One of the most important aspects of a successful window project is the actual production MEASUREMENT of your windows. 

If they are not measured right, they will either fit too tightly (out of square) and not operate smoothly, or fit too loosely, allowing air leakage and loss of visible light.

Seaway’s commitment to getting the measurements correct rests in the capable hands of our employees who specialize in this work and do it every day.

“I've been installing windows and patio rooms my entire adult life. I can say for certain that Seaway Manufacturing offers the very best products in the business. There is no substitute for quality, especially for windows and sun rooms. Windows are some of the hardest working components in your home. They have to operate 24/7. Seaway Manufacturing has been making the best windows, sunrooms and entry doors in the world for over fifty years. They have thousands of happy customers all over the United States.”
