Stair repair done to structural standard

A stair that squeaks or wobbles isn't just annoying. It's a load-bearing assembly under daily stress, and the longer it moves, the more the surrounding structure moves with it. Stair repair starts with diagnosing what's actually failing, tread, riser, stringer, subfloor connection, or the concrete itself, before a single board comes off. Strictly Builders Inc has handled stair repairs across wood, concrete, and mixed-material staircases on both residential and commercial properties. Call for a free look before the damage spreads to the framing underneath.

What drives cost on a stair repair job is scope and substrate. Replacing two loose treads on a straight run is a half-day job. Sistering a cracked stringer, reworking the newel post connection, and refinishing the full flight is a different project entirely. Concrete stair repair adds the question of whether the step face is spalling on the surface or whether the substrate is compromised. Material condition, staircase configuration, and what finish you're returning to all move the number. Every job is different, contact Strictly Builders Inc for an accurate estimate.

What stair repair actually covers

Most stair failures fall into a handful of categories. Knowing which one you have determines the fix.

01

Loose or Squeaking Treads

Treads work loose when the adhesive fails, fasteners back out, or the subfloor connection shifts. We re-secure from below where possible, add blocking where needed, and eliminate the squeak at the source rather than caulking over it.

02

Cracked or Spalling Concrete Steps

Concrete step faces crack from freeze-thaw cycles, impact, or poor original mix. Surface-only spalling gets a polymer-modified repair mortar. A compromised substrate needs the step rebuilt. We don't patch over structural failure.

03

Damaged or Cracked Stringers

The stringer carries the load. A cracked stringer isn't cosmetic. It's a structural failure. We sister the damaged member or replace it, depending on how far the split runs and what the floor framing below will support.

04

Riser Gaps and Sagging Risers

Open or sagging risers usually mean the stringer has shifted or the original installation skipped proper fastening. We pull the riser, address what caused it to move, and reinstall with the right fasteners for the material.

05

Newel Post and Railing Failures

A wobbly newel post is a code issue, not just a finish issue. We recore the connection into solid framing rather than relying on surface fasteners that pull free under lateral load.

06

Stair-to-Subfloor Connection

Where the staircase meets the subfloor at the landing, movement in one transfers to the other. We inspect both, address the connection, and stabilize the stair base before finishing the surface repair.

Our Process

How a stair repair job runs

Three stages, no surprises.

  1. 01

    Diagnosis First

    We walk the stair, load each tread, check the stringers from below, and identify every failure point before any work starts. You get a clear scope before a single fastener moves.

  2. 02

    Structural Repair

    Load-bearing elements get addressed first. Stringers, subfloor connections, and post footings are stabilized before any finish work happens. The sequence matters.

  3. 03

    Surface and Finish

    Once the structure is solid, we match the finish, tile work, wood, carpet, or concrete resurfacing. If the rest of the stair needs refinishing to match, we handle that in the same visit.

When to call a contractor , not attempt the fix yourself

  1. 01

    Call Strictly Builders

    Stringer damage, newel post connection failures, concrete substrate problems, stairs that move under load, or any repair where the finish has to match the rest of the flight. These need a contractor with the right tools and the right materials.

  2. 02

    You Can Handle It

    A single tread that's popped loose on a glue-down installation, surface-level cosmetic scratches, or a simple tightening job on a balusters that are still fully anchored.

  3. 03

    When You're Not Sure

    If you've pulled the tread and found rot, if the stringer has a visible crack, or if the stair moves laterally at all, stop and call. What looks like a tread repair is often a stringer repair once you're in there. Catching it early keeps the scope manageable.

One contractor handles the full stair scope

A stair repair rarely ends at the stair. It connects to the flooring at the top landing, the subfloor at the base, and sometimes the drywall on the stringer wall. Most contractors hand you off the moment the work crosses into a different trade. Strictly Builders Inc doesn't work that way. Ryan Alson has been in the trade for three years and handles the full scope in-house: structural repair, subfloor work, finish carpentry, tile, and surface refinishing. One call, one crew, one project. We've completed stair repairs for homeowners in Orange Park, Fleming Island, St. Johns, and across the region. If the job also touches a bathroom threshold, a hallway, or a remodeling project in progress, we fold it in rather than leaving you to coordinate another contractor.

Stair repair questions, answered directly

How do I know if my stair stringer is damaged?
A cracked or failing stringer usually presents as a stair that bounces or sags under your weight, a visible crack running diagonally along the stringer, or treads that are no longer level even after you've tightened them. If the stair moves laterally when you push the handrail sideways, the stringer or its connection to the floor framing is compromised. Don't ignore lateral movement. It means the load path is broken.
Can a cracked concrete step be repaired or does it need replacing?
It depends on depth. A surface crack or spalling face can be repaired with a polymer-modified mortar that bonds to existing concrete and holds up under foot traffic. If the crack runs through the full depth of the step, or if the rebar inside has corroded and expanded (which is what causes surface blowout on older steps), the step needs to be rebuilt. We'll tell you which one you have before we touch it.
What causes stair treads to become loose over time?
The most common cause is the original adhesive failing, either a poor-quality product, insufficient coverage, or a subfloor that wasn't fully flat before installation. Fasteners back out when the wood cycles through humidity changes seasonally. High traffic accelerates both. Glue-and-nail installation done right the first time holds for decades. Glue-only on an uneven surface fails within a few years in Florida's humidity.
Do stair repairs require a permit in Florida?
Cosmetic repairs to existing treads and risers, replacing a damaged board, re-securing a loose tread, typically don't require a permit. Structural repairs that involve sistering or replacing a stringer, modifying the stair configuration, or altering the railing to meet current code may trigger a permit requirement depending on the scope and municipality. Strictly Builders Inc will identify permit requirements before work starts, not after.
How long does a stair repair take from start to finish?
A focused repair on two or three treads with no structural damage usually runs four to six hours. A full stringer repair, subfloor connection work, and finish refinishing on a full flight can take two days. Concrete step repair depends on cure time, the mortar needs 24 hours before you put full foot traffic on it. We'll give you a realistic timeline at the estimate stage so you're not surprised mid-project.
Can you match the existing stair finish after a repair?
Usually, yes, though a perfect match depends on the age of the existing finish and whether the same material is available. For hardwood, we can refinish the repaired section and blend it into the existing stain. For carpet installation, we'll match the material as closely as possible. For tile, we need a sample or a tile from the existing installation to source a match. We'll be direct with you about what's achievable before we start.
