Steep lots, young houses

Foundation repair in Kennesaw on the mountain's slopes.

The median Kennesaw house was built in 1998, and only about one in ten predates 1980. So most foundation repair here is on homes 20 to 35 years old, built on steep ground. The most common soil near downtown is Madison and Pacolet on 10 to 25 percent slopes, mapped as eroded, with red clay subsoil running 40 to 50 percent clay. That clay rates low for movement. On slopes that steep, the repair story is about how lots were cut and filled for subdivisions and where runoff ends up.

Slopes up to 25 percent
Building a house on a 10 to 25 percent slope means a deep cut on the uphill side and fill on the downhill side. The downhill footings carry the most weight on the least settled ground.
Hard rock, old fault
Amphibolite, mica schist and biotite gneiss sit under the city, and the Noses Creek Fault crosses the battlefield park. Rock depth changes across a lot, so bearing under a house is not always even.
A small, older core
Kennesaw incorporated in 1887, but only about one home in ten here is older than 1980. Those older houses near downtown sit on shallower footings than the subdivisions that came later.

Cut and fill

Which footings sit on the dug-out side of the lot and which sit on placed fill.

Runoff path

Where water from the slope, the roof and the driveway collects next to the house.

Signs of movement

Slab and wall cracks, doors that bind, and gaps at trim and baseboards.

Common foundation problems in Kennesaw

Foundation symptoms common in Kennesaw homes.

Steep, eroded lots and a housing stock mostly from the 1990s and 2000s give Kennesaw a recognizable set of foundation symptoms. These four come up most.

Stair-step cracks on the low side

On a slope, the downhill footings often rest on fill. With about 54 inches of rain a year running down eroded clay toward them, they can settle and crack brick in steps.
Full diagnosis: stair-step cracks

A garage slab splitting

Three in ten Kennesaw homes were built in the 1990s. Garage slabs poured on fill from that era often show the first crack, then a widening gap as the fill keeps compressing.
Full diagnosis: cracked tile and slab

A corner sinking near the creek

Cartecay soils along the creek bottoms are frequently flooded, with water about a foot down. Butler Creek ran over flood stage in 2009, and footings on that wet ground can keep settling.
Full diagnosis: sloping floors

A basement wall cracking sideways

Basements dug into 10 to 25 percent slopes hold back a tall face of clay. A horizontal crack in that wall means the soil load is winning, and it can turn into a bow.

Spot one of these? It is worth a measured look before it grows.

The FoundationRX Diagnostic Method

How we diagnose foundation problems in Kennesaw.

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 Kennesaw homes.

A settling fill-side footing and a basement wall pushed in by a tall clay slope are different jobs. These are the three methods on our menu, and your Kennesaw diagnosis decides which one fits.

Pier Stabilization

Steel push piers are driven beside the settling footing, through fill and wet clay, until they meet load-bearing soil or rock. The house rests on the piers from then on, and the dropped side can often be raised back toward level.

Best for: fill-side settling, dropped corners, step cracks.

Wall Stabilization

A basement wall bowing under a steep slope gets braces or anchors that stop it moving, and it can be eased back over time. Bracing is our more common choice; anchors suit some walls better.

Best for: basement walls with a bow or lean.

Carbon-Fiber Reinforcement

When a Kennesaw basement wall has only a horizontal crack and no real bow yet, carbon-fiber straps bonded to it hold it there. The straps take almost no room in a finished space.

Best for: horizontal cracks before the wall bows.

Other services in Kennesaw

Problems that often come along with it.

A Kennesaw foundation problem on a hillside lot often has basement water beside it, and creek-side homes deal with damp crawl spaces. The same team can handle either.

Basement Waterproofing

The same slope that pushes on a basement wall sends water through its cracks. Draining it keeps the wall repair working.

Crawl Space Encapsulation

Crawl spaces over the wet Cartecay creek bottoms stay humid. Sealing them protects the framing over a repaired foundation.

Sagging Floor Repair

A bouncy or dipping floor may be the joists, not the footing. In that case the repair is smaller.

Floor Rebuilds

When damp has ruined the sub-floor and joists, the whole floor system is rebuilt from the framing 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

Kennesaw foundation repair FAQ.

Yes, hard crystalline rock: amphibolite, mica schist and biotite gneiss under the city, the same family of rock that makes up the mountain. No limestone is mapped, so sinkholes are not the concern. Rock depth does vary from lot to lot, and the depth to firm bearing is measured during the repair, not guessed.
