Crested Butte Log Home Chinking
Professional chinking repair and re-chinking for log homes in Crested Butte, Colorado. At 8,909 feet in one of the snowiest, coldest corners of the state, your chink lines battle deep snowpack, sub-zero winter cold, and relentless freeze-thaw. We install flexible, certified Permachink and Sashco chinking systems that stay elastic below zero and keep your log walls sealed through the longest mountain winters.
What Crested Butte Winters Do to Your Chinking
Crested Butte is true deep-snow, extreme-cold country, and that is exactly what breaks chinking down. Three forces drive most chinking failure in the upper Gunnison Valley, and each one shapes how we seal your home.
Deep, Long-Lasting Snowpack
Snow stacks against the lower log walls and sits there for months. Every thaw drives meltwater into the joints and checks near grade, so the chink lines low on the wall fail first. We re-chink and seal those snow-buried joints to keep meltwater out of the wood.
Brutal Sub-Zero Cold
Winter nights in the upper Gunnison Valley plunge toward -30°F and below, contracting logs and sealants hard. Rigid or aged chinking cracks and pulls away from the wood. We install elastomeric chinking rated to stay flexible at extreme cold instead of shattering.
Freeze-Thaw & Snow-Glare UV
Bright sun and reflection off the snowpack break down chink lines on south and west walls, while repeated freeze-thaw works water into every gap, expands it, and pries the chinking loose. We use UV-stable, flexible products and pay extra attention to the sun-blasted faces.
Chinking is only one layer of protection. For the full picture of how we restore high-country log homes — media blasting, cold-rated staining, and check sealing — see our Crested Butte log home restoration page and our broader Gunnison County services.
The Chinking We Use in Crested Butte
We are certified installers of the two most trusted names in log home sealing. Both are chosen for one reason: they stay flexible and weather-stable through Crested Butte’s deep snow and sub-zero cold.
Permachink Synthetic Chinking
The original synthetic elastomer chinking — flexible, breathable, and backed by a 10-year warranty. We match it to your existing color and texture so repairs blend seamlessly into the rest of the wall.
Sashco Log Jam & Big Stretch
Log Jam stretches up to 500% and stays elastic from -40°F to 180°F — built for Crested Butte’s sub-zero winters and big seasonal swings. Big Stretch handles the narrower checks and gaps that open as logs move.
Energy Seal & Check Mate
For gaps under 1/2 inch and the deep checks that collect snowmelt, we use Energy Seal and Check Mate 2 — sealed and color-matched so they disappear into the finish and keep water out of the log.

How We Chink Crested Butte Log Homes
A chink line that lasts in deep-snow country is about preparation as much as product. Here is exactly how we seal an upper Gunnison Valley log home so it holds up to the snow and cold.
Inspect Joints & Checks
We assess every joint and every upward-facing check, pay close attention to the lower walls that sit in the snowpack, and strip out cracked, cold-damaged, or pulled-away chinking back to sound wood.
Clean & Install Backer Rod
Surfaces are cleaned and the correct-diameter closed-cell backer rod is set so the chinking bonds to the logs in two points only — the key to letting it stretch through Crested Butte’s deep-cold movement without failing.
Apply, Seal Checks & Tool
We gun in Permachink or Sashco at a controlled thickness, seal the open checks that collect snowmelt, and tool everything into a clean, consistent mortar-like line that sheds water and matches your home.
Cure & Final Inspection
We work within the short high-country window when temperatures let chinking cure properly, then inspect every run to confirm full adhesion and a weather-tight seal before the snow returns.
Tight Chinking, Warmer Home, Lower Bills
In Crested Butte, every open chink line and unsealed check is a path for sub-zero drafts, wind-driven snow, and meltwater to get into the home. Failed chinking drives up heating costs through the long winter and creates cold spots throughout the house. Re-sealing those joints is one of the highest-return maintenance projects an upper Gunnison Valley log home owner can make.
Beyond comfort and energy savings, sound chinking and sealed checks are what keep snowmelt out of the log wall — preventing the hidden rot, mold, and insect damage that turn a simple repair into a full restoration. Paired with weatherproofing and fresh UV-blocking stain, it forms a complete protective shell for your home.
Chinking Across the Upper Gunnison Valley
We bring our crews and equipment to Crested Butte and across the upper Gunnison Valley, sealing log homes throughout Gunnison County and the surrounding high country — including the ski-town second homes on Mt. Crested Butte and the cabins scattered south toward Gunnison and up toward Gothic.
Crested Butte Chinking FAQs
How much does log home chinking cost in Crested Butte?
Professional chinking in Crested Butte typically runs $8–$15 per linear foot depending on gap and check width, accessibility, and whether failed chinking needs to be removed first. Deep-snow access and high-elevation ski properties can affect the estimate. Use our cost calculator or call (970) 368-2308 for a custom quote.
Why does chinking fail so fast on Crested Butte log homes?
Crested Butte combines some of the deepest snow in Colorado with sub-zero winter cold and intense high-alpine UV. Snow sits against the lower walls for months and drives meltwater into the joints, while temperatures toward -30°F contract and crack rigid or aged chinking. Add relentless freeze-thaw and chinking that is not cold-rated simply pulls away from the wood.
What chinking do you use in Crested Butte?
We install certified synthetic elastomer chinking — Permachink and Sashco Log Jam — chosen because they stay flexible and weather-stable through deep snow and extreme cold. Log Jam stays elastic from -40°F to 180°F, so it stretches with the wood instead of cracking, and both products carry 10-year manufacturer warranties.
Do you seal the cracks (checks) in the logs too?
Yes. The lengthwise cracks that open as logs move — called checks — are a leading way snowmelt gets into Crested Butte log walls. We seal the upward-facing checks that collect water as part of the chinking process, using flexible products that move with the wood through the deep-cold swings and keep moisture out.
Do you service ski-town second homes and the surrounding towns?
Yes. Many of the log homes we seal are vacation and ski-season properties on Mt. Crested Butte and around Crested Butte South that sit empty between visits. We chink and seal throughout the upper Gunnison Valley — Crested Butte, Mt. Crested Butte, Crested Butte South, Almont, and down toward Gunnison — and offer scheduled care plans for absentee owners.
