Attractive green spaces, well-maintained parks, an abundance of outdoor recreation opportunities, and proximity to major highways make Shrewsbury a popular place for both locals and visitors. However, local weather conditions in our Central Massachusetts area with below-freezing winters followed by wet and humid summers are particularly tough on masonry chimneys, making annual inspections and timely repairs essential. Homeowners in Shrewsbury and surrounding towns appreciate the prompt, accurate, and reliable repairs that Horizon Chimney Services offers.
Common Chimney Repairs in Worcester County
The extreme temperature shifts and heavy precipitation common here can accelerate the deterioration of masonry chimneys. Horizon Chimney Services specializes in addressing these and other issues to ensure the structural integrity and efficiency of your chimney and attached heating appliances.
Tuckpointing
Just like the filling in a layer cake, mortar holds bricks together. Mortar joints are particularly susceptible to cracking, especially when exposed to frequent precipitation and freeze-thaw cycles. When the mortar deteriorates, tuckpointing— the process of replacing damaged mortar joints with a fresh bonding compound—is essential for restoring the chimney's strength and preventing further water damage.
Chimney Cap Replacement
The chimney cap is the first line of defense against the elements of Mother Nature. When the cap is damaged, loose, or missing, rain, snow, debris, and animals can enter the flue. It can lead to water damage, flue obstructions, and rust. Replacing the cap is a simple and cost-effective way to prevent significant and costly damage to the chimney’s interior components.
Chimney Crown Repair/Rebuilding
The chimney crown is the concrete surface at the very top of the chimney, covering the exposed flue pipe. Its sloped design and drip edge direct water away from the stack. When cracked or damaged, rain, snow, and debris can seep inside the structure. Depending on the extent of the damage, our certified technicians will either apply a sealant to repair surface cracks or rebuild the crown.
Flashing Repair
Flashing is the sheet metal that is installed to create a watertight seal where the chimney meets the roofline. Improperly installed, damaged, or rusted flashing is a leading cause of roof and attic leaks. Repairing or replacing damaged flashing is vital to preventing a leaky chimney.
Signs Your Chimney Needs Repair
Homeowners in Shrewsbury, MA, should be on the lookout, especially after a significant weather event, for these signs that indicate a chimney repair may be necessary:
- Deteriorating Mortar: Noticeable flaking, crumbling, or holes in the mortar joints.
- Spalling Bricks: Bricks that are flaking, peeling, or popping off the chimney surface.
- White Stains (Efflorescence): A powdery white deposit on the exterior masonry, which indicates that brickwork is absorbing moisture.
- Rust: Rusting or corrosion on the damper or metal components inside the firebox.
- Water Stains: Stains on the chimney chase, walls, or ceiling near the fireplace.
