★★★★★

"I phoned SJ Waterproofing Pros close to 10:30 at night after noticing water entering through the window well during a major storm. A live dispatcher picked up right away — not an answering service. A crew was at my Wilmington, IL property quickly enough to prevent serious damage. That kind of urgency in Wilmington, IL is not what I expected from a large company — they were faster and more professional than I'd hoped."
