Chimney Company in Boulder - Flat-Price Sweep, Findings in Writing

Chimney Company in Boulder, CO

Chimney repair in Boulder starts with the brick itself. The city’s pre-1900s Victorians and early-1900s bungalows sit on original single-wythe masonry chimneys that have been through coal, then wood, then often gas, and a century of freeze-thaw has left many of them with cracked mortar and a crown that no longer sheds water. That is the work we see most here, and it’s why a repair conversation in Boulder usually begins with what a camera finds inside the flue rather than what a sales sheet says. Call (855) 360-7080 and we’ll book a sweep, show you the evidence, and quote the fix in writing.

Why Boulder Homes Are Different

Altitude changes the maintenance calendar. At roughly 5,400 feet, Boulder gets a long heating season and heavy wood-burning, so creosote builds faster than homeowners expect. Then the intense spring sun and extreme freeze-thaw cycles go to work on the outside, cracking crowns and opening mortar joints that stayed sound in milder places. A chimney that looks fine in June can be taking on water by the next thaw.

The housing stock splits the work in two. The core of Boulder, around 80302 and 80304, is Victorian-era and early-1900s brick with original masonry chimneys, many converted from coal to wood and later to gas. The 1960s through 1980s ranches and split-levels in 80303 and 80305 often have prefab metal fireplaces, which need different sweeping tools and different repair logic. Terrain matters too: mature ponderosa pines near Chautauqua and Mapleton Hill drop needles onto caps and into flues, and wind funneling through Boulder Canyon packs that debris into the creosote. A fall cleaning here often means pulling a needle-and-soot plug from the smoke shelf.

Our Main Boulder Services

Most Boulder homeowners call us about one of two things: the annual sweep, or a repair a home inspector flagged.

Chimney Sweep in Boulder

In Boulder, a sweep is often a discovery job. We run the brush, pull the creosote, then put a camera up the flue, because in Mapleton Hill and Whittier the tiles are frequently missing altogether and the sweep is the first chance anyone has had to see the cracked mortar joints behind the soot. You get the photo report whether the flue is clean or not, and we tell you plainly when a finding can safely wait until next season. Book a chimney sweep before burning season starts and you’ll know exactly what you’re working with.

Dryer Vent Cleaning in Boulder

Lint buildup in a dryer duct is a fire hazard most chimney-only companies never touch, and it’s a real issue in older Boulder homes where the vent run is long, bends hard, or vents into a space that was never designed for it. We clear the full run and show you what came out, so you can see the difference between a normal lint load and a restricted duct. If your dryer takes two cycles to dry a load, that’s usually the sign. Ask about dryer vent cleaning when you book the sweep and we’ll handle both in one visit.

Chimney Repair in Boulder

Chimney repair in Boulder is shaped by two forces that rarely combine the way they do here: a century of original masonry and a freeze-thaw cycle that attacks it every spring. The brick Victorians and early-1900s bungalows in Mapleton Hill and Whittier were built with single-wythe chimneys and no clay flue tile liner, so what starts as a routine cleaning often turns up cracked mortar joints that need relining before the next heating season. We handle the whole flue, from that chimney repair through the structural work above the roofline, and we don’t recommend anything we can’t show you on camera.

Chimney Crown Repair

Signs you need it

A crown that’s cracked, crumbling at the edge, or pulling away from the flue is letting water straight into the masonry, which is the single most common cause of the spalling brick we find on Boulder roofs.

What it costs in Boulder

Crown repair typically runs $350 to $700, and a full crown rebuild typically runs $600 to $1,200, with the written estimate setting the final price once we’ve seen the top of the chimney.

How we do it

We remove the failed mortar, rebuild the crown with a proper slope away from the flue, and seal the joint so meltwater from spring snowmelt sheds instead of soaking in.

Chimney Liner Installation

Signs you need it

Missing or deteriorated flue tiles, cracked mortar joints visible on camera, or a flue that was sized for coal and never updated for a modern appliance all point to a liner that’s no longer doing its job.

What it costs in Boulder

Liner installation typically runs $2,500 to $6,000 depending on flue length and liner type, and HeatShield resurfacing, which restores a liner without full replacement, typically runs $1,200 to $2,800; the written estimate sets the final price.

How we do it

We measure the flue, insulate and install a DuraFlex flexible liner sized to the appliance, or resurface the existing tile with HeatShield where the damage allows it, then verify the fit with a camera pass.

Chimney Cap Replacement

Signs you need it

A rusted, bent, or missing cap is an open door for rain, birds, and the pine needles that drop heavy around Chautauqua and Mapleton Hill.

What it costs in Boulder

Cap replacement typically runs $250 to $650 including the cap and installation, with the written estimate setting the final price once we’ve confirmed the flue size.

How we do it

We pull the old cap, check the flue top for damage while it’s exposed, set a correctly sized stainless or copper cap, and secure it against the canyon winds that funnel through Boulder.

What Chimney Repair Costs in Boulder

Do I really need a new liner, or is that an upsell?

You need one when the camera shows missing tiles or open mortar joints, and you don’t when it doesn’t. We show you the footage and tell you plainly if the flue can wait a season. Call (855) 360-7080 for an exact quote.

Can chimney repairs in Boulder be done the same day as the sweep?

Often yes, for caps and minor crown work we carry the materials for. Liner installation gets booked as its own job once the measurement is confirmed. Call (855) 360-7080 and we’ll lay out both timelines.

Brands We Service in Boulder

We install and work with professional-tier products from HeatShield, DuraFlex, Copperfield, and Famco, and we name them because you deserve to know what’s going into your home. Those aren’t hardware-store substitutes, and we claim no stocked parts: each component is ordered for your job. Turnaround is typically a few days from the written estimate. See our brands for the full roster.

Neighborhoods We Serve in Boulder

We work across Boulder, from the brick streets of Mapleton Hill and Whittier to the ranches and split-levels out toward 80305. The housing era changes the job more than the address does, so a Whittier Victorian and a Table Mesa ranch get different tools, different inspection priorities, and sometimes a different answer about whether a repair can wait. One response note for the whole city: we book sweeps into the next open slot and confirm the window when you call. We answer 24/7, and calls outside dispatch hours are booked into the next opening, Sunday through Friday, 7am to 7pm.
