Family Owned with Experience

Mark  and JoAnn are here for all of your window treatment needs!  We are a local business, not a big box store.  We do not pressure you to buy, we will help you decide which type of fabrics each room requires, and we measure the windows so you get a perfect fit.  We have samples of each window treatment, fabrics of everything we offer, so you know exactly what you are buying.  Installs are included in the pricing.  You don't have to do anything but sit back and relax.
