Three ways we install

Each method balances durability, style, and warranty differently. We'll recommend the right fit for your home during your free estimate.

1

Premium Performance

Our most durable installation — the method you generally find in new-construction homes. It's so thorough it comes with a lifetime warranty that's transferable to all subsequent homeowners for the life of the home.

2

New Retrofit

A durable install that includes a nail flange and new trim on the house. Adding trim not only improves performance, it can add new dimension and style to some older homes — backed by a lifetime warranty for as long as you own your home.

True Retrofit

Our least-invasive method — no cuts to the siding and no new trim. This technique lets your home keep its classic style and charm. Long-lasting, though less durable than our other installs.

Why It Matters

A great window is only as good as its install.

The right installation method protects your investment, improves energy performance, and keeps your home looking its best. Our crews are trained on all three methods so you get the proper fit — not a one-size-fits-all approach.
