Recent Review: We are really happy with our new windows! Modern Exteriors carries a few different brands, but we chose NT Windows. Windows and components made in the USA. The new windows are vinyl (metal-reinforced), dual pane. Very easy to open and close. They made a noticeable difference in our heating/cooling bill. And they block a LOT of sound. The house is much quieter with the new windows. Working with Modern Exteriors was easy; John answered all our (many, many) questions. They will definitely work with you on the price, so don't be afraid to ask. We signed the contract in March and the windows were manufactured and installed exactly eight weeks later, which is what we expected. Paid half up front and half on completion. Received the appropriate lien wavers when the job was done. Overall, we were happy with the installation. The crew removed our old windows and hauled them away. The new windows were installed, checked for proper function and sealed around the perimeter of the window. The aluminum trim around the windows on the outside looks great and really updates the look of the whole house. If we were disappointed in anything, it would have to be the trim on the inside of the windows. Some of our windows were double-hung, and the existing interior trim wasn't disturbed. But some windows were casement, and because of the placement of the hardware, the interior trim on those windows needed to be replaced. They did an OK job, but they're not finish carpenters, for sure. We had to pull out some siding nails that they had used for trim, and the caulking was a real mess! Took us some time to clean it up so we could paint the new trim. You might want to just do the trim and caulking yourself; it would have saved us time in the long run. But it's all taken care of now, and looks great. The installation took 3 days--but we have 26 windows, some on an upper floor, so it was a big job. We didn't get a lot of notice when they were ready to start; they called in the afternoon to let us know they'd be starting the next day. If you have to take time off work to be there, for the installation, that's pretty short notice. We handled it, but more notice would have made things easier on our end. We have two outside dogs, and we took them to doggie day camp so we didn't have to worry about the crew leaving the gates open and letting them out. Before we let the dogs into the yard each night we went around the house and picked up wood scraps, nails/screws and aluminum shavings so our dogs wouldn't get into them. The crew took care of most of it, but there were still bits and pieces left behind. No big deal. We would use Modern Exteriors again (and we did; they built a deck for us after this job) and we would definitely buy NT Windows again. It was a lot of money to spend, but we feel like we got our money's worth and added value to our house. UPDATE: One year later, and we still love our new windows! We have had zero problems with the windows and installation. Very happy with this purchase!
