"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"

"My front door was hung in a crooked door frame and would not close or lock all the way. I also needed to install 2 new storm doors, one in that crooked door frame. I’m on a limited budget, and Nixon was able to correct the door lock situation, compensate for the frame, and install the storm doors beautifully. Everything now works perfectly and looks amazing. He recommended the perfect storm doors and hardware and even picked everything up for me. It was all finished in 2 hours! Highly recommend!"

"2nd time I’ve hired Diego to make a custom glass door for a bathtub. His workmanship is excellent and that of a perfectionist. Very clean. Goes over all of the details before doing the project, gives a quote on the price, and then keeps to the timeline to get the job done. No fuss. No mess. Can’t ask for anything more."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

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.
