SealProMax Boston/Miami is a waterproofing contractor based in Abington, Massachusetts, using a proprietary sealing technology it calls SealGenius to stop water infiltration in concrete foundations and basement walls without demolition, serving both the Boston and Miami areas. Across 22 reviews on Google and Angi from 2022 to 2025, the pattern is consistent: reviewers name Rod (Rodrigo) directly and describe him as responsive and willing to explain the repair before starting. A 2023 review describes a basement sealed and fortified after flooding, and a 2025 review describes the process explained clearly from the first call through a final inspection, with high-quality materials and on-time work. Several reviewers, including a 2022 review, say the price came in lower than other quotes they had gathered for the same crack and leak repairs. Angi lists SealProMax as an accredited, approved business with a 4.9-star rating from 16 reviews and six years of experience on the platform, and every Google review is five stars. For a basement or foundation showing water infiltration, the years of specific, similarly described praise for the crack-sealing work point to a contractor customers trust to fix the actual problem.
⭐️⭐️⭐️⭐️⭐️ SealProMax Boston exceeded all expectations! From the first call to the final inspection, their team was professional, knowledgeable, and extremely efficient. They clearly explained the waterproofing process, used high-quality materials, and completed the work on time and within budget. You can tell they truly care about protecting your home and doing the job right. I feel much more secure now knowing my property is properly sealed against water damage. Highly recommended for anyone in the Boston area looking for top-tier waterproofing services!
