A County That's Already Seen the Worst Case
Most fire damage calls trace to ordinary residential causes: an unattended stovetop, an overloaded circuit, a dryer vent overdue for cleaning. But Boulder County is also home to the most destructive wildfire in Colorado's history. On December 30, 2021, the Marshall Fire ignited in dry grassland and, driven by winds gusting past 100 miles per hour, destroyed more than 1,000 homes in Louisville and Superior within a matter of hours, one of Longmont's own listed service areas among them. A Louisville police officer who responded that day later said plainly that had firefighters not caught the fire when they did, it would have pushed on toward Longmont and possibly as far as I-25.
Longmont itself served as an evacuation point that day, with Rocky Mountain Christian Church opening as a shelter for families fleeing the fire. That proximity is part of why we treat wildfire and grassfire exposure as a genuine planning consideration here, not an abstraction.
Everything That Keeps Happening Once the Fire's Out
Soot carries a mild acidity that keeps degrading hardware, glass, and paint for as long as it's left sitting. Meanwhile, the water crews used to knock the fire down, potentially hundreds of gallons, is already working its way into subfloor and wall cavities. Getting a structure boarded up, tarped, and properly assessed happens the same day we're called, never pushed to whenever there's an opening.
Two Fires, Two Different Cleaning Approaches
A hot, fast-burning fire generally leaves behind a dry, powdery soot that a HEPA vacuum and the right sponge lift without much trouble. A slow, smoldering fire is a different animal entirely, leaving an oily film that smears and pushes deeper into a surface if attacked with the wrong method first. Reading which type we're dealing with before any cleaning begins is what keeps the situation from getting worse before it gets better.
Why Rebuild Waits on a Number, Not a Guess
Drywall doesn't go back up over framing until a documented moisture reading confirms it's actually safe, since closing up too early just hides a mold problem instead of preventing one. Structural framing that took fire damage gets signed off by a licensed engineer before rebuild starts. You'll have a written scope before any demolition and photo records of what came out, in the format Colorado adjusters actually expect to see on a fire claim.
Deciding What's Actually Worth Trying to Save
Smoke exposure doesn't ruin everything it touches, and it doesn't spare everything that looks fine either. We go through a space item by item: hard, sealed surfaces and many fabrics clean up completely with the right process, while soft, deeply porous items that took on heavy smoke sometimes can't be brought back no matter the effort.
When the Smell Outlasts a Clean-Looking Room
A space can pass a visual check for soot and still carry a smell weeks later, since odor works into porous material, drywall, insulation, framing, at a depth surface cleaning can't reach. We treat odor as its own step, fogging enclosed cavities or running ozone treatment in sealed rooms, rather than assuming a good soot pass handles both at once.
| Stage | What Happens | Typical Duration |
|---|---|---|
| Emergency response | Board-up, tarping, soot and moisture assessment | Same day |
| Cleaning and drying | Soot removal, odor treatment, structural drying | 3 – 7 days |
| Rebuild | Drywall, paint, flooring, structural repair if needed | 1 – 6 weeks |
