Every block of flats needs its outside redecorated on a regular cycle. Many leases set this at every five to seven years, and for good reason. Paint, render and timber are the first line of defence against the weather. Leave them too long and a straightforward redecoration turns into repairs that cost far more.

This guide explains how an external redecoration project works for a London block, what is usually included, and how to keep it on time and on budget.

What external redecoration usually covers

The exact scope depends on the building, but a typical specification includes:

• Preparing and painting render, stucco and masonry paint finishes
• Repairing and repainting timber and sash windows, doors, fascias and soffits
• Painting metal railings, balconies and fire escapes, after treating any rust
• Clearing and repairing gutters, downpipes and hoppers
• Small masonry and render repairs found once the scaffolding is up
• Sealant renewal around windows and doors

On period buildings in areas like Maida Vale, Kensington and Chelsea, the finish matters as much as the protection. Stucco fronts and original sash windows need the right materials and a careful hand, not a quick coat of paint.

Step 1: Survey and specification

Good projects start with a proper look at the building. A survey records the condition of every elevation and sets out exactly what work is needed. That becomes the specification contractors price against, so every quote compares like for like. Our guide on why a building survey should come before major works goes into more detail.

Step 2: Section 20 consultation

If the work will cost any one leaseholder more than £250, the landlord or managing agent has to consult leaseholders under Section 20 of the Landlord and Tenant Act 1985 before the work goes ahead. This involves formal notices and time for leaseholders to comment and nominate contractors. Build this into the timeline from the start. Skipping it can limit how much of the cost can be recovered through the service charge.

Step 3: Timing and weather

Most exterior paints need dry weather and temperatures above a set minimum to cure properly, so the main painting season runs from spring to early autumn. Planning the consultation over winter means work can start as soon as the weather allows, instead of the project slipping into the following year.

Step 4: Access and scaffolding

For most blocks, scaffolding is the biggest single cost after labour. It is worth doing everything that needs high-level access in the same visit, including roof, gutter and window repairs. Bringing scaffolding back later for a missed job costs far more than including it at the start.

Step 5: Keeping residents on side

Residents live with the works for weeks, so clear communication makes a big difference. Let them know the start date, which elevations are being worked on and when, and when windows need to be kept closed. A named contact for questions keeps complaints down and the job moving.

Step 6: Snagging and handover

Before the scaffolding comes down, every elevation should be checked against the specification and any snags put right. Once it is gone, fixing a missed area means paying for access all over again.
