Before the first panel

The finish starts before the first panel.

Wallpaper follows the surface beneath it. Adhesive, torn drywall paper, texture, loose paint and uneven repairs are assessed before installation.

  1. 01

    Surface assessment and repair

    Paint, drywall paper, old adhesive, cracks, ridges and texture are checked. Unstable finishes and uneven repairs are addressed before wallpaper is installed.

  2. 02

    Skim coating, sanding and suitable primer

    When required, damaged paper is sealed and the wall is skimmed, sanded or primed with a product suited to the wallcovering.

  3. 03

    Pattern, focal-point and seam layout

    Reference lines, pattern position and seam placement are planned around corners, openings and important room features before cutting.

  4. 04

    Careful trimming, cleanup and final review

    Panels are trimmed around ceilings, baseboards, casing and fixtures. The room is cleaned and the complete installation is reviewed.

Materials and applications

Wallcoverings we install

Product instructions, adhesive choice, wall suitability and site conditions are reviewed before the installation approach is confirmed.

01

Non-woven and paste-the-wall wallpaper

Product instructions determine the adhesive, booking and wall preparation required.

02

Vinyl and textured wallcoverings

Weight, backing, surface relief and cleanability all affect handling and adhesive choice.

03

Grasscloth and natural-fibre wallcoverings

Natural shading, visible panel character and variation can be inherent to the material rather than an installation defect.

04

Multi-panel murals and panoramic designs

Panel order, wall dimensions, centring, trimming allowance and focal points are checked before installation.

05

Peel-and-stick and pre-pasted wallpaper

These products still need a smooth, sound and suitably cured surface; they are not automatically easier to align.

06

Select commercial wallcoverings

Product specifications, site access and the intended application are reviewed before the work is accepted.

A clear four-step process

From wall photos to final review

Photographs can support an initial estimate. Complex walls, removals, high areas or specialty materials may still require a site visit.

  1. 01

    Send the walls and product information

    Share room and wall photographs, approximate dimensions, ceiling height, the product link or label, and any visible damage or old wallpaper.

  2. 02

    Review the material, condition and access

    Strataline reviews the material, pattern repeat, wall condition, openings, access and whether a site visit is needed.

  3. 03

    Protect, repair and lay out the room

    Adjacent finishes are protected, approved preparation is completed and panel positions are planned before cutting.

  4. 04

    Install, trim and review

    Panels are installed in the required sequence, trimmed around room details, cleaned and reviewed as a complete installation.

What affects the quote?

The wall, material and room shape all matter.

The scope is reviewed from actual conditions and product information—not a generic per-roll or square-foot rate.

    Wallpaper installation FAQ

    Useful answers before the first panel.

    Preparation, product information and room conditions determine the right installation plan.

    What affects the price of wallpaper installation?

    Wall size, height, access, preparation, material type, pattern repeat and the number of corners or openings all affect the work. A prepared feature wall is different from a stairwell needing removal and repair first. The quote should identify wall preparation and hanging separately from the supplied paper, with the product information reviewed before quantities or installation are confirmed.

    What information is needed for a wallpaper estimate?

    Send a full-room view, a straight-on photo of each wall, approximate widths and heights, ceiling height and the product link or label. Include roll dimensions, pattern repeat and photos of damage, texture or old wallpaper. Access, stairs and furniture also affect the work. The product information is as important as the wall area when assessing installation and material quantity.

    Do walls need primer before wallpaper installation?

    Often, yes. A wallpaper-compatible primer can seal porous repairs, create a consistent base and help with positioning and later removal. The right preparation depends on the existing paint, drywall condition and wallcovering instructions. Damaged drywall paper may need sealing before repair. Primer does not replace removal of loose paint or correction of a rough wall.

    How much wallpaper should I order?

    Use the exact wall widths and heights with the roll width, length and pattern repeat. Large repeats and drop matches can create more trimming waste because adjacent strips must align. Murals may be supplied as a fixed panel set. Check the product’s ordering guidance and allow matching material for trimming and future repair before placing the order.

    Can wallpaper cover a textured or damaged wall?

    Usually the wall needs correction first. Ridges, dents, torn drywall paper, uneven patches and loose coatings can show through wallpaper or weaken the bond. Preparation may include residue removal, sealing, repairs, skim coating, sanding and appropriate primer. A heavy-looking wallcovering should not be assumed to hide everything; its thickness does not make an unsound substrate suitable.

