Comparing 2 quotes for a new patio and a piece of driveway we need replaced, I am having trouble deciphering who to choose. They are both the same price but one person is giving me more for my money I think. His quote included 5" thick, excavate, gravel, compact, 6" bag, low chert,hand tool control joints, 10 gage wire mesh and fiber mesh,expansion felt, sealing compound,back fill and grass seed. We live in the midwest where the winter is bad. Is 5" thickness necessary, and why two different kinds of mesh? Is it normal for a contractor to ask for 200 when signing the contract? I have had them both ask for a deposit upon signing of the contract. The other contractor was only quoting 4" thick? Any suggestions??
