You're not alone. I've had my share of water issues this year too and man does it suck...this winter when things warmed up at one point in Feb our basement flooded because of a crack in the foundation. My daycare was down there and we had just finished the flooring the year before and it had to be ripped up. But I ended up moving the daycare upstairs and I actually prefer it that way now. We never replaced the flooring down there and instead I painted the concrete and added area rugs for warmth and we use it as an extra family room/ daycare nap room. Then this weekend we turned the hose on outside, hubby comes downstairs to do laundry and there is water everywhere. Turns out we left the hose connected (although the valves had been shut off) throughout the winter and the pipe cracked. We left the hose on 5-10 mins. I don't even want to think about how bad it could have been had we left it on any longer.

I think you should call your insurance. It sounds like something they should cover but you would have to call and check. I'm sure your neighbor will understand and hopefully the damage isn't too bad. Best of luck, I know what you're going through, hang in there!
