We’ve been walking roofs in Bethlehem for over 42 years, from the historic stone homes on Main Street to the mid-century colonials in West Bethlehem and the hillside properties along Saucon Valley Road. Russell Haines built this company on a straightforward idea: show the homeowner exactly what you found, explain what it means in plain English, and fix it so you don’t have to think about it again. That’s the Keystone Standard, and it’s still how we operate today.

Our technicians carry background checks, wear uniforms, and arrive with the tools and materials to finish most repairs in one trip. Every inspection includes a Level-2 camera examination with photos you can see for yourself and a written verdict you can understand. No jargon, no hidden damage invented to pad a bill, no surprises when the invoice arrives. If we don’t do it right, we come back and make it right, backed by our 90-Day Done Right Promise in writing with no arguing.

Bethlehem’s freeze-thaw cycles hit chimneys harder than many homeowners realize. Water seeps into hairline cracks in October, freezes and expands through January, and by March you’ve got spalling brick, deteriorated mortar, or a leaning chimney stack. The homes near the Monocacy Creek floodplain and the older masonry in Historic Bethlehem are particularly susceptible. We’ve repaired chimneys on every type of construction in this city, and we know which problems develop where and why.

What Our Chimney Repair Service Includes

Mortar Repointing

Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, properly matched mortar into the joints. In Bethlehem, we see this need most often in homes built before 1960 with original lime-based mortar that has simply weathered away after decades of Lehigh Valley winters. Our technicians use mortar mixes matched to the original composition and compressive strength, not generic Type N from a big-box store, so the repair moves and breathes with the original masonry. We document the depth of erosion with camera photos before we start, and we show you the finished joints before we leave.

Spalling Brick Repair

Spalling occurs when water trapped inside brick freezes and forces the face of the brick to flake off or crumble entirely. Bethlehem’s 25-30 annual freeze-thaw cycles, combined with the porous nature of older brick, make this one of the most common repairs we perform, especially on south- and west-facing chimneys that absorb maximum sun and rain. We remove damaged bricks and replace them with matching units salvaged from regional suppliers or, when necessary, custom-ordered to match historic blends. In Fountain Hill and the historic district, we’ve developed relationships with specialty brickyards that stock the exact profiles and colors used in Bethlehem’s 19th and early 20th century construction.

Chimney Waterproofing

Waterproofing is the application of a vapor-permeable sealant that blocks liquid water from entering masonry while allowing trapped moisture to escape. We apply professional-grade treatments from Copperfield and Famco after all necessary repairs are complete, never over damaged brick or failing mortar where sealing would trap moisture and accelerate deterioration. A typical Bethlehem chimney requires two coats with attention to the crown, the shoulder where the chimney meets the roofline, and the base flashing. We warranty our waterproofing applications for five years because we’ve seen too many homeowners pay for a “waterproofing” that was simply Thompson’s Water Seal slapped on by a handyman who didn’t understand vapor permeability.

Flashing Repair

Flashing is the sheet metal system that bridges the gap between your chimney and roof, and it’s the single most common source of chimney-related leaks we find in Bethlehem inspections. The combination of steep slate and tile roofs on older homes with the thermal movement of masonry stacks creates stress points that separate, corrode, or pull free. We fabricate and install custom flashing using copper or heavy-gauge galvanized steel, sealed with high-temperature sealants and mechanical fasteners, not caulk alone. In neighborhoods like Hokendauqua and Catasauqua where wind exposure is higher, we pay particular attention to the counter-flashing reglets cut into mortar joints, which are often the first point of failure.

Chimney Rebuilding

Partial or complete chimney rebuilding becomes necessary when structural integrity is compromised by widespread mortar failure, extensive spalling, foundation settling, or catastrophic water damage. We’ve rebuilt chimneys from the roofline up in Bethlehem’s South Side after years of deferred maintenance, and we’ve reconstructed full exterior stacks on homes in East Allen where lightning or vehicle impact caused sudden collapse. Our rebuilds use matching brick and mortar, proper internal flue lining with DuraFlex or HeatShield systems, and reinforced concrete crowns pitched to shed water. Every rebuild includes a written structural assessment, progress photos, and final inspection with the homeowner present if they wish.

Tuckpointing

Tuckpointing is a specialized form of repointing that recreates the fine, narrow mortar joints characteristic of historic masonry, often with a contrasting “tuck” line pressed into the center for visual precision. Bethlehem’s Moravian-era buildings and Victorian-era homes in the historic district require this level of craftsmanship to maintain architectural integrity and, in some cases, to satisfy historic preservation guidelines. Our technicians are trained in traditional tuckpointing techniques using hawk and trowel, not modern pumping methods that produce sloppy, oversized joints. We’ve worked on properties where the Historic Bethlehem Partnership or local preservation boards required specific mortar analysis and approval, and we document our materials and methods to satisfy those requirements.

