"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Our sliding glass door was barely sliding – dragging would have been a more accurate word for it. Moses diagnosed the problem as more than just the need for new rollers, showed us where the track was excessively worn, obtained what was needed to repair the track rather than trying to replace it, and now our door rolls smoothly again. We are very pleased."

NOVA Exteriors, Inc. is a 12 time Angie's List Super Service Award Winner in several categories. We specialize in exterior remodeling and have over 50 years combined experience in the Metropolitan Area. We take pride in our work and we would appreciate the opportunity to showcase our services.

"NOVA Exteriors did a wonderful job replacing 3 exterior doors at our home. They checked every box one could ask for. Rob our sales rep was patient and understanding of our needs - even coming back a second time as we had a hard time deciding on what we wanted. Their team worked quickly and did a great job installing some beautiful new doors. We noticed after the installation that there were some imperfections on the hardware installed and they have agreed to replace them & their customer service was top notch. They responded quickly to some minor concerns and went above and beyond to fix the problem. While doors are never cheap, their price was right in line with other Provia vendors and 1/2 the price of Pella vendors. I'd highly recommend them."

Windows questions, answered by experts

Yes. Thermal pane windows can be customized to fit a variety of different window sizes and dimensions. A contractor or manufacturer can usually offer custom sizing options based on your specific window requirements. You should consult with professionals who can assess your needs and provide the appropriate custom window solutions for your home.

Options include interior, exterior, and double-pane storm windows. Choose based on needs and preferences.

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

In addition to window well covers or bars, you can take a few more steps to boost basement window security. Try motion-activated lighting; it scares off potential intruders by lighting up when someone gets too close. Strengthening your window glass with impact-resistant security film can also deter forced entry. A dependable home security system with window sensors and cameras offers real-time monitoring and alerts for added protection. Lastly, fostering good relationships with neighbors can establish a supportive community watch network, enhancing your home's safety.
