"I went through numerous window companies and received many quotes and Good Fellows Window Corporation was by far the best in not only price but professionalism. Gary Greene, the owner, is professional, friendly and very personable. His prices were very reasonable...he was honest and not pushy at all. he was available at all times throughout the whole process from the estimate to installation. His crew was AMAZING! they were on time, clean, meticulous about the installation of each window and door. they took their time and made sure it was done accurately. they did not leave a speck of debris in or outside my home. I would completely recommend this company if you need new windows or patio doors installed. I had a stress free experience all due to Gary and believe me I was initially stressed out after meeting with so many companies and getting some crazy quotes. I'm happy I hired them and the job is complete and I am TOTALLY HAPPY...thanks again Gary and Crew"

"After getting quotes from three major glass shower door installers, I decided to take a chance and go with Diego and I'm so glad I did! Diego did a great job installing a high quality, tempered glass door in our master bathroom that is a bit "tricky." More importantly, his price was well below the competition! Diego was also very professional, showed up on time, and answered all of my questions. Thank you, Diego!"

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.
