Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Chimney Flashing Repair in Belmont
Chimney Flashing Repair is one of the most common calls we take across Belmont, and for good reason. The flashing is the metal seal where the chimney meets the roofline, and on Belmont’s older ranch homes it was often installed with mastic rather than proper step and counter-flashing. After decades of winter rain and sun, mastic dries out, cracks, and pulls away from the brick. Water gets behind it, travels down the chimney chase, and shows up as a ceiling stain two floors below where the actual leak lives.
A proper flashing repair in Belmont typically runs $350 – $800 depending on how much of the existing flashing can be salvaged. If the roofline is steep or the chimney sits on a hillside lot with difficult access, it lands toward the higher end. On a standard single-story ranch, it’s usually under $600.
How We Fix It
We remove the old flashing and install step flashing at the roofline with counter-flashing cut into the mortar joints. This is the correct method for Belmont’s wet winters, and it’s the same approach we use on our larger Chimney Repair projects. We then seal every seam with a polyurethane sealant rated for exterior masonry, not a cheap tube of caulk.
What a Photo Report Shows You
Before we touch anything, we run a camera up the flue and along the roofline. You’ll see photos of the failed flashing, the water entry point, and exactly what we’re replacing. If the flashing is intact and the leak is coming from somewhere else, we’ll tell you that too, flat out.
Chimney Crown Repair in Belmont
Chimney Crown Repair is the fix for the concrete slab that caps the top of your chimney, and Belmont’s mid-century homes often need it sooner than their owners expect. The original crowns on these chimneys were poured thin, sometimes without proper overhang, and after 50 – 60 years of winter rain cycles, they crack. Those cracks let water into the smoke chamber, where it rusts the damper and erodes mortar joints from the inside.
Crown repair in Belmont generally runs $400 – $900. A simple crack fill with a proper crown sealant lands on the low end. A full crown replacement, where we chip off the old concrete and pour a new one with the correct 2-inch overhang and drip edge, runs higher. If you’re hearing loose concrete chips fall into the firebox, you’re likely looking at a full replacement.
What a Proper Crown Should Look Like
A new crown needs to slope away from the flue, extend past the chimney’s edge, and include a drip edge that keeps water from running down the brick face. Many Belmont chimneys never had any of that. We pour using a Portland-based mortar mix blended for exterior masonry, then seal it. This is not a cosmetic fix, it is the thing that keeps your chimney standing.
Crown vs. Cap: Don’t Confuse Them
The crown is the concrete. The cap is the metal cover over the flue opening. They work together, and when one fails, the other usually follows. We inspect both on every visit and include photos of each in the report you receive.
Trusted Brands We Service in Belmont
We stock and work with professional-grade materials because a repair is only as good as what goes into it. For flue relining, we specify DuraFlex stainless liners sized to the appliance connected, not the fireplace that was originally built. For crown and masonry work, we use commercial sealants and mortars, not big-box products. We also work regularly with Famco caps and dampers and Copperfield flashing components. These are brands trade professionals know, and you’re welcome to look them up before we ever arrive. If you need a second opinion or want to verify a product spec, we’ll give you the exact part number in writing.
Common Chimney Repair Problems We See in Belmont Homes
- Oversized flue liners on homes with wood inserts. Belmont’s mid-century ranch homes were built with masonry fireplaces designed for open burning. When a wood insert or stove is added, the original flue is too large for the appliance, so draft suffers and creosote accumulates faster than you’d expect.
- Cracked clay tile joints from seismic movement. The hillside lots throughout Belmont mean original clay tile flues were often laid to blueprints that predate modern seismic standards. We regularly find cracked tile joints behind what looks like a clean smoke chamber.
- Failed crowns and spalled brick from winter rain. Decades of rain and nearby tree cover cause spalling and cracked crowns that let water into the smoke chamber and rust the damper. Original crowns on these chimneys were rarely poured with proper overhang.
- Mastic-based flashing failure. Flashing on these homes was typically installed with old mastic rather than step and counter-flashing. Leaks around the chimney chase are common even when the flue itself looks fine from the ground.

FAQs About Chimney Repair in Belmont
No, not necessarily. If you burn less than a cord a year and have a straight clay flue on a traditional fireplace, a Level 1 inspection every two years is usually fine. What changes that, fast, is a wood insert or stove on an undersized or oversized flue, which describes a lot of Belmont ranch homes. Then creosote builds faster, draft problems appear, and an annual check is cheap insurance. Call (830) 251-4560 and we’ll tell you plainly what your specific setup needs.
A Level 1 inspection is a visual check of the accessible parts of the chimney, no camera. A Level 2 adds a camera scan down the flue and is required when you buy or sell a home, after a chimney fire, or when you change the appliance. A Level 3 involves opening up part of the chimney structure, usually after a serious fire or structural failure. Most Belmont homeowners with a standard fireplace need a Chimney Inspection in Belmont at Level 1. If you have an insert or stove, you need a Level 2 at least once. Call (830) 251-4560 and we’ll tell you which applies to you, and why.
For an open fireplace burning dry hardwoods, once a year before the burning season. For a wood stove or insert, more often, usually twice a season if you burn regularly. The rule is simple: when creosote builds to 1/8 inch, it gets swept. If you don’t know what yours looks like, that’s the point of an inspection.
Third-degree creosote is the hard, glazed, tar-like form that forms when flue temperatures are too low, often because the liner is oversized. You cannot brush it off. It requires chemical treatment or rotary cleaning with chains, and in serious cases, liner replacement. This is exactly what we found on a 1962 ranch in the Haskins Estates area: an oversized clay flue on a wood insert had glazed the top several feet. We pulled the old liner, set a DuraFlex stainless liner sized to the insert, rebuilt the crown, and reappointed the firebox. The draft measured properly afterward, and the chimney finally matched the appliance it was serving.
Cracked crowns and loose flashing can wait, but not forever. Every winter rain cycle pushes more water into the masonry, and spalling accelerates quickly once moisture gets trapped in the brick. If you can see a ceiling stain developing, do not wait. If the damage is cosmetic and the leak is not yet active inside, a season’s delay is not reckless, but you should photograph it monthly. Call (830) 251-4560 and we’ll tell you honestly whether yours needs attention now or can safely wait.
