Introductory Video


Following a first meeting with John McManus, it was my pleasure to meet an honest, trustworthy person who gave me suggestions and choices for our garage doors. John committed to pricing, color and style with a time frame and completed everything on time and in perfect running order.

I highly recommend John McManus for garage door installation and workmanship.
