Concrete Contractors in Wilmington Manor, DE

Wilmington Manor sits just northwest of New Castle and south of Wilmington, and concrete contractors working here mostly deal with established homes. The 1970 census counted 10,134 residents; by 2020 the count was 8,162, in 3,175 housing units. A population that peaked decades ago points to a neighborhood that was largely built out by then. In practical terms, much of the concrete here has been in place for a long time, and many homeowners are now at the replace-or-repair stage.

Reading an older driveway

An older driveway tells you what it needs if you know where to look:

At the garage. A gap or drop where the driveway meets the garage floor often means backfill settled next to the foundation.

At the street. Broken edges near the curb come from tires turning on a thin apron.

In the middle. Long cracks across the slab show where joints should have been. If the two sides are level, sealing may do. If they have shifted, the base has failed.

On the surface. Flaking and pitting usually mean the concrete was not air-entrained or has taken a lot of salt.

We look at all four during an estimate and tell you which fixes are worth doing.

Flat, low ground

Wilmington Manor sits at about 59 feet, on flat land. Flat ground drains slowly, so a slab poured level will hold water and let it soak into the base. We give every new slab a set fall away from the house and toward a lawn edge or the street. We also look at downspouts, which often empty right onto a walk or driveway.

Replacing walks and stoops

Front walks and stoops take a beating from foot traffic, salt and freeze-thaw cycles. In an older neighborhood, many are cracked, tipped or flaking. We remove the damaged sections, rebuild the base and pour new concrete at a level that meets the door threshold properly. A light broom finish adds grip without being rough on bare feet.

New patios and slabs

Not every job is a fix. Owners often want a back patio, a shed slab or a wider driveway. A plain broom-finished patio is durable and easy to keep up. Stamped concrete adds color and pattern for those who want more. For a shed, we pour a level slab with thickened edges where the walls sit.

The regional weather record

Wilmington's climate normals are recorded at New Castle County Airport. Those normals show a January average of 32.4 degrees, about 20.2 inches of snow and 45.33 inches of precipitation a year. That much water and that many freeze-thaw cycles explain a lot of the damage we see on older concrete. Our exterior concrete is air-entrained and properly cured, and we recommend sealing it after it cures.

Lifting versus replacing

When a section of driveway or walk has sunk but is otherwise in one piece, lifting it back to grade can be an option. It costs less than replacement and leaves the old surface in place. If the slab is cracked through, scaled badly or has sunk more than once, replacement is the better choice. We tell you which applies after looking at the slab and the ground around it.

Between the city and the river towns

At about 59 feet, Wilmington Manor sits lower than Wilmington's official 92 feet but well above New Castle's 10 feet to the southeast. That middle position means water does drain, but slowly, and the margin for error is small. A slab that is even slightly back-pitched toward the house will hold a thin sheet of water, and in winter that sheet freezes. We set grades with a string line rather than by eye, and we check the yard beyond the slab so water leaving the concrete has somewhere to go.
