The best thing about Lenny Santosuosso and Applewood is, they took what we said we wanted and made it much better than we ever imagined it. We had a rough idea -- blow out a wall, build an addition, and get a new kitchen. Lenny took that input and designed an amazing space that incorporated...

They started work in May of 2013. They came and preformed work that was more than sub standard. They tried to build a new deck and then came back three times to fix it and it just kept getting worse with every attempt to fix it. They put all new doors in the house and none of them are...

FAQs for window and door contracting projects in Twin Mountain, NH
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.
