Why Should You Replace Old Home Windows

Typically windows last 10 to 80 years. Call in a professional for window replacement once you start to notice the signs that your windows are at the end of their lifespan. Replacing windows will save you money on utilities while improving the security, comfort, and appearance of your home.

At Green T Services, we use Low-E glass and vinyl frames for every window. Low-E glass is proven to reduce the UV rays from the sun, protecting windows from radiation, making them energy efficient and ENERGY STAR® certified. 

Vinyl frames are resistant to the expansion and contraction that comes with changing weather. The combination of these features leads to high-quality, eco-friendly windows that lower energy bills and last longer.

No matter the style of window you choose, our installation process is fast and straightforward. 

Our certified window installers will come to your home and measure for new replacement windows and send the dimensions to our trusted manufacturers. Once the windows are ready, our technicians will return to install your replacement windows.

Types of Replacement Window Installation


Double-hung windows feature two sashes that tilt in and move up and down. These windows are great as a low maintenance, easy to operate choice.


Sliding windows can be customized to fit the size and style requirements of your home. These windows are easy to clean and versatile, making them great for large spaces.


This secure and stylish option uses hinges to attach frames to the sides of the window. Casement windows feature a center bar and come in bay, twin, bow, and triple configurations with either blind panel inserts or glass blinds. 


These windows are fixed in their frame and provide an excellent view of the outside. Picture windows are the perfect addition to large rooms.


Garden windows feature a top pane that resembles a roof, creating a box space that allows plants to bathe in sunlight. Garden windows are best for kitchens because they are angled 90 degrees from the wall.

Bay & Bow

Bay and bow windows have panels that project outwards from the home’s exterior. These windows let in natural sunlight and open up the room, making them a fantastic addition to rooms with large walls.

Awning and Hopper

Awning windows swing open from the top to create a barrier that keeps rain out and lets in sunlight. Hopper windows feature a hinge at the bottom with a sash to open inward and bring airflow into the home.


Despite the name, we can do basement window installation in both basements and attics. These windows are usually in awning, hopper, or slider styles that bring fresh air into the home. Also called escape windows, they are perfect for providing a safe escape in an emergency.


Egress windows are large enough to be used as an entry and exit point. These windows are ideal in an emergency and feature steps or a ladder for this purpose.


Searching for a unique look? We are happy to offer custom window designs to meet your needs. We will work with you to create the ideal window for your home.

Russell, Boeman

From start to finish the carpet cleaning job was everything and more than what was expected. The quick response and over the phone quote was very specific and task oriented to make sure all information was accurate.

I feel SO fortunate to have discovered Green T Services and learn the variety of services they provide. Recently, Brian G. (who turned out to be much more than a handyman), successfully completed a couple projects at my home. Brian's knowledge, efficiency, and professionalism, in addition to his friendliness and patience with me watching him and asking lots of questions was fantastic. Even with his attention to detail, he completed the work in the estimated amount of time and cost. I am now making a list of other needed work I will certainly call Green T for assistance. Thanks Brian!

Brian performed handyman services for my apartment. He hung up tons of pictures and paintings with lightning speed. His work was immaculate. I was so impressed by his level of professionalism and quality of work. I am so happy I hired Green T Services for this job. Brian did a much better job than I ever could have, and my apartment looks fantastic now. I will be recommending Green T Services to all of my friends and family for every one of their home improvement service needs.

Justin cleaned all our vents, and also cleaned our carpets. He was professional, friendly, and very informative. He told us exactly what he was going to do and how it was going to work, before beginning any work, and afterwards, he was good at telling us what had been better or worse than expected. We very much appreciated the information. He managed our expectations appropriately, letting us know which stains he probably would NOT be able to remove (for example, ones that had been there long enough to set). We would definitely use the company again, and hope to have Justin back if the work was suited to him!

I had Daniel Liscano as my technician today and his service was SUPERB! He was professional, nice, courteous, and went above and beyond to ensure I was a happy customer. I had three different services completed in my house and Daniel did not cut any corners on any of them. He was here all day from 9-5 and he worked very hard alone to clean, sanitize, deodorize, and disinfect my house. From the air duct cleaning, hardwood floor cleaning, and carpet cleaning, Daniel completed an EXCELLENT job! This is something I had been wanting to do for a long time and finally took the time to schedule the appointment and I am really happy I did! I can breath better and my allergies are not bothering me as much already! Thank you Daniel and thank you Green T for delivering on your promise of service and professionalism! It was worth every penny! I will be ordering more services soon!

Danny was the Air Duct Technician who assisted us. He was absolutely phenomenal! Danny was courteous, friendly and explained in detail. He walked me through all the steps, set proper expectation and followed through. I appreciate Danny for going above and beyond. I will use Green T again and I would recommend their service.
