New houses, graded ground

Foundation repair in Alpharetta for houses built since 2000.

Alpharetta built more than 9,000 homes between 2000 and today, and fewer than one in twelve is older than 1980. Nearly half the ground near the center is mapped as urban land, meaning graded and built over. Under that, Appling soils carry strong brown clay from about one foot to four feet deep, and the main soils rate low for movement at 1.5 to 2.2 percent. So a cracked Alpharetta foundation is rarely the clay acting up. It is usually fill that has settled, or water from a graded lot that keeps landing in the same spot.

Clay three feet thick
Appling subsoil is strong brown clay from about 12 to 48 inches down. Footings rest in that layer, and clay soil that thick holds water against them when a lot drains poorly.
Steeper and stony lots
Rion sandy loam on 10 to 15 percent slopes and stony Grover-Mountain Park soils, with soft rock about 32 inches down, cover parts of town. Footings cut into those slopes can bear unevenly.
Tributaries, not just Big Creek
FEMA has flood studies for several numbered Big Creek tributaries and Camp Creek. Near them, Wehadkee soil is poorly drained, with water as shallow as five inches for part of the year.

Fill and grading

Where the lot was built up, how it drains, and whether water pools near the footing.

Basement walls

Horizontal and stair-step cracks, bowing, and gaps where walls meet the slab.

Outside the house

Stoops, porches and garage slabs pulling away or dropping.

Common foundation problems in Alpharetta

Foundation warning signs in Alpharetta homes.

Young houses on graded lots, wet tributary bottoms and some steep stony ground give Alpharetta a set of repeat foundation signs. These four come up most.

Brick cracking by the garage

Garages and front stoops often sit on the deepest fill on a graded lot. In houses from the 2000s, brick beside the garage is a common first place to see stair-step cracks.
Full diagnosis: stair-step cracks

A basement wall leaning in

Hard Labor soil holds a wet layer about 32 inches down, and the area gets around 56 inches of rain a year. Soil that wet against a basement wall can push it inward.
Full diagnosis: bowing walls

Doors sticking on one side

On stony slopes where soft rock sits near 32 inches, one side of a house can bear on rock while the other settles. Doors on the settling side drift out of square.
Full diagnosis: sticking doors

Floors tipping toward the creek

Homes backing onto the mapped Big Creek tributaries sit beside soils that stay wet near the surface. The low side of the footing can settle, and the floor slopes that way.
Full diagnosis: sloping floors

The FoundationRX Diagnostic Method

How we diagnose foundation problems in Alpharetta.

A lot of foundation repair companies show up to sell you the most expensive thing they install. We show up to figure out what's actually wrong under your home first, then prescribe the repair that fixes it, and tell you straight, even when the answer is "you don't need as much as you were told." That's the difference between a sales call and a diagnosis.

01

Diagnose

A free in-home inspection by someone who does this work, not a commission salesperson. We look at the real signs, inside and underneath, and walk you through what's actually causing the movement. You get a clear, honest read on where your home stands.

02

Prescribe

We lay out the right fix for what's actually wrong, not the priciest line item. A plain-English explanation and a fair price in writing. We go over the plan and your options, and you decide on your own time. No "today only" pressure.

03

Treat

Dependable work by our own local crew, on time, cleaned up after themselves, and finished on or ahead of schedule, the way our customers describe it. We keep you in the loop from the first day to the final walkthrough.

Most foundation companies sell you a fix. We diagnose first, then prescribe only what your home actually needs. That's the difference between an honest local team and a sales quota from out of town.

How we fix foundations

Foundation repair methods for Alpharetta homes.

Settled fill under a garage and a basement wall pushed in by wet clay are two separate repairs. These are the three methods on our menu, and your Alpharetta diagnosis decides which one fits.

Pier Stabilization

Steel push piers are driven beside the settling footing, through fill and clay, to load-bearing soil or rock below. With the footing on the piers, settling stops, and a dropped garage corner or stoop can often be raised back toward level.

Best for: settled fill, garage corners, step cracks.

Wall Stabilization

A basement wall leaning under wet clay gets braces or anchors that hold it so it stops moving, and it can be eased back over time. Bracing is our more common choice, with anchors where the wall suits them.

Best for: basement walls that lean or bow.

Carbon-Fiber Reinforcement

Carbon-fiber straps bonded to a basement wall with its first horizontal crack hold it in place. They are thin enough for finished Alpharetta basements, where bulky hardware would cost living space.

Best for: early cracks in finished basements.

Other services in Alpharetta

Problems that show up alongside foundation movement.

In Alpharetta, a moving basement wall often lets water in too, and low lots near the creeks can have damp crawl spaces. The same team covers both if the inspection finds them.

Basement Waterproofing

A leaning wall usually seeps through the same cracks. Draining the water helps the wall repair hold for good.

Crawl Space Encapsulation

Crawl spaces beside the wet tributary soils draw in damp air. Sealing them keeps the framing dry.

Sagging Floor Repair

A dip in the floor is not always the foundation. Sometimes it is joists or posts, and that fix is smaller.

Floor Rebuilds

Floors soaked by basement or crawl space flooding can need a new floor system, built from the joists up.

What homeowners say

In their own words.

Misty Little
“This company came out to my home and did a great job. They took my very nasty crawl space that was full of water and transformed it into a dry healthy place. My encapsulation of my crawl space looks exactly like the pictures they posted. My only regret is not doing this sooner! From the office to the crews, it was a smooth, enjoyable experience.”
K. Schantzer
“From start to finish the process was great. FoundationRX repaired my foundation and installed an encapsulation system with drainage in my crawl space. My home no longer smells from the moisture! Would highly recommend FoundationRX for all your home foundation, water intrusion issues. Reasonable prices as well!”
Bobby Stinson
“Had Ryan come do an estimate and I had severe water damage. The estimate was great so I hired them, these guys are professionals, they got rid of all the damage replaced all the damage seals floor joists and refloored, and it looks great also had them do water control and these guys don't mess around, they did a professional job and took care in doing it!”

Frequently asked

Alpharetta foundation repair FAQ.

It can. More than 4,000 Alpharetta homes went up in 2010 or later, most on graded lots. If fill under part of the house was not compacted well, it can settle in the first decade. Not every crack in a new home is a problem, but a crack that grows, or brick that steps apart, is worth having measured.
