"Craig the installer did a great job. I was pleasantly surprised by how sturdy the windows were - i picked window source's mid-tier level window. The day after my windows were installed the first storm of the season (snow, rain & ice) arrived and the windows completely performed as they should. I never realized what in eyesore my old windows were until i had these installed. i cant even tell how the wrapping on the windows improved the look of my house! I would definitely recommend window source & i did to a family member. Also, their quote process was quick, 1/2 hour to get a price. Window Source wasn't on my radar while i was requesting quotes on angie's list but they came up as a recommendation & i can't tell you how glad i am I hired Window Source to install all my new windows. A friend had windows installed by a popular chain & Window Source beat the quality and look hands down! If you are like me nervous about hiring a contractor you really know nothing about - i am here to tell you will be happy you hired Window Source. Thank you window source for making my 55 year old house look new!!!"

Universal Windows Direct of Manchester serves all of Central and Southern NH; we specialize in windows, doors, siding, and roofing. We carry our own exclusive brand of windows and siding called Unishield, and we have some of the best warranties in the industry. We are a preferred Owens Corning roofing installer. One of the key points that differentiates our window products from our competitors is that we use only virgin vinyl, built in one solid piece custom to each opening rather than standard sizes modified during installation. This creates a seamless fit that will not bend, crack, or warp over time. We also use the exclusive super spacer in between the panes of glass instead of metal, which is used by most window manufacturers. This amazing material almost completely diminishes any heat or cold transfer within the panes of glass, keeping you and your home comfortable and energy-efficient no matter the season!
"Great. It looks very nice. Two workers very professional"

FAQs for security door installation projects in Nashua, NH
The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
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.
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
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.
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.
