Water standing against a slab keeps the ground the house bears on wet, so the work is getting roof water and runoff away from the house before anything else is priced.
Where is the water arriving from, and where is it going?
This group is the cheapest place on this site to spend money, and the first. If water stands against the house after rain, the ground at the slab edge is wet more often than it needs to be, and the work is to get surface water away: grade first, then extend the downspouts, in that order. Extending a downspout onto ground that slopes back toward the house just delivers the water further out and lets it run straight back. If water is getting in under a door or showing up on the slab, ask for a plumbing test before anything else, because a leaking line under the floor looks like a drainage problem from inside. If the floor has changed height, it is the leveling page, and these two are still worth doing first, because they are the cheapest work on any foundation and they decide where the water goes afterwards.
Where water goes when it lands on a Surprise lot
An ordinary two-year storm drops about 1.45 inches on Surprise in a day, onto lots around houses built, at the median, in 2004. Ground beside an older house has often settled back toward it over the years, and a downspout emptied at a corner sends a roof’s worth of that storm to one spot beside the slab. Grade and roof water are the cheapest things here to check and to fix.
What each foundation repair covers, and what it costs to get wrong
Surface Drainage Correction
Re-grading and shaping the ground within the first several feet of the structure so surface water leaves rather than stands. It is the first thing to correct, because water that stands against a slab edge keeps the ground the house bears on wet, and regrading is cheap next to anything done under the floor.
What moves the price. How much soil has to move and what is in the way. Beds, walkways, air conditioning pads and mature plantings all have to be worked around or lifted and reset.
When Surface Drainage Correction is the wrong answer. If the water is arriving from a neighboring lot or a street that drains toward you, regrading your own ground moves the problem a few feet. That is a larger conversation and sometimes a municipal one.
Gutter and Downspout Extension
Carrying roof water far enough from the structure that it does not soak the ground the foundation bears on, by extension or buried line. It is the cheapest intervention available on most lots and the one most often missing. A roof sheds a great deal of water into a very small area, right beside the slab.
What moves the price. Run length and whether the line is buried. Surface extensions are simple. A buried run needs a trench, a fall the whole way and somewhere legal to discharge.
When Gutter and Downspout Extension is the wrong answer. If the ground already slopes back toward the house, extending a downspout delivers the water further out and lets it run straight back. Grade first, then extend.

None of this can be priced from a description. Three things decide it. How many support points the house needs. How deep each one has to reach before it finds ground that does not move. How much of the work is indoors. All three are facts about an address, and none of them show up in a photograph. Send the address and what you are seeing. Someone who does this work in Surprise takes it from there. If it turns out to be a smaller job than the one you came here for, that is worth hearing before anyone starts.

The ground under Surprise
How much of this ground drains on its own decides where water at the slab edge comes from
44 percent of the land mapped here is soil that drains freely
Hydrologic groups A and B are the soils that take water down readily, and this is their share of the mapped land area. Where that share is small, rain stays near the surface and at the slab edge. Where it is large, water that still collects beside a house is usually arriving from somewhere specific. Either way, ask for grade and downspout discharge to be looked at first, because they are the cheapest work available.

The storm that soaks the ground beside a slab is a normal storm here
A ten-year storm drops 2.2 inches on Surprise in a day
The National Weather Service publishes this depth for this location with a stated confidence range. A storm that size is not unusual, and where the roof water from it lands is decided by the gutters and the grade. Ask what a proposal does with roof water specifically, and how many feet from the slab it ends up.

The soil group says whether water beside a slab moves down or stays
The largest soil mapped in Surprise is hydrologic group B
Hydrologic group ranks how readily a soil takes water down, from A, the fastest, to D, the slowest. On slow ground rain stays near the surface and at the slab edge; on fast ground water that collects beside a house is usually arriving from a downspout or a low spot. Ask what a proposal does with roof water, and how many feet from the slab it ends up.

Questions people actually ask
How far from the house should a downspout discharge?
Further than most are. The aim is to get roof water past the soil the foundation bears on, which means at least 6 feet from the wall, and 10 is better. A splash block at the wall does not achieve it.
How far should the ground slope away from the house?
Enough that water runs away rather than standing. A common rule is about 6 inches of fall over the first 10 feet, and soil that has settled against the wall over the years usually needs building back up to get there.
Does water at a door after rain mean the foundation has failed?
Not on its own. Water arriving at a threshold after rain is usually the grade or a downspout sending it there. It becomes a foundation question when the floor has changed height, and 2 sets of floor elevations taken months apart are how that is established.
Can a leak under the slab look like a drainage problem?
Yes, and it is worth ruling out early. A pressure test on the lines under the floor answers it in 1 visit, and it decides whether the fix is grading outside or a plumber inside.
What should I fix first?
Grade, then gutters, then everything else. Those 2 are the cheapest interventions available and they address the mechanism directly, which is why anything else bought before them is bought in the wrong order.
Ground that is saturated has nowhere to put the next storm, and water sitting against a wall keeps working on it.
What happens after you send an address
-
The address first, and only then who you are
The first screen asks for the property address and checks that a contractor covers it. Only if one does does it ask for a name, a phone number and an email — there is no point taking your details to tell you nobody serves your street.
-
Your details are not for sale
It goes to a foundation repair contractor working in Surprise. The details are never sold, and never passed to a second firm.
-
No cost, and nothing attached
There is no fee for sending an address and no obligation that follows from it. Deciding the work is the wrong work is a perfectly good outcome.
