How We Fix Your Drainage Issues

First, we evaluate your property’s current drainage patterns, soil conditions, and foundation layout. We identify where water collects, how it moves across your yard, and what’s causing it to flow toward your foundation instead of away from it.

Next comes the grading work itself. We reshape the land around your home to create the proper slope—typically 5% grade away from your foundation, which means six inches of drop for every ten feet. This ensures rainwater and snowmelt flow away from your house rather than pooling near your basement walls.

Finally, we install the right soil combination for your specific conditions. Clay-based soil for drainage areas that need to channel water efficiently, and quality topsoil for areas where you want grass and landscaping to thrive. The result is a grading system that protects your foundation while maintaining an attractive yard.

How do I know if my foundation needs grading work?

Standing water near your foundation after rain is the clearest sign you need grading work. You might also notice water stains in your basement, musty odors, or areas where your lawn stays soggy long after storms pass.

Many Hewlett homeowners don’t realize their drainage problems until they see water in their basement. By then, you’re dealing with emergency repairs instead of prevention. If water pools anywhere within ten feet of your foundation, or if the ground slopes toward your house instead of away from it, professional grading can prevent bigger problems.

Look for water marks on your foundation walls, erosion patterns in your yard, or areas where mulch and soil wash away repeatedly. These are all signs that water isn’t flowing where it should be.

Foundation grading reshapes the land around your home to direct water flow, while other drainage solutions like French drains or sump pumps manage water after it’s already collected. Grading is prevention; the other solutions are management.

Proper grading works by gravity—no mechanical parts to fail, no maintenance required beyond occasional inspection. When your yard is graded correctly, water naturally flows away from your foundation every time it rains. French drains and sump pumps are excellent additions to a grading system, but they shouldn’t be your only line of defense.

In Long Island’s climate, you want multiple layers of protection. Grading handles the bulk of surface water, while interior systems like sump pumps handle groundwater that seeps up through your foundation. The best approach combines both.

Most residential foundation grading projects in Hewlett take 2-3 days to complete, depending on your property size and the extent of drainage issues. Simple regrading around a typical suburban home usually finishes in two days, while properties with complex drainage problems or extensive landscaping might take longer.

The timeline includes site preparation, excavation and soil movement, proper soil placement, and final grading to ensure correct slope. Weather can affect the schedule—we won’t do grading work in heavy rain or when soil conditions are too wet to work properly.

You’ll see immediate improvement in water flow after completion, but it’s smart to observe how your new grading performs through a full season of storms. This helps identify any areas that might need minor adjustments, which we address under our warranty.

Professional grading minimizes damage to existing landscaping, but some disruption is unavoidable when reshaping land around your foundation. We protect valuable plants and trees whenever possible and work around established landscape features that don’t interfere with proper drainage.

Areas that need significant regrading will require new grass seed or sod after completion. This is actually an opportunity to establish a healthier lawn with proper soil preparation and drainage underneath. Most homeowners find their new lawn grows better than what they had before because the improved drainage prevents waterlogged roots.

Mature trees and established shrubs usually aren’t affected unless they’re planted too close to your foundation. We evaluate each landscape element during the planning phase and discuss any necessary changes before work begins. The goal is effective drainage with minimal disruption to your property’s appearance.

Long Island’s climate requires at least a 5% grade away from your foundation, which means six inches of drop for every ten feet of distance. This slope ensures rainwater flows away from your house instead of collecting near your basement walls.

The exact slope depends on your property’s conditions. Sandy soil near the coast drains quickly and might handle a gentler slope, while clay soil inland needs more aggressive grading to move water effectively. Areas with high water tables or frequent flooding might need steeper slopes combined with other drainage solutions.

You don’t want to exceed 5% grade in most areas because too steep a slope can cause erosion problems and create water pooling elsewhere in your yard. Professional grading finds the right balance between effective drainage and landscape stability, taking into account your soil type, lot size, and local drainage patterns.

Foundation grading eliminates many basement water problems by preventing surface water from reaching your foundation in the first place. If your basement flooding comes from poor yard drainage, standing water, or runoff from storms, proper grading often provides a permanent solution.

However, some basement water issues require additional solutions. Groundwater seepage, foundation cracks, or failed waterproofing systems need interior drainage work, crack repair, or waterproofing in addition to grading. A thorough evaluation determines whether grading alone will solve your problem or if you need a comprehensive approach.

The most effective strategy combines proper exterior grading with interior waterproofing systems when necessary. This gives you multiple layers of protection—grading handles surface water, while interior systems manage groundwater and any water that does reach your foundation. We evaluate your specific situation and recommend the right combination of solutions for permanent protection.
