Colorado Soil & Weather Guide
Colorado's 2026 Drought Is Cracking Foundations. Here's What's Happening Under Your Home
All of Colorado is in drought for the first time since 2021 — and foundation repair calls across the Front Range are surging. The connection isn't a coincidence. It's expansive clay doing exactly what expansive clay does.
In spring 2026, Colorado entered statewide drought for the first time in five years, following a record-low winter snowpack. By March, the state had activated its formal drought response plan. If you own a home anywhere along the Front Range, that weather headline is also a structural one — because drought is the single biggest driver of foundation damage in Colorado.
Why Drought Breaks Foundations
Much of the Pikes Peak region and Front Range sits on expansive clay soil — soil that swells when wet and shrinks when dry. The Colorado Geological Survey estimates expansive soils cause more property damage in Colorado each year than floods, tornadoes, and earthquakes combined.
In a drought year, the clay around and under your foundation dries out and contracts. Three things follow:
- The soil pulls away from foundation walls, removing the lateral support the foundation was built against.
- Support becomes uneven. Soil in shade or near irrigation stays moist while exposed soil shrinks, so parts of the home settle while others don't — that differential movement is what cracks foundations.
- Deep cracks open in the ground, becoming direct channels for water when the rain finally returns.
The Monsoon Double-Punch
Forecasters expect an active July–September monsoon over Colorado this year. That's the second half of the damage cycle: heavy storm water races down drought-opened cracks, the starved clay re-swells fast and unevenly, and hydrostatic pressure loads up against basement walls that just spent months losing their support.
Shrink hard, then swell hard — a single drought-plus-monsoon year can move a foundation more than five normal years. It's why foundation repair companies across Colorado are having their busiest season in memory, and why the damage you notice in August usually started in March.
Warning Signs to Check This Season
- New or widening cracks in drywall, especially stair-step patterns above doors and windows
- Doors and windows that suddenly stick or won't latch
- Gaps opening between floors and baseboards, or counters pulling away from walls
- Visible gaps between the soil and your foundation outside
- Cracks in exterior brick or the foundation wall itself — vertical, diagonal, or horizontal
- Water in the basement after storms that never leaked before
Don't water your foundation blindly. A common DIY tip is soaking the soil around the house during drought. Done unevenly, it makes differential movement worse. Consistent, moderate moisture on all sides helps; a soaker hose on one problem corner doesn't.
What to Do Before Storm Season Peaks
If you've spotted any of the warning signs, get the foundation inspected before the re-swell cycle finishes the job the drought started. A free inspection tells you whether movement is active, whether it's structural or cosmetic, and what it costs to stop — see our Colorado Springs cost guide for real numbers. Settlement gets stopped permanently with helical piers that reach below the active clay layer, and drought-opened water paths get handled with basement waterproofing before they flood anything.
Foundation damage from expansive soil never reverses on its own — but caught early in a drought year, it's at its cheapest to fix.
