National Vinyl Products

We did not use this company for installation but did buy 30 in total double pane replacement windows for our apartment building. The windows are of an excellent quality. Any problem that we had they took care of immediately. Farnsworth Lumber in Shirley Ma is where we ordered these windows from and what brand of windows they recommend. Ken Farnsworth, the owner of Farnsworth Lumber, was extremely knowledgeable and helpful. These are wonderful windows.

This was my go to place for several hundred windows manufactured to my requested RO size for over 20yrs. Since Fran retired they are directing me to a lumber yard instead of buying direct. Price increase of 70% in just over a year? NO Thank you!

Of the almost 30 years installing windows, this is the only company that has withstood the test of time, by updating products, keeping pricing stabilized, communicating effectively, owning up to any errors, delivering on time from the owners to the delivery men this company is 1st rate and why we sell & install NVP windows!

Fran totally forgot about the replacement sash I needed. Then when the day came for it to be installed, it was the wrong size. All because Fran told me he had all of the info he needed from the picture of the tag I sent him. My wife and I are so disappointed with the whole process so far. It's a good thing Patrick knows what he's doing.

This is my fourth year in my new home with National Vinyl windows. I purchased 29 triple glazed windows and 3 double glaze windows from them. They were very affordable, very eco-friendly and I am extremely delighted with their performance. Yes I had a couple of minor issues with 2 of the windows, and when I had those issues they sent their repair guy out and he took care of them (seals on the outside made the closing process hard).

Take a look at what the big box stores offer and charge for double glaze so-so windows and then get in touch with National Vinyl and ask about their triple glaze windows. FANTASTIC overall performance; insulation is solid both in cold winters and hot summer times, and noise reduction is terrific. You might pay a few bucks more for them compared to what Home Depot can give you, BUT you will get a very high performing window (its your house so do it right). They are a great small manufacturer that focuses on quality high-efficiency windows with great service and great prices!
