Fit a roller blind inside the window recess in a metal stud wall

Fit a recess roller blind safely, checking wall type, cables and pipes, then fixing brackets correctly for a secure finish.

RB-01Measure the recess and gather your kitMeasure the width of the window recess at the top, middle and bottom, and take the smallest figure so the blind fits inside without binding. Measure the depth too — you need at least 30-40mm of clear depth for most roller cassettes. Buy or cut your blind to this size, and lay out your tools before you start.

RB-02Work out what's behind the revealWindow recesses are lined differently depending on the build. Run a stud detector or magnet up and down the side or top of the reveal — a regular line of screw heads under the surface, spaced roughly 300-600mm apart, means a lined stud wall rather than solid masonry. Drill a small 3mm test hole in an inconspicuous spot: fine pale dust means timber, grey powder usually means plasterboard over a dot-and-dab wall, and bright metallic swarf means a metal stud frame. If the recess sounds solid and dense when you tap it, and dust is grey and gritty, you're into brick or block.

RB-03Check for cables and pipes before you drillCables and pipes can run almost anywhere, including up and around a window opening to a nearby socket or light switch. A detector helps, but it can miss cables that are deep, in metal conduit, or behind metal-backed plasterboard, and a metal stud frame will confuse a cheap detector further — so always expect something could be there and drill carefully. Find your stopcock, usually under the kitchen sink, and check it turns before you start. If you have any doubt at all, isolate the relevant circuit at the consumer unit before drilling.

RB-04Mark and level the bracket positionsHold the top bracket in position inside the recess and mark the screw holes with a pencil. Use a spirit level to check it's dead level before marking the second bracket at the other side, at the same height. Double-check the gap between brackets matches your blind's cassette length before drilling anything.

RB-05Drill and fix the brackets for your wall typeIn solid brick or block, drill 6mm holes to 40mm deep, insert plastic wall plugs, and drive in the bracket screws. In a timber stud reveal, screw a 4x40mm wood screw straight into the centre of the timber upright — no plug needed. In a metal stud reveal, use a self-drilling metal-stud fixing or a screw-and-toggle rated for 0.5mm steel; never use a plastic plug or an ordinary wood screw, as they strip straight through. On dot-and-dab plasterboard over masonry, use a fixing long enough to pass through the plasterboard and adhesive dabs into solid masonry behind — typically 60-75mm. On lath and plaster, aim for a lath if you can find one, or use a spring toggle sized for the blind's weight, since the old lime plaster crumbles under ordinary plugs. A roller blind is light, so a correctly rated hollow-wall fixing is normally enough — only add a timber noggin or pattress behind metal studs or plasterboard if the recess is very wide or the blind unusually heavy.

RB-06Fit the blind cassette onto the bracketsClip or slot the roller blind cassette into the fixed brackets, following the manufacturer's instructions — most simply push and click into place. Check both ends are seated fully before letting go. Give the cassette a gentle pull to confirm it's secure.

RB-07Fit the chain safety deviceAttach the chain or cord safety cleat to the reveal at the height supplied with the kit, keeping the chain tensioned and out of reach when not in use. UK-sold blinds must include a child-safety device on the chain or cord under BS EN 13120, and fitting it correctly matters most where children could be present.

KNOW THE RULES

Corded and chain-operated blinds sold in the UK must include a safety device to reduce the risk of child strangulation, under BS EN 13120. Always fit and use the device supplied.

RB-08Test the operation and adjustPull the chain to lower and raise the blind fully, checking it runs straight and doesn't rub the sides of the recess. If it hangs skewed, loosen one bracket slightly and re-level before retightening. Check the fabric sits flat against the window when fully lowered.

RB-09Clear upVacuum any drilling dust from the sill and floor, and wipe down the recess. Bag up offcuts and packaging, and store any spare fixings for future use.
