Editorial summary
MAC Waterproofing is a Norristown waterproofing service listed as a basement waterproofing contractor at 1421 Green Valley Rd #3562. The public data is narrow: the only stated service is crawl space waterproofing, and no website is listed here. Even so, the Google profile is fairly solid, with a 4.9 rating from 39 reviews and a phone number present. That makes it a practical directory entry for homeowners searching around crawl space moisture, standing water under a house, or related waterproofing concerns, while still leaving out details such as years in business, service area, inspections, or financing. Because the record does not confirm encapsulation, sump pump installation, vapor barriers, or drainage work, those should not be assumed. The strongest facts are the location, the review count, and the specific crawl-space waterproofing focus.
