One opening or a larger update.
Start with the approximate number of windows, which parts of the property are involved and what you want to change. Exact measurements are not needed to describe an initial inquiry.
Replacement and installation.
Explore vinyl, wood and aluminum windows in styles and shapes that complement the building. Discuss existing openings, casement or sliding styles, operation and how the installation meets the surrounding exterior. Older or unusual openings may need a custom-sized solution.
A window repair concern.
Describe the problem and what you know about the existing window. The scope may depend on the unit, parts and condition.
Commercial and multifamily properties.
Include occupied areas, access, building requirements and any planned phases of work.
UNDERSTAND YOUR EXTERIOR
Understand the details around your view.
Know what belongs to the window and what belongs to the installation before comparing proposals.
Open a part to read its description.
Tap the drawing or choose a part. Open its label to learn what it does.
Frame
The fixed outer structure that holds the sash.
Why it matters Its fit and support matter to the installed window.
Ask in your estimate “Is this an insert or a full-frame replacement?”
Read the reference: Andersen window parts guide
Sash
The glass and surrounding rails that move in this double-hung example.
Why it matters It determines how the window opens and closes.
Ask in your estimate “Which parts operate, and how will operation be checked?”
Read the reference: Andersen window parts guide
Insulated glass
Two panes with a sealed space between them in this example.
Why it matters The specified glass package affects the unit’s performance.
Ask in your estimate “Which glass package and whole-window ratings are quoted?”
Read the reference: Andersen window parts guide
Weatherstripping
Flexible seals where moving and fixed parts meet.
Why it matters These seals help limit air leakage when the window is closed.
Ask in your estimate “How are the seals and closing fit checked?”
Read the reference: Pella weatherstripping explanation
Sill & drainage
The bottom of the window and the drainage detail below it.
Why it matters In a drained installation, any water that enters needs a controlled path back outside.
Ask in your estimate “How will the sill drainage be preserved?”
Read the reference: Andersen window water-control installation
Installation perimeter
Flashing outside and an air seal at the interior connection.
Why it matters The window must connect to the wall’s water and air control layers.
Ask in your estimate “What flashing, air sealing and trim restoration are included?”

Selective cutaway, not to scale. Casement, sliding and fixed windows operate differently. Insert replacement may retain the existing frame; full-frame work exposes more of the opening.
Compare the details that matter.
Ask about frame material, style, operation, finish, glass options and product-specific care. Discuss installation details, related trim or siding work and the written terms that apply to the selected product.
USEFUL ANSWERS
Before you get started.
Do I need exact measurements?
No. For an initial request, provide an approximate window count, property location and description. Measurements and installation details can be discussed as the scope develops.
Can windows be part of a siding project?
Yes. Include all the exterior work you are considering so transitions, trim and the overall scope can be discussed together.
Can you advise on a repair concern?
Describe the issue and existing unit. Whether a repair or replacement is suitable depends on the product and condition.
What determines pricing?
Window count, size, style, material, existing conditions, access and related installation work affect the estimate.
