Hi my house is 18 months old bought as new build. Big mistake
Anyway front door is leaking and I noticed huge gaps in external sealant round windows and on door frames
The builder has been back and resealed windows said gaps were due to settlement
Got talking to neighbours today and found out at least 3 of us have... leaking front doors
Clearly some wider issue so can I argue for replacement door? Also is it normal to have to have windows resealed?
