1. We measure
We spend about an hour at your house, measure every opening, show you samples and give you a written price.

2. We build
We custom-make your windows to those measurements, which usually takes a few weeks. We'll give you a date when you order.

3. We install
Our own crew does the work. They cover your floors and furniture first, then square, seal and trim every unit.

4. We clean up
We haul away the old units and leave the house as we found it. Most homes are finished in a single day.

Garden questions.
Will it leak heat with all that glass?
It has more glass than a flat window, but it's the same Low-E, argon-filled glass in an insulated frame.
Can it fit in my existing kitchen window?
Usually. It's custom fabricated to the existing opening, and we'll check the size at your free measure.
What grows well in it?
Herbs like basil, parsley and chives, plus trailing houseplants. Most things that like bright light are happy.
Does the shelf come with it?
The plant shelf is an option. Tell us if you want it and we'll include it in your price.
