Structural Repairs · O'Fallon & St. Charles County
Fixing the parts that hold your house up.
Rotted subfloors, sagging joists and decayed sill plates don't fix themselves. We find how far the damage goes and repair it properly.
Structural Repairs
Structural damage rarely announces itself. It starts as a floor that feels a little soft near the tub, a door that suddenly sticks, or a slight dip you notice walking across the kitchen. Underneath, water may have been working on the subfloor or the joists for years. The longer it goes, the more wood has to come out.
Shane traces the damage to where it ends, not just where it shows. He'll get into the crawlspace or basement, probe the joists and sill plate, and pull back siding if the rim joist is suspect. Then he explains what he found, what caused it, and what it will take to make it right. You'll know the full scope before work begins.
We repair rotted subfloors, sister or replace sagging and damaged joists, replace sill plates and rim joists, and rebuild framing around old leaks. When a problem involves the foundation itself or calls for an engineered repair, we bring in a structural engineer and build to their specifications. That goes for older homes in historic St. Charles and newer subdivisions alike.

What's included
Every part of the job, handled.
- 01
Subfloor replacement
Rotted or delaminated subfloor cut back to sound wood and replaced, most often around toilets, tubs, dishwashers and exterior doors.
- 02
Joist repair and sistering
Sagging, cracked or over-notched joists reinforced by sistering new lumber alongside them, or replaced outright when the damage goes too far.
- 03
Sill plates and rim joists
Rotted sill plates and rim joists replaced in sections, with the house supported temporarily while the new wood goes in.
- 04
Framing repairs
Walls, headers and studs rebuilt where leaks, insects or careless past remodels left them weakened, so the structure carries its load again.
- 05
Exterior structural repair
Rotted wall sheathing, porch framing, posts and beams repaired outside, where rain and freeze-thaw cycles do the most damage.
- 06
Engineer coordination
When foundation movement or a larger issue calls for an engineered fix, we work with a structural engineer and build to that plan.
From a real customer
“He is truly the old fashion worker your grandparents tell you about from back in the day.”
Read every reviewShane is the most professional contractor I have ever interacted with for a job. From the first time calling him to the time he left my property he was 100% sincere with everything he did. We requested to put on a new roof on a shed and fix a rotted floor. He recommended putting some extra TLC into the shed including siding and some other work. We didn't think it was possible due to the age of the shed. When he hit some roadblocks with extra issues dealing with the project, he kept his cool. He even worked in a non-shaded area, with a heat index over 110 degrees with no breaks. His employee had the same mentality and I could see his dedication as well. He was younger in age, but Shane educated him along the way. I could tell he was helping to shape the next generation of contractors. Shane was trying to put the love of the work back into the job rather than just completing the work. He told us the new problems we didn't know about and quickly addressed them. He didn't get upset by me asking questions and even gave detailed answers to my questions. If you want a person who shows the ability and love of his work, hire this company. I felt as if I hired a family member even though we never met before since he truly took ownership of his work. His prices are beyond reasonable and he doesn't charge for an extra screw or a random material other contractors charge customers. He is truly the old fashion worker your grandparents tell you about from back in the day. When I discussed future jobs with him he gladly said he would handle it. No job is too big or small for Shane. If someone would ask if I would hire him back, I would say 100%. He even warranties his work for years and you can't beat it.

FAQ
Structural Repairs:
common questions
Still wondering about something? Call or text Shane at (636) 306-0393.
Are you a structural engineer?
No. We're builders who regularly repair framing, subfloors, joists, sill plates and rim joists. When a problem involves foundation movement, a significant change in load, or anything that needs engineered drawings, we bring in a licensed structural engineer and build to their specifications. Shane will tell you plainly when he thinks an engineer's opinion is needed.
How do you know how far the rot goes?
We probe the wood with an awl or screwdriver, look at it from below in the basement or crawlspace, and open up finished surfaces when we have to. Rot often runs farther than the visible stain. We keep removing material until we reach solid wood on every side, so the repair ties into something sound.
Can you fix a sagging floor without tearing up the room?
Often, yes. If the sag comes from undersized or damaged joists, we can usually work from the basement or crawlspace, sistering new joists or adding support without touching the finished floor above. If the subfloor itself is rotted, that section has to come up. Shane will tell you which repair your floor needs after he sees it from below.
Will structural repairs need a permit?
Some will, depending on your city and the scope. Small repairs often don't, while replacing joists, headers or load-bearing framing often does. Each municipality in St. Charles County sets its own rules, so we check for your address rather than assume. When a permit and inspection are required, we handle both as part of the job.
