Full-frame or insert replacement: which do you need?
Good window replacement Knoxville TN work starts with the frame. After inspecting each opening, we choose full-frame or insert windows. An insert works when the frame is square, dry and solid. Full-frame is the better choice when frames are damaged or new siding is going on.

Window Brands We Install
We install Andersen, Pella and VinylMax replacement windows, and we also help you compare them by budget, frame material and the look of your home.

Full-Frame vs. Insert Replacement
Insert (pocket) replacement sets a new window inside your existing frame, keeping your interior and exterior trim, and works when that frame is square, dry and solid. Full-frame replacement removes the old window down to the rough opening so rot can be repaired and the opening re-flashed to the wall’s water barrier, which is the better choice when frames are damaged or new siding is going on.
What Window Replacement Includes
- Measure every opening.
- Remove the old sash or full unit.
- Install full-frame or insert, as recommended for that opening.
- Flash and seal to the wall’s water barrier.
- Trim inside and out.
- Cleanup and haul-away of old windows.

Windows and Siding Together
If you are planning new siding, replace the windows at the same time. When the walls are open, full-frame installs can be flashed directly to the new house wrap, and trim is done once.
Windows for East Tennessee Weather
Knoxville sees roughly 36 days a year at 90°F or above and 66.6 nights at or below freezing (NOAA normals). So windows that seal well and are flashed into the wall keep conditioned air in and wind-driven rain out. We help you compare glass and frame options so they fit your budget.

What Affects the Price of Windows
- Brand and series.
- Frame material and color.
- Size and style: double-hung, casement, picture and more.
- Full-frame vs insert.
- Frame or sill repair.
- Interior and exterior trim.
Our Window Process
- In-home consultation and frame inspection.
- Written estimate with brand, series and install type per opening.

- Install, flash, seal and trim.

Frequently Asked Questions
What window brands do you install?
We install Andersen, Pella and VinylMax replacement windows, and we also help you compare them by budget, frame material and the look of your home.
What is the difference between full-frame and insert replacement?
Insert (pocket) replacement sets a new window inside your existing frame, keeping your interior and exterior trim, and works when that frame is square, dry and solid. Full-frame replacement removes the old window down to the rough opening so rot can be repaired and the opening re-flashed to the wall’s water barrier, which is the better choice when frames are damaged or new siding is going on.
Should I replace windows and siding at the same time?
In fact, it is a good time to do both. Full-frame windows can be flashed directly to the new house wrap, so trim is done once.
How long does window replacement take?
It depends on the number of windows and the install type. Either way, we give you a schedule with your estimate.
Do you offer financing?
Yes. We offer 18 months same-as-cash financing, subject to credit approval, so you can spread out the cost. Ask about it when we give you your written estimate.
Will you protect my landscaping and AC unit?
Yes. Floors and furniture inside are covered along the path to each opening, and beds below each window are protected before the old unit comes out. If exterior trim or siding has to come off, we add the Catch-All system’s netting and shields.
