Hi all. I will be replacing a patio for my mother. Right now, she has a raised brick patio with a concrete slab (about 3ft high and its 10x12) attached to back of house w/doorwall leading out. Its in bad shape, leans toward house and we are afraid it was built without properly sealing a basement window that is behind it because water gets in sometimes, so it has to come down. She can't seem to decide what to replace it with...another of the same, or something else..(Both cost and upkeep are main considerations) Here are the options with questions I have...we live in Michigan, so cold winters need to be factored in. A ground level slab of concrete (does stamping concrete weaken it and tend to crack sooner? Does staining require upkeep?) Pavers (do they tend to shift or raise even when done right with gravel/sand under?) A composite wood look patio (Open to any other suggestions) Please let me know...Which would be the cheapest option for materials? (without including cost of professional labor) Thanks so much!
