Wilmington, DE · Chimney Sweep
A chimney sweep removes the soot and creosote that build up inside the flue every time you burn. It lowers the risk of a chimney fire and helps the fireplace draw properly.

The work
We protect the room with drop cloths and run a sealed vacuum while we brush the flue from top to bottom. The smoke shelf, smoke chamber and firebox are cleaned too.
Every sweep includes a look at the flue, damper, crown and cap, with photos of anything that needs attention. If the creosote is glazed and won't brush out, we explain the options before doing anything more.
See the full chimney sweep page for every detail of the work.
Why it matters here
Delaware has humid summers, coastal storms and winters that swing above and below freezing.
Salt air and wet winters wear out metal caps and flashing, and the freeze-thaw cycle works on the mortar joints.
