Chimney Cap Installation in Boston, MA

You got an open chimney? Congratulations. You're paying for rain damage you didn't even know you had. Every winter, Boston homes get soaked from the inside out. Snow melts, water drips down the flue, cracks the liner, rots the firebox, and turns your basement into a swamp. Most folks wait till their drywall caves in before they call. We're Roofing & Siding of Cape Cod — the crew that's been fixing chimneys in MA for decades. Licensed. Insured. Veteran-owned. No guesswork: we measure, we fit, we install.

What a Chimney Cap Does — and Why Boston Homes Need One

A chimney cap is a lid. That’s it. In Boston that lid is the only thing stopping rain, snow, and a whole family of raccoons from moving into your flue. You think your fireplace’s closed for the summer? Moisture is still creeping down. Creosote is building. Masonry is slowly falling apart. And when the next nor’easter hits your chimney’s going to leak. Without a cap water damage ain’t just possible — it’s guaranteed.

Chimney Cap Types We Install in Boston

We don’t sell no low-quality caps off a pallet. Here’s what we actually install:

Single-flue chimney cap: One flue, one cap. Stainless steel or copper. No rust — no problems.
Multi-flue chimney cap: Got two flues? One furnace, one fireplace? We weld a custom cover that seals them both.
Custom chimney cap: If it’s an old brick chimney, or if it has an unusual shape, we make a custom cap for it. No off-the-shelf ones.
Top-sealing damper cap: This one seals tight when you ain’t using it. Cuts your heat bill and keeps the cold out.
Chase cover: We cap the whole top for prefab chimneys. No gaps, no leaks.

Stainless steel is tough as nails. Copper lasts for decades and more. These two options are perfect for Atlantic weather.

Our Chimney Cap Installation Process

We come to your house. No extra phone calls, no guesswork. We look at the flue of your house. We measure it and check the crown. See if any bricks cracked.

Then we pick the cap. Not the one that maybe should fit alright. We pick the one that will fit perfectly. Then we install it with stainless bolts and with sealant that won’t crack when it’s 20° below. We don’t just nail it on — we engineer it.

After that we clean up. No debris on your roof, no screws left in your yard. We leave it better than we found it. We don’t do “good enough” — we do it Massachusetts winter-proof.
