Quick AnswerEvery open flue should have a cap - it's the single most cost-effective way to protect a chimney. We measure your flue and custom-fit a stainless steel cap that seals out rain, blocks birds and squirrels, and stops downdrafts, rather than selling you a generic size that rattles loose or leaks around the edges.
What’s Included
A chimney cap looks simple, but a poor fit causes more problems than no cap at all. We measure every flue on site and fabricate or select a cap sized to that exact opening, then mount it so it can't work loose in Cleveland's wind and ice. Every installation includes a written estimate before we climb the ladder, so there's nothing to negotiate after the fact.
- We measure each flue individually rather than guessing from a catalog size, so the cap seats flush and doesn't gap, rattle, or leak around the edges during heavy rain or lake-effect wind.
- Caps are fabricated from 304 or 316 stainless steel, which resists the rust and corrosion that eats through galvanized big-box store caps within a few winters.
- Mesh sizing is set to keep out squirrels, raccoons, and nesting birds without restricting draft, and multi-flue caps are sized correctly when a single chimney vents more than one appliance.
- Mounting hardware is stainless as well, fastened to the crown or flue tile rather than relying on adhesive alone, so the cap stays put through freeze-thaw cycles and high wind events.
- We inspect the crown and flue tiles while we're up there and flag any cracking or deterioration before it turns into a bigger repair, since a cap can't fix a damaged crown underneath it.
- Every job includes a written, flat-fee estimate before installation begins - no surprise add-ons once the ladder's against the house.
Signs You Need This
- Rain stains or water dripping down the inside of the firebox or flue
- Scratching, chirping, or rustling sounds coming from the chimney
- Leaves, twigs, or debris visible when you shine a light up the flue
- No cap at all, or a bent, rusted, or ill-fitting one from a previous owner
- A smoky smell after rain, which often means water is pooling instead of draining
Our Process
On-Site Measurement
We measure the flue opening (or each flue, if there's more than one) and check the crown for cracks before recommending a cap size or style.
Written Estimate
You get a flat-fee, written quote on the spot - the price you see is the price you pay, with no hidden add-ons after we're on the roof.
Custom Fit and Mount
We fabricate or fit the stainless cap to your exact flue dimensions and anchor it securely to withstand Cleveland winters and lake winds.
Final Walkthrough
We show you the finished install, confirm the mesh and seal are secure, and note any crown or flashing issues we spotted for the future.
How Much Does It Cost?
Cap installation cost depends mostly on how many flues you have and whether the crown needs repair before the cap goes on - a single-flue cap is a straightforward job, while multi-flue or custom-shaped chimneys take more fabrication. We always provide a flat-fee written estimate after the on-site measurement, before any work begins, so you know the exact cost up front. There's no hourly billing and no charge that shows up after the fact. Most installations are completed same-day.
FAQs
Yes. An open flue is an open invitation for rain, birds, squirrels, and debris, and it's one of the most common causes of avoidable chimney damage we see in Cleveland homes. A cap is inexpensive compared to the water or animal damage it prevents.
Off-the-shelf caps are built to generic sizes and often don't seal tightly against an irregular or slightly out-of-round flue. A loose-fitting cap can blow off in a storm or let water in around the edges, which defeats the purpose.
A properly fitted 304 or 316 stainless cap typically lasts decades with no maintenance beyond an occasional inspection. It won't rust through the way galvanized steel does after repeated exposure to Cleveland's winters.
