Service
Drainage
French drains, downspout routing, and yard drainage solutions that protect your foundation.

Standing water and soggy yards lead to foundation damage and costly repairs. We design and install drainage systems that move water away from your home — French drains, channel drains, downspout extensions, and full grading.
Every drainage project at KMBJ starts with a free in-person consultation. We listen first, then put together a detailed scope and a transparent estimate so you know exactly what you're getting and what it costs — no surprises.
Once work begins, you'll have a single point of contact, daily progress updates, and a clean, organized job site. We don't consider a project complete until you've done a final walk-through and signed off.
