The classic New England window. Both sashes slide up and down, and both tilt in so you can clean the outside glass from inside.

Hinged on the side and opened with a crank, a casement swings out to catch a full breeze and presses against its seals when closed.

Last year we had a real need to replace our windows, which were 28 years old and really starting to show wear! We knew we wanted to go with vinyl but also wanted to retain our stained woodwork inside our home. We did our research and decided to give Castle Windows. Our Sales rep, Josh, was very professional, easy to deal with, and clearly knew his stuff. We chose windows that had a medium oak finish on the interior. The windows were ready in the timeframe promised and installation was scheduled. The install process was very efficient and we were very pleased with the results. The color of the windows matches our interior woodwork perfectly! We are so pleased, we just ordered our final window (a bay window) and a slider. We highly recommend Castle Windows. Dealing with the regional owner, Franc, and our sales rep Josh was a pleasure. They both treated us with honesty and integrity and were very accommodating to our specific needs!Posted on Google![]()

We had a sliding door installed by this company and had a great experience from start to finish. They worked with us to come up with a very reasonable price, which I really appreciated. The installation was done professionally and efficiently, and the quality of the work shows. I absolutely love the sliding door — it looks beautiful and functions perfectly. I would definitely recommend them!Posted on Google![]()

We met Castle Windows at the Topsfield Fair grounds at the business fair. The salesman was very informative, and we made an appointment for someone to come to the house. A pleasant, knowledgeable salesperson sold us the top tier replacement windows, and they were installed. All but one fit properly, but the last window will be installed in a few weeks. Our home is now quieter, manages the heat and AC cold much better with these new windows. The workers were neat, polite, and the installation was completed in one day. When ever I had a question a knowledgeable person answered promptly and even walked me through the process of using the loan process they use. Thank you to the people of Castle Windows.Posted on Google![]()

They replaced our patio door and small window upstairs. A+ job at a good price, install only took a day, and they were great communicators. I’ll use them again.Posted on Google![]()
