Hi guys.... many thanks for the info The blow-up bags sound like a good idea ! I intend replacing the door-frame completely - screw 'n glue into the masonry Then put the required packing the full length of the frame - get it 'true' - screw 'n glue Screws - will go for the Torx .... how much of the screw should be into the masonry ? .... rough guide ? .... educated guess ? What's your favourite sealant ? Thanks again for the help .... Peter

Hi Everyone ! First post .... I'm Peter - a retired Merchant Navy IT/Electronics/Electrical Engineer. Finally getting round to jobs on a French house we've had for years, but only got there really for short holidays. I've done a lot of DIY back home but never fitted a upvc door.... and the more I read the more complex it seems to get ! The really old wooden back door has rotted .... and found rot at the bottom of the frame also. The existing door is 930mm, entrance (from garden/patio) is 900mm. Door-frame is 70x50mm with 15x35mm rebate. The new upvc door (local - diy store "Leroy Merlin") is 850mm wide - 860mm with 'space'. (900mm would mean cutting into stonework door-frame) The entrance-way is 350mm deep so not fitting sill.... water came in through a damaged down-pipe and a crack in the porch floor. Questions: 1) As the new door is pre-hung will it still require the heel-and-toe routine ? 2) The new frame will need 35mm packing each side. Do the shims go between the masonry and the packing or between the packing and the upvc ? 3) The door is 70mm deep. An 8mm fixing screw at 35mm would be about 5mm away from the join between the wooden frame and the masonry. Would it be better to just set the door back a bit to be away from this join ? What sort of distance from the join ? 4 I intend using 120 x 8mm - these have the top section threaded for the plastic and the bottom section standard spiral thread. The manufacturers recommend using a 5.5mm SDS if going directly into the masonry, or 8mm if using the standard 'Rawlplug' insert piece. Any thoughts on this ? 5) With the door being a single double-glazed panel, could vibration from an SDS drill possibly cause cracking of the glass ? 6) What's the recommended sealant for upvc ....I know there is a forum for this, but hope someone who's "been there, seen it, done it" will post here. Any and all comments will be greatly appreciated. Cheers Peter
