Premium Window Frame Materials

Custom Exteriors offers high-quality window frame materials that have their own unique advantages.

Fiberglass Replacement Windows

Fiberglass replacement windows, like our selection from Infinity from Marvin, offer exceptional strength, durability, and energy efficiency. Fiberglass frames resist warping, swelling, and shrinking even in extreme temperatures, making them an excellent choice for Union City’s varied climate. Homeowners looking for a long-term solution that combines beauty and performance often find that fiberglass windows offer one of the best returns on investment.

Vinyl Replacement Windows

Vinyl replacement windows are a popular, cost-effective choice for many homeowners. They provide excellent insulation, potentially helping lower energy bills and maintaining indoor comfort. Vinyl windows are available in many colors and styles, and they require virtually no maintenance—no painting, staining, or refinishing needed. For homeowners seeking energy-efficient replacement windows at an affordable price point, vinyl is a reliable and attractive option.

Wood Replacement Windows

Wood windows offer a timeless, classic look that enhances the natural beauty of any home. They provide excellent insulation and can be customized with stains or paints. However, wood windows typically require more maintenance than fiberglass or vinyl, including regular painting or sealing to protect against moisture and weather damage. For anyone who values authentic craftsmanship and is willing to invest in upkeep, wood windows can add warmth and charm to a home.

Diverse Types of Replacement Windows

When planning a replacement window installation, it’s important to choose the right window styles to match your home’s architecture and your personal preferences. Popular types of replacement windows include double-hung windows, which offer classic design and easy cleaning; casement windows, which swing outward for excellent ventilation; and sliding windows, which are ideal for spaces with limited room for opening. Picture windows provide expansive views and let in abundant natural light, while awning windows are perfect for ventilation even during rainy weather. For homeowners looking to add dimension and character, bay and bow windows create striking focal points and additional interior space.

Replacement Window Cost & Financing Options

The price of a window installation project can vary based on multiple factors, including the size of the windows, the type of materials selected, and the installation complexity. Custom Exteriors believes in transparency and providing clear, upfront pricing. Our knowledgeable team will guide you through all available options, discuss your needs and budget, and help you make informed decisions.

"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."
