New Construction Windows for Siding Projects

If you’re undertaking a siding renovation or building an addition, it’s an ideal time to install new-construction windows. These windows come with a nailing flange that attaches to the house framing, allowing for a very secure, water-tight installation before the siding or exterior finish is applied​In practice, this means we can remove your old siding, put in custom-sized new windows with proper flashing, then finish with brand new siding—achieving an as-new look and superior weather protection​.

By replacing windows and siding at the same time, you’ll also save on labor and ensure everything ties together perfectly. We only need to caulk and seal once, and you avoid undoing finished siding later to fit new windows​

Siding Window Combination Synergy

Herman Exterior Homes specializes in this siding–window synergy: our crews are skilled in both exterior siding work and window installation, so we coordinate the project smoothly. The result is new windows that are integrated with your home’s envelope from the start – no gaps, no make-shift trims – which means better insulation and no worries about leaks. If your siding is due for an update, we can install Viwinco new-construction windows (or the brand of your choice) as part of the project for a complete exterior transformation.

Benefits of New Windows

Greater Energy Efficiency - Modern windows are built to prevent heat transfer, keeping your home warmer in winter and cooler in summer. Features like dual or triple-pane glass with Low-E coatings and argon gas insulation dramatically reduce drafts and heat. In fact, upgrading old single-pane or failing windows can trim your heating and cooling bills by up to 30% by reducing energy, Energy-efficient windows help your HVAC system run more efficiently and keep indoor temperatures consistently comfortable even during Niskayuna’s freezing winters and hot summers.

Increased Home Value - Replacing your windows can boost your property value and offer a strong return on investment. Home buyers in our area tend to pay attention to the condition and age of windows. Not only do new windows make your home more attractive to buyers, but they also signal that the home has been well cared for. It’s a smart upgrade if you’re looking to improve your home’s value or prepare it for sale in the future.
