Handyman Job in St. Thomas, Ontario

I'm replacing an antique 24" dishwasher with a new one which is 23.5" wide and about 2" lower at the moment. The space is too large. Good quality hardwood needs to be drilled into the cabinetry sides, top and bottom so the dishwasher has something to screw into - and stay screwed into. The woodwork needs to be good enough that it blends reasonably seamlessly with the surrounding cabinetry. The new dishwasher needs to be levelled before the wood can be measured. I also have a new fridge that needs levelling. The instructions look complicated.
