hey guys, this is my first post. im hoping i can get some help on a job im about to undertake for my nanna.

im pretty handy but dont know much about timber.

she needs a door replaced and the frame, one wall board and skirting, as well as about 16 hardwood floorboards.
the whole area faces south and has no eaves or protection from weather. as a result it is all rotten but its taken about 30-40 years. its a really old house and i also suspect that the stud closest to the door is rotten out down the bottom too, behind the wallboard (thin ply)

anyways im going to replace it all and want to know what kind of materials and finishes i should use. the cheaper the better, 2nd hand is an option. need it to last 20 years any more is a bonus. I've seen some good solid (heavy) 2nd hand doors around cheap. same goes for the flooring. my main question is in regards to the door frame timber, reveal i think its called? hardwood, pine, mdf? i have no idea. will the stuff at bunnings be sufficient? it will all ideally be painted.

any help would be great thanks.

Treated pine is the way to go if you're painting it.

MDF won't last if it is exposed to weather. Treated pine or hardwood would be the best. Pine is cheaper.

Be aware that you need to wear a particulate dust mask (or better, a respirator) with treated pine when doing any sanding/sawing activities, and don't fireplace the scraps.

Also be aware that you will need to flash the door frame during installation.

You don't make any mention of the condition of the sill? Even if it is in good nick (I'm guessing it'd be made from Kapur, Ironbark or similar, given the house age & 'historical' sill timbers) then you still want to pull it out as well, to check the frame condition.

Personally I'd go for a naturally oily hardwood. Jarrah, perhaps. Costs more, :( but once sealed & painted it'd last another half century with minimal maintenance.