    Should the old wallpaper be removed before new paper is hung?

    Generally, yes. Removing the old paper and adhesive allows the underlying wall to be assessed and avoids depending on an unknown older bond. The exposed surface may need repairs, sealing or skim coating. Removal is a separate part of the agreed scope, because painted paper, multiple layers and damaged drywall can change the amount of preparation needed.

    What determines how long wallpaper work will take?

    Removal, wall correction, primer readiness, product type, pattern matching and access all affect the schedule. A sound feature wall and a stairwell with damaged paper beneath old wallpaper are very different scopes. We review the preparation before setting the installation sequence. Materials should be inspected and ready so an incomplete or damaged delivery does not interrupt hanging.

    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, abuse, inadequate maintenance, unrelated water intrusion, third-party damage, structural movement and client-supplied product defects.

    How do you plan a multi-panel wallpaper mural?

    We check the finished wall dimensions, panel sequence and product instructions before layout. The focal point, trimming allowance, corners, windows and fixed furniture all affect where the image should sit. Delivered panels are inspected for sequence, printing and shipping issues before hanging. A mural needs a complete layout plan rather than simply starting the first panel at the nearest corner.

    What should I expect from grasscloth or natural-fibre wallpaper?

    Natural-fibre wallcoverings can show shade differences, fibre variation and visible panel character as part of the material. They require careful handling and a suitably prepared wall. Send the exact product information so adhesive, cleaning limits and room conditions can be reviewed. If you want an almost invisible panel-to-panel appearance, confirm whether the chosen material can realistically provide it.

    Is wallpaper suitable for a bathroom or powder room?

    It can be, when the product, wall and expected humidity are suitable. Reliable ventilation and a sound prepared surface matter, and wallpaper should not be assumed appropriate for direct splash or wet zones. Review the manufacturer’s use and cleaning instructions before ordering. A decorative finish cannot solve continuing condensation, leakage or moisture damage behind it.

    When might liner paper be needed before wallpaper?

    Liner paper may form part of a specified wallcovering preparation system when the wall and selected finish warrant it. It does not replace repair of loose material, moisture damage or pronounced unevenness. The wallcovering instructions, adhesive compatibility and expected appearance guide the decision. We review whether lining, skim coating, priming or a combination is appropriate before ordering, rather than treating a liner as a universal way to cover a damaged wall.

    What is a pattern repeat or drop match?

    The repeat is the distance over which a design begins again. A drop match means neighbouring strips align at different vertical starting points, which can use more material than a simple area calculation suggests. The exact repeat and matching instructions guide cutting and layout. Share the label before ordering so the quantity accounts for the design, not just wall area.

    How do uneven walls and corners affect the pattern?

    Walls and corners are not always straight or square, so a pattern can drift if layout simply follows an existing edge. The wall is checked and the starting lines are planned before hanging. Some adjustment at corners or an unobtrusive finishing point may be necessary. Large geometric patterns make these room conditions more noticeable than an irregular design.

    Where should a patterned wallpaper installation start and finish?

    The starting point is chosen around the room’s focal wall, doors, windows and important sightlines. The final join may need to fall in a less prominent position because a room’s perimeter rarely equals an exact number of pattern widths. Discuss the focal point before installation. Starting at an arbitrary corner can create an awkward cut through the main design.

    Why might wallpaper seams remain visible?

    Seam appearance depends on the material, pattern, edge finish, wall flatness and lighting. Natural-fibre panels can show deliberate variation, while poor preparation or a product problem may create unwanted edges. We assess what is visible and why rather than promising that every material has invisible seams. Check the selected product’s appearance expectations before installation.

    Why should rolls come from the same batch?

    Different production runs can have visible colour or print differences even when the design name is unchanged. Check labels and inspect the material before installation, particularly when several walls will be seen together. Ordering sufficient matching material at the outset reduces the chance of relying on a later batch to finish the room or repair a damaged strip.

    Can one wallpaper adhesive be used for every product?

    No. The adhesive and application method must suit the wallcovering and the prepared substrate. Some products are pasted differently or require a particular system, so the exact instructions need review before installation. An adhesive that works with one paper is not automatically suitable for grasscloth, a mural or another backing. Product selection and wall preparation are considered together.

