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.

Silver Spring Chimney Repair typically costs between $350 and $4,500 depending on the scope, with most common repairs like mortar repointing or flashing work falling in the $500-$1,800 range. Most jobs are completed in a single visit, and Hearthstone Chimney Co. has been doing this work in Montgomery County for over 42 years. Call (301) 479-9806 to speak with a live person any hour of the day.
We’ve worked on chimneys in every corner of Silver Spring, from the older brick colonials near downtown to the mid-century homes around Four Corners and the hillside properties off New Hampshire Avenue where winter wind drives rain straight into deteriorating mortar joints. Russell Haines started this company in 1984, and we’ve learned that Silver Spring’s freeze-thaw cycles - hard freezes followed by mild, wet days - punish chimney masonry harder than almost any climate pattern in Maryland. The brick absorbs moisture, the temperature drops overnight, the water expands, and by spring you’re looking at spalling faces and crumbling joints.
Our customers here tend to be longtime homeowners. They’ve lived in the same house for twenty or thirty years. They’ve already been burned by a contractor who talked fast, disappeared faster, and left a mess. They don’t want flash. They want someone who shows up when they say, explains what they found, fixes only what needs fixing, and stands behind the work. That’s the only way we’ve stayed in business since 1984.
Every repair starts with a Level-2 camera inspection. You get photos you can see, a plain-English verdict, and a written estimate with no-hassle upfront pricing. The number on the estimate is the number on the invoice. And everything we do is backed by the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar Repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Silver Spring, we see this need most often on chimneys built before 1980 where the original lime-based mortar has simply weathered away after decades of Montgomery County freeze-thaw cycles. We use professional-grade mortar mixes formulated to match the original in compressive strength and permeability, never the cheap bagged mortar you’ll find at hardware stores that traps moisture and accelerates deterioration.
Spalling Brick Repair
Spalling Brick Repair addresses what happens when water freezes inside brick faces, causing the surface to flake, pop, or crumble away. It’s common on Silver Spring chimneys that lack proper crown overhang or where previous repairs used non-breathable sealers. We remove spalled bricks to sound substrate, source matching replacements when possible, and address the underlying moisture intrusion so the problem stops repeating. In neighborhoods like Woodmoor and Northwood, where many chimneys date to the 1950s and 1960s, we’ve replaced thousands of spalled bricks and know which local suppliers still carry compatible face brick.
Chimney Waterproofing
Chimney waterproofing isn’t a coat of generic sealer from a big-box store. It’s a breathable, silane-based treatment that repels liquid water while allowing vapor to escape. We apply professional-grade waterproofing products from brands like HeatShield and Copperfield, formulated specifically for masonry chimneys rather than generic concrete sealers that do more harm than good. Silver Spring’s combination of summer humidity and winter freeze-thaw makes this service particularly valuable for extending the life of sound but porous masonry.
Flashing Repair
Flashing is the sheet metal that seals the joint where your chimney passes through the roof. When it corrodes, pulls loose, or was never installed correctly, water runs straight into your attic and down your walls. We repair and replace flashing using proper step-flashing and counterflashing techniques, sealed with high-temperature sealants. In Silver Spring’s older neighborhoods, we frequently find original flashing that’s simply reached end of life, or worse, DIY repairs with roofing cement that cracked within a season.
Chimney Rebuilding
Sometimes the damage is too extensive for spot repairs. A partial or full chimney rebuild removes deteriorated masonry and reconstructs to current code, with proper crown design, flue lining, and clearance to combustibles. We’ve rebuilt chimneys in Silver Spring after lightning strikes, long-neglected maintenance, and in one case on a Sligo Park Hills home where a tree limb took out the upper courses. Every rebuild includes engineered drawings when required, permit coordination with Montgomery County, and materials from trusted brands like Olympia Chimney and DuraFlex.
Tuckpointing
Tuckpointing is the decorative and functional technique of removing old mortar and replacing it with new mortar colored to match, sometimes with a thin contrasting line for traditional appearance. On Silver Spring’s historic homes, particularly in the Chimney Repair in Silver Spring corridor near downtown, proper tuckpointing preserves architectural character while restoring weather resistance. We color-match on site and tool the joints to match existing profiles, whether that’s concave, V-joint, or weatherstruck.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from industry-trusted manufacturers. For chimney liners and relining components, we specify DuraFlex and Olympia Chimney products - DuraFlex for their corrugated stainless steel liners that handle the thermal expansion stresses we see in Silver Spring’s heating-season extremes, and Olympia Chimney for their precision-engineered connector systems and support components. We’ve installed hundreds of both and keep common sizes in stock.
