"They talk the talk but when push comes to shove they are awful. I had them do replacement windows. The windows that are visible from my driveway and sidewalk are excellent. The ones that are more hidden they didn't bother to wrap or caulk correctly. Called the office and they said that if they "fixed the issues" it would be more damage. Never have I been more disappointed by crap customer service."

"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!!!"

"I want to give my highest possible recommendation for Craig at Mel Martin Windows! I hired them when I found significant rot and decay in the wood around my front door. Craig came to our home, evaluated the situation and created a great plan to fix everything. We ended up replacing the wood around the door and installing an entirely new door. Craig did an exceptional job at recreating the decorative brick mold we had on the door frame by using PVC products. He corrected all the previous issues and now gave us a new solution that will withstand the weather for years to come. Extremely happy with his professionalism, punctuality, flexibility and pricing. He is a true craftsman and a pleasure to do business with. Very pleased with how our project turned out."

FAQs for window service projects in Portsmouth, NH
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.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
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.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
