Exterior Design Specialists is a Connecticut exterior company that, by its own account, Dan Cashman founded in 1985 to serve homeowners, architects and builders in the state. A 2025 Google customer said the company found that the original siding contractor had not installed the proper insulation and moisture protection, and that the team corrected it during the reinstall. That 2025 customer also said the crew left the job site neat and clean. Its Connecticut home improvement contractor registration, HIC.0525232, is active on the state registry. On the BBB, it holds an A+ grade.
Dan, I want to express our sincere appreciation for the excellent work you and your team completed at our home. You arrived as promised, provided a timely and detailed estimate, and performed the job with a high level of professionalism. We especially appreciate your attention to detail in identifying that the original siding contractor had not installed the proper insulation and moisture protection. Your team corrected the issue during the reinstall, and the results have exceeded our expectations. The crew was professional, courteous, and left the job site neat and clean. We are extremely pleased with the outcome and will not hesitate to use your services again. We’ll also be recommending Exterior Design Specialists to our friends and neighbors. Thank you again!
