What this work covers
Good wallpapering begins below the wallpaper. The old finish is removed, damp and damaged areas are dealt with, joints and hollows are repaired, and lining paper creates a stable base. Only then is the finish paper cut, allowed to relax with paste, aligned vertically, and dried slowly.

When this work is needed
Choose it to change a room's colour and texture or replace stained, torn, or dated wallpaper. If black mould or a damp mark is present, identify the leak or condensation source first. Covering the symptom only gives the stain a new surface to return through.
Decide before installation
Choose the preparation standard with the wallpaper, not after the old finish has been stripped.
- Wallpaper product, feature walls, pattern direction, and batch quantity for each room
- How much existing paper will be removed and which cracks, hollows, or mould-affected areas will be repaired
- Where lining paper or local reinforcement is required
- Edges at frames, windows, switches, and skirtings, plus the drying and ventilation plan
Check in the quote
Look beyond the roll price and confirm the work that will remain hidden behind it.
- Are removal, disposal, and difficult residual layers included?
- Is the repair scope for mould, cracks, and uneven walls stated?
- Will lining and reinforcement areas be agreed after the wall is exposed?
- Are cuts around frames, switches, and windows, paste cleanup, and return repairs included?
- Are product codes, quantities, batch consistency, and spare-roll handover recorded?
With wall photographs, samples, or a quote, I can help judge the preparation and lining work your rooms actually need.
What to check on site
Inspect each layer before the next one hides it.
- Existing Wallpaper Removal and Substrate Prep Complete

After stripping, look for dark mould, active damp, deep cracks, and broad level changes. Resolve the cause and agree the repair before any new layer is applied. - Lining Paper Installation Complete

The lining layer should bridge repaired joints and fixing marks without loose edges. Let it dry taut so movement in the wall is not transferred directly to the finish paper. - Wallpaper Cutting and Relaxing Complete

For patterned wallpaper, check that repeats are matched before cutting. Pasted lengths need the product's recommended relaxation time and should not be prepared so far ahead that the edges dry out. - Finish Wallpaper Applied

The first length sets every seam that follows. Confirm it is plumb, seams meet without overlap, and cuts around frames and switches are clean. - Inspection, Curing, and Cleanup Complete

Use side light to inspect colour variation, open seams, paste marks, and knife damage. Clean paste while fresh, then let the room dry gently without strong cross-draughts.
Where problems usually start

- Seams that open after drying An unstable lining layer or rapid drying can shrink apart seams that looked closed during installation.
- Colour change and lifting at seams Overlapped vinyl wallpaper or mixed production batches can make the joint read as a different thickness or shade.
- Mould and stains returning A leak or condensation path left unresolved will discolour the new paper and can bring the odour back.
- Outer corners splitting Pulling paper tightly around a sharp external corner stretches it; drying then concentrates stress along the fold.
- Edges peeling away Strong ventilation immediately after installation dries exposed edges first, causing releases around frames and skirtings.
Minor damp wrinkles often relax as the wall dries. A seam that is already open or a wet stain showing through needs investigation rather than more waiting.
Retain the product and batch code, spare paper, photographs of the exposed substrate and lining, and full-wall and seam photographs after drying.
Timing and records
Allow about 16 to 24 hours of site work. Poor substrates add removal and repair time, while lining and finish-paper drying extend the elapsed programme beyond the labour hours.
Record each room's wallpaper code, substrate repairs, lining condition, first-strip alignment, seam inspection, installation date, and where the spare material is stored.
Ceiling sheets usually finish first, while flooring and skirtings determine the lower edge. Review all three handoffs before fixing the final sequence.
