Chimney Repair in Brentwood
Chimney sweep, inspection, and masonry repair in Brentwood — a Gateway Arts District community of 1920s-40s Craftsman bungalows and Colonial Revivals. Original brick chimneys are now a century into Maryland freeze-thaw and need crown rebuilds, matched-brick repair, and full stainless relining.

Chimney Service in Brentwood, MD
Brentwood is a small Prince George's County town inside the celebrated Gateway Arts District, just over the DC line near the 38th Street corridor. The town has retained its early-20th-century streetscape of 1920s-40s Craftsman bungalows, Foursquares, and Colonial Revivals, and you can walk past former trolley-suburb porches that have been the same for a hundred years. Residents value the artist-studio character, the proximity to the Anacostia River trail, and the short commute to Brookland and downtown DC, but the housing stock comes with a century of accumulated chimney problems we see every week.
Most Brentwood chimneys are original to the home — single-flue brick stacks built with soft red brick and lime-based mortar set on undersized footings. After a century of Maryland freeze-thaw, those chimneys typically need matched-brick replacement above the roofline, full lime-mortar repointing, a poured concrete crown to replace the original mortar wash, and 316Ti stainless relining sized for whatever modern appliance now lives downstairs (most often a gas insert that replaced the original wood-burning firebox).
Common Chimney Issues in Brentwood
Here are the chimney problems we see most often from Brentwood homeowners.
Spalled Soft Brick Above the Roofline
Century-old Brentwood chimneys were built with soft red brick that absorbs water readily. After a hundred Maryland winters of freeze-thaw, brick faces have spalled off, leaving pitted, weakened masonry exposed to more water. We replace damaged courses with reclaimed or color-matched soft brick, set in lime-based Type N mortar to match the original wall, then waterproof with ChimneySaver vapor-permeable sealer.
Lime-Mortar Joint Erosion
Original 1920s lime mortar washes out faster than modern Portland-based mortar, and most Brentwood chimneys have joints eroded 3/4 inch or more behind the brick face. We grind out failed joints and repoint with historically appropriate Type N lime-Portland mortar — not the hard Type S that would crack the soft surrounding brick.
Undersized Original Flues for Modern Gas Inserts
Brentwood homeowners converting from open wood fireplaces to gas inserts almost always have a flue that is dramatically oversized for the new appliance. We size and install a 316Ti stainless steel liner — properly insulated with Thermix wrap — matched to the new appliance's Btu input and vent length so combustion gases stay above dewpoint and the masonry stays dry.
Missing or Improper Chimney Caps
Original 1920s-40s Brentwood chimneys were built without caps. A century of squirrels, starlings, and rain has done serious damage to flues. We install custom-sized stainless caps — most original Brentwood flues are odd dimensions that require custom-fit work, not off-the-shelf hardware-store caps.
Brentwood Housing & Chimneys
Brentwood is dominated by 1920s-40s working-class Craftsman bungalows and Colonial Revivals built during the streetcar-suburb expansion along the 38th Street corridor and Rhode Island Avenue. The North Brentwood section (the first incorporated Black municipality in Prince George's County) features a similar pre-war housing stock with detached bungalows on small lots. Original brick chimneys serve a single open masonry fireplace per home, and almost all are now a century old with century-old lime mortar, soft brick, and no liner of any kind. Pockets of 1950s-60s infill ranchers appear near the Hyattsville border with masonry chimneys built to mid-century standards. Across all eras, our job is balancing historic preservation with modern code compliance — period-appropriate repair on the outside, stainless steel relining on the inside.
How Maryland Weather Affects Chimneys in Brentwood
Brentwood sits inside the DC-Beltway urban heat island, which means the masonry sees stronger summer thermal cycling than the western Maryland suburbs, but it still gets the full Maryland freeze-thaw winter (40-plus freeze events, USDA zone 7a). The Anacostia floodplain on the east side raises ambient humidity year-round, which keeps chimney brick damp longer after each rain — accelerating spalling and efflorescence on south and west exposures. Summer thunderstorm gusts off the river drive wind-driven rain past failed flashing, and winter ice damming on low-pitch porch roofs leaks into chimneys at the chase intersection. We see all of those failure modes on Brentwood Level 2 inspections every season.

Brentwood Chimney Repair — FAQs
Common questions from Brentwood, MD homeowners.
Do you do historically appropriate repair on pre-war Brentwood chimneys?
Yes. We use lime-based Type N mortar (not hard Portland Type S) for repointing, source reclaimed or color-matched soft brick for replacement courses, and select custom-fit stainless caps for non-standard original flue openings. Documentation we leave references NFPA 211 and historic masonry preservation standards.
How much does a chimney rebuild cost in Brentwood?
The price depends on how much of the chimney has to be rebuilt, its height and roof access, how many flues need relining, and the condition of the brick and mortar. The estimate is free, and no work begins without your approval.
Can you reline an original 1920s flue for a modern gas insert?
Yes. We size a 316Ti or 304 stainless liner — properly insulated — to match the appliance Btu input and vent height per NFPA 211 and the appliance manufacturer's instructions. Original Brentwood flues are almost always oversized for modern high-efficiency gas, and an unlined oversized flue will condense moisture inside the brick and destroy it.
Do you serve all of Brentwood and North Brentwood?
Yes. We serve all addresses in ZIP code 20722, including North Brentwood, the 38th Street corridor, the Hyattsville border, and the Gateway Arts District.
Do you offer 24/7 emergency service in Brentwood?
Yes. Eagle Chimney Service responds 24/7 to chimney fires, active leaks, carbon monoxide alarms, and animals trapped in the flue. Call (855) 424-6217 anytime.
