Where’s the job?

Scope of Works

• Inspect existing external door, frame, threshold and reveal and take accurate measurements

• remove existing door leaf, hardware and trims and dispose if agreed

• prepare or replace timber or uPVC frame, make good opening and ensure structural fixings where required

• fit new external door or prehung unit, adjust for plumb, level and correct operation

• install locks, hinges, draught seals, threshold and any flashing to weatherproof the opening

• seal and finish internal and external trims, test locks and operation, and tidy site

• use appropriate PPE and dust containment when cutting frames or removing old materials

Typical Cost

Time on Site

Typically 3–6 hours for a straight swap of a prehung door; 1–2 days when replacing the frame or carrying out minor brick or plaster repairs. Lead time for bespoke doors (1–6 weeks) and the need for scaffold, additional trades (plasterer, bricklayer) or discovering rotten timber can extend total project time

Questions to Ask Your Tradie

• do you supply the door and hardware or is that extra

• is the multipoint lock insurance‑approved and what warranty do you offer on supply and labour

• will you replace the frame/threshold if needed and is that included in the fixed price

• who is responsible for making good plaster, trims or external pointing and do you use subcontractors

• what is the lead time for the door and are provisional sums included for delays

• are scaffold, permits and disposal included or quoted separately

How to Avoid Surprises

• ensure clear access to the door, remove ornaments and roll up rugs and reserve nearby parking for the fitter's van

• agree in writing who orders materials, where they are delivered and who signs for them

• check whether frame replacement, pointing or plastering is included and plan for additional trades if not

• tell the tradie about alarms, pets and neighbours who may be affected by noisy work

• check whether planning, party wall or building control approval is needed for structural changes
