Crawl Space Encapsulation Boulder, CO
Eliminate moisture, mold, pests & radon - sealed, insulated, and protected by Boulder's crawl space encapsulation experts.
Trust me, if you've been putting off dealing with that crawl space, you're not alone. Most Boulder homeowners avoid crawl space encapsulation until something forces their hand - usually a musty smell that won't go away or an energy bill that makes them wince. Your crawl space affects your entire home's foundation health, and Boulder's unique climate makes crawlspace encapsulation even more important for preventing moisture damage and mold growth.

Why Boulder Crawl Space Areas Need Professional Attention
Boulder's climate + local soils = crawl space trouble
Here's what we see constantly in Boulder homes: our clay-heavy soil holds moisture like a sponge, and when you combine that with our wild temperature swings? Your crawl space becomes a breeding ground for problems that require professional repair services
According to the EPA, about 1 in 15 homes nationwide has elevated radon levels. But in Boulder County? We're dealing with significantly higher rates due to our geological makeup, making crawl space encapsulation and radon mitigation absolutely crucial for every basement and crawlspace area.
The triggers we see most in Colorado homes:
Moisture pooling after spring snowmelt that damages your foundation
Humidity spikes during summer storms affecting your crawl space
Radon seepage through foundation cracks requiring immediate repair
Temperature fluctuations that create condensation and water damage
Had a client last month in the Table Mesa area - she thought her "old house smell" was just character. Turned out her crawl space was basically a swamp, requiring extensive mold remediation and foundation repair work. The moisture damage had spread throughout the space, affecting the entire basement systems and requiring comprehensive crawl space repair solutions.
Our Crawl Space Encapsulation Services
We don't do cookie-cutter fixes. Every Boulder home has its own personality (and problems), which is why our encapsulation services are completely customized.
Vapor Barrier & Insulation CleanSpace® 20-mil barrier system - think of it as a raincoat for your crawl space. Way more durable than that flimsy plastic you see in most places. This vapor barrier protection prevents moisture from seeping into your space and causing foundation damage.
Full Encapsulation Wall-to-floor sealing that actually works. We handle radon mitigation and pest blocking because nobody wants uninvited guests down there. Our comprehensive encapsulation approach addresses every aspect of your crawl space repair needs.
Drainage & Sump Systems Foundation drains paired with sump pumps. When Boulder's notorious spring runoff hits, you'll be ready. Our water management solutions prevent basement flooding and protect your foundation from costly repair work.
Climate Control & Vent Covers Humidity regulation that can cut your energy costs by 15-20% (we've tracked this with clients over the years). These systems work together to maintain proper moisture levels throughout your crawl space and basement.
One thing we learned the hard way - sealing without proper drainage is like putting a band-aid on a broken pipe. We do both, ensuring your space stays dry and your foundation remains structurally sound for years to come.

Is Crawl Space Encapsulation Right for Your Home?
Boulder's climate + local soils = crawl space trouble
Even one of these should get your attention and prompt immediate action:
Condensation on pipes or ductwork in your crawl space
Musty odors that follow you upstairs from the basement area
Floors that feel uneven or bouncy, indicating foundation issues
Pests making themselves at home in your crawlspace
Energy bills climbing for no clear reason, often due to poor space insulation
Water pooling or moisture damage in your crawl space
Mold growth anywhere in your basement or crawlspace
We had a family near Chautauqua Park who ignored the musty smell for two years. By the time they called us, they were dealing with actual mold remediation and extensive foundation repair - way more expensive than prevention would've been. The damage had spread throughout their crawl space, affecting the entire basement and requiring comprehensive repair solutions.
Real Benefits You'll See
What Boulder homeowners experience
This isn't marketing fluff - these are results we track with our clients after completing crawl space encapsulation work.
Air Quality & Health Radon levels typically drop 60-80% with proper mitigation. Humidity stays controlled year-round throughout your crawl space and basement. One client's daughter stopped having mysterious respiratory issues within a month of our encapsulation work - the mold spores were finally eliminated from their space.
Energy Efficiency Average savings of $200-400 annually on heating and cooling costs. Your HVAC system won't work as hard when it's not fighting moisture and temperature swings from an unsealed crawl space. Proper encapsulation creates a barrier that keeps your foundation temperature stable.
Home Value & Structure Prevents wood rot, foundation settling, and pest damage throughout your crawl space and basement areas. Plus, professional encapsulation is a major selling point when you eventually move. Buyers appreciate knowing the foundation and crawlspace have been properly maintained with quality repair work.
​According to Remodeling Magazine's 2024 Cost vs. Value report, moisture control improvements typically return 70-80% of investment at resale, making crawl space encapsulation one of the smartest home improvement investments you can make.
