Downspout and Grading

Have ready

Clear the ground along the foundation so the wall and the soil line are visible, and move anything stored against the house. If you can, watch where water goes during a heavy rain and note it for us. The first three checks are the slope of the soil within the first few feet of the wall, the downspout size and how many feet of run it needs, and where the water currently ends up, since a splash block at the corner just returns it to the same spot.

• Extend the downspouts
• Regrade away from the wall
• Catch basins
• Low-spot check

The visit

A downspout and grading visit starts by naming the failure, not by selling the fix. We check what the problem touched, protect the floors and the rooms below, and leave a written scope. The work is done in one sequence by the same company, so the trade that caused the damage is the trade that closes it.

What fails first on the Shore is what we look at: salt-rotted fasteners, water finding the soft spot, and the 'quick fix' that never dealt with the cause. For downspout and grading, the tell is usually visible on the first visit, and we say what it means in plain English.

Permit

Extending downspouts and regrading your own yard normally does not require a permit in New Jersey. A permit question comes into play when the grade change is significant, when water is directed toward a property line or a neighbor, or when a catch basin connects to a municipal system. A buried line in a right-of-way may also need approval. We check the town rules before the work starts.

On the Shore

Flat Shore lots and sandy soil mean water soaks in slowly and sits against the foundation. Freeze-thaw then works on both the soil and the wall: saturated ground expands, pushes the grade, and can crack a slab or step. Salt spray kills the grass at the drip line, so bare soil there erodes and puddles form. Downspout extensions and a positive slope away from the wall matter more here than a bigger gutter.

When we leave

We run water through each downspout and confirm it exits well away from the wall without pooling at the outlet. The regraded soil is firmed and checked for a consistent fall away from the foundation, and low spots are filled rather than hidden. Care note: keep the extensions in place through winter, since ice at the outlet will back water up the spout, and recheck the grade after the first freeze-thaw season.

Built with

Downspout extensions are corrugated or rigid plastic, and buried runs use solid pipe with a pop-up emitter or a splash block at the end. Catch basins are plastic with a grate, set in washed stone. Regrading uses screened topsoil or a compactable fill, finished with seed or sod. Plastic is chosen over metal for the buried parts because salt air does not rot it.
