Window and Door Replacement in Westchester and Fairfield County

If a door is starting to go, or you’re feeling cold air escaping in winter and heat creeping in come summer, you’re describing the two things Westchester homeowners call us about most: aging windows and doors, and the energy loss that comes with them. Add hardware that’s hard to open, close or lock, or a seal that’s no longer effective, and it’s time to consider a replacement, whether that’s the two windows you know you need or a full-home upgrade.

Renewal by Andersen offers Westchester and Fairfield County homeowners long-lasting, energy-efficient replacements tailored to your home’s character. Book a free in-home consultation and see what true quality feels like.

Experience Innovation, Comfort and Lasting Results With Renewal by Andersen

Aging windows and doors can create safety concerns, lead to costly energy loss, let in unwanted noise and detract from your home’s curb appeal. Addressing these issues starts with choosing high-quality products and a trusted installation provider. When you upgrade with Renewal by Andersen, this is the service and experience you can expect:

Smooth operation you can rely on: Accurate measurements and professional installation mean windows and doors that open, close and lock the way they should with no more forcing a stuck window or fighting with hardware that’s had it.
Better energy performance: Renewal by Andersen windows feature Fibrex® material and optional High-Performance Low-E4® glass – a material that’s 56% more energy-efficient in the summer than ordinary dual-pane glass*, so less cold and heat escapes or comes in, for steady indoor temperatures year-round.
Strength and longevity: If a door or window in your home is starting to go, Fibrex® is a composite material that’s twice as strong as vinyl*, helping prevent corrosion, cracking and rotting* – no matter the climate.
A more comfortable home: Accurate measurements and expert installation create tight, effective seals that keep the air and insects out and help reduce outside noise.
Customizable products: Select from a variety of window styles, colors and hardware options designed to complement your home’s architecture.
A smart investment: From improved resale appeal to long-term enjoyment, our premium windows and doors can contribute added value to your home*.
