Chimneys are complex structures, and cleaning and maintenance are critical for proper exhaust venting and top-notch performance. You may not be able to see it, but over time, a residue known as creosote builds up inside the chimney, especially when wood is burned. Creosote is highly flammable, and if not cleaned regularly, it can cause dangerous chimney fires that threaten your home and family. Even if your fireplace is unused, professional chimney cleaners ensure that the chimney is free of blockages, such as bird nests or debris, which could obstruct the chimney from properly functioning. Blocked chimneys can lead to poor ventilation, resulting in a dangerous buildup of carbon monoxide in your home—a potentially deadly hazard.
A thorough inspection can reveal early signs of structural damage. Many chimney services now use advanced tools to inspect the inside of chimneys, providing a detailed assessment of their condition in the nooks and crannies that would otherwise remain unseen.
Areas of a chimney exposed to the elements are more prone to deterioration. Rain, hail and snow can erode the mortar between bricks, allowing water to penetrate and cause further damage. Water seeps into the bricks and the mortar expands and contracts with temperature changes. This freeze-thaw cycle can lead to cracking, crumbling, and even spalling, where pieces of brick break off. Regular inspections and routine cleanings help spot small issues before they become major problems. Once identified, these issues can be repaired by a historic brick expert to ensure the long-term stability of your chimney.
Not all brickwork is created equal, and that’s especially true for chimneys in historic homes. Using modern materials, like cement-based mortar, on a historic chimney can accelerate damage. Modern mortar is much harder than the lime-based mixtures used in older homes and can put too much pressure on the softer historic bricks, leading to cracking and crumbling over time.
A historic home expert will ensure the original mixture is used for repairs. Using traditional tuckpointing, the team of expert craftspeople can repair damaged mortar and replace it with the appropriate lime-based mixture. This method ensures that the repairs are both historically accurate and durable.
By using the right materials and techniques, historic brick experts not only preserve the structural integrity of your chimney but also help maintain the architectural character of your home. When repairs are combined with professional cleaning, you can relax by the fire, knowing your chimney is efficiently and safely working all winter long.
