I'll try to keep this short. Our driveway and sidewalks, 20+ years after building our house, have dropped quite a bit. The step up from the sidewalk to the porch is now 12 inches. It was 8 when we built the house. The driveway hasn't dropped that much, but the bump pulling into the garage is noticeable, plus the gap between the garage slab and the driveway has widened to over 2". I want to fix the sidewalk and the driveway. Options: 1. Concrete raising. Pros: Cheapest option, by far. $1500. Cons: Won't fix the 2" gap between garage slab and driveway and we would need to fill it. There is a crack the width of the sidewalk that the raising guy says will probably get bigger and have to be caulked. Jacking it pokes holes in the slab that they fill. Between the holes, the caulk, and filling the crack with (?) something, this sounds like I will have frankensteined flatwork. 2. Replace the entire sidewalk, and only the driveway slabs that connect to the garage. Pros: Will fix the gap between garage and driveway. No punched and filled holes in the slab. Sidewalk won't have that crack anymore. Cons: Old and new driveway would be different colors, cost $4500. 3. Replace the entire sidewalk and driveway. Pros: Fixes all issues listed above. Would look the best, which is not a small consideration for me. Cons: Cost is $7200. Okay, collective brain. What do you think? Any experience with this type of repair? Thanks.
