Wallpaper Installation and Removal Guide

For many UK homeowners, the daunting task of removal—often involving layers of stubborn Victorian paper or woodchip—is the primary hurdle. Professional decorators bring the right equipment and patience to ensure your walls are perfectly primed, preventing common issues like peeling seams or unsightly bubbles.

What Does the Work Involve?

• Site Assessment: Checking the wall condition for damp, blown plaster, or uneven surfaces that require remediation.
• Removal: Using industrial steamers or enzyme-based stripping solutions to remove old paper without damaging the plasterboard or render.
• Surface Preparation: Filling cracks and holes, sanding the surface smooth, and applying a "size" (a thinned adhesive) to seal the wall.
• Lining Paper: Often recommended in older UK homes to provide a smooth, absorbent base for the decorative top layer.
• Pattern Matching: Calculating the "drop" of the pattern to ensure a seamless transition across joins.
• Adhesive Application: Applying the correct paste (ready-mixed or flake) depending on whether the paper is "paste-the-wall" or traditional.
• Hanging and Trimming: Precise vertical alignment using a plumb line, followed by expert trimming at the ceiling, skirting, and around sockets.

Typical Costs

Prices vary significantly based on the type of paper you choose. Hand-printed papers or heavy vinyls require more time and specialist adhesives, whereas standard "paste-the-wall" products are quicker to install. Always clarify if the quote includes "making good" the plasterwork after stripping.

Professional decorators often charge more for removing woodchip wallpaper, as it frequently hides poor-quality plaster and takes twice as long to steam off.

How Long Does It Take?

• Stripping a standard room: 1 day (can increase if multiple layers are found).
• Preparing and lining: 0.5 to 1 day (including drying time for filler and size).
• Hanging a feature wall: 3 to 5 hours.
• Hanging a full standard room: 1 to 2 days depending on pattern complexity.
• Drying time: 24 to 48 hours before replacing furniture or installing shelving.

DIY or Professional?

Stripping wallpaper is a task many homeowners choose to tackle themselves to save money. While labour-intensive, it requires little technical skill beyond patience. However, hanging the new paper is a different story. Achieving perfectly invisible seams and exact pattern matches around awkward corners, radiators, and bay windows requires significant experience.

If you are using expensive designer rolls (upwards of £80 per roll), the cost of a mistake far outweighs the price of hiring a professional. While there are no specific UK statutory regulations like Gas Safe for wallpapering, a professional ensures the work meets the British Standard for painting and decorating (BS 6150).

Choosing the Right Tradesperson

• Check Credentials: Look for members of the Painting and Decorating Association (PDA) or those with City & Guilds qualifications.
• Portfolio: Ask to see photos of previous pattern-matching work, specifically around tricky areas like chimney breasts.
• Insurance: Ensure they have Public Liability Insurance to cover any accidental damage to your flooring or furniture.
• Red Flags: Be wary of anyone who suggests papering over old wallpaper or refuses to use lining paper on uneven walls.

Questions to ask:

• "Do you include the cost of the adhesive and lining paper in your quote?"
• "How do you handle 'blown' plaster if you find it after stripping?"
• "Will you remove the radiator or paper behind it?"
• "What is your policy if the seams begin to lift after a week?"

UK Regulations

• Lead Paint Safety: In homes built before 1960, old paint layers under wallpaper may contain lead. Professionals should follow HSE guidelines for dust suppression.
• Waste Disposal: If your decorator is disposing of the old paper, they must have a valid Waste Carrier Licence.
• Building Regs: Generally not applicable, though fire-rated wallpaper is required in certain commercial settings or communal hallways in flats.

Common Problems

• Bubbling: Often caused by trapped air or failing to let the paper "soak" for the correct time before hanging.
• Shrinking Seams: If the room is too hot or the paper is over-stretched during hanging, gaps will appear between drops as the paste dries.
• Pattern Misalignment: Usually occurs when the first drop isn't perfectly plumb (vertical), causing the error to magnify across the wall.
• Show-through: Using thin wallpaper on a dark or stained wall without lining paper first can lead to "ghosting" of the old surface.

Frequently Asked Questions

Do I really need lining paper?

While not always mandatory, lining paper is highly recommended for UK homes with older plaster. It smooths out imperfections, prevents the decorative paper from shrinking, and provides a uniform porosity for the adhesive.

Can you wallpaper over painted walls?

Yes, provided the paint is sound and not flaking. Glossy surfaces must be sanded to create a "key," and the wall should be cleaned with sugar soap and "sized" before hanging.

Why is my wallpaper peeling at the top?

This is usually due to insufficient paste at the edges or "sizing" not being applied to the wall. It can also happen if the room has high humidity or damp issues near the ceiling line.

How many rolls of wallpaper do I need to buy?

You must measure the width and height of each wall. Most UK rolls are 53cm wide and 10m long. Always allow an extra 10-15% for the "pattern repeat" and potential mistakes; it is vital that all rolls come from the same "batch number" to ensure colour consistency.

Can you wallpaper a bathroom or kitchen?

Yes, but you must use specialist "splash-proof" or vinyl wallpapers designed for high-humidity environments. Standard paper will eventually peel or develop mould in these rooms.
