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.

We back every completed job with a 90-Day Done Right Promise in writing. One call brings us back, no arguments, no invoice.
Southborough homeowners have a particular reason to want a local sweep. A lot of these 1980s and 1990s colonials were built with prefabricated fireplace units inside framed chases, and the builder-grade chase covers they came with don’t last. Someone from out of town who doesn’t know the difference between a chase cover and a masonry crown can sell you the wrong fix. Wendell grew up working these streets. He knows the housing stock, the freeze-thaw cycles, and which chimneys on which streets have recurring problems. A national chain can’t say that. Ask anyone on your street.
Our Chimney Cap & Crown Services in Southborough
For homeowners in Southborough, a Chimney Cap & Crown is the first line of defense against water, animals, and the freeze-thaw damage that comes with living at 300-plus feet of elevation in Worcester County. Here’s what we handle, with the local twists that matter.
Cap Installation
Most Southborough homes need either a single-flue cap for a masonry chimney or a specialty chase cover for a prefab fireplace. The two are not interchangeable. A cap for a true masonry stack sits on the flue tile itself. A chase cover caps the entire metal or framed box that houses a prefab unit. Installing the wrong one means water still gets in. We measure on site, account for your flue diameter and termination type, and use stainless or copper so the cap outlasts the roof, not the other way around.
Cap Replacement
If your current cap is rusted at the seams or missing entirely, replacement in Southborough runs $350 to $900 for standard single-flue caps. For the twin-flue chases common on larger executive colonials, you’re looking at $700 to $1,600 for a properly fabricated multi-flue cover. We don’t patch rust with paint. We replace with gauge stainless and proper side screens so rain, snow, and the raccoons that roam the Sudbury River valley stay out.
Crown Repair
Masonry crowns crack because water freezes in the hairline joints and expands. Southborough’s elevation and snow pattern mean this happens faster here than in eastern towns like Natick or Needham. A cracked crown left alone turns into a spalling smoke chamber and eventually a damaged liner. We inspect every crown at each annual cleaning, and if repair is possible, we use proper crown-grade material, not mortar mix. If the damage is too far gone, we rebuild.
Crown Coating
Coating buys time. On a 25-year-old colonial chimney where the crown has started to pit but hasn’t failed structurally, a flexible waterproof coating applied by hand keeps water out and slows the freeze-thaw cycle’s worst effects. For Southborough homes, we’ve had good results with Gelco crown sealant on both masonry crowns and the exposed brick ledges around chase tops. It’s not a forever fix if the crown is already broken, but on the right chimney it can add five to eight years before a full rebuild is needed. Wendell will show you the crown’s condition on camera and tell you plainly whether coating is the right call or a waste of your money.

Trusted Brands We Service in Southborough
We stock and install parts from brands we’ve worked with for years, because we know they hold up in New England weather. That means Gelco for crown coating, Olympia Chimney for caps and chase covers, and Famco for termination components and replacement parts. When we’re in Southborough, we carry the common sizes and profiles on the truck, so most cap and crown jobs finish the same day without ordering and scheduling a return trip. If your existing system uses one of these brands, we can match it. If it’s a builder-grade cover from 1998, we’ll quietly replace it with something that actually works.
Common Chimney Cap & Crown Problems We See in Southborough Homes
- Rusted chase covers on 1990s prefab fireplaces. The original builder covers were often thin galvanized steel that rusts at the seams within 15 to 20 years. Water then drips straight down the flue and into the firebox. On the second-floor master-suite fireplaces in Southborough’s larger colonials, this shows up first as a damp smell near the fireplace before any visible damage appears on the ceiling below.
- Freeze-thaw cracked masonry crowns. At 300 to 400 feet of elevation, Southborough gets more frequent freeze-thaw cycling than towns closer to Boston. Crowns that are perfectly fine last July can show fresh cracking by March. Catch them at the annual cleaning and a $300 to $600 repair is all you need. Wait two winters and you’re budgeting for a rebuild.
- Multi-flue chimneys missing proper caps. Many Southborough homes run a wood-burning fireplace and a gas insert through the same chimney. If only one flue is capped, animals nest in the unused flue, block the draft, and push carbon monoxide back into the house. A proper multi-flue cap sized to both terminations solves it.
- Decorative fireplaces with never-swept flues. The third-floor or master-suite fireplace that got used for a few romantic fires and never touched again often has the glossiest creosote we see all season. Infrequent burning of improperly seasoned wood creates heavy Stage 2 buildup, and homeowners assume a barely-used flue is clean. It isn’t. Cap or no cap, that flue needs sweeping before the next fire.

FAQs - Chimney Cap & Crown in Southborough
Because infrequent fires don’t produce enough heat to burn off the creosote that forms when wood smolders at low temperature. The smoke condenses on a cold flue, especially in a third-floor bedroom chimney that never warms up. Wet or unseasoned wood makes it worse. The flue then holds a glossy Stage 2 creosote layer that catches fire more easily than the dry flaky stuff. Once a year, burn or no burn. Call (781) 390-9211 and we’ll sweep it and show you the brush before and after.
Yes. A prefab fireplace in a framed chase needs a chase cover, which is a flat metal lid sized to the entire chase top, with flue holes and a screen. It’s not the same as the round or square cap that sits directly on a masonry flue tile. If someone puts a masonry-style cap on a chase, water still runs under it and into the chase. We inspect the chase construction and install the right termination the first time.
Southborough sits at higher elevation and averages a colder winter snowpack than Framingham, so the water in your crown’s hairline cracks freezes and thaws more often each season. That means crowns here crack faster, and the damage compounds sooner. A crown that would last 15 years in Framingham might need attention at 10 to 12 years in Southborough. It’s one reason we recommend an annual inspection even in years you never light a fire.
You need a custom multi-flue cap sized to both terminations, with separate screened openings so the gas flue can vent without being blocked by animal nesting or debris. Each flue gets its own screened section, and the cap is built to cover the full chase or crown span. This keeps the unused flue sealed against animals while letting the active one breathe. We measure both terminations and fabricate to fit. Call (781) 390-9211 for a free on-site quote.
Yes, if the spalling is limited to surface pitting and the crown hasn’t cracked through. A flexible waterproof coating like Gelco seals the pores and prevents further water intrusion, which is what drives spalling. We’ll camera the crown and show you the exact extent of the damage before recommending anything. If it’s too far gone, we’ll say so. We don’t coat a crown that’s already done for.
If you’re in Southborough and want a straight answer about your cap, crown, or chase cover, call Wendell at (781) 390-9211. A live person answers, the estimate is free, and the work is backed in writing for 90 days.
