Why Choose Grennan

Why choose Grennan Construction for your new replacement windows?

  • The two most important things to think about when choosing new windows are the right window and the right company. Our goal is to make installing replacement windows one of the best decisions you will ever make when it comes to improving your home.
  • Some companies try to push one brand of windows to everyone. Grennan Construction offers several brands of quality windows so you can be sure you find the right fit for your unique needs and style. We offer Anderson, Atrium, Paradigm, Ply Gem, and Weathershield.
  • We help simplify the process. Our project consultants sit with you in your home, measure and examine your existing windows, and go over your options and answer any questions that you may have.
  • You don’t have to worry if you are doing the right thing to solve your home improvement needs and dreams. If you are having a problem, our project consultants are trained to properly diagnose the problem and help you identify the best solution for you.
  • During installation we will protect your property and do a proper cleanup at the end of each day. We will treat your home as if it were our own. We stand behind our work. Your windows are backed by full manufacturers’ warranties, and our twelve+ years in business.
  • Your home will not be at risk. We are fully licensed and insured – including Workers’ Compensation. We take the stress out of financing your project. Budget and financing plans are available.
