"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"From the quote to the completion of the installation, we were very happy that we chose Unicorp. We did a full (28 windows) window replacement and 1 exterior and storm door replacement. The windows are the Prodigy by Uncorp windows and they are beautiful and well-made, and the price was more than competitive with the other quotes we received. Our house is 100 years old and still had the original windows, so it was a very challenging and lengthy installation, but their installer did an excellent and very thorough job. We plan on using Unicorp again in the future when we replace our remaining exterior doors."

"Nova Exteriors recently replaced our 43-year-old patio door, which was in terrible shape, with a ProVia Endure door. Nova's representative, Sam Osta, arrived on time, gave us a thorough explanation of why ProVia's Endure door would work well in our home, stayed as long as we had questions, and didn't try to upsell us on "bells and whistles" we didn't need. Nova's crew did an excellent job of installing the door, working efficiently and cleaning up when finished. Now that we've used the door many times since the installation, we can attest to its ease of use, especially the dead-bolt safety feature at the door's bottom that operates with an easy touch of a shoe. And it looks beautiful as well. We highly recommend Sam Osta and Nova Exteriors for patio door replacement."

"Chapin Handyman does excellent work! We needed our basement windows (which had just been replaced by another contractor) to have either a trim border or wallboard put around them and decided to get caught up on a few other tasks that we just weren't getting around to. Nestor was very responsive for giving us a price, broken out by project. Each worker who came through (a) knew what was asked for from Nestor and also (b) double-checked the needs with us. The windows look *amazing* and we're really happy to have the ceiling fans switched out, our towel rack back up in the master bath, and the installation of a proper basement light switch (after making a bad call on not putting it in when we finished it years ago.) We can't recommend them enough!"

Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.
If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
