Gelco Chimney Cleaning in Shorewood, WI
We provide independent Gelco service across Shorewood, from cap repair and replacement to waterproofing and crown work on the masonry chimneys that define this village. What sets our Gelco work apart here: we understand how these caps and components fail on Shorewood’s century-old, tightly packed homes, where lake-effect moisture and decades of gas venting wear on flues and crowns. Our technicians have up to 8 years of experience reading exactly those conditions. Call (855) 935-4194 for a free estimate.
Why Shorewood Residents Choose Us for Gelco Service
We know Gelco components well because we work on them constantly in this kind of housing stock. When a Gelco cap sits on a brick chimney along Oakland Ave, the fix isn’t the same as the fix on a newer home inland. The parts have to fit the crown, seal the flue tiles, and vent the appliance correctly, or the moisture problem just moves.
We’re an independent shop, not affiliated with or authorized by Gelco, so we recommend what actually fits your chimney rather than pushing a single product line. That matters in Shorewood, where chimneys come in odd shapes and old clay flues rarely match a stock size. We use quality parts that fit the job, and we tell you honestly when a cap can be repaired instead of replaced.
Scheduling is simple: tell us what you’re seeing, and we’ll book a visit. We answer 24/7 on the phone, with fast dispatch from 7am to 7pm, Sunday through Friday.

Common Gelco Chimney Cleaning Problems We Solve in Shorewood
Here are the Gelco failures we run into and how Shorewood’s climate and housing make them worse.
- Custom caps undersized for gas appliances. A lot of custom Gelco caps were sized when a chimney vented a wood-burning fireplace. After a conversion to gas, those caps lack proper ventilation for the new appliance, so moisture and acidic condensate build up inside and eat at the mortar around the flue tiles. That’s the internal damage a wood-only approach never catches.
- Rust at the weld points on stainless Gelco caps. Lake-effect moisture and the acidic condensate from high-efficiency furnaces work on stainless caps over time, and the seams are where corrosion starts. Once the welds go, the cap starts letting water past.
- Top-mount caps on uneven or spalling crowns. A Gelco top-mount cap set on a crown that’s already spalling won’t seal, and water gets underneath. In Shorewood’s freeze-thaw winters, that trapped water breaks the crown and flue tiles down faster each spring.
- Multi-flue caps that don’t seal around irregular tiles. Older chimneys here often have clay tile liners that aren’t perfectly round or even, so a multi-flue cap can leave gaps at the edges. Wind-driven rain finds those gaps and gets straight into the flue.
- Caps masking deeper water damage. A cap that looks fine on top can hide a cracked crown and degrading tiles underneath. On the lake-facing south and east faces, spalling brick and white efflorescence on the exterior are usually the first signs.
Gelco Service in Shorewood: What Local Conditions Mean for Your Equipment
Shorewood’s building stock is mostly pre-1940, and many homes still have their original clay tile flues that were never relined when the house switched to gas appliances. That combination is the single biggest thing shaping how a Gelco cap performs here. Those old flues weren’t built for the acidic condensate a gas furnace or water heater produces, and if the cap doesn’t vent the flue properly, that condensate sits on the clay and mortar and eats it from the inside. Drive down Oakland Ave and you’ll see the tell: white efflorescence blooming on the exterior brick of otherwise well-kept homes. It’s not a cosmetic issue. It’s moisture working its way out through the masonry after the inside has already started to break down. For Gelco owners, this is why correct cap ventilation and waterproofing matter more than the cap’s appearance, and it’s why we inspect the flue, not just the cap.
Gelco Models & Products We Service in Shorewood
We service the Gelco products that sit on and around Shorewood chimneys: Gelco Top Mount Chimney Caps, Gelco Multi-Flue Caps, Gelco Custom Caps, and Gelco Chimney Covers. Each one meets a different need, from a single wood flue to a multi-flue chimney with several appliances venting at once, and each fails in its own way.
When a part needs replacing, we use OEM Gelco parts when they’re available so the fit and function are right. For discontinued products, or when the OEM part costs more than makes sense, we’ll steer you to a high-quality alternative that fits. We’re an independent provider and can work with whatever best suits your chimney.

AfterGelco Service Pricing in Shorewood
Pricing is set per job by a written estimate, so what you see in the estimate is what you pay. The final cost depends on the cap type, the condition of the crown and flue tiles underneath, and whether we’re doing waterproofing or crown repair at the same time. A free estimate includes looking at the cap, checking the flue, and explaining what we find and what it takes to fix it. Here’s a general picture of what drives the number:
- Cap repair vs. replacement: Repair is usually the smaller job when the existing cap can be restored to safe working order.
- Crown repair and waterproofing: Adding these at the same visit is often more efficient than a separate trip.
- Flue condition: The condition of the tile liners underneath is what decides whether a simple cap job turns into something more.
We write one flat estimate before booking, so there’s nothing to guess at. Call (855) 935-4194 for an exact quote. Estimates are free.

FAQs – Gelco Chimney Cleaning in Shorewood
Rust at the seams of a stainless Gelco cap usually comes from lake-effect moisture combined with acidic condensate from a high-efficiency furnace or water heater. The two together attack the weld points faster than plain weather would, and once corrosion starts it opens gaps that let water in. We can assess whether the cap can be repaired or should be replaced.
Often it isn’t, because a cap sized for a wood flue typically doesn’t vent a gas appliance properly, and the condensate it traps damages the mortar inside. The safe move is to have the flue and cap checked for correct ventilation for the appliance now in use. Call (855) 935-4194 and we’ll take a look.
White efflorescence on the exterior brick, spalling mortar, or a crown that looks cracked are the usual signs that water is getting in around the cap. In Shorewood’s freeze-thaw climate, those signs show up on the lake-facing faces first. If you’re seeing any of them, it’s worth an inspection.
Usually yes, but the fit around old clay tile liners has to be measured carefully, since irregular tiles are where a multi-flue cap tends to leak. We check the tile openings and seal the cap properly so wind-driven rain can’t slip past the edges. Call (855) 935-4194 to book an assessment.
A sound, well-sealed crown with proper waterproofing is what keeps freeze-thaw cycles from splitting it, and a correctly vented cap keeps the moisture from building up underneath. Most of the damage we see starts at the crown seam. Call (855) 935-4194 for an exact quote. Estimates are free.
