I've done more than a little DIY in my time, 2 bathrooms, 2 kitchens, laminate flooring etc etc. but it's good to get a tradesman in if you can afford it.Unfortunately if you can do something yourself it's difficult to justifying paying someone else in my eyes. Only if I've not got the time will I pay someone..
I paid someone to fit my front bay windows double glazing as they were a ball ache. Everything else I can do. Plumbing, electrics, fitted kitchen and bathrooms. Raised all the doors heights. New frames and doors etc. It makes upgrades or repairs to the house a lot cheaper.. plus I think I do a better job a lot of the time!
