Quick Fix, Big Protection

Yes, We Do That. Usually This Week.

Tell us what you're seeing (a rusted cap, a missing cap, birds in the flue) and we'll get you scheduled. If we're already sweeping or inspecting in your area, a cap swap often rides along on the same trip.

Small Part, Big Job

What a Good Chimney Cap Actually Does

Rain Protection

Keeps rain from running straight down your flue, where it rusts dampers, erodes mortar, and breeds that musty fireplace smell.

Animal Protection

Birds, squirrels, and raccoons love an open flue. The mesh keeps them (and their nests) out of your chimney for good.

Spark Arrestor

The spark arrestor screen stops hot embers from landing on your roof or a neighbor's yard. Standard on every cap we install.

Downdraft Control

On windy Oklahoma days a capless flue can push smoke back into the room. A properly sized cap tames downdrafts.

Prefab chimney? We replace rusted-out chase covers too, the flat metal pan that does a cap's job on factory-built chimneys.

Worth a Look This Week

Signs Your Cap Is Done (or Was Never There)

  • Rust streaks running down the chimney or staining the roof
  • A cap that's visibly crooked, loose, or rattling in wind
  • Chirping, scratching, or nesting sounds in the flue
  • Water in the firebox after rain
  • No cap at all: an open clay flue against the sky

From the ground it's a 60-second check. From up top, we'll confirm the flue size, fit the right cap, and secure it so Oklahoma wind can't take it.

Cap Questions

Chimney Cap FAQs

Do I really need a chimney cap?

If you want to keep rain, animals, and debris out of your flue, yes. An uncapped chimney takes on water every time it rains, and water is the number one thing that destroys chimneys in Oklahoma. It's the cheapest protection your chimney can get.

What does a spark arrestor do?

It's the mesh screen built into the cap that catches hot embers before they can escape onto your roof or into dry grass. The same mesh is what keeps birds and squirrels out, so one part does two jobs.

Can you match my chimney's look?

Yes. Caps come in stainless, black, and copper finishes and in single-flue, multi-flue, and full-coverage styles. We'll size it to your flue and pick a style that suits the house rather than a one-size-fits-all unit.

How fast can you install one?

Most chimney cap replacements are done in a single visit, and standard sizes are usually on the truck. If your flue needs a custom or multi-flue cap we'll measure on the first trip and install as soon as it arrives.
