Residential and Commercial Painting Guide

While many homeowners attempt DIY, professional decorators bring specialist equipment and years of experience in surface preparation. This guide outlines what to expect when hiring a pro, from current UK market rates to the essential regulations governing the trade.

What Does the Work Involve?

• Surface Assessment: Checking for damp, blown plaster, or wood rot that needs addressing before paint is applied.
• Preparation: Deep cleaning surfaces, stripping old wallpaper, sanding wood, and filling cracks or holes for a smooth finish.
• Protection: Laying heavy-duty dust sheets and using precision masking tape to protect flooring, furniture, and fixtures.
• Priming and Undercoating: Applying specialist base layers to ensure topcoat adhesion and block stains.
• Application: Using brushes, rollers, or HVLP sprayers to apply multiple coats of emulsion, eggshell, or gloss.
• Snagging and Cleanup: Final inspections to ensure crisp lines and a thorough site clear-up, including the removal of all waste.

Typical Costs

Pricing for painting and decorating varies significantly based on your location in the UK and the condition of the walls. Preparation work often accounts for 60-70% of the total labour time.

Prices generally include VAT if the contractor is VAT-registered. Always clarify if the quote includes the cost of the paint itself or if you are expected to provide it.

How Long Does It Take?

• Small Bedroom/Office: 1–2 days (including drying time between coats).
• Average 3-Bedroom House (Internal): 5–8 days depending on the number of decorators.
• External Masonry: 3–5 days (heavily dependent on UK weather conditions).
• Feature Wall Wallpapering: 3–5 hours.

DIY or Professional?

Painting is the most common DIY task, but the "pro finish" is difficult to replicate without the right tools. Professionals use industrial sanders with dust extraction, high-end fillers that don't shrink, and trade-grade paints that offer better coverage and durability than retail versions.

For commercial properties or rental HMOs, hiring a professional is often a legal or insurance requirement to ensure fire-rated coatings are applied correctly.

Choosing the Right Tradesperson

• Check Credentials: Look for membership in the Painting and Decorating Association (PDA) or the British Decorators Association.
• Insurance: Ensure they hold Public Liability Insurance (minimum £1 million) to cover any accidental damage to your property.
• Ask for Portfolios: A reputable decorator will have a gallery of recent local work or a social media profile showcasing their finishes.
• Key Questions:
  • How many coats of paint are included in the quote?
  • What brand of paint do you typically use?
  • How do you handle furniture moving and protection?
  • Is waste removal included in the price?

UK Regulations

• VOC Regulations: Since 2010, UK law has strictly limited Volatile Organic Compounds in paints; your decorator should use compliant, low-odour products.
• Working at Height: Contractors must follow the Work at Height Regulations 2005, using secured ladders or scaffolding for external work.
• Lead Paint: Properties built before 1960 may contain lead paint. Professionals must follow specific safety protocols (HSE guidelines) for removal and disposal.

Common Problems

• Poor Surface Prep: Paint peeling or flaking within months usually indicates the surface wasn't cleaned or sanded properly.
• "Ropiness": Visible brush marks or roller textures caused by using cheap tools or applying paint too thickly in warm weather.
• Bleed-through: Stains from water damage or knots in wood appearing through the topcoat because a specialist primer wasn't used.
• Flashing: Uneven patches of sheen caused by failing to maintain a "wet edge" during application.

Frequently Asked Questions

Do I need to buy the paint myself?

Most professionals prefer to supply the paint as they can access high-quality trade versions of brands like Dulux, Crown, or Farrow & Ball. Trade paint often has higher pigment levels than the retail versions found in DIY sheds.

Can painters work in the winter?

Internal painting is fine year-round, provided the room is ventilated. External painting is usually restricted to April through October in the UK, as masonry paint requires temperatures above 5°C and dry conditions to cure properly.

How long should I wait before moving furniture back?

While paint may feel dry to the touch in 2–4 hours, it can take up to 7 days to fully "cure" or harden. Avoid pushing furniture flush against walls for at least 24–48 hours to prevent sticking.

Is wallpapering more expensive than painting?

Generally, yes. Wallpapering requires more precision, specialist adhesive, and often more intensive wall preparation. The cost of the rolls themselves can also significantly increase the project budget compared to a tin of emulsion.

What is the difference between Trade and Retail paint?

Trade paint is formulated for professional use; it is usually more concentrated, offers better "opacity" (coverage), and is designed to be thinned slightly if needed. Retail paint is often pre-thinned for easier DIY application but may require more coats.
