French drains for Allen yards that stay wet
Allen's mature neighborhoods off Bethany, Exchange, and McDermott have a lot of shade — which is great for the house and hard on drainage. We help Allen homeowners handle French drains under Bermuda that won't grow, downspout runs from tall two-story homes, and re-grading around older concrete patios that trap water against the slab.
A French drain is the right conversation when the ground itself is saturated, not just when a puddle appears on top. In Allen, that often means side yards between homes, back-fence low spots, shaded grass, new patios that changed the slope, and downspouts that keep soaking the same strip of clay.
Allen's older neighborhoods off Bethany and Exchange sit under a heavy tree canopy on settled clay. Shade plus clay is the classic Allen drainage combo — the yard just never fully dries between rains.
The goal is to move water away from the wet area and keep repeated saturation from pushing moisture toward the slab, flower beds, or low side yards.
Signs your Allen yard may need a French drain
- Soggy grass that stays wet days after rain
- Standing water along the fence line or side yard
- Mud, mosquitoes, or dead turf in the same low spot
- Water sitting near the foundation or flower beds
- Runoff from a neighbor's slope, patio, or pool deck
- Downspouts dumping into already saturated soil

French drain cost factors in Allen
French drain pricing depends on trench length, depth, soil conditions, outlet location, gravel volume, fabric, pipe type, sod replacement, and whether the system also needs catch basins or buried downspout extensions. Most mistakes happen when a drain is too shallow, too flat, or discharges to another low spot.
Take photos after rain, estimate the wet area's length and width, note nearby downspouts, and look for the nearest lower discharge point such as the street, alley, or drainage easement.

French drain FAQ - Allen, TX
Do French drains work in North Texas clay soil?+
Yes, but the design matters. In Collin County clay, a French drain needs enough depth, slope, gravel, and fabric so it can collect subsurface water instead of becoming a shallow muddy trench.
How much does French drain installation cost?+
Most residential French drain projects depend on trench length, depth, outlet, access, and whether catch basins or downspout lines are included. A single problem area may be a few thousand dollars; larger perimeter or multi-run systems cost more.
Do I need a French drain or a surface drain?+
A French drain is usually best for soggy, saturated soil. A surface drain or catch basin is better for visible puddles. Many Collin County yards need both working together.
Where does the French drain water go?+
Water needs to discharge to a lower, approved location such as the street, alley, drainage easement, pop-up emitter, or another safe outlet. The outlet is as important as the trench.
