Lapan's Basement Waterproofing

Lapan's Basement Waterproofing is a family-owned business working out of the Lowell area, handling basement waterproofing, foundation crack repair, sump pumps and perimeter drainage across northeastern Massachusetts and into southern New Hampshire — its self-reported service towns run from Lynn and Newton up through Nashua and Newburyport. There's little independent record here yet. The one write-up on file comes from a Habitat for Humanity of Greater Lowell project, where a homeowner named Margaret said "John and his crew were fantastic, courteous, clean and responsive" after the crew installed a sump pump and French drain to keep her basement dry. One thing worth asking about directly: the company's own site gives two different founding dates — the home page says it's been "protecting homes across Massachusetts and New Hampshire since 1985," while the About page says "since 1970."
