Stucco waterproofing in Yonkers has to start further back than the wall. A house on a slope sits at the bottom of everything above it, so water arriving at your masonry has already crossed ground that belongs to somebody else.
A house on flat ground deals with the rain that falls on it. A Yonkers house on a hillside deals with that plus everything shed by the land above it. Roofs, driveways, lawns and road surfaces uphill all send water downhill, and it keeps moving until something stops it. On most sloped Yonkers lots the first solid object in its path is the back of the house.
As a stucco waterproofing contractor in Yonkers we walk the ground above the wall before examining the wall itself. Water arrives two ways here. Surface flow runs across the ground and is visible during heavy rain. Subsurface flow travels through the soil and shows up nowhere at all until it reaches masonry, which is why the second one causes most of the confusion.
Four things that only apply to a property sitting on a slope.
Everything uphill of a Yonkers house sheds water downhill, and your building is what stops it. That is a volume decided by the land above you rather than by the size of your own roof.
Surface flow is visible during a storm and easy to trace. Subsurface flow moves through the soil itself, gives no warning, and is what most owners are actually dealing with when damp appears with no obvious cause.
What crosses a Yonkers boundary depends on paving, planting and drainage uphill on land you do not own. You cannot reduce it at source, so the only lever you have is where it goes once it reaches your ground.
Intercepting water before it reaches masonry is site work. It is a different job from anything applied to a Yonkers wall, and on a hillside property it is usually the one that actually solves the problem.
Uphill of the affected elevation, as far as the boundary and beyond it where we can see. Slope, paving, planting, where a neighbor's downspout discharges and whether anything already diverts water. That walk explains most Yonkers damp reports before anybody looks at masonry.
Water on a slope does not arrive evenly. It follows the low line, and on a Yonkers lot that line usually meets the house at one point. Staining, erosion and where the ground stays soft after rain all mark it.
Where the volume can be caught and redirected on your own Yonkers lot, that is the repair, and we carry it out ourselves. We say plainly when a job is site work rather than masonry work, because it prices and schedules differently.
A coating changes how a wall handles what reaches it. It does nothing about how much reaches it. On a Yonkers hillside the volume arriving at the back of a house is set by the land above, not by the weather alone, and it keeps arriving at the same rate whatever is applied to the masonry. That is why these walls get treated repeatedly and stay damp. Ask anyone quoting a coating what they found when they walked uphill of the wall. If nobody walked uphill, nobody has looked at the actual source.
The grade runs through the whole city, so the same uphill question applies from Ludlow and Nodine Hill through Dunwoodie to Crestwood and Beech Hill.

On a Yonkers slope, regularly. Rain falling uphill of you moves downhill across and through the ground until something stops it, and your wall is frequently the first thing in its path. The volume is decided by land above your boundary rather than by your own roof.
Surface flow runs visibly across the ground during heavy rain and is straightforward to trace. Subsurface flow moves through the soil itself with nothing showing above it, then appears at masonry. On a Yonkers hillside the second one accounts for most damp that seems to have no cause.
Only partially, and it is rarely the best use of money. A wall with earth against it is receiving water continuously rather than during storms. Reducing what reaches it works better than improving what it resists, which is why the ground uphill matters more than the coating.
Interception on your own land. Redirecting surface flow, cutting off the low line where water concentrates, and giving subsurface water somewhere to go before it arrives. On a Yonkers lot we do that work ourselves, priced as site work rather than as masonry.
Because the ground releases what it held through winter. Frozen soil stops water moving, so it accumulates, and when it thaws that volume arrives at once. On a sloped Yonkers property the spring thaw frequently produces the worst damp of the year with no unusual rainfall behind it.
