What we do

Drainage

French drains, footing and curtain drains, catch basins and regrading. If water is standing where it should not be, the fix is almost always upstream of where you are seeing it.

Standing water is the problem people call about and almost never the problem they have. Water in a crawlspace, a yard that stays soft into June, a garage that wicks damp along one wall, moss taking over the north side of a driveway — those are symptoms of ground that is holding water and nowhere for it to go. Valley clay does not forgive a slope that runs the wrong way by an inch. We install French and curtain drains, footing drains around foundations, catch basins and area drains, and we run them to daylight or to a system that can actually take the volume, because a drain that ends nowhere is a hole that fills up. Often the real fix is not a pipe at all but regrading — moving a few inches of dirt so the ground does the work for free and permanently. When that is the answer we say so, even though it is the smaller job. Being the excavation contractor is what makes this work honest: we are not selling you a product, we are moving water, and the machine is here either way. Come out and walk it with us in the rain if you can. Nothing diagnoses drainage like actually seeing where it goes.

What is included

  • French drains, curtain drains, footing drains, catch basins and area drains
  • Run to daylight or to something that can take the volume — never to nowhere
  • Regrading when regrading is the real answer, even though it is the smaller job

Our process

How drainage jobs run

  1. Walk it, ideally wet

    We look at where the water arrives from, not just where it sits. If you can get us out during or just after real rain, an hour on site answers more than any amount of guessing.

  2. Say whether it is a pipe or a grade

    Sometimes the fix is a drain. Often it is moving dirt so the ground sheds water on its own. We say which, even when it is the cheaper one.

  3. Find the outfall first

    Where the water ends up gets settled before the trench is dug. A drain with nowhere to go is a reservoir with a pipe on it, and that is the single most common failure we get called out to.

  4. Trench, bed, backfill, restore

    Perforated pipe bedded in clean drain rock and wrapped, backfilled and compacted, and the surface put back so the yard does not look like it had surgery.

Questions

Questions about drainage work

  • Usually, yes — a wet crawlspace is normally a grading and footing-drain problem rather than a foundation problem, and it is worth finding out which before anyone sells you the expensive version. We will come out, look at the perimeter and the grade around the house and tell you plainly what we think is happening.
