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’ve been working the stone farmhouses and colonial-era chimneys along River Road and throughout Williams for decades. Our crews know the difference between a standard cap job and the kind of multi-opening stack restoration these old Delaware River valley homes actually need. Dispatch is coordinated from our Philadelphia office, but our trucks are in Northampton County regularly, and we don’t make Williams homeowners wait a week for a tech who understands 18th-century masonry.
Why Hearthstone Chimney Co. Is Williams’s Preferred Chimney Cap & Crown Company
Our reputation in Williams was built on River Road farmsteads where homeowners had already been told they needed full rebuilds by sweeps who never ran a camera. We document every flue with Level 2 inspection photography, show you the footage, and give you a plain-English verdict. No surprises on the bill. The number on the estimate is the number on the invoice.
We’ve served local communities for over 42 years, and we plan to be here in thirty more. That changes how we treat people. Our 90-Day Done Right Promise is in writing, no arguing - if it’s not right, we come back. Calls are answered by a live person 24 hours a day, 7 days a week. Our technicians are background-checked, uniformed, and carry professional-grade materials from Famco, Copperfield, and DuraFlex on every truck.
Williams Township’s river-valley humidity and freeze-thaw cycles are hard on masonry. A tech who treats your chimney like a suburban tract-home flue will miss the spalling mortar and efflorescence that Delaware River fog drives into these old stacks. We don’t miss it. We know what to look for because we’ve seen it hundreds of times.
Our Chimney Cap & Crown Services in Williams
Cap Installation
New cap installation in Williams starts around $280-$450 for a standard single-flue galvanized or stainless unit. On the older farmhouses near the Delaware, we often find the flue tile is oversized for modern appliances, or the chimney was built without a flue liner at all. A cap alone won’t fix a drafting problem caused by flue sizing. We run the camera first. If the cap is all you need, we install it. If the flue is wrong, we show you the footage and explain why.
Cap Replacement
Caps rust, blow off in Northampton County wind, or get damaged by falling river-ice and branches. Replacement runs $320-$580 depending on material and access. Stainless holds up better against Williams’s wet winters than galvanized. We stock common sizes and can fabricate custom covers for odd flue dimensions on colonial-era chimneys. Most replacements are done in under two hours.
Crown Repair
This is where Williams’s climate does its worst damage. The crown is the concrete or mortar wash that seals the top of your chimney where the flues pass through. River-valley humidity penetrates the masonry, freezes, and spalls the surface. We’ve repaired crowns on stone farmhouses off Route 611 where the mortar was crumbling so badly that a new cap would have leaked within a season.
Crown repair runs $450-$720. We use professional-grade crown coating materials, not the thin brush-on sealers sold at hardware stores. The crown has to be sound before any cap will protect it.
Crown Coating
For crowns with minor cracking but intact structure, coating extends life five to ten years at $380-$550. We use HeatShield and other professional-grade elastomeric formulations that flex with freeze-thaw movement. On a recent job near Easton Road, we coated a crown that had hairline cracks throughout but solid base masonry. The homeowner avoided a full rebuild and got a documented warranty.
Multi-Flue Cap
Williams’s historic farmhouses often have two, three, or four flues in a single massive stack. A multi-flue cap covers the entire chimney top with one screened structure, keeping rain and animals out of all openings simultaneously. These run $520-$890 depending on stack dimensions and material.
Here’s the critical part: many of these old stacks have sealed secondary flues - summer kitchen or bake oven openings finished over a century ago. Our Chimney Cap & Crown team has found these hidden chambers tapped for wood stoves or gas logs without permits, creating venting hazards no standard cap can address. We map every opening with camera inspection before recommending any cover.
Custom Cap
Colonial-era chimneys in Williams don’t always match modern standard sizes. We fabricate custom stainless and copper caps for odd dimensions, decorative requirements, or heritage preservation needs. Custom work starts around $680 and is typically completed with a single site visit for measurement and a second for installation.

