REPAIR
The chimney top, called the crown, is used to direct rainwater away from the fireplace flue. If cracks are found in the crown, it is important to have them repaired right away because they will lead to accelerated deterioration inside the flue and to water leaking inside your home.
Chimney caps have always played an important part in keeping rain and pests out of your fireplace flue. Rain inside your flue will expedite masonry deterioration and lead to costly expenses down the road. Nesting animals can clog your flue and lead to ventilation problems, as well as potentiate a chimney fire.
We can also assist you with residential or commercial damper repair. A chimney damper is essential for individuals who want to maximize their home’s energy efficiency. Dampers are devices for a fireplace that work in a similar fashion to a cork in a bottle of wine or champagne. Much like a cork that stops fluids from escaping a bottle, the damper prevents air from leaving or entering a chimney.
Two types of dampers are available to property owners and our company can repair both varieties. Listed below is some basic information of the two styles of existing fireplace dampers.
- Throat Dampers – They sit above the fireplace opening and tend to be very difficult to replace or remove. This is because a throat damper is set on the top layer of firebrick. Once the damper is set, regular brick is layered above the throat damper’s frame.
- Top Dampers – They are installed on the very top of a chimney, are easier to use, and prove to be less problematic. A top damper is very similar to a chimney cap and prevents water or animals from entering a fireplace.
WATERPROOFING AND FLASHING
Water is the biggest threat to your masonry brickwork. Moisture causes problems with discoloration, chipping, and flaking of the brick, as well as deterioration of the mortar. We can treat all exterior brickwork with special water repellant, which forms a vapor-permeable membrane for the chimney. This membrane allows water vapor to escape the masonry structure and it does not absorb water from heavy rain. This waterproofing treatment will add years to the life of your fireplace.
Additionally, flashing is a critical part of waterproofing a roof. The joint between the chimney and the roof is a common source of water leakage. Without flashing, a fireplace is prone to serious structural damage. If you are noticing water stains on the drywall near your chimney, this is a major sign that water is leaking in.
We can inspect your fireplace to look for loose or missing flashing pieces and examine the chimney below the roofline for any signs of water. Even the strongest flashing materials will wear down and eventually need repair or replacement.
