About Littleton
Littleton is a city south of Denver that serves as the county seat of Arapahoe County, with a historic downtown and surrounding suburban neighborhoods.
Regional considerations
Parts of Colorado's Front Range are known for expansive clay soils and claystone bedrock that swell when wet and shrink as they dry. That movement can affect foundations, basement slabs, driveways and sidewalks, and it is one reason many local homes are built with deep foundations or floating basement slabs.
Front Range weather brings freeze-thaw cycles, spring snowmelt and summer storms. Keeping water away from the foundation with working gutters, extended downspouts, grading that slopes away from the house and careful irrigation near the foundation is a common first step before or alongside any repair.
Services Littleton visitors ask about
- Crawl Space Encapsulation: What crawl space encapsulation involves, when homeowners consider it, and questions to ask before hiring a contractor.
- Crawl Space Vapor Barriers: How crawl space vapor barriers work, how they differ from full encapsulation, and what to ask about materials and installation.
- Crawl Space Dehumidifiers: When a crawl space dehumidifier makes sense, how sizing and drainage work, and what to ask an installer.
- Crawl Space Insulation: Options for insulating a crawl space, the difference between floor and wall insulation, and what to ask a contractor.
- Sagging Floors: Common causes of sagging or bouncy floors over a crawl space and how support repairs are typically approached.
- Crawl Space Drainage: How water gets into crawl spaces, interior and exterior drainage options, and questions to ask before hiring.
Points to keep in mind
- Grading changes should not bury siding or block weep holes and vents. More on crawl space drainage.
- Combustion appliances in a crawl space, such as some furnaces and water heaters, need adequate combustion air. Sealing the space may affect them. More on crawl space encapsulation.
- In expansive soils, keeping water away from the foundation also helps limit soil movement. More on crawl space drainage.
- Floors in older homes are rarely perfectly level. Ask what is realistic for your house. More on sagging floors.
- Ask about the manufacturer warranty and who handles service. More on crawl space dehumidifiers.
- A dry crawl space in summer may still flood during spring snowmelt. Ask what conditions the system is designed for. More on crawl space drainage.
Getting ready to reach out
- Take photos of cracks, gaps, sloping floors or sunken slabs, with a tape measure or coin in frame for scale.
- Mention any previous foundation, drainage or concrete work, and whether a warranty came with it.
- Mention any doors or windows that stick, no longer latch or show new gaps.
- Note the age of the home and whether it has a basement, crawl space or slab.
- Note where gutters and downspouts discharge and whether irrigation runs near the house.
Good questions to ask any provider
- How does this affect my furnace, water heater or any radon concerns?
- What maintenance will the system need?
- Will you address any water entry before installing the liner?
- Do you see any moisture issues to fix before insulating?
- What maintenance will I need to do, and how often?
