Avoid Water Damage, Erosion, and Drainage Headaches

Poor drainage doesn’t just make a yard messy — it can cause erosion, pooling water near foundations, and hardscapes that settle or shift over time. We fix the problem at the source with proper grading, drainage planning, and clean site prep so water moves where it should and your property stays protected.

Frequently Asked Questions About Drainage & Site Prep

At Fraser Valley Contracting, we understand that drainage and grading work comes with important decisions. Below are answers to common questions homeowners ask about pooling water, erosion, timelines, and what to expect during drainage and site prep work.

The best solution depends on your slope, soil conditions, and where water is coming from. In many cases, we combine regrading with targeted drainage (like intercepting runoff before it cuts through the yard) to slow water down and guide it safely away from problem areas.

Common signs include standing water after rainfall, soggy lawn areas that never dry out, washouts or channels forming during storms, water pooling near patios or foundations, and hardscapes that start to settle or shift over time.

Timelines vary depending on access and how complex the issue is. Many drainage fixes and regrading projects take a few days, while larger slope or erosion-control projects may take longer. After a site visit, we’ll give you a clear timeline and scope.

Yes. Proper grading and drainage are a major part of long-lasting hardscaping. We plan water flow during site prep so patios stay level, retaining walls stay stable, and runoff doesn’t create ongoing problems later.
