What makes stairs squeak? The noise often comes from free treads (the floor of the steps that you just stroll on) or risers (upright boards that be a part of the treads collectively). That is usually as a result of pure shrinkage of the picket stair parts over time. The adhesive that was initially used to bind the risers and treads collectively may additionally have failed.There are a number of strategies of tightening up the steps to cut back or eradicate the creaking. One of the best ways is to work from beneath the staircase, because the outcomes will not present and you may often make a stronger restore. If this isn’t attainable you’ll have to sort out the issue from the opposite facet.Repairing squeaky stairs from aboveThere are three foremost strategies of tightening up free stair elements:1. Screw the treads downThe greatest means of fastening the treads securely to the risers is by screwing them down. Three screws per tread is often sufficient. Drill pilot holes by the tread in step with the riser, ideally utilizing No.eight x 38mm countersunk screws, then drive within the screws under the floor of the tread. If there isn’t any stair carpet to cover blemishes, conceal the screws with matching wooden filler.
2. Nail down free treadsA easy restore is to hammer nails into the sting of the tread at a central level the place it connects with the riser. For the very best grip, insert the nails in pairs in order that they’re angled in the direction of one another over the creaky spot. Drill pilot holes first to keep away from splitting the wooden, then drive the nails under the floor and canopy with wooden filler.three. Glue on a mouldingTry including a chunk of quadrant moulding (formed to type 1 / 4 circle) to offer the tread additional help. You’ll be able to safe it to the highest or backside of the riser, or each. For the very best outcomes, stick the moulding to each the tread and the riser.

Place a block in every nook of the step underneath the tread and in opposition to the riser, and glue into place. Safe with screws – drive two upwards, into the tread, and two horizontally, into the riser. If attainable, get a helper to face on the tread whilst you drive within the screws.
Alternatively you possibly can safe small rectangular blocks of wooden, often called string blocks, to the corners of the steps to lock the treads to the strings (supporting boards that run alongside the facet of the steps). If vital, you need to use these along with the glue blocks for additional energy and rigidity.2. Exchange wedgesMake positive that the picket wedges – that are used to lock the stair treads and risers into their matching slots – have not fallen out or begun to slide. Exchange any lacking or broken wedges and glue free ones again into place earlier than tapping them firmly dwelling with a mallet.Small ‘slip’ wedges, or shims, are one other efficient means of tightening the joints between risers and treads. The wedges ought to be round 30mm lengthy and 3mm thick, tapering down to some extent. Glue into place, then use a pointy chisel to shave off any protruding ends.
