All You Need To Know


Joseph Daniels worked in remodel construction for several years. He wanted to begin working in the Architectural field and began studying Architecture at UC Irvine. When searching for a company to learn AutoCAD drafting to further his skills, he landed at a Roof Consulting firm. After mastering the CAD drafting and becoming a consultant in the building envelope industry, he set off with a partner to start D 7 Consulting in 1993. Since that time, D 7 has been involved in all facets of the Building Envelope Consulting business from Roof Evaluations and Replacements to Design, Construction Administration and Quality Assurance for some of the largest projects in the country. D 7 provides their services to all types of clients, including Architects, Developers, Property Managers, Owners, General Contractors, Lawyers and Individuals that just need someone to identify water intrusion problems.
