Pier and Beam Foundation Repair: DIY vs. Hiring a Pro
Some pier-and-beam fixes are safe weekend jobs. Others can drop a house on you. Here is the line between DIY and calling a pro, with Shreveport costs and safety rules.
Is it easy to fix a pier and beam foundation? Some of it is — adding shims under a low spot or sistering a rotted joist is honest weekend work. But lifting a house, replacing piers, or reworking beams is not a DIY job. Get that wrong and the house can shift or drop.
Shreveport has more pier-and-beam homes than most Louisiana cities — whole neighborhoods in Broadmoor, Shreve City, and toward Blanchard sit on crawl spaces, many fifty-plus years old. This guide draws the line between what you can handle and what needs a crew, because guessing wrong under a house costs more than money.
Is It Easy to Fix a Pier and Beam Foundation? The Straight Answer
It depends entirely on which fix you mean. A pier-and-beam foundation is a system — piers, beams, joists, subfloor — and some parts are homeowner-friendly while others carry genuine danger. Sistering a joist to firm up a bouncy floor is carpentry. Re-leveling the house is structural work where a mistake can rack the frame, break plumbing, or drop a section of the home.
The honest rule of thumb: if the repair changes the height of the house or the load path through the structure, it belongs to a professional. If it reinforces wood that is already in place without lifting anything, a careful homeowner can often handle it. Everything below spells out exactly where that line falls, so you are not learning it by trial and error under your own floor.
Getting a free inspection does not obligate you to hire anyone. Elevation readings show how far out of level the house is — useful whether you DIY or hire. Know the numbers before you pick up a tool.
Repairs You Can Safely Do Yourself
Plenty of pier-and-beam maintenance is well within a handy homeowner’s reach. These jobs do not lift the house or redirect structural loads, which is what keeps them safe:
- Sistering floor joists: bolting a new joist alongside a sagging or cracked one stiffens a bouncy floor without changing any heights. Straightforward carpentry with a drill, bolts, and construction adhesive.
- Adding shims at settled spots: thin steel or hardwood shims slipped between a beam and pier can take the bounce out of a mildly low area. Small adjustments only — a quarter inch here, not two inches.
- Replacing rotted rim joist sections: short decayed runs can be cut out and replaced piecemeal while surrounding structure carries the load.
- Crawl space cleanup and moisture control: laying a vapor barrier, clearing debris, and improving vent airflow are pure maintenance with real payoff in Shreveport’s humid climate.
- Minor pier repointing: touching up deteriorated mortar on concrete block piers keeps them weathering well.
Budget $150 to $500 in materials for most of these jobs. The work is physical and the crawl space is unpleasant, but none of it risks the structure. See our pier and beam foundation repair services for the full picture.
Jobs That Belong to a Professional Crew
Now the other side of the line — repairs that change the structure’s geometry or load paths, needing a crew that does this every week:
- Full or partial house leveling: raising settled sections with hydraulic jacks, then setting new piers and permanent shims. The lift must be slow, even, and sequenced.
- Pier replacement: digging out failed piers and pouring or stacking new ones to proper depth and bearing. In Shreveport clay, pier depth and footing size are engineering decisions, not guesses.
- Beam and sill plate replacement: swapping main support beams or the sill where the house meets the foundation means temporarily carrying that load on cribbing. That temporary support is the dangerous part.
- Significant re-shimming (over an inch): large lifts redistribute loads across the whole frame and can crack drywall, rack doors, and stress plumbing if done out of sequence.
- Termite-damaged structural framing: once termites eat into beams or sills, remaining strength is unknown until a pro evaluates it.
The dividing principle: DIY reinforces, professionals re-level. The moment a bottle jack lifts any part of the house, you have crossed into structural work.
The Safety and Engineering Reasons DIY Leveling Goes Wrong
A house weighs tens of tons, and bottle jacks concentrate that weight onto a small point. Homeowners get hurt when jacks tip on soft soil — Shreveport’s wet-season clay is exactly the kind of soft that lets a jack lean and kick out — or when undersized temporary supports let the load shift mid-lift.
Houses are lifted in sequence, a little at a time, alternating across the foundation so the frame never twists. Lift one pier three inches while its neighbor sits still and you can rack door frames, pop drywall seams, and shear plumbing. Pros lift to an elevation plan; DIYers lift to “looks about right” — that is how secondary damage happens.
Crawl spaces add their own hazards: low clearance, poor air, mold, rodents, old wiring, even asbestos in older Shreveport homes. The OSHA confined spaces guidance is worth reading before a weekend under your house. If the space feels sketchy, trust that feeling.
