The Benefits Of Refractory Mortar

Did you know your fireplace and chimney may be constructed using only standard bricks and mortar? However, today’s chimney professionals know that there are benefits to choosing refractory materials for fireplaces and chimneys. More than that, it’s required by the International Residential Code (IRC) and the International Building Code (IBC).Benefits Of Refractory Mortar - Suffolk NY - Chief Chimney Services

Safety First

If you choose an amateur to build or repair your firebox, he may cut corners and costs by failing to use the right materials! This is a dangerous hazard and will result in damage to the masonry and heat transfer to the structural materials of the home. It also lowers efficiency and increases fire risk. Whats else happens if refractory mortar isn’t used, along with fire bricks? There will be recurring damage, which an amateur or con artist may repeatedly repair. This can end up costing you a fortune. A certified chimney sweep who is trained in masonry construction and repair knows the necessary materials to help keep customers safe this winter.

Choosing the Right Professional

When you choose a professional to complete your chimney and fireplace rebuilds and repairs, you can rest assured that they know what they’re doing. A CSIA Certified Chimney Sweep® (CCS) will use the proper materials that will offer the safest and most efficient fireplace and chimney system. Chief Chimney Services has been operating in Suffolk County for over 20 years! We are aware of municipal codes and industry standards. In addition, we’ve acquainted with general contractors in the area who often work with us.

Using the Wrong Mortar

Using the wrong materials when building or repairing a chimney can mean a devastating fire. Don’t hire a chimney sweep who is inexperienced and uses incorrect materials! Doing so may result in your homeowners insurance having grounds to deny your claim in the event of a fire. Some professionals may cut corners by adding fire-clay to regular mortar. This is not recommended and does not get the same result. Only a refractory mortar, designed to be as strong as fire brick and flue tiles, can withstand the regular high temperatures and abuse of a fireplace and chimney.

Some professionals and homeowners alike think it’s okay to use standard mortar mix, if you only use the fireplace occasionally. This is precisely why it is against residential and building codes! If the home is sold or property is otherwise transferred, the new owner is stuck with the unsafe chimney. Perhaps they will want to light a fire every night, instead of only occasionally. This puts people at risk that can be avoided.

Do you think your fireplace or chimney was constructed or repaired improperly? There is still time to have it inspected by a CSIA certified professional before winter! A Chief Chimney technician can quickly assess your chimney system for problems and plan accordingly. Our sweeps are standing by to talk to you about refractory mortar and more.

Masonry restoration is the phrase used for working with any form of masonry on an existing building or home that doesn’t encompass actually building it. Restoration runs the gamut from tearing the masonry down and rebuilding it from scratch to cleaning and sealing. One of the most commonly needed restoration projects is masonry and firebox repair. Keep reading to learn what this job involves and why it’s so critical.

Masonry and Firebox Repair

The specific type of mortar used in fireboxes is called refractory mortar. However, don’t assume that your fireplace was built with this mortar. The chances of an older home actually having refractory mortar in the firebox are slimmer than the chances of a newer home. This is due in large part to changing building codes and the availability of the product. Many brick masons who constructed fireboxes in homes well into the 1990s used either a Portland-cement-based mortar or a self-concocted fireclay mortar (a mix of Portland cement, crushed fireclay, and sand).

Although both of these mortars were approved by building codes of the time, they haven’t fared well in homes in which the fireplaces are used regularly; the problem is simple: Portland cement doesn’t hold up well when subjected to the cycle of heating and cooling that occurs in a firebox. In an effort to combat this problem, most major building codes have added clauses requiring refractory mortar be used, as it doesn’t use Portland cement as a binder; instead, either calcium aluminate or sodium silicate is the binder. Over the long haul, refractory mortar performs far better than Portland-cement mortar and is more readily available than it was a few decades ago.

Approaches for Repairing a Damaged Firebox Mortar

In order to repair damaged firebox mortar, you can take one of three approaches. The first approach involves simply scraping out and repointing the joints between the bricks with refractory mortar. The second approach involves applying a thin coat of refractory cement over the floor of the firebox. The final approach involves removing damaged bricks and replacing them with castable refractory cement. No matter which approach is taken, scrubbing the surface clean and vacuuming any dust before making the repair is critical.

Along with any part of your home, your fireplace requires maintenance to ensure your family’s safety during its use. A damaged firebox can be a potential fire hazard and should be repaired or replaced before using the fireplace again.
