Chase Covers That Guard Your Chimney Chase All Year

Prefab chimney chases need a properly fitted cover to prevent water from pooling around the flue opening and rotting the chase from the top down. We replace rusted or damaged chase covers with heavy-gauge stainless steel or galvanized units built to last.

Metal Chase Covers Take a Beating From KC Weather

A chimney chase cover sits at the top of a prefabricated chimney chase and acts as the primary water barrier between the interior chase structure and everything the Kansas City sky delivers – rain, sleet, snow, ice, and the temperature swings that go with them. It’s a flat or sloped metal panel that most homeowners never see and rarely think about until water shows up somewhere inside the house.
Galvanized steel chase covers – the type installed on most prefab chimneys during original construction – have a finite lifespan. The coating that protects them from rust eventually breaks down, and once rust sets in, the cover develops holes and seams that allow water to drain directly into the chase interior. From there, water works its way down to the firebox, the framing, and the ceiling surfaces below – and the repair costs grow with every season the cover is left in place.
Stainless steel and aluminum replacement covers solve the underlying durability problem that galvanized units can’t. A properly fitted stainless chase cover won’t rust, won’t warp under KC’s temperature extremes, and won’t need to be replaced every few years. For homeowners who’ve already dealt with one round of water damage from a failing chase cover, the upgrade to a corrosion-resistant replacement is simply the more practical long-term investment.

Stainless Steel Chase Cover Replacements Installed Across KC Metro

Every chase cover replacement we complete follows a process designed to ensure the new cover fits correctly, seals the chase completely, and holds up through years of Kansas City weather:
  • Existing cover removal and chase inspection to assess any water damage inside the chase structure before the new cover is installed
  • Custom sizing and fitting because prefab chimney chases aren't all the same dimension - an improperly fitted cover creates the same water entry risk as a rusted one
  • Stainless steel cover installation with all seams and edges properly sealed to prevent moisture infiltration at the perimeter of the cover
  • Flue cap condition check as part of the same visit - confirming the cap and cover are working together to fully protect the chase from above
  • Post-installation inspection confirming the cover sits flush, drains correctly, and leaves no exposed gaps around the chimney pipe
Our licensed chimney contractors serve Kansas City MO, Kansas City KS, Overland Park, and surrounding KC metro communities.
Why Choose Us

Protecting Your Prefab Chase From the Top Down

A rusted or improperly fitted chase cover turns into a direct water entry point for your entire prefab chimney system. Replacing it with the right material stops the deterioration cycle before it spreads further.

Custom-Fabricated Covers Fit Your Chase Exactly

Standard-size chase covers leave gaps that allow wind-driven rain underneath the edges. We fabricate covers to your chase’s exact dimensions – eliminating the fit problems generic replacements create.

Galvanized Steel Fails - Stainless and Aluminum Last

Factory-installed galvanized chase covers rust through and stain your chimney exterior within years. Upgrading to stainless steel or aluminum eliminates recurring replacement costs and protects the chase long-term.

Standing Water on Covers Means the Slope Is Wrong

Flat or low-pitch covers pool water directly against the flue penetration point. Properly sloped covers we install shed water completely away from every seam and edge.

Replacement Paired With a Full Chase Inspection

A deteriorated chase cover often signals water damage already developing inside the chase. Every cover replacement includes an assessment of the chase interior for existing moisture-related deterioration.
Chimney Parts & Components

Every Component Has a Role - Every Role Matters

A chimney is only as reliable as its weakest part. From the cap at the top to the damper inside, each component works together to keep your system safe, efficient, and protected.

Smoke Chamber

Sitting directly above the firebox, the smoke chamber compresses rising gases and directs them into the flue. When it's cracked or deteriorating, smoke enters your living space - we repair and parge smoke chambers back to a safe, sealed condition.

Chimney Liner

Every functional chimney needs a properly sized liner to contain heat, protect surrounding masonry, and vent combustion gases safely out of your home. We install clay tile, cast-in-place, and stainless steel chimney liner systems for all fuel types and flue configurations.

Chimney Cap

That small metal cap sitting on top of your flue does more work than most homeowners realize - blocking rain, debris, and animals from entering. We install durable, correctly sized chimney caps that fit your specific flue and hold up through every season.

