These guys waterproofed my chimney after years of water getting in through the brick. Applied some kind of sealer that lets the brick breathe but keeps water out. David explained the whole process and it's been bone dry since then even in heavy storms.

Had some serious chimney crown damage after last winter's freeze thaw cycle. The concrete was cracking and letting water seep down into the house which was causing stains on the ceiling. Quincy Air Duct, Dryer Vent & Chimney Services came out and rebuilt the whole crown properly with the right slope so water runs off instead of pooling. Looks great now and no more leaks.

What I appreciated most was how they didn't try to upsell me. They found some loose masonry and suggested simple repairs instead of pushing a full rebuild. They fixed the crown, sealed the flashing, and left me with peace of mind.