    Is peel-and-stick wallpaper automatically suitable for painted walls?

    No. The selected product still needs a compatible, clean, sound surface and any required paint-curing period. Texture, loose paint, contamination and room conditions can affect adhesion and removal. Send the product instructions and wall photographs for review. A removable label should not be taken as a guarantee that every existing paint or drywall surface will remain undamaged.

    Can wallpaper be hung on a ceiling or in a stairwell?

    Those areas can be reviewed, but they require suitable access and a product appropriate for the surface. Ceiling layout, overhead handling, tall walls and stair openings change the protection and fitting plan. Pattern alignment must account for the way the space is seen from below or across the stair. They are not priced like an easily reached rectangular feature wall.

    Can walls be painted after wallpaper removal?

    Yes, after adhesive residue and any damaged surface have been addressed. Paint over remaining paste or torn facing can produce an uneven or unreliable finish. The wall may need sealing, patching, skim coating and sanding before primer and paint. The removal stage reveals how much correction is required; stripping the visible paper alone does not make the wall paint-ready.

    What happens around outlets, switches and trim?

    The layout and finishing cuts need to respect the fixed details and the paper’s pattern. Plates and trim edges are reviewed as part of preparation so they do not leave rough borders. Electrical changes belong with the appropriate licensed trade. If new switches, fixtures or trim are planned, coordinate them before wallpaper so later work does not damage finished panels.

    How should wallpaper be cleaned or repaired after installation?

    Follow the selected wallcovering’s care instructions; scrubbing suitable for one product may damage a natural-fibre or delicate finish. Keep the product label and matching spare material for possible repairs. A damaged strip may need replacement through its full height to preserve the pattern. Report lifting or other unexpected changes so the cause can be assessed before an unsuitable repair is attempted.

    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 should we check with condo management before renovating?

    Ask about renovation approval, contractor documents, work hours, elevator and loading reservations, common-area protection, disposal and any water shutoff procedure. Flooring or exterior-opening work can require additional product approval. Share those requirements before ordering or booking construction; building permission and municipal or trade approvals are separate parts of planning.

    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.

    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.

    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.

    Can you install products I buy myself, and who covers them?

    We may install client-purchased doors, windows, flooring, tile, plumbing fixtures, lighting, hardware and similar products. We remain responsible for the workmanship of our own installation. You remain responsible for the product warranty, defects, missing components and compatibility.

    Replacement products and additional removal or reinstallation caused by a client-supplied product failure are chargeable. Such products can also affect price and schedule, so send the complete product information before buying or booking installation.

    Who handles a warranty claim for a product Strataline supplied?

    For a potential manufacturing defect within the applicable warranty period, we inspect the issue, document the condition, gather photographs and evidence, communicate with the supplier or manufacturer, and coordinate the claim for you. Strataline covers removal and reinstallation labour associated with a valid supplied-product warranty issue.

    The replacement product is governed by the manufacturer’s written warranty; approval is not guaranteed. If a claim is denied because we installed the product incorrectly, we correct our work.

    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.

    Do you have a minimum project size?

    We do not apply one universal project minimum. Small work may be accepted when it matters to the client, is technically demanding, supports accessibility, involves an existing client or is logistically practical. A defect only a few square inches in size can require protection, filling, sanding, priming, colour matching and repainting a larger plane so it does not look patched.

    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.

    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. These typical milestones do not retrospectively replace the payment terms in a signed project agreement.

    Is the scheduling deposit refundable before materials are ordered?

    No. The scheduling deposit reserves time for your project and is non-refundable, whether or not materials or products have been ordered. It is credited toward the agreed project price. If your timing changes, contact us early so we can review availability and confirm any agreed changes in writing. This does not limit cancellation or refund rights provided by applicable law.

    Can I change my project date after booking?

    You may request a different project date. The replacement date must fit around already confirmed work, and we offer the earliest mutually available date. Tell us as soon as the constraint becomes known so deliveries and access can be coordinated. Scheduling deposits remain non-refundable whether or not products have been ordered. We confirm any agreed scheduling changes in writing. Product-order payments are separate, and custom or special-order products already ordered remain subject to their ordering commitment. Applicable statutory cancellation or refund rights are preserved.
