Editorial summary
Cosman Construction is listed in Boulder as a general contractor with crawl space waterproofing as the only service shown in the supplied data. The business has a Google rating of 4.6 from 35 reviews and a street address at 3401 Arapahoe Ave STE 303. A phone number is present, but no website, service area text, years in business, free inspection offer, or financing information is provided. That makes the public record fairly simple. The listing points to crawl space waterproofing work, but it does not describe encapsulation, vapor barriers, drainage systems, sump pumps, mold remediation, or foundation repair. Because the Google category is general contractor rather than a crawl-space specialty label, readers should treat this as a broader construction profile with one clearly stated waterproofing service. For directory purposes, the strongest usable facts are the Boulder location, the review count, and the crawl-space waterproofing service line. Anything beyond that would need confirmation from a website or a more detailed public profile. The record is still useful for local searchers comparing companies in Boulder, especially those focused on water intrusion under the house, but the listing itself stays narrow and does not provide much extra operational detail.
