Start with the existing material

Can your existing stairs be refinished?

It depends on the tread material, remaining thickness, previous sanding, existing damage, and how the staircase meets the landings and railing.

Usually suitable

  • Existing solid hardwood treads
  • Worn or dated finish
  • Scratches and normal wear
  • Repairable dents, chips or staple holes
  • Structurally sound staircase
  • Handrails and posts that can be coordinated with the treads

Requires assessment

  • Heavy previous sanding
  • Deep contamination or water staining
  • Pet damage
  • Loose treads or significant movement
  • Major colour change or mixed wood species
  • Replacement components, difficult landings or transitions

Usually better suited to another approach

  • Carpet-grade construction treads
  • Thin or unsuitable tread material
  • Severe damage
  • Major structural or geometry changes
  • Treads that are better suited to hardwood capping than further sanding

Dust control in an occupied Milton home

A protected work zone for stair refinishing

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.

  • The work zone was separated from the occupied living area.
  • Saws, materials and preparation remained inside the enclosure.
  • The staircase was completed shortly before Christmas.
ZipWall containment separated the temporary work area from the occupied living space.

How stair refinishing works

A careful process from assessment to final finish

Every staircase is different, but the work follows the same basic sequence.

  1. Assess the existing stairs

    Check the tread material, previous sanding, damage, movement, landings and railing connections.

  2. Protect and contain the work area

    Cover nearby finishes and separate the work zone from occupied areas where needed.

  3. Remove the existing coating

    Sand the treads, handrail and other approved wood components using dust extraction and detailed edge work.

  4. Complete repairs and preparation

    Address repairable holes, chips, cracks, loose areas and surface inconsistencies before staining.

  5. Review stain samples in the home

    Judge colour on the actual wood beside the surrounding floors and finishes under the home’s lighting.

  6. Apply protective finishes and plan access

    Complete the approved finish coats and provide project-specific instructions for drying, traffic and full cure.

FAQ

Stair refinishing questions

Practical answers about suitability, dust control, access, finish timing, runners, railings and preparing your home.

How much does stair refinishing cost?

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.

Should I refinish the stairs or install hardwood tread caps?

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.

What does a complete stair-refinishing scope include?

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.

Can a staircase be matched to an existing hardwood floor?

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.

How long will stair work take, and when can we use the stairs?

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.

Why remove the old coating before changing stair colour?

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.

What does Strataline mean by dust-free renovation work?

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.

What does Strataline’s lifetime workmanship warranty cover?

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.

Can orange or golden oak be stained darker?

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.

Can stairs have a light natural finish instead of stain?

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.

Will sanding remove dark pet stains completely?

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.

When is a tread too worn or damaged to refinish?

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.

Can risers and stringers be painted white?

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.

Which existing railing components can be reused?

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.

What makes curved or open-sided stairs more involved?

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.

Can squeaky or loose stairs be repaired?

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.

When should railing work happen relative to refinishing?

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.

When can pets, shoes and normal traffic return to refinished stairs?

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.

Can a worn stair finish be recoated without changing its colour?

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.

Which staircase photos help you prepare a useful estimate?

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.

Why do you inspect finishes under special lighting?

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.

How do you distinguish a finish defect from normal wear?

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.

What should I do if I notice a problem after completion?

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.

How do you contain sanding work in an open-plan home?

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.

Does furniture have to leave the room?

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.

Can we stay in the home during a renovation?

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.

What happens when removal exposes hidden damage?

We document the condition and explain what must be addressed before covering it. Rot, loose substrates, old leaks or concealed movement can change the preparation and construction scope. Additional work is discussed with the client before it proceeds, including the repair approach and its effect on price and sequence. A new finish should not conceal an unresolved cause.

How are changes to the agreed work handled?

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.

What payment schedule do you normally use?

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.

Is my deposit refundable before products are ordered?

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.

How long is a quote valid, and are website prices before tax?

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.

Is it worth asking Strataline to supply the materials?

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.

What cleanup and inspection happen before a room is handed back?

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.
