"I phoned SJ Waterproofing Pros around 10:30 at night after noticing water pooling through the window well during a heavy rain event. A real person answered on the first ring — not voicemail. A crew was at my Great Neck, NY property faster than I expected. That response time in Great Neck, NY is not what I expected from a large company — they exceeded every expectation."

★★★★★

"The estimate SJ Waterproofing Pros gave me prior to any work beginning was identical to the final bill — to the dollar. After getting burned on pricing by two previous contractors, that pricing consistency is worth more than any discount. I've told three neighbors to SJ Waterproofing Pros in Great Neck, NY since we had them out."
