The cap and crown are the first line of defense against weather, and in Allentown they take a beating. The freeze-thaw swings that roll through Lehigh County each winter are hard on concrete crowns — water seeps into a hairline crack, freezes, expands, and widens the gap until the crown spalls and lets water pour straight into the masonry. Older homes around the Old Allentown Historic District and Center City often have original crowns that were never sealed, while many West End and Cedar Park houses have galvanized caps that have simply rusted through after decades of exposure. Either way, the fix at the top is far cheaper than the water damage it prevents inside.
Deciding between a cap and a crown repair comes down to what's failing. A cap is the screened metal lid over the flue opening; it blocks rain, blocks birds and squirrels, and stops gusty downdrafts off the surrounding rooftops in neighborhoods like Midway Manor and East Side. A crown is the sloped concrete (or mortar) wash that covers the brick around the flue. If you're seeing animals or rain inside the firebox, you likely need a cap. If you're seeing cracks, crumbling concrete, or stains running down the exterior brick, the crown is the culprit. Often both get addressed in one trip, since they sit inches apart at the chimney top.
The trade-off worth knowing: a quality stainless steel cap costs more up front than a basic galvanized one, but it won't rust out in Allentown's wet winters, which makes it the better value over time. For crowns, a sealant or patch buys years on a crown with minor cracks, but a crown that's already broken into pieces needs a full rebuild rather than a band-aid. We'll show you what we find and lay out the honest options — a quick seal versus a rebuild — so you can choose based on the actual condition, not a guess. Homes near Rittersville, South Allentown, the Old Fairgrounds, and the Hamilton District all see us for this exact work.

Chimney Cap & Crown Service — questions, answered
How do I know if my Allentown chimney needs a new cap or crown?
If rain, leaves, or animals are getting into your flue, you likely need a cap; if you see cracked or crumbling concrete at the top or water stains on the brick, the crown needs attention. We confirm which during an on-site look in Allentown.
What does chimney cap and crown service cost in Allentown?
Our minimum service charge is $150. A standard stainless cap install typically runs $200-$450 and crown sealing $200-$500, with full crown rebuilds higher. The exact price is confirmed on-site before any work begins.
Why do crowns crack so often on Allentown homes?
Lehigh County's freeze-thaw cycles drive water into tiny cracks, where it freezes and expands, widening the damage each winter. Older crowns in areas like Center City and the Old Allentown Historic District are especially prone to this.
Can you stop animals getting into my chimney in Allentown?
Yes — a screened cap is the standard fix for keeping birds, squirrels, and raccoons out of the flue. We see this often on East Side and West End homes near the tree cover around Cedar Beach Park and Trexler Memorial Park.
Should I get a stainless or galvanized cap for my Allentown chimney?
Stainless steel costs more up front but resists the rust that wet Allentown winters cause, so it lasts far longer. Galvanized is cheaper initially but tends to corrode and fail, which is why most replacements we install are stainless.
