Dry Lining & Plasterboarding

Dot & dab or stud wall: what's the right way to build it?

Dot and dab is for lining an existing solid wall: boards bonded to the masonry with adhesive dabs, adding only 15–40mm of depth. A stud wall is for creating a wall where none exists — a timber or metal frame, boarded both sides, dividing one space into two.

They solve different problems, so the choice is usually made for you. Lining a lumpy or cold external wall, hiding chased-in cables, or covering sound-but-ugly masonry: dot and dab, every time, and done properly it is quick — a room lined in a day. Dividing a bedroom, building a loft en-suite, boxing a utility space: that is a partition, and we favour metal stud systems for most of them — dead straight out of the box, no timber shrinkage cracks at the joints later, and voids ready for insulation and services. Timber studs still earn their keep where heavy fixings or door frames demand them.

One scope note so expectations are straight: partitions are the walls themselves — where a new room needs power, lighting or waste runs, those trades slot in after first fix, and we coordinate happily with yours. Our job is that the wall is straight, solid, quiet and finished ready to decorate — and where the project includes new floors too, our floor screeding service covers the horizontal half of the job, including over underfloor heating pipes.

Tape & joint or skim finish: which should you choose?

Tape and joint finishes only the board joints and screw heads, leaving the board surface as the wall — faster, cheaper and ready to decorate sooner. A skim finish coats every inch in 2–3mm of plaster for a harder, flatter, more forgiving surface. Skim costs more; it is usually worth it in homes.

Tape and joint, done to a proper standard with feathered joints sanded flat, is the default across commercial fit-outs for good reason: it is quick, dry and consistent, and under flat matt paint it looks clean. Its weakness is raking light — low sun or wall washers can pick out the joint lines on a long wall — and the paper face of the board is less tolerant of knocks, fixings and future redecorating than plaster.

A full plaster skim over the boards gives the wall one continuous, dense surface: flatter under any light, tougher against family life, and the finish most decorators prefer to paint. Our honest steer: tape and joint for garages, utility spaces, offices and rental refreshes; skim for the living spaces of your own home. We price both on every dry lining quote so the choice is yours with the numbers in front of you.

Which plasterboard does each room need?

Standard Gyproc board suits most dry rooms. Bathrooms and kitchens need moisture-resistant (green) board. Party walls, bedrooms and home offices benefit from acoustic board. Integral garages, plant cupboards and escape routes may need fire-rated (pink) board, and cold external walls can take insulated-backed board.

Moisture board is the one that gets skipped most and regretted fastest: standard plasterboard wicks water, softens and blows its paper face in humid rooms, while the green boards carry water-repellent additives in the core — still needing tanking behind showers, but the right canvas everywhere else in a bathroom or kitchen. Acoustic boards are denser, and paired with mineral wool in the stud void they turn a flimsy partition into a wall you cannot hear a television through — the difference between a loft bedroom and a loft echo chamber.

Fire-rated boards buy defined minutes of fire resistance and are required by Building Regulations in specific places — between an integral garage and the house, under stairs on escape routes, and in much commercial work, where fire strategy drawings dictate board spec, layer count and even screw centres. Insulated boards — plasterboard factory-bonded to foam insulation — are the pragmatic upgrade when dot and dabbing the cold external walls of an older solid-wall house. We spec the board per room on the quote, and we put the spec in writing, because "it's all just plasterboard" is how bathrooms fail.

What does dry lining cost in 2026?

As a working guide for 2026: dot and dab lining runs per board with room prices typically £350–£700 depending on wall area and board spec; a straightforward stud partition, boarded both sides and finished, from around £450; tape and joint finishing is cheaper than skim by roughly a third.

The variables that move a quote are board specification — moisture, acoustic, fire-rated and insulated boards all cost more than standard — insulation in the void, the number of openings (a doorway means a frame, a lintel detail and more cutting), and the finish you choose. Ceilings price higher per square metre than walls because overhead boarding is slower, two-person work; boarding over a tired existing ceiling and skimming typically runs £350–£600 a room.

We quote fixed and itemised: boards, studs, insulation, finish and making-good as separate lines, so you can see exactly what adding acoustic board to the bedroom wall or upgrading the finish from tape and joint to skim actually costs. Small jobs are welcome — a single lined wall or one partition is a normal day's booking, not a nuisance — and for larger fit-outs we price per square metre with the rates shown, so extending the scope mid-project carries no mystery.
