A 2024 customer said water was coming up through the basement floor, that Frank showed up the same day they called, and that a couple days later he had a crew at the house to install a sump pump. That 2024 customer said Frank followed up a few days later, when more rain came, to check that everything was dry, and it was. A 2025 customer said they used Frank to add a sump pump in the basement as well as a driveway drain. That 2025 customer called his crew respectful and fast, and said he followed up after a big rain to make sure everything was working. A 2025 customer with a stone foundation said it "leaked like a sieve," that Rain King came the same day, and that the job was finished without any problems or glitches. A 2024 customer wrote that "When you call Frank will answer" and called the business "A true mom and pop place." **Strengths:** - Same-day response — a 2025 customer said they came the same day - Sump pump install — a 2024 customer said a crew installed one - Rain follow-up — a 2025 customer said Frank checked after a big rain ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Lists service areas in New York and Connecticut, including the Bronx, Westchester County, Stamford, Greenwich and Bridgeport _(confidence: high)_ - [Official Website](https://www.rainkingwaterproofing.com) — “About (self-reported, verbatim): Service Areas Bronx, NY Westchester County, NY Greenwich, CT Putnam County, NY Fairfield County, CT Yonkers…” - A 2024 customer said Frank came the same day and a crew installed a sump pump a couple days later _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSUNOOTVEdmhnRRAB!2m1!1s0x0:0x81ee6dde0491b7c!3m1!1s2@1:CIHM0ogKEICAgICN95DvhgE%7C%7C?hl=en-US) — “5★ With all the rain recently, we had water coming up through the basement floor - I was panicked but Frank showed up same day that I called…” - A 2025 customer said Frank added a sump pump and a driveway drain and followed up after a big rain _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnTUNROTRPUWJBEAE!2m1!1s0x0:0x81ee6dde0491b7c!3m1!1s2@1:CIHM0ogKEICAgMCQ94OQbA%7C%7C?hl=en-US) — “5★ Frank was great to work with and I felt honest and reasonable.