Chase Covers

Prefab chimney chases need a properly fitted cover to prevent water from pooling around the flue opening and rotting the chase from the top down. We replace rusted or damaged chase covers with heavy-gauge stainless steel or galvanized units built to last.

Chimney Crown

The concrete crown sealing the top of your masonry chimney takes a constant beating from rain, ice, and sun exposure. Cracks in the crown let water into the chimney structure itself - we repair minor damage and pour full replacements when restoration isn't enough.

Chimney Flashing

Where your chimney meets the roofline is one of the most common entry points for water in the entire house. Poorly sealed or deteriorating flashing leads directly to interior leaks and structural damage - we reseal, repair, and replace chimney flashing built to hold.

Damper

A properly functioning damper controls airflow, keeps conditioned air from escaping when the fireplace isn't in use, and plays a key role in draft quality. Whether your damper is stuck, corroded, or missing entirely, we repair and replace chimney and fireplace dampers correctly.

Prefab Chimney

Factory-built chimney systems have a finite lifespan, and their components aren't interchangeable between manufacturers. We service, repair, and replace prefab chimney systems - including housings, caps, and liner sections - using the correct parts matched to your specific unit and installation requirements.

Gas Chimney Service

Gas appliances produce byproducts that accumulate inside the flue just like wood-burning systems do. Regular gas chimney maintenance keeps your venting clear, your draft functioning properly, and your household protected from the risks of carbon monoxide buildup and deteriorating liner conditions.

Built to Handle What Kansas City Weather Throws Overhead

Stainless steel chase covers outlast galvanized alternatives by years and eliminate the rust failure that makes cheap covers such a recurring maintenance problem. For Kansas City homeowners with prefab chimneys, the right cover is the simplest way to protect the entire chase system from the top down.

Stainless Steel Eliminates the Rust Failure Cycle Completely

Unlike galvanized covers that rust through within years, stainless steel chase covers resist corrosion indefinitely – ending the cycle of replacement and water damage repairs that failing covers create.

Custom-Fitted Covers Leave No Gaps Around the Chimney Pipe

A chase cover sized and fitted for your specific chimney seals completely at every edge – eliminating the water infiltration paths that improperly fitted or generic covers leave behind.

Protects Chase Framing and Interior From Long-Term Moisture Damage

Once water enters the chase, it attacks framing, insulation, and the firebox below. A sound cover keeps that moisture out from the first rainfall forward, protecting everything underneath it.

Combining Cap and Cover Service Maximizes Full Top Protection

Having both the chase cover and chimney cap addressed at the same visit ensures total coverage at the top of the chimney system – no gaps, no overlooked entry points for water.

Helpful Chase Cover Resources Published for Kansas City Homeowners

Why a Properly Fitted Chase Cover Matters More Than Most KC Homeowners Expect

Durable chimney chase cover installed in Kansas City residence
A chase cover isn’t something you size by guesswork. Prefab chimney systems across Kansas City come in varying chase dimensions, and a cover that doesn’t fit correctly leaves gaps where water, debris, and animals enter – quietly causing damage to the interior of the chase long before any visible sign appears outside.
Chimney KS measures every chase opening precisely before fabricating or sourcing a replacement cover. Standard stock sizes rarely account for the actual dimensions of an older or custom-built chimney chase, which is why a correctly fitted chimney chase cover installation starts with accurate field measurements taken directly at the roofline – not estimated from ground level.
We work with stainless steel and galvanized options depending on the system, budget, and how the chase cover needs to interact with existing chimney cap installation hardware already in place. Stainless steel is the stronger long-term choice for Kansas City’s seasonal weather swings, resisting rust and warping where galvanized covers typically fail within a few years of installation.
Where the existing chase cover has already failed – rusted through, caved inward, or pulling away from the chase walls – we remove the old cover completely, inspect the chase top and surrounding prefab chimney services components for water damage, and install the replacement with proper overhang and sealed edges. Every finished installation is checked before we leave the roofline to confirm the fit is tight and the chase interior is fully protected going forward.

