See Why Massapequa Residents Love Window World

Had a patio door replaced with Window World. The door is of excellent quality. The installation was quick. The installer was polite and did an excellent job and left property clean when he was done.
Richard U.
Such an easy process! They came to me for an in-home consultation, took initial measurements, and before they left I had a quote in hand. We moved forward and in-depth measurements were done, then windows were delivered and installed in a few weeks. The install team was fantastic, efficient, and very respectful being in your home. A great process overall, the windows are beautiful, and the price was right.
Brian R.
Every part of this purchase was handled very professionally. The salesman, the telephone services person, the engineer who did the pre-install measurements, to the installation. The workers were very neat and courteous. They arrived on time and showed us that each window was operating correctly. We are very pleased with your company!
