Hardwood stair refinishing · Toronto & Vaughan
Restore sound hardwood stairs with careful repairs, dust-controlled sanding, on-site stain samples and durable protective finishes—without the disruption of full replacement.
Send wide photos of the full staircase and close-ups of the treads, landings and railing. We’ll review the likely options and confirm whether a site visit is needed.
King City project: the lower staircase was rebuilt beside a wider foyer opening while the remaining treads were repaired and refinished. View the full case study.
Start with the existing material
It depends on the tread material, remaining thickness, previous sanding, existing damage, and how the staircase meets the landings and railing.
Original Strataline work
Each staircase brings the treads, landings, railings and surrounding finishes into one coordinated plan.
Whole-home renovation
The staircase was refinished as part of a whole-home renovation that also included painting, popcorn-ceiling removal, main-floor tile replacement and a later stair-lift installation.
The finished black-and-white staircase became the visual centre of the renovated interior.
Mississauga · Four views
This Mississauga project included complete stair refinishing, new flooring, a herringbone installation, whole-home painting, coffered-ceiling painting and extensive trim work.
The refinished staircase connects the foyer, lower level and upper balustrade with one finish plan.
Mississauga
This project combined whole-home painting, refinishing of the visible staircase, hardwood capping on the basement stairs, and installation of new metal spindles and posts with gold inserts.
This staircase moved from the original finish through dust-controlled sanding to refinished stairs and posts with gold inserts.
Before and after
One staircase changed from golden oak to brown-stained treads and a white-painted base. The second combined dark refinished treads with new posts, metal spindles and OC-64 whole-home painting.
The right approach depends on the existing wood, its condition and the amount of railing work involved.
Main floor to basement
This project combined floor refinishing, stair capping, new posts and metal spindles, and refinishing of the existing handrail through the main stair opening and toward the basement.
The complete stair run and both guards had to be considered together.
Television-featured renovation
The staircase was refinished with new posts, metal spindles and a fitted runner. Wallpaper installation and interior painting were completed elsewhere in the home.
The runner was planned after refinishing so the tread finish, posts and railings remained visually connected.
Woodbridge
This whole-home project combined new flooring and painting with dark stair refinishing, white risers and stringers, and new posts and metal spindles.
The stair finish was coordinated with the new floors while the original staircase layout remained.
Dust control in an occupied Milton home
For this December project, a ZipWall enclosure turned part of the living room into a protected area for saws, materials and preparation. The temporary barrier kept the working zone separated from the occupied part of the home.
How stair refinishing works
Every staircase is different, but the work follows the same basic sequence.
Check the tread material, previous sanding, damage, movement, landings and railing connections.
Cover nearby finishes and separate the work zone from occupied areas where needed.
Sand the treads, handrail and other approved wood components using dust extraction and detailed edge work.
Address repairable holes, chips, cracks, loose areas and surface inconsistencies before staining.
Judge colour on the actual wood beside the surrounding floors and finishes under the home’s lighting.
Complete the approved finish coats and provide project-specific instructions for drying, traffic and full cure.
Project examples
These projects show how existing damage, railing work, stain matching and nearby finishes affect the final plan.
Condition assessment
Brampton
The original inquiry concerned a loose railing. After the staircase was assessed, the homeowners chose to refinish the stairs and complete new spindle and railing work at the same time.
A site assessment helps separate necessary repairs from optional finish and railing upgrades.
Connected railing work
Newmarket
Maxim installs a stainless-steel basement handrail during a Newmarket stair project. Railing work can be coordinated with refinishing and is quoted as a separate part of the project.

Practical answers about suitability, dust control, access, finish timing, runners, railings and preparing your home.
Existing planning ranges are $3,500–$6,500 for a standard staircase, $6,500–$10,000 for a large or curved staircase, and $8,000–$15,000 when refinishing is combined with upgrades. These ranges describe different scopes rather than fixed packages. Tread condition, repairs, stain development, handrails, paint work and access determine the written quote; confirm which components and finish stages are included.
Sound hardwood with enough material to sand may be suitable for refinishing. Carpet-grade, badly worn or unsuitable visible treads may be better candidates for fitted hardwood caps over a sound base. First assess the structure, finished step geometry and landings. The decision should preserve suitable components while addressing the actual condition, rather than covering a problem with a new surface.
