An uncapped flue is an open pipe to the sky. Rain and snow fall straight in. Birds and squirrels move in. Leaves collect. In dry Colorado conditions, an uncapped or unscreened flue also does nothing to arrest sparks.
A cap is one of the least expensive components on a chimney and prevents some of the most expensive problems. We install caps sized and anchored correctly for the flue, repair loose or damaged ones, and replace caps that have rusted through.

Wind works fasteners loose — a particular issue in Front Range and foothill communities that see strong gusts. Corrosion eats through lighter-gauge metal. Heavy creosote can clog spark screens on wood-burning systems, choking the draft. And undersized, poorly attached caps simply blow off.
Stainless and heavy-gauge steel caps matched to the flue size, with mesh screening to keep animals out and help contain sparks. Multi-flue and custom caps for chimneys with more than one flue. Proper mechanical anchoring so Colorado wind doesn't take it back off.
These services often go hand in hand with chimney caps:
Strongly recommended. It's the simplest protection a chimney has against water, animals and debris — and screening helps contain sparks.
That's creosote — a sign the wood-burning system needs cleaning, not just a cleaner screen. The clogged screen is the symptom.
Yes. Multi-flue caps cover both openings under one cover and are a common, tidy solution.
