Professional Chimney Sweeping in Thornton, CO

We don't work an active wasp colony until it's treated. Once the colony is dealt with, we sweep and sanitize the contaminated flue and install a screened cap to seal the entry point.

A properly sized, properly screened cap is the number-one defense — it's the most common entry point we seal after an animal removal. We confirm the fit on the visit and pair it with the sweep so the system is both clean and protected.

Don't light it cold. Years of disuse means animals may have moved in, the cap or crown may have failed, the damper may be seized, and old creosote can have hardened. Book the $89 inspection first — we'll tell you exactly what condition the system is in, and the fee credits toward anything we fix in Thornton.

Book an inspection before the first fire. New-owner inspections are one of our most common calls — we tell you whether the chimney is safe to use as-is, what needs cleaning, what needs repair, and what the fuel type actually is if the seller's disclosure was vague.

Yes — we identify the fuel type, vent path, and appliance condition on arrival. Customers often book without knowing because the prior owner left no documentation; we sort it out on the visit and tell you what your specific system needs.

Same-day and next-day is our default, though peak burn-season weeks book up fastest. Message us your Thornton address and we'll give you the earliest realistic window so you're safe before you light it.