It can include protection, repairs, removal of the old coating, sanding, stain samples, colour application, protective coats and painting of specified risers or stringers. Handrail and railing work need their own clear inclusions. Check whether the scope covers edges, landings and difficult junctions as well as the broad tread surfaces, since those details affect the finished result.
A close visual relationship is often possible through samples tested beside the installed floor. Species, wood age, sanding, existing colour, sheen and room lighting all affect the result. On the Bayview and Lawrence project, we corrected a mismatched red-oak staircase by developing the colour in the home and accounting for the topcoat. That project-specific process is not a universal stain formula.
Timing depends on repairs, component fitting, sample approval, coatings and the railing scope. We plan periods when the stairs must be clear and explain access restrictions before work begins. Light use, normal traffic and full finish cure are different milestones. A household that relies on the only staircase needs a workable access plan around those stages.
Remaining finish can block new stain and leave inconsistent absorption. Scratches, uneven sanding and earlier colour layers can also show through a new coat. For a true colour change, the surface needs a controlled starting condition. A simple maintenance recoat is a different scope and is only suitable when the existing finish and compatibility support it.
For applicable work such as ceiling removal, stair sanding, wall correction and painting preparation, our dust-free process combines containment, floor and furniture protection, HEPA extraction, Festool and Mirka sanding equipment, controlled sanding, air management, cleanup and inspection. The system captures sanding dust and protects occupied areas. Demolition and brick cutting still generate dust at the work point and need operation-specific containment.
We warrant our labour and installation to the original client for as long as that client owns the property, subject to the applicable manufacturer-warranty period for supplied products. Where no meaningful manufacturer warranty exists, workmanship coverage continues through the original client’s ownership. If a problem is caused by our workmanship, we return and correct it. Coverage ends when the property is sold or another contractor modifies or repairs the covered work.
The warranty covers genuine labour or installation defects. It excludes ordinary dirt, normal wear, accidental damage, misuse, inadequate maintenance, unrelated water intrusion, structural movement and client-supplied product defects.
Often, once the existing coating is removed and a sample is developed on the actual wood. Oak’s natural undertone remains part of the result, and darker colour can make uneven sanding more visible. We review the colour with the planned protective finish and adjacent flooring. Choosing a stain name alone does not establish how it will look in the home.
Possibly, depending on the exposed wood, previous colour penetration and the desired appearance. A clear finish can change the wood’s tone and contrast, so it should be reviewed on a prepared sample. Old deep stains, repairs and mixed species may remain visible. A light result needs assessment of the existing material rather than a promise that sanding makes all wood pale.
Not always. Sanding can reduce shallow discolouration, but contamination that has penetrated deeply may remain. The wood condition and available thickness need assessment before choosing a repair, a different colour direction or selective replacement. Removing more material indefinitely is not a suitable answer, especially at tread edges or areas that have already been sanded several times.
A tread may be unsuitable if it is too thin, deeply damaged, carpet-grade or no longer structurally sound. Previous sanding and edge wear also matter. We review what remains before choosing repair, caps or replacement. A new finish should not hide an unsafe or unstable base, and the surrounding step geometry must still work with the chosen correction.
Yes, where included in the scope and the existing surfaces are suitable. Preparation may involve filling, sanding, selective caulking and appropriate primer before the finish coats. The junctions with stained treads and trim need careful sequencing. White paint makes dents and rough repairs visible, so the amount of preparation should be agreed rather than assumed to be a quick overcoat.
Strataline uses new posts for railing renovations and does not refinish existing wood spindles. An existing handrail may remain if it is suitable for the new system. Connections, layout, condition and the intended finish all need assessment. The quote should state what is retained, removed and replaced so a new appearance does not depend on unsuitable old components.
Curved treads, exposed ends, custom nosings and changing railing angles require individual measuring and fitting. Open sides also make underside and edge details visible. Landings and leading steps must relate to the whole flight. These conditions can add fabrication and finishing work even when the tread count is similar to a straightforward closed stair.
Often, but the cause and available access determine the repair. Movement may come from tread connections, gaps, loose layers or broader structural conditions. A cap or fresh coating does not automatically stop it. We assess the affected area before finishing and identify any repair that requires opening the underside or replacing an unsuitable component.
