Where’s the job?

Scope of Works

• Survey the window reveal, check studs and ensure the opening suits the proposed seat

• remove existing sill/trim and make good plaster where needed

• build and fix a timber or MDF carcass to wall or studs and provide internal framing for storage

• fit seat top, hinges or drawer runners and any upholstery or paint finish as agreed

• protect floors and windows, use PPE and contain dust when cutting or removing old materials

• clear site, remove scrap and touch up surrounding plaster and paint as part of handover

Typical Cost

Time on Site

Simple fitted window seats with storage typically take 1–2 days on site; a basic standalone seat can be fitted in 3–4 hours. Factors that extend time include bespoke joinery, structural alterations, plastering and drying time, scaffold or restricted access

Questions to Ask Your Tradie

• can you show examples or photos of similar window seats you have installed

• will the seat be fixed to existing studs or require new framing

• do you anticipate any structural or building‑regulations work for wider spans

• what materials and finishes are included, and what would be extra

• who does the plastering and redecorating and is drying time included in the programme

• how will you protect floors and windows and manage dust and lead‑paint risks in older properties

How to Avoid Surprises

• confirm access and parking for the van and where materials can be stored

• clear the work area of curtains, plants and soft furnishings before the trade arrives

• check building or freeholder rules and get permissions for structural changes in flats or listed buildings

• agree disposal arrangements and any extra costs for rot, mould or unexpected repairs

• ensure power is available for tools or agree to provide a generator if needed

• let the tradie know about pets, fragile items and any lead‑paint or asbestos concerns before work starts
