Chimney Work for the San Juans, Done Once and Written Down
Sweeping, caps and spark arrestors, and wood stove service across Durango, Cortez and Bayfield - one rate, firm price before we start.
Sweeping, caps and spark arrestors, and wood stove service across Durango, Cortez and Bayfield - one rate, firm price before we start.
Three services, one crew, and an honest answer about which one your house actually needs.
Creosote out, Level 1 inspection every visit.
Masonry chimneys, class-A insulated pipe, wood stoves and inserts. We sweep the flue, clean the firebox and smoke shelf, and inspect what the brush uncovers - then tell you plainly whether anything needs doing.
The part your insurer now asks about.
Stainless caps and code-compliant spark arrestor mesh, fitted and documented. This is the work that keeps embers out of your flue and rain off your crown - and the work that shows up on wildfire mitigation checklists in La Plata County.
Gaskets, baffles, glass and draft.
Stoves are consumables with a steel shell around them. Door gaskets flatten, baffles warp, firebrick cracks and glass glazes over. Sorted before the season, all of it is routine; sorted in January, none of it is.
Give us the basics and we will come back with a firm number, usually the same day. A photo of the chimney or the stove tells us more than anything you can type.
Three things shape chimney work in La Plata and Montezuma counties, and none of them is simply that it gets cold. The first is that most of the housing here is not on a natural gas main. Outside the town grid, heat comes from propane and wood, and wood does the heavy lifting on the cold end of the season. That is not a lifestyle choice about ambience - it is the heating system, run hard from October to April, and it deposits accordingly.
The second is elevation and the daily swing that comes with it. Durango sits at 6,500 feet, Cortez at 6,200, and both cross freezing and back most winter days rather than staying hard-frozen. Every one of those swings takes water that entered a crown crack or a failed mortar joint, freezes it and opens the gap slightly wider. Over two decades that is not weathering, it is slow demolition - and the crown is almost always where it shows first.
The third has nothing to do with weather. This is wildland-urban interface, and since the 416 Fire the insurance market has treated it that way. Colorado homeowner non-renewals rose 77 percent between 2018 and 2023 and have kept climbing, La Plata County has adopted the state's 2025 Wildfire Resiliency Code, and as of 1 July 2026 an insurer that prices your policy off a wildfire model has to tell you your risk score and credit the mitigation you have done. A sound cap and a compliant spark arrestor are on those checklists. That turns what used to be a small summer add-on into a reason to get on a roof in July.
Two counties, three towns, one rate - Cortez and Bayfield on scheduled route days.
Quoted before we start, and that is the number on the invoice. Nothing gets found halfway through that quietly doubles it.
A clean flue is a clean flue. Selling a sweep that is not due is how this trade earned its reputation, and we would rather keep the phone call than the invoice.
Photographs, measurements and a plain written finding, handed over whether or not you buy anything. Useful at insurance renewal and useful if you want a second opinion.
Cortez and Bayfield run on scheduled route days. Booking neighbours together is how the price stays the same 45 miles out as it is in town.
NFPA 211 asks for an inspection at least once a year and cleaning as the inspection dictates. A stove that heats a house through a Durango winter almost always earns an annual sweep. A fireplace lit a dozen evenings a season usually does not, and we will tell you that instead of selling you one.
Most single-flue sweeps with a Level 1 inspection run $190 to $290, depending on roof pitch and how much creosote is up there. Tall Victorian chimneys in town and anything needing rope access cost more. You get the number before we start.
It can. Since 1 July 2026 any Colorado insurer using a wildfire model to price or non-renew has to disclose your score and credit the mitigation you have actually done. A compliant spark arrestor and a sound cap are line items on those checklists, and we document the work so you have something to send them. We are not insurance agents and we cannot promise a discount - but you cannot claim credit for work nobody wrote down.
Both, plus Bayfield. Cortez is 45 miles west and we run it on scheduled route days rather than one-off call-outs, which is how we keep the price the same as in town. Say Cortez when you call and we will give you the next route date.
Worse, usually, and it surprises people. A flue that goes cold between visits condenses moisture every cycle and builds the tarry second-stage creosote that comes from cold starts, and nobody is there to notice a cap that blew off in April or a bird that moved in during June. Look before the first fire, not after.
September and October fill first. Cap and arrestor work is easiest in summer, while the roof is dry and there is no snow load on it.
