A pier and beam house carries its weight on a grid of parts: concrete or masonry piers resting on footings, wood or steel shims on top of each pier, beams spanning between them, and joists running across the beams to hold the subfloor. When any one of those parts settles, crushes or rots, the floor above follows it. In Norman, the parts most likely to move are the shims and the interior piers, because Cleveland County clay keeps changing volume under them.
Our shop at 7220 S Western Ave in south Oklahoma City is about 25 minutes from Norman, which makes it easy to come down for a free inspection. We measure the floor with a level at several points, crawl to every reachable pier, and check whether each shim stack is tight against the beam. We also probe the beam ends and sill plate for soft wood, since rot and settlement often show up together.
Mark Bennett oversees every project, and the written quote spells out exactly which piers, beams or joists need work. If your home also has a moisture problem underneath, our Norman crawl space repair page covers that side. Here we focus on the structure itself: what holds the floor up, why it has drifted, and how to bring it back.
Why Norman Pier and Beam Floors Drift Out of Level
Most of central Oklahoma sits on clay that expands when it takes on water and contracts when it dries. A pier set into that clay rides up a little during a wet spring and drops back during a dry August. One cycle is barely noticeable, but forty or fifty of them leave some piers higher than others. The center of the house, where the piers are shielded from rain, often stays drier and drops more than the perimeter.
Shims are the second weak link. Many older Norman homes were leveled years ago with cedar or pine shims stacked on top of the piers. Wood shims compress under steady load and shrink as they dry, so a pier that was snug in 1985 may have a quarter inch gap today. Once a beam loses contact with a pier, the span doubles and the joists above start to sag between the remaining supports.
On the west side of town, soils closer to the Canadian River tend to be sandier and drain faster than the heavier clay farther east toward Lake Thunderbird. That difference affects how deep a new footing needs to go and whether we expect seasonal movement or one-time settlement.
Warning Signs in Norman Homes
- Interior doors in the middle of the house rub at the top corner or swing open on their own.
- A marble set on the kitchen or hallway floor rolls toward the center of the house.
- Diagonal drywall cracks run up from the corners of door frames and reopen after you patch them.
- The floor near the tub or washing machine feels soft or flexes when you step on it.
- Baseboards on interior walls show a gap above the floor that was not there when you moved in.
- Floor tile in a Norman bathroom or kitchen has cracked along a straight line that matches a beam below.
Repair Options We Use in Norman
Reshimming with steel shims
When the piers themselves are sound but the old wood shims have crushed or shrunk, we replace them with steel shims that will not compress. This is often the least expensive way to restore contact under older Norman homes.
Adjustable steel support posts
Where a pier has dropped too far to shim or the beam needs an extra support point, an adjustable steel post on a solid base fills the gap. The post can be fine-tuned later if Norman clay moves again.
Sistering floor joists
Joists that have sagged or cracked from years of overspan get a new full-length board fastened alongside them. We use this mostly near bathrooms and laundry areas where loads are heavy and wood has been damp.
Drainage correction around the foundation
Gutters that empty against the house soak the clay at the perimeter and make outer piers heave while center piers stay put. Extending downspouts and fixing the slope evens out how much water the soil gets.
Enclosed Porches and Room Additions on Older Norman Homes
Plenty of older houses around Norman have a back porch that was closed in or a bedroom added decades after the original build. Those additions were often framed on a separate set of piers, sometimes just concrete blocks set on the ground, with no footing at all. Over time the addition settles at a different rate than the main house, and you see it as a hump or dip in the floor right where the two meet, plus a crack in the wall above it.
Fixing that joint means treating the addition as its own small foundation. We check whether its piers have footings, whether its beam actually bears on the main house sill or just sits beside it, and whether the floor framing runs the same direction. Usually new piers on poured footings under the addition, plus shimming at the joint, bring the two sections back in line.
Pier and Beam Repair Cost in Norman
Pier and beam pricing in Norman depends on how many supports need attention. Reshimming and minor leveling runs $500 to $2,000. Adjustable steel posts cost $300 to $900 each, and new interior piers with footings run $400 to $1,200 each. Sistering a joist costs $300 to $900 per joist. A typical full leveling project lands between $2,500 and $10,000. After we inspect, you get a free written quote with every pier and joist listed.
