CJM Waterproofing

CJM Waterproofing is a Haverhill company whose entire listed trade is keeping water out of basements and foundations — foundation sealing and waterproofing systems, residential and commercial, per its Angi page, which puts the company's experience at nine years. That page is also all there is. Angi lists the business as new on both Angi and HomeAdvisor with no reviews yet, so nothing from anyone who has actually hired them is on the record. Two specifics from the listing are worth weighing first. Angi's FAQ says the company does not offer warranties — that matters more than usual on waterproofing, where the question is whether the fix holds a few winters out — and no licence or registration number appears on the page, which notes such claims come from the business itself. Estimates are free, credit cards are accepted, and there is no emergency service. Worth a call for a free estimate if you are collecting basement-water quotes around Haverhill. Get the warranty terms in writing, ask for the registration number and check it with the state, and ask for two recent local jobs you can look at.
