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.

AfterChimney Cleaning in Bethesda, MD
Chimney cap and crown work in Bethesda is driven by two realities: 1930s-1950s masonry chimneys with original corbeled crowns, and a freeze-thaw cycle that opens cracks in them every winter. Most Bethesda homeowners call us because water is getting in, or because a pre-sale inspection flagged the crown before closing. Call (240) 220-9395 for a written price and a documented photo record on every job.
Why Bethesda Homes Are Different
Bethesda’s established neighborhoods like Kenwood and Edgemoor are filled with Colonial and Tudor Revival homes built between 1935 and 1965. These houses carry original multi-flue masonry chimneys with clay tile liners and corbeled crowns that have often gone decades without meaningful service. That matters because Bethesda sits squarely in the mid-Atlantic freeze-thaw belt, cycling through 30 to 50 freeze events each winter with over 40 inches of annual precipitation. Water enters small crown and mortar cracks, freezes, expands, and spalls the masonry from the inside out. Humid summers add moss growth on north-facing chimney faces, trapping moisture against already-stressed brick. We regularly find crown fractures and deteriorated liner sections in homes that look immaculate from the street. A camera scan down the flue is the only way to see what’s actually happening behind the brick.
Our Main Bethesda Services
The two services Bethesda homeowners call about most are chimney cleaning and repair, with fireplace work close behind. Here’s what each involves in this market.
Chimney Cleaning & Sweep in Bethesda
Most Bethesda chimneys we clean haven’t been swept in years, and many show Class II or III creosote buildup from years of wood burning. A Level 2 camera inspection during the sweep catches what a basic brush job misses: cracked tile sections, failed dampers, or gas-conversion flues that don’t meet Montgomery County code. We document everything with photos you keep. Chimney Cleaning & Sweep in Bethesda covers the full scope, pricing, and what the camera record includes.
Chimney Repair in Bethesda
Freeze-thaw damage shows up here as spalling brick, open mortar joints, and cracked crowns. In Bethesda’s older Colonials, we also see failed dampers and smoke chamber damage that homeowners don’t notice until a fire doesn’t draw or a pre-sale inspection flags it. Chimney Repair in Bethesda details repair options, cost drivers, and how we document the existing condition before any work is quoted.
Fireplace Services in Bethesda
Many 1940s and 1950s Bethesda fireplaces were converted to gas in the 1980s and 1990s but kept their original unlined clay tile flues. That’s a code deficiency that surfaces during sale inspections on million-dollar homes. Fireplace Services in Bethesda walks through gas log conversion checks, fireplace rebuilds, and the inspection standards we follow.

BeforeAfterChimney Cap & Crown in Bethesda
In Bethesda, chimney crowns on 1940s and 1950s Colonials and Tudors are original corbeled mortar work that was never designed for 40 inches of annual rain and repeated freeze cycles. The caps are often missing entirely, or rusted through, leaving the flue open to rain, birds, and debris. We see this pattern constantly in Kenwood and Edgemoor, where deferred crown maintenance turns into interior water damage and negotiating leverage on pre-sale inspections. Chimney Cap & Crown work here starts with a camera scan to document what’s actually failing before we quote anything.
Cap Installation
Signs you need it
Rain dripping into the firebox, birds nesting in the flue, or a missing cap visible from the ground.
What it costs in Bethesda
A new stainless steel cap in Bethesda typically runs $380-$650 installed, depending on flue size and access.
How we do it
We measure the flue opening, install a stainless cap with proper fastening, and photograph the finished work.
Crown Repair
Signs you need it
Hairline cracks across the crown surface, spalled mortar chunks on the roof, or efflorescence staining the brick below the crown.
What it costs in Bethesda
Crown repair in Bethesda generally runs $450-$1,200 depending on crack extent and whether full resurfacing is needed.
How we do it
We clean the crown surface, fill and seal cracks with a flexible crown coat, and document before and after with photos.
What Chimney Cap & Crown Costs in Bethesda
| Item | Typical range in Bethesda |
|---|---|
| Cap installation | $380-$650 |
| Crown repair | $450-$1,200 |
| Crown coating | $600-$1,500 |
How long does a chimney crown repair last in Bethesda?
A properly sealed and coated crown typically lasts 10 to 15 years in Bethesda’s freeze-thaw climate. Regular inspection during your annual cleaning catches early cracking before water gets behind the mortar. Call (240) 220-9395 for a written assessment.
Does a missing chimney cap cause structural damage?
Yes. Open flues let rain, snow, and animals in. Water mixing with creosote creates acidic compounds that attack the liner and mortar joints. We see accelerating deterioration in uncapped Bethesda chimneys every winter.
Chimney Liner & Rebuild in Bethesda
Bethesda’s original clay tile liners from the 1930s through 1960s are now 60 to 90 years old, and freeze-thaw cycling has cracked a large share of them. In homes converted to gas decades ago, those same original unlined flues fail current Montgomery County venting code. A camera scan makes the liner condition undeniable before any rebuild is quoted. Chimney Liner & Rebuild work in Bethesda often starts with a pre-sale inspection finding, not a visible problem.
Stainless Steel Liner
Signs you need it
Cracked clay tile sections visible on the camera scan, or a gas appliance venting through an unlined flue.
What it costs in Bethesda
A stainless steel liner for a typical Bethesda chimney runs $2,800-$5,500 installed.
How we do it
We size the liner to the appliance, install it through the existing flue, and verify the installation with a post-install camera scan.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, a leaning chimney section, or extensive mortar joint failure visible from the ground.
What it costs in Bethesda
A partial rebuild in Bethesda typically runs $2,500-$6,000 depending on how many courses of brick need replacement.
How we do it
We remove deteriorated brick to solid masonry, rebuild with matched brick and new mortar, and photograph each stage.
What Chimney Liner & Rebuild Costs in Bethesda
| Item | Typical range in Bethesda |
|---|---|
| Stainless steel liner | $2,800-$5,500 |
| Partial rebuild | $2,500-$6,000 |
| Full chimney rebuild | $9,000-$20,000+ |
Do I really need a new liner, or can it wait?
If the camera shows cracked tile sections, do not wait. Cracked liners allow heat and gases to reach combustible framing. In a gas-converted Bethesda fireplace on an unlined flue, it’s already a code violation. Call (240) 220-9395 for the camera evidence.
How does a partial rebuild compare to a full rebuild in cost?
A partial rebuild replaces only the deteriorated section above the roofline, typically $2,500-$6,000 in Bethesda. A full rebuild from the firebox up starts around $9,000. The camera and masonry assessment determine which applies.
