For most homes in the Merrimack Valley and North Shore, the masonry chimney is the most prominent feature of the house, but also the most vulnerable to water damage. The constant barrage of heavy rain, snow, and our region's continuous freezing and thawing throughout the winter means it is only a matter of time before masonry damage occurs. This damage can lead to costly repairs or even structural failure.
That's why professional chimney waterproofing is a necessary investment for homeowners across Northern MA and Southern NH. It's essential protection that saves you money and prolongs the life of your chimney.
Why Water Is the "Mortar" Enemy of Masonry
Although bricks and mortar are durable building materials that can last for a century or more, they are still porous materials. After years of exposure to seasonal weather changes, they eventually lose their water resistance and begin absorbing moisture like a sponge. Then, when temperatures drop below freezing, the absorbed water freezes. As the ice crystals expand, the immense pressure causes the brick's hard outer shell to flake and the mortar joints to crack. It’s similar to the way a glass filled with water can shatter in the freezer. As this freeze-thaw cycle repeats and the cracks widen, water leaks into the structure, reducing its strength and stability.
Professional Waterproofing vs. Sealing
It's essential to understand the difference between professional chimney waterproofing and sealants.
Waterproofing Sealants
Sealing the brickwork with the wrong type of repellent traps existing moisture within the bricks and mortar. This type of sealing actually worsens masonry damage by preventing the masonry from “breathing.”
Professional Water Repellants
Sweepnman uses a professional-grade, vapor-permeable, water-based solution formulated for waterproofing masonry chimneys. This product penetrates deep into the pores, bonding with the masonry to repel precipitation while still allowing the chimney to "breathe." This vapor-permeable membrane is key, as it will enable any water vapor trapped within the brick and mortar to evaporate while preventing further moisture absorption.
The Sweepnman Waterproofing Process
For best results, our trained masons follow a strict quality control process:
- Inspection: We inspect the chimney for existing masonry damage and clean the surface to remove any dirt or residue that could interfere with the bonding agent.
- Masonry Repair: Any required tuckpointing, crown repair, flashing work, or other masonry repair is taken care of first to ensure the chimney is structurally sound before waterproofing.
- Application: our certified installation crews applies the professional water repellent to the entire exterior masonry surface, ensuring complete coverage.
Benefits of Professional Chimney Waterproofing
In addition to saving you time, money, and frustration dealing with water damage, waterproofing your chimney offers many money-saving benefits:
- Eliminate Leaks: It is the single most effective way to prevent water from entering the masonry structure.
- Prevent Freeze-Thaw Damage: It instantly stops the damaging cycle of water freezing and expanding inside the bricks.
- Reduce Efflorescence: It minimizes the white, powdery stains (efflorescence) that appear on the surface where bricks absorb moisture.
- Extend Chimney Lifespan: Proactive masonry protection significantly extends the life of the entire chimney structure, saving you thousands in rebuilding costs.
