Regular chimney sweeping is the single most important step you can take to prevent chimney fires. At Summit Chimney Co, our certified sweeps remove all levels of creosote accumulation — from light deposits to the dangerous glazed third-degree buildup — along with bird nests, leaves, and debris that block airflow. We use professional-grade rotary cleaning systems combined with high-efficiency HEPA vacuums so your home stays clean throughout the process. Boulder's cold seasons mean your fireplace puts in serious hours, which accelerates creosote formation faster than many homeowners expect. We recommend annual cleaning for wood-burning appliances and inspect every flue we touch. After every sweep, you receive a written condition report detailing exactly what we found and what, if anything, needs attention next.

Level 1 is ideal for annual maintenance checks on chimneys with no known changes. Level 2 is required when you've purchased a new home, changed your heating appliance, or experienced a chimney fire — and includes a thorough video scan of the flue interior. Level 3 involves selective demolition to access concealed areas when serious hazards are suspected. Boulder real estate moves fast, and we work efficiently with buyers, sellers, and agents to deliver timely inspection reports. Every inspection comes with a written summary, photographic documentation, and honest recommendations — so you can make informed decisions, not pressured ones.

Water infiltration through a cracked chimney crown, deteriorating mortar joints, or a missing cap can cause damage that compounds season after season. Our masonry technicians diagnose the root cause before recommending any repair — never the reverse. We rebuild crowns, repoint mortar joints, replace damaged bricks, and apply professional-grade waterproofing sealants that breathe while repelling moisture. Every repair we perform is backed by a written warranty, so you're not left wondering whether the work will hold through the next hard winter. We also restore historic stonework and older masonry with materials matched carefully to the original, preserving your home's character without sacrificing structural integrity.

Cracked, deteriorated, or incorrectly sized liners are a leading cause of house fires and carbon monoxide intrusion. Summit Chimney Co installs industry-leading stainless steel flexible liners and rigid liner systems, as well as cast-in-place poured liners for older or irregularly shaped masonry chimneys. All liner work meets or exceeds local Boulder building codes and manufacturer specifications. We size every liner to your specific appliance — whether a wood stove, gas insert, or oil furnace — to maximize draft efficiency and minimize dangerous condensation. Every installation includes a written manufacturer warranty plus our own labor guarantee, giving you complete peace of mind.
Request this service →A missing or damaged chimney cap is an open invitation for water, raccoons, squirrels, and starlings to enter your flue — and all of them do, regularly, in Boulder. Summit Chimney Co supplies and installs stainless steel and copper chimney caps custom-fitted to your flue size and crown configuration, providing reliable weather and animal exclusion for the life of your chimney. We also install and replace throat dampers and top-mount energy-saving dampers that seal far more effectively than traditional cast-iron throat dampers, reducing heated air loss in winter and cooled air loss in summer. A properly functioning damper can noticeably lower your energy bills. All cap and damper installations are completed in a single visit with no callbacks needed — just lasting, properly fitted hardware.

Lint accumulates in your dryer's exhaust duct every single cycle, gradually restricting airflow until drying times spike, energy costs climb, and the risk of ignition becomes very real. Summit Chimney Co cleans dryer vents using flexible rotary brush systems that fully clear the duct from appliance to exterior termination, regardless of length or number of bends. We also inspect the duct material, check for improper terminations, and test post-cleaning airflow. If your clothes are taking two cycles to dry, your dryer is running hot, or it's simply been more than a year since your last cleaning, it's time to call us. We complete most dryer vent cleanings in under an hour with no mess left behind.
