Cost property maintenance.

Engaging a professional builder for a "snagging" or maintenance visit ensures that minor issues—such as failing mortar, cracked plaster, or blocked drainage—are addressed before they escalate into high-cost structural repairs. This guide outlines the typical costs and considerations for general building maintenance in 2025/26.

What Does the Work Involve?

• Site Assessment: A thorough walk-through to identify structural snags, damp issues, and external masonry wear.
• External Repairs: Repointing brickwork, replacing damaged air bricks, clearing guttering, and checking roof tiles or flashing.
• Internal Remediation: Patching blown plaster, repairing ceiling damage from historical leaks, and addressing settlement cracks.
• Structural Integrity: Checking lintels, joists, and floorboards for signs of rot, infestation, or movement.
• Damp Prevention: Ensuring damp proof courses (DPC) are not bridged and that external ground levels are correct.
• Waste Management: Clearing debris and ensuring the site is safe and tidy following masonry or plastering work.

Typical Costs

Prices are inclusive of VAT and reflect 2025 market averages. Costs fluctuate based on property height (scaffolding requirements), the age of the building (period properties often require specialist lime-based materials), and regional labour shortages.

How Long Does It Take?

• Minor Snagging: 4–8 hours for a list of small repairs like loose floorboards or minor plaster cracks.
• External Maintenance: 1–3 days for gutter clearing, localized repointing, and checking roof seals.
• Internal Refurbishment: 3–5 days for significant plastering, damp treatment, or chimney breast repairs.
• Emergency Repairs: Usually resolved within 2–4 hours, focusing on making the property safe or watertight.

DIY or Professional?

While basic tasks like painting or clearing low-level gutters are suitable for DIY, structural maintenance requires a professional builder. Incorrectly "fixing" a damp issue or using the wrong mortar type can cause permanent damage to your brickwork and trap moisture within the walls.

Always hire a professional for work involving structural walls, chimney stacks, or anything that requires working at height over two storeys.

Note that any electrical work must comply with Part P of the Building Regulations, and gas-related maintenance must be performed by a Gas Safe registered engineer. Builders often manage these sub-contractors for you as part of a larger maintenance contract.

Choosing the Right Tradesperson

• Check Accreditations: Look for membership in the Federation of Master Builders (FMB) or TrustMark status.
• Verify Insurance: Ensure they have Public Liability Insurance (minimum £2 million) to cover accidental damage to your property.
• Review Portfolios: Ask for photos of previous "before and after" repair work, particularly for masonry or plastering.
• Questions to Ask:
  • Are materials included in the quote or charged at cost?
  • How do you handle the discovery of hidden issues, such as dry rot?
  • Will you provide a written guarantee for the repairs?
  • Is waste disposal included in the price?

UK Regulations

• Building Regulations: Most minor repairs are "exempt," but structural changes (like removing a wall) or replacing windows require Building Control sign-off.
• Listed Buildings: If your property is listed, you must obtain Listed Building Consent before any repairs that change the appearance or use non-original materials.
• Part L: Repairs to more than 50% of a thermal element (like a wall or roof) may require you to upgrade the insulation to meet current standards.
• Waste Duty of Care: Builders must hold a waste carrier's licence to remove rubble from your site legally.

Common Problems

• Mismatched Materials: Using modern cement on old bricks can cause the brick faces to "spall" or explode during a freeze.
• Ignoring the Root Cause: Patching a damp ceiling without fixing the slipped tile above is a waste of money.
• Poor Access Planning: Failure to mention difficult access or the need for scaffolding can lead to sudden price hikes on day one.
• Inadequate Drying Time: Rushing to paint over new plaster before it has fully cured leads to peeling and bubbling.
