Re-laying wood floor with fitted wardrobes

You would be able to use a oscillating multi tool with good blade(s) to cut trees flooring along the front of the wardrobe. Remove the flooring piling it up in order of the rows you take out (assuming it’s not been glued together). Make sure the subfloor is creak free and the. Replace the flooring using wood glue along the tongue and groove. Leave a small expansion gap (along the wardrobe and cover with flat strip to hide the cut edges and gap).

A decent fitter would obviously use a multi tool to cut around the wardrobe. Then lift and mark each row for when it goes back down. But heres the but!! Most fitters will fully stick and engineered floor not float it . But you need to check your sub floor for this , if your subfloor is chipboard then you would have to overlay it with 6 or 9mm ply gluing it to the subfloor Then screwing it at 100mm centres Relaying of floor could then commence , applying enough glue to lay 3-4 rows at a time using straps to pull it together so no joints pull apart Allow 10mm expansion gap around peremiter

Hi if is a fitter walldrop cut round the wall drop and laying rest of the room

Its more likely that the sub floor is causing the noise. Lift and number the engineered flooring as described by previous tradesman. Then the sub floor may have to be renewed or repaired. A Good quality underlay could also help with noises.
