Most of the builders are way behind schedule with exterior issues. The homes being delivered to buyers at the PDI have no gutters or downspouts, many are missing siding and flashing details, and all of them have not had the lots graded.
With these above issues and with the melting snow and rain, I would not be surprised that many new homes have wet basements.
Make sure the sump system is working properly as there are many that are not. You can tell that whoever is installing the sump pumps and setting them up, left his head, finesse, talent, and common sense at home.
There is much to consider, feel free to call me if you have questions. I would be glad to help.
