About Us

As a family-owned and operated company servicing Oakland County and the surrounding areas, Grennan Construction has earned a reputation for honesty and integrity. Fair business practices, quality workmanship and superior customer service are some of the key reasons we stand apart from other companies. Founded in 1998 by Fred and Phil Grennan, Grennan Construction takes great pride in providing what many people feel is the best customer service in the business. We will take the time to get to know you and what you want and need in a home improvement project – allowing us to offer the solution that is best suited for you. Employees of our licensed and insured company will treat you like family – providing a free estimate, and delivering prompt, courteous and honest service. We will take pride in protecting your property – treating it as if it were our own. We are professional, neat, and efficient. We will follow up your project with a comprehensive customer satisfaction survey to ensure that we fulfilled every commitment and that you are 100% satisfied with the end result. Schedule an appointment with one of our project consultants to evaluate your situation and answer any questions you may have. Our highly-trained staff will locate and repair the most difficult leaks, install a complete roof and meet all of your siding, window, insulation, gutter and drywall needs. We require no deposit (on most projects) and no payment is due until your project is completed and you are satisfied! We guarantee all materials and the quality of our work.
