Gelco Chimney Cap & Crown in Bethlehem: What to Know First

We provide independent Gelco chimney cap and crown service in Bethlehem, with most Gelco cap replacements and crown repairs completed in a single visit and priced upfront before we start. A standard Gelco single-flue cap installation runs $285-$425 in the Bethlehem market, while crown coating or repair typically falls between $340-$620 depending on accessibility and how far the damage has spread. If it needs doing, we’ll tell you. If it doesn’t, we’ll tell you that too.

This page is for Bethlehem homeowners who already own a Gelco cap or crown and need someone who knows the product line, not a generalist who’ll swap in whatever fits. We are an independent Gelco service provider - not affiliated with or authorized by Gelco - and we’ve been working on their products since they became common in Pennsylvania homes through the 1990s and 2000s. Call (610) 595-5754 to speak with a live person, any hour.

How Gelco Products Fail - and How We Fix Them

• Gelco Single-Flue Caps (Model A and B Series): The 304 stainless mesh on older A-Series units installed across Bethlehem’s South Side and West Bethlehem neighborhoods has a known tendency to separate at the weld points after 12-15 winters of freeze-thaw cycling. Our fix is fabricating a custom-fit replacement mesh panel or sourcing the correct Gelco-compatible aftermarket cap rather than forcing a generic unit that won’t seat properly on the original base.
• Gelco Multi-Flue Caps (Model C and D Series): The C-Series in particular develops a characteristic lid sag when the internal support struts corrode at the base, something we see regularly on the taller chimneys up around College Hill where wind load is higher. We replace the strut assembly with marine-grade hardware and reset the lid to original pitch so water sheds correctly instead of pooling.
• Gelco Crown Seal Coatings: Gelco’s brush-applied crown coating fails prematurely when applied over active hairline cracks without proper joint preparation, a shortcut we’ve found on several Bethlehem jobs where the previous contractor skipped the bonding step. We grind out the crack, apply a compatible elastomeric base coat, then finish with Gelco-specified material so the repair outlasts the warranty period.
• Gelco Base Pan Assemblies: The galvanized base pans on pre-2010 Gelco installations rust through at the corners first, especially on chimneys with marginal flue gas condensation issues common in Bethlehem’s older stone homes with unlined flues. We fabricate a stainless replacement pan or transition to a full Gelco-compatible cap system depending on what the camera inspection shows.
• Gelco Spark Arrestor Mesh: The fine-mesh spark arrestor required in some Bethlehem Township jurisdictions clogs with creosote more aggressively than standard mesh, and Gelco’s original fine-mesh design restricts draft when neglected. We clean or replace with an improved airflow design that maintains code compliance without the smoking fireplace complaints we’ve traced to this exact issue.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks our calendar, and books a window that works for you. No app, no callback tag.
2. 2
   Level-2 camera inspection. We run a camera up the flue before touching the cap or crown. You see the photos, we explain what we’re looking at, and we document the condition of the flue walls that the cap and crown are supposed to protect.
3. 3
   Parts decision. If your Gelco part is still in production, we quote OEM. If it’s discontinued, we source a quality aftermarket equivalent that matches Gelco’s gauge and fitment, or we fabricate from stainless stock in our shop. We tell you which route we’re taking and why.
4. 4
   The repair. Our techs arrive in uniform, work from ladder and roof protocols we’ve used for decades, and complete most Gelco cap and crown jobs in one visit. We don’t leave until the cap is secure, the crown is sealed, and water runs off the way it should.
5. 5
   Post-job test and documentation. We run the camera again if the flue was involved, show you the finished work, and leave a written report with photos. The 90-Day Done Right Promise goes into effect the moment we pack up.
6. 6
   Cleanup and closeout. We haul away the old material, sweep the roof and ground area, and review the invoice with you before you pay. The number on the estimate is the number on the invoice.
