- Clean • Safe • Reliable • Done Right
Water is the single biggest enemy of masonry. We apply breathable waterproofing that blocks rain, snow, and ice penetration while letting your chimney breathe – adding years of life to the structure.
Water damage is the underlying cause of most chimney problems – spalled brick, failing mortar, cracked crowns, interior leaks, attic stains. Proper waterproofing dramatically slows or prevents most of these by keeping moisture from entering the masonry in the first place.
Done at the right time, with the right product, on a chimney in good condition, waterproofing extends the life of the structure by decades and protects every other repair you’ve already invested in. It’s one of the most cost-effective protective measures available.
We treat your home like our own – careful, clean, and respectful, especially around kids, seniors, and pets.
Fully credentialed technicians on every job.
Comprehensive coverage for total peace of mind.
A decade of chimneys done right.
Clean methods, safe air for everyone at home.

Proper waterproofing is a process, not a paint job. Here’s exactly what we do.
We check the chimney for any damage that should be repaired before sealing – a sealed chimney with cracks is a sealed-in problem.
Crown cracks, failing mortar, or damaged brick fixed first.
Breathable masonry waterproofing applied in proper conditions with full coverage of all exposed surfaces.
The product cures over 24–48 hours, after which the chimney is fully protected for years.

Brick and mortar are porous like a sponge. Waterproofing protects them from absorbing rainwater, which freezes, cracks, and destroys the structure.
Not our solution. We use professional-grade, breathable water repellents that seal out moisture completely while remaining 100% invisible.
Our premium waterproofing treatments typically protect your brickwork and prevent water entry for up to 5 to 10 years.
Chimney waterproofing applies a breathable sealant to the masonry that blocks water absorption, leaks and freeze-thaw damage while letting the chimney breathe — for homes across Greater Boston. Call (781) 782-8727.
