Chimneys Built to Takethe WindBroomfield chimney sweeping, repair and masonry for Superior, Louisville, Lafayette, Westminster and east Boulder County
When chinook winds come down off the Flatirons, they can rip off chimney caps, peel back flashing and push smoke straight back into the house. Dry, windy winters raise the stakes on loose embers too. Interlocken Chimney & Masonry keeps north-metro chimneys sealed, capped and burning safely, and we answer the phone at 3 AM as readily as at 3 PM.

How a windstorm hits a chimney
Caps blown off or bent
Loose screws and light caps go first. Without one, snow, birds and rain head straight down the flue.
Peeled-back flashing
Gusts get under the metal where the chimney meets the roof. The next storm brings a ceiling stain.
Loose top bricks
Years of wind and freeze-thaw loosen the top courses. They can fall in the next big gust.
Smoke pushed back inside
Strong wind across the chimney top creates downdrafts. A wind-directional cap usually fixes it.

Wildfire season is year-round
Keep the sparks inside the chimney
The December 2021 Marshall Fire showed how fast wind-driven fire moves through grassland neighborhoods in Superior and Louisville. A chimney can't stop a wildfire, but it shouldn't add embers on a dry, windy night either.
Spark arrestor screens
Mesh sized to catch embers while letting smoke out, in the openings building code calls for.
No burning on red flag days
When fire danger is high, skip the wood fire. Gas fireplaces don't throw embers.
Clear the roof
No dry leaves or branches near the chimney top or in the gutters below.
Ashes in metal cans
Fireplace ash can hold heat for days. Store it outside in a lidded metal can, away from the house.

After a windstorm
Four checks before your next fire
Look from the ground first. Never climb onto a roof in the wind. If anything looks off, call us.
CHECK 1
Cap still there?
From the yard, look for a missing or tilted cap and mesh.
CHECK 2
Bricks on the roof?
Brick bits or mortar on the shingles or in the gutters mean the top is coming loose.
CHECK 3
Stains inside?
Look at the ceiling and walls by the chimney for new water marks.
CHECK 4
Draft test
Light a small fire. Smoke spilling into the room means call before using it again.

Assess, secure, repair
Typical drive times from 11120 Broomfield Ln. High winds, snow and US-36 traffic can stretch them, so you'll get a live ETA on the phone.
Do you pick up at night and on holidays?
Yes, around the clock, including weekends and holidays. Emergencies like a cap torn off in a windstorm, water coming in or smoke filling a room can get a crew out at any hour.
Can chinook winds really damage a chimney?
They can. Strong downslope gusts can tear off caps, lift flashing and loosen the top rows of brick, especially on chimneys whose mortar is already worn. A quick check after a big wind event catches problems before the next storm.
What is a spark arrestor, and do I need one?
It's a metal mesh screen built into the chimney cap that catches embers before they leave the flue. The residential code sizes the openings so they block anything larger than 1/2 inch while still letting smoke out. On wood-burning chimneys in dry, windy areas, it's a smart upgrade.
Why does my fireplace smoke when it's windy?
Wind blowing across the top of the chimney can push air back down the flue. A wind-directional cap, a taller flue extension or fixing a nearby roof obstruction usually solves it.
My home is new. Does the gas fireplace need service?
Yes. New direct-vent units often leave a film on the glass after the first season, and pilots, gaskets and vent terminations should be checked every year for safe operation.
Do you document storm damage for insurance?
We do. You get dated photos, notes on what failed and a repair estimate you can send to your homeowners insurer.
Which towns do you cover?
Broomfield and Anthem, Superior, Louisville, Lafayette, Erie, Boulder and Gunbarrel, Westminster, Arvada, Thornton, Northglenn and Federal Heights.