For refractory repair and resurfacing, we use HeatShield’s cerfractory technology, which bonds to existing flue tile at the molecular level and has performed well in our local installations for over a decade. For waterproofing, crown repair, and flashing components, we source from Gelco and Famco. Whether you have one of these brands already installed or need us to recommend the right product for your specific chimney condition, we can help. We don’t use builder-grade substitutes, and we don’t guess.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on exterior brick - This powdery deposit means water is moving through your masonry, dissolving salts, and depositing them on the surface. It’s not just cosmetic. In Silver Spring’s climate, that water is freezing and expanding inside your brick every winter, accelerating spalling and mortar decay. We’ve seen efflorescence on chimneys in Wheaton and Takoma Park that looked minor from the ground but concealed significant internal deterioration.
- Missing or deteriorated mortar joints - Gaps between bricks let water pour straight into the wall structure. On chimneys visible from Silver Spring’s many tree-lined streets, this is often visible from the ground with binoculars. We repointed a chimney last year on a home near Forest Glen where the owner had watched mortar fall out for three seasons before calling. The delay turned a $900 repointing job into a $3,200 rebuild of the upper courses.
- Crumbling or cracked chimney crown - The concrete crown at your chimney’s top is its first defense against water. When it cracks, water saturates the masonry below. Silver Spring’s summer thunderstorms drive water hard into crown cracks, and winter freeze-thaw opens them wider. We repair crowns with specialized crown coat materials or pour new reinforced crowns when the original is beyond saving.
- Rust stains on exterior or in firebox - Rust means moisture is reaching metal components, whether that’s a deteriorated flue liner, failing damper, or compromised flashing. In homes near Silver Spring’s more humid bottomlands, like areas close to Rock Creek or Sligo Creek, we’ve traced rust stains to capillary moisture wicking up from saturated foundations. The repair isn’t just cosmetic - it’s stopping ongoing corrosion that compromises structural and venting safety.
- Damp or stained ceiling near chimney - This almost always means flashing failure or crown leakage, and it’s the sign most likely to drive real interior damage. We’ve responded to calls from Silver Spring homeowners who waited until drywall collapsed. The repair is straightforward when caught early. When delayed, you’re looking at chimney repair plus interior remediation.
Our Chimney Repair Process - Step by Step
- 1
Schedule your inspection. Call (301) 479-9806 and a live person answers, 24 hours a day. We’ll find a time that works, typically within a few days for non-urgent repairs. We don’t do phone estimates - every chimney is different, and guessing from a description does you no favors.
- 2
Level-2 camera inspection and documentation. Our technician arrives in uniform, background-checked, with a photo ID. We set up our camera system and inspect the flue interior, crown, cap, flashing, and exterior masonry. You get photos you can see and a plain-English verdict, documented like an engineer and explained like a craftsman.
- 3
Written estimate with upfront pricing. We explain what needs repair, what can wait, and what’s preventive. The estimate is itemized and fixed - the number you see is the number on the invoice. No surprises, no upsells after work begins. We also note anything that doesn’t need attention, because our interest is in your chimney’s health, not this month’s revenue.
- 4
Repair completion, typically in one visit. Most Silver Spring chimney repairs are completed in a single day by our uniformed, background-checked technicians. We use professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no substitutes. The work area is protected and cleaned before we leave.

How Much Does Chimney Repair Cost in Silver Spring?
How much Chimney Repair costs in Silver Spring varies with the scope of work, access difficulty, and materials required. Here’s what typical repairs run in our current market:
| Repair Type | Typical Range in Silver Spring | What Affects Price |
|---|---|---|
| Mortar repointing (partial) | $500 - $1,400 | Height, accessibility, mortar color matching needs |
| Spalling brick repair (localized) | $650 - $1,800 | Number of bricks, matching availability, underlying moisture cause |
| Chimney waterproofing | $350 - $950 | Surface area, prep cleaning required, accessibility |
| Flashing repair/replacement | $450 - $1,200 | Roof pitch, chimney size, extent of water damage to surrounding structure |
| Crown repair or rebuild | $600 - $2,100 | Size, reinforcement needs, access |
| Partial chimney rebuild | $2,500 - $6,500 | Height of rebuild, scaffolding needs, liner work required |
| Full chimney rebuild | $4,500 - $12,000+ | Height, design complexity, permit requirements, liner system |
Several factors push costs higher or lower. Chimney height matters - two-story Silver Spring homes with steep roofs require more labor and often scaffolding. Access matters - chimneys tight against rooflines or surrounded by mature trees take more time. And the underlying condition matters - repairing masonry without addressing the water source that damaged it is wasted money, which is why our inspections always trace causes, not just symptoms.
The best way to avoid overpaying is to get a documented inspection with photos you can see, not a verbal “that’ll be about…” from someone who never climbed your roof. We offer free estimates, and our Free Second Opinion on any written estimate means you can compare apples to apples. We’ve reviewed competitor estimates in Silver Spring that proposed full rebuilds for problems that repointing would solve, and we’ve caught underspecified jobs that would have failed within seasons.
Our estimates include all materials, labor, cleanup, and the 90-Day Done Right Promise. No hidden charges, no “we found something else” add-ons after you sign. Call (301) 479-9806 for your exact quote - estimates are free.