What Professional Pier and Beam Repair Actually Looks Like
Knowing what the pros do helps you judge quotes. A professional leveling job starts with an elevation survey — readings across the floor on a grid, mapped so the crew knows how far each area dropped. That map becomes the lift plan.
On work day, the crew sets hydraulic jacks and timber cribbing under the beams, then raises the house slowly — often over multiple passes across two or more days. As each section reaches target height, they install new piers, set permanent steel shims, replace rotted beams or sills found along the way, and re-check elevations before cleanup.
Expect two to five days for most homes and $3,000 to $12,000 depending on pier count, wood replacement, and access. If you want the step-by-step version of the process, our guide to how to repair a pier and beam foundation walks through each phase in detail.
DIY vs. Pro: Cost Comparison
Money is usually what drives the DIY question, so here is an honest side-by-side. DIY looks cheap until a mistake multiplies the bill:
| Repair | DIY Cost | Pro Cost | Verdict |
|---|---|---|---|
| Sistering joists | $150–$400 in lumber and hardware | $800–$2,000 | Fair DIY project |
| Shimming low spots (under 1 inch) | $50–$150 in shims | $800–$2,000 | Fair DIY project |
| Vapor barrier and cleanup | $200–$500 | $1,000–$2,500 | Fair DIY project |
| Full house leveling | $500+ in rentals — plus real risk | $3,000–$12,000 | Hire a pro |
| Pier replacement | $300+ in materials — plus real risk | $2,000–$8,000 | Hire a pro |
| Beam or sill replacement | $400+ in lumber — plus real risk | $2,500–$10,000 | Hire a pro |
The hidden cost of DIY structural work is the do-over: a botched leveling that racks the frame or breaks a sewer line routinely costs more than the original pro quote. Our breakdown of how long pier and beam repair takes helps you plan around the disruption either way.
When to Call for a Free Inspection
Call a pro when the house needs lifting, piers are failing, rot or termite damage reaches structural members, or you are unsure which side of the line you are on. A free inspection with elevation readings answers the two questions that matter: how far out of level is the house, and what will it take to fix right.

Whether you end up hiring the work out or tackling the safe DIY pieces yourself, you will be deciding from real measurements instead of guesswork.
Frequently Asked Questions
Is it easy to fix a pier and beam foundation myself?
Parts of it are. Sistering joists, adding small shims, laying a vapor barrier, and replacing short runs of rim joist are fair DIY projects. Lifting the house, replacing piers, and swapping beams are structural work that belongs to a professional crew with jacks, cribbing, and a lift plan.
Can I use bottle jacks to level my own house?
You physically can, but you should not. Bottle jacks tip on soft soil, and lifting out of sequence racks the frame, cracks drywall, and can shear plumbing. Professional leveling uses cribbing, multiple jacks, and a sequenced lift plan for a reason.
What pier and beam repairs are safe for a homeowner to DIY?
Stick to work that does not change the height of the house or redirect structural loads: sistering joists, shimming under an inch, vapor barriers, crawl space cleanup, minor mortar touch-ups, and piecemeal rim joist replacement. If the project involves lifting anything, call a pro.
How much does professional pier and beam repair cost in Shreveport?
House leveling typically runs $3,000 to $12,000, pier replacement $2,000 to $8,000, and beam or sill work $2,500 to $10,000. Crawl space structural repairs range $2,000 to $10,000. Pier count, wood replacement, and crawl space access set the final number.
Is it dangerous to crawl under my house to do repairs?
It can be. Low clearance, mold, pests, old wiring, and poor air are common in older Shreveport crawl spaces. Wear a respirator, bring good lighting, never work alone — and if the space feels unsafe, stay out and call a professional.
Do I need a permit to repair a pier and beam foundation in Shreveport?
Structural work like leveling and pier replacement often requires a permit, while minor repairs usually do not. Rules vary between Shreveport, Bossier City, and the parishes, so check with the local permit office before structural work begins. A reputable contractor handles permitting as part of the job.
How long does professional pier and beam repair take?
Most leveling jobs take two to five days, pier replacement two to four days, and beam or sill work two to five days. Scheduling after the inspection usually runs one to four weeks out, and you can stay in the home during the work.
Will DIY repairs void a foundation warranty?
They can. Most structural warranties require that no one else alters the support system afterward. Check the terms before structural DIY — maintenance work is usually fine, but lifting or re-shimming can void coverage.