Browse honest feedback from homeowners across Kansas City MO, Kansas City KS, and the surrounding metro who trusted our team to replace or repair their chimney chase covers.
Prefab fireplace chase had been letting water in for two seasons and we kept assuming it was the roof. Finally had the chase cover inspected and the galvanized sheet metal had rusted through in two places. Replaced with a stainless steel cover that fits the chase opening correctly and the water problem stopped immediately. Should've looked up sooner.
Vera CallowayWeatherby Lake, MO
Stainless chase cover installed, fits perfectly, no more water intrusion. Quick job handled professionally.
Dale HortonPlatte Woods, MO
Never knew what a chase cover actually did until the tech explained it during an inspection. The chase enclosure on our prefab system had been sitting open to the elements because the original cover had blown off at some point - probably years before we bought the house. Rain, debris, and a significant amount of moisture damage inside the chase were all traceable to that one missing component. New stainless cover custom fitted and the chase has stayed completely dry through every storm since.
Josephine Randall Lake Waukomis, MO
Old cover corroded and warped. New stainless one installed same visit. Chase stays dry now. Simple fix, real result.
Reggie LaffertyGardner, KS
The rusting chase cover had been staining the painted chase exterior with brown streaks for a few years - something I'd assumed was just weathering. Replaced with a properly fitted stainless cover that overhangs the chase walls correctly and the staining stopped. Room also noticeably drier near the fireplace wall that first winter. Small component, bigger impact than expected.
Ada WhitlockBasehor, KS
Cover replaced, chase sealed properly, no issues since. Good straightforward work.
Marcus SinclairDe Soto, KS
What the tech pointed out that I hadn't considered was the importance of the drip edge overhang on the cover design. The original cover sat nearly flush with the chase walls which meant water tracked directly down the side of the chase instead of draining away. New cover has a proper overhang that directs water clear of the structure. That design detail is what separates a cover that works from one that technically covers the opening but still lets water cause problems.
Thelma SolisLansing, KS
Chase cover rusted through, water getting in, fixed correctly. That's the whole story.
Pete Horton Spring Hill, KS
Had a raccoon access the chase through a gap where the original cover had partially lifted at the corner. Animal removed, cover replaced with a properly secured stainless model, chase inspected for damage. Tech made sure the new cover was secured in a way that couldn't be lifted or shifted by wildlife. Appreciated that level of thinking about the installation rather than just dropping a cover on top.
Lorraine DupreeEdgerton, KS
Fast turnaround, correct fit, stainless material for longevity. Chase cover done right.
Clarence KowalskiBuckner, MO
Moisture inside the firebox had been a mystery for two years. Roofer checked the flashing, chimney sweep checked the cap - neither one identified the problem. This company looked at the full chase assembly and found the cover had a failed seam along one side that was funneling rainwater directly down the interior chase wall. New custom-fitted cover installed and the moisture problem resolved completely. Worth having someone who looks at the whole system rather than just one component.
Ruth DrummondOak Grove, MO
Original galvanized chase cover, twenty-some years old. Tech showed us what Midwest weather does to galvanized sheet metal - corrosion throughout, a rusted-through section, standing water marks inside the chase. Replaced with properly sized stainless, correct overhang and fastening. Chase dried out within weeks. Good baseline repair that made everything else possible.

What KC Homeowners Need to Know About Chase Covers

Rust stains running down the side of the chimney chase, water intrusion in the firebox, damp or staining on ceiling surfaces near the chimney, and visible rust or holes on the cover itself are all clear indicators. Any one of these warrants an immediate inspection to assess the extent of damage before the next rain event.
In most cases, no. Rust on a galvanized chase cover is a structural failure – not a surface issue that patching materials can reliably address. A new stainless steel cover is the correct solution, and it’s typically more cost-effective than attempting to extend the life of a cover that has already begun allowing water infiltration.
No – they serve different purposes. A chase cover is the flat or sloped panel that covers the top of a prefab chimney chase, while the chimney cap sits directly on the flue pipe and prevents rain, animals, and downdrafts from entering the flue itself. Both components need to be in good condition to fully protect the chimney from above.
Chase covers are not one-size-fits-all. The correct cover dimensions depend on the exterior measurements of your specific chimney chase – and getting those measurements accurate is critical for a cover that fits flush and seals completely. Our team measures on-site before ordering any material to confirm the right fit.
Yes – we provide custom-fabricated stainless steel chase covers for prefab chimneys that fall outside standard dimensions. Non-standard chase sizes are more common than most homeowners expect, particularly in older Kansas City homes where original construction used non-typical chimney chase proportions.