Common Chimney Cap & Crown Problems We See in Williams Homes
- New cap installed on a crumbling crown. River-valley fog and freeze-thaw cycles spall mortar joints and brick faces around the crown wash faster than in drier western Lehigh Valley. A cap set on bad masonry leaks within a season. We inspect the crown first, repair or coat it if needed, then install the cap. Done right - and we stand behind it.
- Hidden sealed flues creating venting hazards. On stone farmhouses off River Road, we regularly find secondary flues - originally serving summer kitchens or bake ovens - that were sealed decades ago and later tapped for appliances without permits. A standard multi-flue cap fitted over both openings can silently recirculate exhaust into living spaces. Camera inspection finds what visual inspection cannot.
- Oversized flue chambers drafting poorly with modern inserts. Original multi-flue chambers were built for cooking hearths, not EPA-certified wood stoves. A cap installed to “fix” a smoking chimney masks a flue-sizing problem that only camera inspection reveals. We measure, document, and explain before selling any hardware.
- Efflorescence and spalling from Delaware River humidity. Williams’s position in the river valley means persistent moisture penetration that inland Northampton County communities don’t experience at the same severity. White mineral staining on exterior brick, flaking mortar, and spalled brick faces are early warnings that the crown is failing and needs attention before water enters the structure.

FAQs - Chimney Cap & Crown in Williams
A multi-flue cap is usually the better choice for Williams’s older farmhouses, provided both flues are properly vented and documented. Two separate caps leave gaps where rain and animals can enter between them, and they don’t protect the crown wash between flues. The critical step is camera inspection: we’ve found sealed secondary flues in River Road stacks that homeowners didn’t know existed. Once we map every opening, we can size a multi-flue cap correctly or fabricate a custom cover. Call (610) 756-1504 to schedule - estimates are free.
You see the camera footage yourself, and you get a plain-English verdict with no pressure. We don’t recommend caps, crowns, or any repair without photo documentation you can examine. On a recent job near Easton Road, we ran a Level 2 inspection and found the flue was sound - the homeowner just needed a $320 cap, not the $4,000 liner another company had proposed. Photos you can see, a plain-English verdict. That’s how we work.
Your chimney was built for a cooking hearth or fireplace with a much larger flue than your insert requires. The mismatch creates sluggish draft and rapid creosote buildup. A cap won’t fix this. In Williams’s River Road farmsteads, we regularly see inserts vented into original oversized chambers that were never designed for them. Our camera inspection measures the actual flue dimensions against the appliance specifications. Sometimes a properly sized liner is needed. Sometimes a custom cap with engineered draft characteristics helps. We show you the numbers and let you decide. Call (610) 756-1504 for an exact assessment.
The crown is the concrete or mortar layer that covers the top of your chimney around the flue openings, shedding water away from the masonry below. Williams’s Delaware River valley location traps persistent moisture and fog against chimney tops, while cold Northampton County winters drive repeated freeze-thaw cycles. Water penetrates micro-cracks, expands when frozen, and spalls the surface. We’ve seen crowns in Williams deteriorate twice as fast as identical construction in drier, more sheltered locations west of the Lehigh River. Annual inspection catches this early; crown coating or repair prevents the structural damage that leads to full rebuilds.
Stop using the appliance until a Level 2 camera inspection determines where that flue leads and whether it’s properly vented. On a stone farmhouse off River Road, our tech ran a camera down what the homeowner believed was a single wood-stove flue and found a second, sealed chamber behind it - capped decades ago, still tied into the original oversized stack. We coated the failing crown and set a custom multi-flue cap over both openings with a screened secondary port, then documented the whole run on camera so the owner could see exactly why the draft had been so poor. The wood stove now pulls cleanly and the hidden chamber is permanently vented, not walled off. Call (610) 756-1504 - this is not a guesswork situation.