Plan both together so removal, new post locations, holes, handrail finishing and baluster installation do not damage a completed surface. Some components need fitting before finish coats while others are installed afterwards. The sequence depends on the chosen system. Separate trade visits without a shared plan can leave avoidable patches or require reworking the new finish.
Follow the timing for the selected coating and the actual drying conditions. Light access, full household traffic and complete cure are not the same stage. Pet claws, shoes and carried furniture can mark a young finish even when it feels dry. We explain the restrictions for the agreed system before the work so household access can be planned.
Sometimes, if the existing finish is sound, compatible and suitable for the preparation required. Wear through the coating, deep contamination or uneven colour may need more complete refinishing. The assessment separates a protective maintenance coat from a colour correction. Simply coating over dirt, damage or an unknown failing finish can leave the original problem visible.
Send wide views from the top, bottom and side, plus landings, open ends, posts, handrails, balusters and close-ups of damage. Include the tread count and the floor or finish you want to coordinate. Photographs help identify the likely approach; final measurements and concealed connections may still need an on-site assessment before fabrication or a firm scope.
Inspection lighting helps expose surface defects on ceilings, walls, paint and wood that can be missed in general room light. We also take a client’s lighting-dependent concern seriously. In one case, we returned to refinish a piece with a subtle reflected sanding pattern, inspected it from multiple light angles and completed the correction without charge. Natural wood still varies with grain and lighting.
A failure caused by faulty preparation or application may be covered as workmanship. Ordinary dirt, scratches and wear from use are not workmanship defects. We inspect the condition and investigate the cause rather than automatically blaming the client or the product. Moisture sources, maintenance, movement and any later alterations help determine why the finish changed.
Let us know what changed, when it appeared and where it is, with wide and close photographs if possible. Do not assume that a small or lighting-dependent flaw is unimportant. After more than 15 years in business, workmanship callbacks are rare, but we still investigate reported issues and return to correct genuine defects caused by our work.
Temporary barriers and protected circulation routes separate active work from adjoining rooms, while connected extraction captures dust where sanding occurs. An open stairwell, double-height space or kitchen connection changes how containment can be arranged. The work sequence and air management are planned with those openings in mind, rather than relying on floor covering alone.
A clear room gives the best working access, but the plan depends on what can reasonably be moved. We identify items to relocate, protect remaining furniture and floors, and keep a usable route outside the work zone. Fragile possessions need particular attention. Protection and handling are included in the scope according to the actual room, not assumed from its floor area.
Often, with a practical plan for usable rooms, protected circulation and temporary restrictions. The answer depends on the scope, drying stages and whether essential stairs, the kitchen or the only bathroom must close. We discuss those interruptions before scheduling. A contained work zone still needs to remain clear of household traffic while work is underway.
A requested change needs a clear description of what is being added, removed or substituted, together with the price and scheduling effect. We review it before the changed work proceeds. Even a small visible change can affect ordered materials or another trade, so decisions are recorded against the written scope rather than left to an informal assumption.
A typical larger project uses 30% when booked or products are ordered, 30% when products arrive at the client’s property, and 40% following installation and completion. These terms are flexible, not mandatory for every project. The individual written agreement controls and identifies the milestones so payment follows the agreed purchasing and construction plan.
Deposits are refundable before materials or products are ordered. Custom and special-order products become non-refundable once ordered, so confirm the selections and ordering status when discussing a cancellation. The deposit also reserves the project date. The written agreement should identify the ordering status and the commitments already made.
Written quotes are normally valid for 30 days unless the quote states otherwise. Public website price ranges are before HST. Supplier pricing and availability can change after a quote expires, so an older estimate should be reconfirmed before products are ordered or a date is booked. The current written agreement sets the amount and terms for your project.
Often, yes. We can review product suitability and coordinate ordering with the installation, and we can often obtain better trade pricing. That is not true for every product, so compare the actual supplied scope and price. Supplying the product also lets us coordinate a potential manufacturer claim during the applicable warranty period, including our stated removal and reinstallation responsibility.
The work zone and protected access route are cleaned, the finishes are inspected, and any outstanding scope items are reviewed before handover. Protection removal is sequenced so debris does not get dragged through finished rooms. Daily cleanup and final completion serve different purposes: a tidy intermediate work area can still need curing time or another finishing stage.
