Local conditions in Downtown Littleton

Downtown Littleton centers on Historic Main Street, a compact grid of older streets near the South Platte River. Water from storms and snowmelt can collect in low spots, alleys and the lowest levels of older buildings.

Littleton sits at roughly 5,300 feet on the Front Range, where the climate is semi-arid. The Denver metro area averages only about 15 inches of precipitation a year, so outdoor air is usually dry. That dryness surprises many homeowners who find mold: it is rarely the weather outside that feeds it. It is water that gets into the building and stays there.

Homes in Downtown Littleton and where moisture hides

Housing near downtown includes late 1800s and early 1900s cottages, brick and stone homes, mid-century infill and newer townhomes. Older houses often have stone, brick or rubble foundations, cellar-style basements with low ceilings, plaster-and-lath walls and original plumbing that has been repaired many times.

Mold problems we see in Downtown Littleton

Damp stone and brick foundations

Masonry wicks groundwater and spring snowmelt, and old foundations rarely have modern waterproofing. Cellar walls stay damp, and stored items, wood framing and finishes pick up mold over time.

Slow leaks behind plaster walls

Original galvanized and cast-iron lines fail slowly. Water travels through lath and plaster, so staining and smell may appear far from the actual leak.

Layered roofs and old flashing

Multiple roof layers, patched chimneys and aging flashing let small amounts of water into attics and upper walls, especially after wet snow.

Humidity in older, drafty homes

Winter humidifiers in older homes can cause window and exterior-wall condensation, which leads to mold on sills, plaster and wood trim.

What causes mold in Downtown Littleton homes?

These are the moisture sources we look at first in this part of town:

Aging supply and drain lines inside plaster or lath walls
Damp stone or brick foundations and cellar-style basements
Old roof sections with layered repairs and tired flashing

Signs of mold in Downtown Littleton

A cellar smell that gets worse after storms or snowmelt
Peeling or bubbling plaster and paint on exterior walls
White mineral crust on stone or brick basement walls
Dark staining near chimneys, old window frames and porch roofs

Seasonal mold risk near Downtown Littleton

Winter

Ice dams, frozen and burst pipes, window condensation from humidifiers, and moisture trapped behind closed-up attics.

Spring

The highest-risk season. Wet snow, rapid melt and storms drive water into basements and crawl spaces and expose slow roof leaks.

Summer

Afternoon thunderstorms and hail, evaporative (swamp) cooler humidity, and air conditioner condensation lines that clog or overflow.

Fall

Clogged gutters from leaves, sprinkler blowout problems and the first cold nights that bring condensation in poorly ventilated rooms.

How to prevent mold in Downtown Littleton

These steps fit the conditions in this part of town:

Keep gutters and downspouts clear and extend downspouts at least several feet from the foundation, especially under mature trees.
Check basement walls and window wells each spring after snowmelt for dampness, efflorescence and standing water.
Look at older plumbing under sinks, around water heaters and in utility closets twice a year, and replace aging supply hoses.
Duct bathroom fans outdoors, not into the attic, and run them during and after showers.
Keep indoor relative humidity between 30 and 50 percent, and use a hygrometer to check it.
In older homes, add vapor control and ventilation to crawl spaces and have a roofer check flashing before winter.

What to do if you find mold in Downtown Littleton

Stop the water source if you can, keep the area dry and avoid disturbing the mold. Do not run fans that blow across the growth. Take photos, then call us for a visit.

A Downtown Littleton job follows the same sequence as every other: we find the mold and the moisture source, set containment and negative air, remove affected materials, clean, dry and document.
