A new surface needs a suitable background
Quick answer
Internal plastering can involve rebuilding a base, finishing an existing surface or completing newly lined walls. Those are different jobs. Tell the plasterer whether the room has bare masonry, painted plaster, patches or new boards, and explain the finish you want. A smooth top layer cannot make an unstable background sound. Agree what is retained, repaired and replaced before comparing prices. This helps avoid a quotation for a finish when the room actually needs preparation and base work.
Base work, skimming and making good
A full wall build-up and a thin finish coat have different preparation and material needs. The professional should assess the background and specify compatible layers rather than describe every job simply as plastering. British Gypsum publishes product-specific system guidance; it is one technical reference, not our recommended supplier. Clarify whether chases, corners, window reveals and transitions to retained surfaces are included. If another trade is still changing the room, agree the sequence so newly finished work is not immediately cut open.

Damp or failed plaster comes first
Staining, repeated bubbling and loose finishes need a cause assessment before cosmetic work. Water ingress, a plumbing leak and other moisture problems can require different help. Explain the history and any earlier repairs without treating a photograph as a diagnosis. Do not ask for damp to be sealed behind a new finish without a considered plan. If the wall is unsafe or material is falling, keep people clear and obtain direct appropriate help. Skimming is not an emergency response to an unresolved leak.

Traditional materials in Sudbury
Babergh’s September 2024 guidance addresses historic renders and plasters. For an older or listed Sudbury property, establish what fabric is present and whether the proposed change affects its significance. Historic England also advises compatible repairs and addressing moisture causes. Age alone does not identify the wall construction. Ask for a reasoned material proposal, and check any consent requirement for the actual work before removing historic finishes.

Working in an occupied room
What to tell the plasterer
Discuss access, furniture protection, dust control, waste removal and which parts of the room remain usable. Identify sockets, plumbing and other fittings that need separate qualified attention; the plastering price does not automatically include their removal and reconnection. Agree protection for retained floors and joinery. A room-wide finish can require different access from a small patch. If there are suspected hazardous materials, have assessment and the safe work scope resolved before disturbance rather than leave this to the day work starts.
- Room size, background and the intended finish.
- Leaks, loose areas and previous repairs.
- Access limits, retained fittings and any property restrictions.
Compare complete plastering quotes
Ask for measured areas, preparation, base work, finish, beads and corners, protection, waste and VAT. Define decoration and work by other trades separately. A low finish-only price and a full room repair are not comparable. State how concealed problems will be reported and revised costs approved. If the quotation relies on an existing background being sound, make that assumption visible and agree what happens if inspection shows otherwise.
| Work | What to clarify |
|---|---|
| Skimming | Preparation and suitability of the retained background. |
| Base and finish | Extent of rebuilding and compatible layers. |
| Making good | Which chases, reveals and adjoining finishes are included. |
Drying, decoration and handover
Ask for aftercare appropriate to the chosen materials and conditions, including when decoration can begin. There is no reliable fixed drying time for every room and thickness. Agree the inspection and finish expectations before work, including corners and transitions. Keep the specification, invoice and any care information. For an enquiry, provide postcode, approximate room/area and the main concern. We review local requests and may help connect suitable businesses; sending details does not book an appointment or guarantee attendance.
