What a Chimney Cap Prevents
Rain entering an uncapped chimney causes rapid liner deterioration, rust on the damper, and water stains on the firebox. Animals — particularly birds, squirrels, and raccoons — nest inside uncapped chimneys. A proper cap with mesh prevents all of this while still allowing smoke to draft freely.
How Our Chimney Cap Installation Works
Simple, professional, and mess-free from start to finish.
Measurement
We measure the flue opening(s) and chimney crown for exact fit.
Cap selection
We recommend the right style — single-flue, multi-flue, or full-width coverage.
Old cap removal
Existing damaged cap is removed and the crown is inspected.
Cap installation
New cap is anchored securely to the crown or liner top.

We verify the screen mesh meets spark arrest requirements.

What Homeowners Are Saying
ChimmerJim was at my house within 24 hours. They cleaned the full flue, found a cracked tile I didn't know about, and gave me a clear repair quote. Professional from start to finish.
David M.

Used them for a Level 2 inspection before closing on our home. The report was detailed with photos and the inspector was patient explaining everything. Highly recommend.
Sarah K.
Washington, DC
Fast, clean, and honest. No upsells, no scare tactics — just a thorough sweep and a real inspection. The price matched the quote exactly. Will use every year.
Mike T.

My gas fireplace had a pilot light issue. ChimmerJim diagnosed it immediately, replaced the thermocouple, and had it working the same visit. Great service.
Jennifer L.
Austin, TX
Crown was cracked and leaking water into the firebox. They repaired it in one afternoon and applied waterproofing. Two years later, still no leaks.
Robert W.

I scheduled a dryer vent cleaning after noticing clothes taking forever to dry. After ChimmerJim came out, the difference was immediate. Should have done this years ago.
