Stud wall cost: what goes into building a partition wall

Stud wall cost factors

Size is the obvious starting point, but it is rarely the biggest variable. What sits around the wall matters just as much: an uneven floor, a sloping or sagging ceiling, or a wall that has to meet a window reveal or a radiator all add cutting and fitting time.

• Length and height of the wall
• Whether a door opening and lining are needed
• Insulation for sound or warmth
• Boarding, taping, skimming and decoration
• Moving or adding electrics, which needs an electrician
• Making good floors, ceilings and skirting where the wall meets them

Timber or metal studs

Timber studs are the traditional choice for houses and are easy to fix into later, which helps when shelves, radiators or a TV are going on the wall. Timber can twist slightly as it dries, so straight, well seasoned lengths make a difference to the finish.

Metal studs are light, perfectly straight and do not move, which is why they are common in commercial fit outs and on long, tall walls. They need specific fixings for anything heavy and a bit more planning where items will hang. For most domestic partitions, timber is the practical choice.

Door openings and linings

A door in the wall means a properly sized opening with a header above it, a door lining fitted plumb and square, and then the door, hinges, handles and architrave. That turns a straightforward partition into a small carpentry job of its own. The cost to hang a door guide and the door fitting page explain what goes into that part.

Choosing the door before the wall is built is worth doing, so the opening can be framed to suit it rather than trimming the door to fit afterwards.

Insulation and sound

An empty stud wall carries sound well, so a partition between a bedroom and a living space can feel thin. Filling the cavity with acoustic insulation, using denser board and sealing the edges where the wall meets the floor and ceiling all reduce noise noticeably. Two layers of board on each side go further again. Each step adds material and time, which is why it is worth deciding early how quiet the wall needs to be.

Boarding, skim and decoration

Once the frame is up, plasterboard is fixed to both sides. From there the finish can stop at taped and filled joints, ready for decoration, or go to a full skim coat of plaster for a smoother wall. New plaster needs to dry before it is painted, so decoration is often a separate stage a short while later.

If the wall will carry shelves, a TV bracket or kitchen units, extra timber noggins are built into the frame at the right height before the board goes on. That is far easier than adding fixings later, and the hanging shelves on plasterboard guide and the TV mounting page explain why it matters.

Electrics in a new wall: a job for an electrician

Sockets, switches and light fittings in a new wall need a qualified electrician. The usual order is that the frame goes up, the electrician runs cables through it, and then the wall is boarded, with the electrician returning to fit the faceplates at the end. Planning that order at the start avoids boarding a wall and then cutting it open again.

Building a stud wall is part of the carpentry and general building work CRF Services Ltd takes on around Rochester and Medway. Where a job needs another trade, such as an electrician, Danny will say so at the quotation stage.
