JC Caulking is a Lawrence business built around one narrow trade: caulking, masonry restoration and waterproofing for building exteriors, on both commercial and residential jobs, per its own website. The company describes itself as small and employee-owned, and Google shows a 5★ average from 3 ratings, though there's no written review on file to say what any of those jobs looked like. There's a wrinkle in how long the company says it's been around: its site claims 23 years in business, dating back to 1998, while BBB — which grades it A+ but lists no accreditation, reviews, or complaints — records a 2012 start date for JC Caulking, LLC. The site also calls itself a "US Certified Contractor," which is the company's own description rather than anything independently verified. With no written customer accounts to point to, there isn't enough here to say how the work actually turns out — ask for references and get a clear answer on how long the current entity has actually been operating before signing anything.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from JC Caulking. Use it to sanity-check bids, then get the real number in writing.
Not sure which you need? Start with an inspection — many reputable companies assess free, and independent assessments run up to $500.
The wall run getting the drain — a full 30×40 ft basement is about 140 ft.
