Is the problem ...
The stair string has split ?
Unless the timber is a hardwood you wish to leave exposed, you can fill small cracks before you re-decorate under householder maintenance.
There is a gap between the stair string and the wall ?
Unless the gap is greater than 4mm you can fill small cracks before you re-decorate under householder maintenance, otherwise report it as a defect.
If you have just moved in, here are some important reminders:
Don't forget to complete all of the warranty cards for your fitted electrical appliances. Keep a copy and send them off to the manufacturer. Should you ever need to report a fault, you know they will have proof of your cover.
Make a note in your diary to book a service in 12 months time. Failure to maintain annual services could invalidate your warranty cover.
WATER AND GAS SHUT-OFF VALVE
Make sure you (and other responsible members of the household) know where to find the shut-off valves for water supply and (if applicable) gas.
Make a note of your meter readings for your electricity supply, water and gas (if applicable). Keep it somewhere safe.
