Gap around new UPVC door and frame & condensation on new windows.

I take it the front door is a composite? If so their should be a maximum of 4mm between slab and frame, To allow the door to operate correctly and still be draught sealed. Condensation on the windows is more to do with humidity in the house, trickle vents would help but not eliminate it. Look for the cause of the high humidity and try to reduce it. Bathrooms & kitchens must have external mechanical ventilation. Even humans exhale about a liter of moisture each night. Hope this helps

Hello there, the door might be over tightened so it could be bowed, when shut you shouldn't see any day light coming in, and trickle vents should be fitted as standard.hope this helps

firstly check that under door as been foamed and bedded on cill ,then check sides have been foamed and sealed. the condensation in new windows is normal and will happen for short while,i would think your glass is k glass/coated if windows are new this happens with new units the k/coated glass keeps cold out and heat in during winter and vice versa in summer the problem with this when warm and cold meet the result is condensation. condensation can also be caused by heaters being on under the window ,people drying clothes on heaters etc but condensation does occur in winter the vents are to allow air to circulate in the room but again if its warm in room and your letting cold it could result in condensation . do you have mould in bottom corners off windows or black spot on insides if so your windows may not be bedded down or back sealed hope this helps
