Can't believe that someone told you one color would last longer then another. Must not be a very experienced salesperson.

Next time, if you go back to Lowes, ask for the Cabot oil based sealer. Doesn't matter what color.

Good Luck

I don't know why a contractor wouldn't want to pull a permit to protect their license. It is not a big deal and they will obviously charge you for it anyway.

Good luck

First, as Woodbridge and Dan have stated, check to see if it is allowed in your area and if neccessary, approved by your HOA.

Then, depending on the existing structure, ie: if the roof structure is the same as the house with trusses and headers with piles properly placed on footers, as opposed to a lean to type roof, (as Woodbridge said), then, not sure about GA, but down here in my area the price would vary from $81.00 to $122.00 a square foot depending on windows, doors and electrical work desired, as well as type of brick you are trying to match.

This would be a simple unfinished interior garage, no insulation or drywall.

You also need to double check for any power and gas meters which are sometimes placed in or near carport areas. They may have to be moved which will add to the expense.

Good Luck
