Claim This BusinessWertz & Co has served Wilmington homeowners since 1982, building a reputation as a full-service exterior contractor handling roofing, gutters, chimney work, and fireplace installations. The company holds a Delaware contractor license and maintains accreditation with the Better Business Bureau, with an A+ rating reflecting its decades-long commitment to local code compliance. Across 84 verified customer reviews, the business maintains a 4.4-star average, with clients frequently mentioning the company's responsiveness and willingness to explain repair options before work begins.
The company distinguishes itself through manufacturer partnerships that few regional contractors secure. As a GAF Master Elite certified roofer, Wertz & Co can offer extended material warranties that independent roofers cannot match. The company also maintains active profiles across Houzz, Angie's List, HomeAdvisor, and Thumbtack, where homeowner feedback is independently verified, a transparency practice that larger firms often avoid.
Customer stories from recent reviews reveal the day-to-day experience of working with this crew. When Gail needed a chimney liner, technician Terry coordinated the job, and installers Frasier and Keenan arrived early, explained the scope, and completed the work cleanly. For a mid-century modern renovation, Ted Jacoby worked directly with Tom to select appropriate materials for roof, gutters, soffits, and board-and-batten siding. Another reviewer, Steve, noted that installers Dave and Steve finished a gas fireplace installation ahead of schedule while answering "a thousand questions" about the new unit. These named technician interactions suggest a culture where crews take ownership of customer communication rather than dispatching anonymous workers.
Three of four detailed reviewers awarded 5 stars, praising specific technicians like Terry, Dave, and Frasier for professionalism and clean work. The single 1-star review cites a chimney repair performed for a previous homeowner, noting the work required expensive corrective repairs just months later, a customer experience that differs sharply from the overwhelmingly positive feedback.
