What stair recapping actually is
Recapping leaves the existing stringers, framing and rough treads in place and clads them with new pre-finished hardwood treads, risers, returns and skirt boards. The result looks like a brand-new staircase, but the structural carriages — and the floor framing they tie into — are never disturbed. For most St. Catharines homes built between 1950 and 2010, recapping turns a tired, carpeted utility flight into the focal point of the entry hall in 2–3 days, at roughly half the cost of a full rebuild.
Common Niagara repairs we handle
Squeaks and creaks — typically caused by tread/stringer separation as decades-old framing dries; we fix from above using calibrated wedges and structural adhesive. Cracked or split treads — single-tread replacement matched to species and stain. Loose newels and balusters — re-pinned, re-glued, or replaced where required by OBC guard-load demands (1.0 kN at the top rail). Worn or damaged nosings — replaced individually rather than re-running the whole flight. Refinishing — sand, stain and seal in place when treads are still structurally sound.
Recap, repair or rebuild — reading your staircase
Recapping makes sense when the underlying structure is sound: stringers straight, bearing points solid, geometry within 5 mm of uniform rise-to-rise. A targeted repair is enough when damage is isolated — a single split tread, a loose post, a persistent squeak confined to one section of the flight. A full rebuild earns its cost when the carriage itself has failed, when you want to change the staircase configuration, or when a major renovation is already moving the landing. We assess every staircase before quoting, and we'll tell you honestly which path fits. For a detailed side-by-side — including real St. Catharines examples of each outcome — see our stair recapping vs replacement guide.
Material choices for recapping
Every recap begins with one decision: species, profile and finish. Red oak is the most common choice across St. Catharines and Niagara Falls because it matches the existing oak flooring in most postwar homes and holds up to Ontario's humidity cycles without cupping. White oak with a wire-brushed finish has overtaken red oak in newer Niagara-on-the-Lake builds. For period properties in old downtown St. Catharines and Welland, we also work in maple, walnut and reclaimed pine. Treads are 25 mm thick (1 inch nominal) full-stave, never finger-jointed, and pre-finished with three coats of UV-cured polyurethane in our shop before installation.
Code, safety and what we check first
Adding a 19–25 mm cap to existing treads changes the rise of the first and last steps unless the landing is also re-leveled. Before we quote, we measure every rise — OBC 9.8.4 limits variation to 5 mm across the whole flight. We also check headroom (1950 mm minimum), nosing projection (≤25 mm), and guard heights. If anything is non-compliant we surface it before contract, not after.
Recent repair projects
Full oak recap of a 14-step carpeted flight in north St. Catharines (2025); single-tread walnut replacement in a Welland heritage home (2025); squeak-elimination on a 1970s split-level in Thorold (2024); balustrade rebuild with code-compliant guards on a Niagara Falls rental property pre-resale (2024). The postwar housing stock in Thorold — split-levels and ranch-styles with carpeted flights installed in the 1960s and 70s — is where we do some of our most satisfying recap work: the carriages are almost always sound, and a two-day recap transforms them entirely.
