FAQs About Our Replacement Window Installations

How can I tell if it’s time to replace my windows?

Knowing when to replace your old, worn-out windows is key. If your windows are letting in drafts, becoming difficult to operate, or showing visible wear like rotting frames or foggy glass, it's likely time for an upgrade. These issues can lead to higher energy bills and reduced comfort. Replacing them can restore both efficiency and peace of mind.

What advantages come with installing new windows?

New windows offer more than just a cosmetic update—they can boost your home’s insulation, lower energy costs, and minimize noise from outside. They also enhance curb appeal and add value to your property. With modern technology, today’s windows deliver both style and high performance.

Do replacement windows help with energy savings?

Yes, our replacement windows are designed with energy efficiency in mind. We work with leading manufacturers like Infinity from Marvin, whose products feature advanced glazing, low-E coatings, and insulated frames. These elements work together to regulate indoor temperatures and reduce strain on your HVAC system.

Why should I choose energy-efficient windows over standard ones?

Energy-efficient windows provide better thermal performance, helping to maintain a consistent indoor climate and reduce utility costs. They also reduce the environmental impact of your home by lowering energy consumption. Over time, these benefits can lead to significant savings and improved year-round comfort.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse.  One was a custom window that required extra work in refitting the plantation shutters to the new window.  Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up.  I would recommend Custom Exteriors."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
