Casement Windows

Modern Design. Effortless Operation. Superior Energy Efficiency.

INQUIRE NOW

If you’re looking for windows that combine style, function, and exceptional performance, casement windows are the perfect choice. Hinged at the side and opening outward with a smooth crank handle, they bring fresh air, natural light, and unbeatable energy efficiency to any room.

At Boston Doors & Windows, we install high-quality casement windows designed to handle New England’s unpredictable weather — with craftsmanship and care you can trust.

What Are Casement Windows?

Casement windows open outward like a door, operated by a simple hand crank. This design allows full top-to-bottom ventilation, making them ideal for kitchens, bathrooms, and any space where airflow matters. When closed, the sash presses firmly against the frame, creating one of the tightest seals of any window style.

Why homeowners love them:

  • Opens fully for maximum ventilation

  • Easy-to-use crank operation — perfect for hard-to-reach areas

  • Tight, weather-resistant seal when closed

  • Unobstructed views with a clean, modern look

  • Pairs beautifully with picture or bay windows for panoramic views

“We needed new doors for our bathroom and laundry room that were literally falling apart. They were obviously very cheap, particle board. I connected with Joe via Yelp on a Sunday afternoon and by the following Wednesday morning - all doors were replaced! That included a site visit to do the measuring - ordering - picking up the doors, and the final installation. His estimate was very fair for the value - and the final price was exactly as expected. He didn't mark up the materials either. He was prompt, professional, and did excellent work - hold away all the old doors and clean things up beautifully. He even helped me out with a few doors in our 1910 house that have never really closed properly - and without hesitation, offered to help sand them down to get a proper fit. I think it's the first time in over 20 years that we've been able to actually close our upstairs bathroom door to lock it! If I could give Joe six stars, I would. Highly recommend!”
Paul R.Dedham, MA
“I highly recommend Joe. He is an expert carpenter, and knows what he is doing. He repaired our front steps, which had been rotting from water damage, replaced our bulkhead (which has been bad for a while, and somehow, other people couldn't do it???) and replaced our back door steps and landing with smart materials. His prices are more than fair, and I will be having him back for more repairs and interior painting on my Victorian home. Joe has an excellent manner, and really, really, will identify a problem, and then fix it. Beautifully. Honestly, I (jokingly???) told him our house wants to go steady with him. You will not find a better, more trustworthy, or personable carpenter, or Person to work with your home.”
Barbara M.Brookline, MA
“Joe is absolutely wonderful in so many ways! He is extremely responsive and dependable. His communication is above and beyond all other contractors I've dealt with in the past, as well as his quality of work. He responds quickly and always shows up when he says he will. I find all of this to be very rare nowadays. He replaced a back hall screen door and window and picked out top quality products without top prices. He also replaced a storage door and lattice under the front stairs. He completed each project in less than a day. His work is meticulous and top notch, as you can see in the many photos posted in his reviews. Joe is also very friendly and great to talk to! He's just such a nice guy! It is such a good feeling to know I have someone I can count whenever I need repairs. So DO NOT hesitate to call Joe! You will be SO glad you did for all the above reasons!”
Debra D.Revere, MA
“A very belated review for Joe. We reconnected with him for another project that was similar to our first -- convert a small open space to a closet with shelves. The finished product was top notch and we could not be happier with how it turned out. Joe is a professional and very easy to work with. Our experiences with him have been amazing and we appreciate his thoughtfulness and ideas.”
H L.Boston, MA
“Joe was really great to work with and I highly recommend him and Boston Doors and Windows. He came out to look at my project right away (replacing the frame and door on my basement), and gave me a clear quote so I knew what to expect. He always showed up on time, was friendly and clear, and the end result was spectacular. His work is great, he was easy to work with, and I plan on hiring him again for other projects around my house in the future.”
Alison E.Medford, MA
“This guy is a real pro. He is a specialist in doors, windows and trim work, and is very organized! I had a fire rated door into the garage that needed replacement. He responds, comes by and gives you a very reasonable quote, he orders the new door, comes back a few days later with the new door and all materials, does a great job, takes the old stuff away. Billing is easy, he is great to deal with. Highly recommend!”
Tony R.Belmont, MA
“Joe does amazing work and is amazing to work with. From the beginning, he was prompt, efficient, and communicative. He installed a front door for us - as new homeowners, he helped walk us through the decisions in advance, and did a pristine job on installation. He is a delight to work with, and the quality of his work is high. Would highly recommend him for any job you need.”
Sara O.Medford, MA
“Joe replaced two windows and fixed some damaged popcorn plaster in our bedroom. He was super communicative and responsive about every step (quotes, scope, ordering materials, installation date), very friendly, did excellent work, and left the room extremely clean. He even answered some questions that I had about our house, beyond this project. We hope to hire him again for any other projects that come up, and will recommend him to all our friends!”
Chloe R.Somerville, MA
“Joe is the owner of this business and he is amazing. He is always on time, gives you the price before work starts and keeps his word. He delivers excellent results. I am very pleased with his quality of work too. I am very happy I hired Joe to do my windows project. Overall it was an excellent experience.”
Toma G.Newport, RI
“Joe was great to work with to repair our damaged baseboard. I was able to get a hold of him quickly after request a quote through Yelp, and he was able to quickly give me an estimate on the work after a few pictures and details. Joe arrived early in the morning to start and was done in less than 2 hours. He even grabbed the baseboard for me so I didn't have to run to Home Depot. He was friendly, professional, and fast. I thought the pricing was fair, and I would recommend him to anyone needing quick work done in short notice.”
