JES has done multiple projects (inside and out) at our Capitol Hill home for 20 years, and we continue to go back to them due to employees like James Teixeira, the JES General Manager in the Manassas, VA, location. James is exceptional. His professionalism, and his extensive knowledge of construction and of waterproofing are impressive. James was instrumental in fixing a complicated issue at our house. Equally important to us was his personal character - his integrity, kindness, and incredible patience (again, it was a complex and time sensitive project). He is respectful towards everyone. We have dealt with dozens of contractors/vendors in the DC metro area, and James Teixeira is truly one of the best. He is thorough, very responsive, and he goes above and beyond. Construction and water issues can be extremely stressful, but when you are in James' care, his competence and commitment to customer satisfaction give you peace mind. We are most grateful for James and JES.
