The patio door in my Dad's living room has had it. The wood on the sliding door is buckled, and now the glass is broken. Dad has dementia and I need to arrange to have it replaced.vHe lives with my bother who has managed to shut the door to. Bro has mental health problems and just would never have the resources to manage he situation.it falls on me to get this sorted and I don t know where to start. Who do I go to? A carpenter? A double glazing company? I have no idea who put the door in originally and will probably never know as Dad won t be able t tell me.thanks for any advice.
