Our shop is on the I-12 service road in Ponchatoula, about 9 minutes from Hammond, so a Hammond call doesn’t wait on a drive across the lake.


Hammond sits in the pine flatwoods of Tangipahoa Parish, on the Natalbany River drainage that empties south into Lake Maurepas. The ground is higher than the lake towns to the south, but higher ground doesn’t stop Gulf humidity, which keeps moisture against slabs and crawlspaces from May through October.
That’s why we start every Hammond visit with a load calculation and moisture readings, then size, seal and drain the system for the house it’s in.
About 9 minutes and 5 miles from our shop on the I-12 service road by way of I-12 and US 51 Business.
