A Somerville fireplace that smells of animal or drips after rain is usually missing the one component that would have stopped both: a proper cap. We size the cap to the actual flue, choose stainless or copper for corrosion resistance, and mount it so wind and weather will not lift it. In area, downdraft complaints spike in winter when wind hits an uncapped flue, and the right cap design steadies the draft. If your crown needs a small repair to anchor the cap properly, we tell you up front rather than mounting onto bad masonry. Call 508-305-7829 to stop rain and wildlife from getting into your flue.

Why It Is Worth Doing Right
Material matters as much as fit. The cheap galvanized-steel caps sold at hardware stores rust through in a couple of winters, especially anywhere near salt air. We install stainless steel or copper, both of which shrug off corrosion and last for decades. The slightly higher cost up front is the difference between a cap you install once and a cap you replace every few years — an easy call once you have seen a rusted-out one.
The MA climate is the single biggest force working against a Somerville chimney. Water gets into the masonry through hairline cracks, freezes overnight, expands, and pries those cracks a little wider — then the cycle repeats with every cold front. Over a few winters that freeze-thaw action turns a minor flaw into spalled brick, an open joint, or a cracked crown. Catching it early is the difference between a small repair and a rebuild.
How We Do It
A good cap does three jobs at once. The top keeps rain off the smoke shelf and out of the flue, where water does the most damage. The mesh sides keep birds, squirrels, and raccoons from nesting in the chimney — nests that block the flue and create a fire hazard. And the spark-arrestor function keeps embers from drifting onto the roof. One properly chosen cap shuts down all three problems simultaneously.
For chimneys with more than one flue sharing a single stack — common on older Somerville homes with a fireplace and a furnace venting through the same chimney — a custom multi-flue cover is the right answer rather than separate small caps. A single fabricated cover protects all the flues, sheds water off the entire crown, and gives the stack a clean finished look. We fabricate and fit these to the specific dimensions of your chimney.
Why Local Experience Matters Here
Because we are based right here and work Somerville and area every week, we know the local chimneys: how the older masonry was built, which crowns were poured too thin, where flashing tends to fail on the rooflines common in these neighborhoods. That local knowledge means a faster, more accurate diagnosis and a repair scoped to what your specific chimney actually needs.
What Is Really at Stake
It is easy to think of a chimney as cosmetic, but every component does a safety job. The liner contains the heat of the fire and routes gases up and out. The cap keeps embers off the roof and animals out of the flue. The crown and flashing keep water from rotting the structure. When any of these fails, the risk is real — fire, carbon monoxide, or structural damage — and that is the stakes we are working with on every job.
There is a right way and a wrong way to run a chimney business, and the wrong way is what has given the trade its bad name — the "$99 special" that becomes a thousand-dollar invoice, the invented emergency, the upsell on a sound flue. Delgado Chimney Care does the right way: honest grading, photo documentation, written quotes, and the freedom for you to say no. We would rather keep a customer for twenty years than win one job today.
Pulling your whole chimney project together
A chimney is a system, so chimney cap installation rarely stands alone — it connects to creosote removal, Level 2 inspection, chimney repair, cracked crown repair, chimney liner installation, and our crew handles all of it under one roof. We bring the same service to Cambridge chimney cap installation, Chimney Cap Installation in Brookline, Chimney Cap Installation in Newton, Chimney Cap Installation in Quincy and everywhere else across the area.
