Want to know the cost before anyone visits your Wellesley home? Our flashing repair pricing page covers everything from resealing to full replacement and works out an estimate for your chimney. No email, no callback.
Flashing repair in Wellesley is priced by scope and access. A simple re-caulk of sound flashing is the smallest job; full replacement of step, counter, and saddle flashing on a large chimney is the largest. Where a lift is needed rather than a ladder, the access is priced up front. Every option is on our flashing repair pricing page.
Flashing is the metal that seals the joint where the chimney comes through the roof. Brown Chimney uses aluminum or lead-coated copper, and nothing else — no plastic, no rubber. Step flashing goes up the sides course by course, counter flashing tucks into the masonry above it, and chimney-rated elastomeric caulk seals the line. Roof area around the base is restored when the work is done.
Wellesley gives this service a particular character. Pre-war Colonials here are tall and steeply pitched, which makes the roofline harder to reach and the flashing longer than on a modest house. And a storm that arrives sideways off the coast tests the flashing in a way that ordinary rain never does. Method and materials in full on our flashing repair service page.
Water enters at the roofline, travels along a rafter or the back of the masonry, and appears somewhere else entirely — often a floor below and several feet across. Anyone who quotes a chimney leak without going up on the roof is guessing at which of four things is wrong.
The pattern is the diagnostic. A stain that appears in every rain points at the crown or the cap, because vertical water lands on top. A stain that only appears in a nor’easter points at flashing or the weather face, because wind-driven rain arrives sideways and finds vertical seams. Once the source is confirmed, the repair is quoted in writing and crown work or joint repair is priced separately if it is also part of the answer.
Roofline work runs from both Massachusetts offices — Burlington and here — across the wider service area. The full local list is on the Wellesley services page.

Flashing gives itself away indoors long before it looks wrong from the ground. On a steep pre-war roof, most of these are only visible once someone is up there.
The last one is the most useful thing you can tell us on the phone. If the ceiling only stains during a storm and stays dry in ordinary rain, the water is arriving sideways — and that narrows the search to the flashing and the weather face before anyone sets foot on a ladder.

The stain on your ceiling is almost never under the hole. Anyone who quotes a leak repair from the driveway is selling you sealant, not a solution.
The visit starts with finding the source rather than pricing a guess. Roof, crown, cap, joints, and the flashing line are all checked and photographed, and only then is the repair quoted. Most flashing jobs are a single day on site. On the tall Colonials around the Hills, safe access sometimes needs a lift instead of a ladder — that is priced as a separate line and documented with photographs before it appears on a quote.
01
Water stains rarely start where they show. We trace the actual entry point — flashing, crown, cap, or masonry — before quoting anything, because sealing the wrong spot solves nothing.

You approve the exact price before anything is lifted. Chimneys wider than 30 inches at the roofline need a cricket by code — if yours does, that's identified and priced up front.

Failed flashing and hardened sealant come off down to sound roof deck. Any pre-existing shingle damage is documented and quoted separately rather than quietly absorbed.

Step, counter, and saddle flashing set in aluminum or lead-coated copper — never plastic, never rubber — and sealed with chimney-rated elastomeric caulk.

The roof area around the chimney base is restored, the work photographed before and after, and the labor covered by the 1-year workmanship warranty.

Pre-existing roof damage. Worn shingles or a soft deck around the chimney get photographed and documented, but roofing repair beyond the chimney penetration is scoped and priced separately.
Crickets. A chimney wider than 30 inches at the roofline needs a saddle behind it to divert water. That is its own build — framing, membrane, and shingles to match — and its own line on the estimate.
Interior finishes. Where a leak has already marked plaster or ceilings inside the house, we stop the water; the plaster and paint are a separate trade.

Every Brown Chimney job in Wellesley is measured on site, priced in writing, and started only after you approve it. Structural labor carries a 1-year workmanship warranty. Call 781-547-7784 or book online.
