"I can't believe we didn't replace our windows sooner. Jackie from Window Place Plus took diligence in understanding our goals and concerns for window replacement. Her installation team were professional and detail-oriented. The cost and quality of the windows that we purchased were very reasonable. About a month now after the replacements have gone in and the whole family, even our kids, can tell a big difference in the air and heating comfort now compared to before with the old windows."

"DO NOT HIRE--ESPECIALLY TED!!!! Not only did he give me one price and then keep racking up the charges not once-but twice, he also refused to fix the damages that occurred to my property as a result of his construction. Once he realized he was not getting a check until the damages were repaired, he changed his tune. The next day after the work was done, there was still leaks in my roof and they had to come out again to fix them. Then when the bank made an error with my check, Ted called me 5 times a day and texted me repeatedly demanding payment despite the fact that there was nothing wrong with the check I gave him other than a clerical error. I felt harassed and anxious. Every time my phone vibrated for a day and a half I felt unsafe. For peace of mind, DO NOT HIRE!!"

FAQs for window and door contracting projects in Williamstown, NJ

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.