Brands We Service for Chimney Repair

We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind our work. For chimney liners and relining systems, we specify DuraFlex stainless steel liners for their corrugated construction that accommodates offset flues common in Bethlehem’s older homes, and HeatShield cerfractory resurfacing for restoring deteriorated clay flue tiles without full replacement. We’ve installed hundreds of DuraFlex systems in Lehigh Valley chimneys and stock the full range of diameters and connection components so we’re not ordering parts and making you wait.

For chimney caps, dampers, and exterior protection, we source from Famco and Copperfield, brands whose galvanized and stainless steel components withstand Bethlehem’s freeze-thaw cycling without the rust-through we see on discount hardware-store caps after three or four seasons. Whether your existing system is DuraFlex, HeatShield, Famco, Copperfield, or any other make, we can service it, repair it, or replace it with components that fit and function as intended. We don’t substitute builder-grade materials to pad margin, and we’ll show you the brand markings on every component we install.

Signs You Need Chimney Repair Right Now

• White staining (efflorescence) on exterior brick indicates soluble salts being drawn to the surface by moisture moving through the masonry. It’s not just cosmetic; it signals water saturation inside the wall that will eventually destroy mortar joints and spall brick faces. In Bethlehem’s clay-heavy soils, we’ve seen efflorescence precede major structural damage by as little as two winters.
• Cracked or missing mortar joints create pathways for water infiltration and reduce the structural bond that keeps your chimney stack intact. A joint you can slide a quarter into is a joint that needs repointing now, not next season. We’ve responded to calls from West Bethlehem homeowners who watched a small mortar gap become a leaning chimney over a single winter of freeze-thaw.
• Loose or crumbling bricks mean the freeze-thaw cycle has already advanced beyond surface spalling into structural compromise. A brick that moves when you press it is a brick that can fall, potentially through your roof or onto a walkway below. This condition demands immediate inspection and likely partial rebuilding.
• Rust stains on the chimney exterior or in the firebox indicate moisture is reaching metal components, typically the damper, fire grate, or liner connection. Rust accelerates rapidly once established, and in Bethlehem’s humid summers, a damp chimney interior can corrode a steel damper beyond repair in a single season. The underlying moisture problem must be found and fixed, not just the rust cleaned.
• Damp or stained ceiling drywall adjacent to the chimney chase is evidence that flashing, crown, or masonry failure is allowing water into your home’s envelope. By the time staining appears on drywall, the actual leak has typically been active for weeks or months, and insulation, framing, or ceiling joists may already be compromised. Camera inspection can trace the exact entry point without tearing into finished surfaces.

Our Chimney Repair Process - Step by Step

1. 1
   Schedule your inspection. Call (610) 595-5754 and a live person will answer, 24 hours a day, every day. We’ll find a time that works for your schedule, typically within a few business days during peak season and often sooner in off-peak months. We’ll confirm your address, note any specific concerns you’ve observed, and explain what to expect.
2. 2
   Level-2 camera inspection and documentation. Our technician arrives in uniform, introduces themselves, and begins with a visual assessment of the exterior from roof level and the interior from the firebox up. We feed a high-resolution camera up the flue to document liner condition, creosote buildup, and any obstructions or structural defects. Every significant finding is photographed and saved to your job record.
3. 3
   Plain-English verdict and upfront pricing. We sit down with you, show the photos on a tablet, and explain what we’re seeing in language you can understand. If repair is needed, we provide a written estimate with line-item pricing, not a single vague number. The price we quote is the price on the invoice. No surprises, no “we found something else” add-ons after you’ve approved the work.
4. 4
   Professional repair with matched materials. For most standard repairs, our technician completes the work during the same visit, using materials matched to your chimney’s construction and components from the professional-grade brands we trust. We protect your property with drop cloths, we clean up thoroughly, and we run a final camera pass to verify the repair before we leave.
5. 5
   Written documentation and 90-Day Done Right Promise. You receive a complete report with before-and-after photos, a description of work performed, materials used, and our 90-Day Done Right Promise in writing. If anything isn’t right, call us and we make it right with no paperwork and no arguing. We’ve honored this promise hundreds of times in 42 years, and our reputation in Bethlehem depends on continuing to do so.
