- License status — public records show expired or inactive credentials
- Customer service — one 2024 reviewer reported a hostile phone interaction
- Complaint response — BBB cites one unanswered complaint
McNamara Waterproofing is a Worcester sole proprietorship that BBB lists under waterproofing, basement waterproofing, masonry, and paving-stone work. BBB says the business has been operating for 58 years and identifies Joseph McNamara as owner. The public customer record is extremely thin: Google shows one rating, a 1-star review dated June 2024. That reviewer described a hostile phone interaction while seeking service information and said the call ended with the front-office worker hanging up. There is no detailed work account in the available review record, so the public material does not establish workmanship or project outcomes. Credential status requires particular care. The Massachusetts license record for 122565 is registry-verified expired, and BuildZoom lists that record plus licenses 114326 and 179128 as inactive or cancelled; it reports two permits but no active license verified. Confirm current licensing, insurance, contract scope, and complaint resolution directly with the relevant Massachusetts authority before considering any waterproofing or masonry work.
