The Process

What's included

1

Exterior & interior options

Choose exterior-only cleaning or add interior glass — priced separately, so you only pay for what you need.

2

Screens removed & washed

Screens come off and get individually washed and dried before reinstallation.

3

Frames, tracks & sills

We detail the parts most cleaners skip — tracks, sills, and frames — so the whole window looks new.

4

Water-fed pole & squeegee

We use both a water-fed pole system with deionized water and traditional squeegee cleaning — the right tool for each window. The deionized water dries spot-free with no water marks, and the pole reaches high windows safely from the ground.

Why It Matters

More than just a clean look

More light, better views

You'd be surprised how much film builds up gradually. Clean glass genuinely brightens interior rooms.

Protects your windows

Hard-water minerals and grime can permanently etch glass over time. Regular cleaning prevents costly replacement.

Catch problems early

We spot failing seals, cracked panes, and damaged screens while we work — before they become bigger issues.

FAQ

Common questions

Do you clean interior windows too?

Yes — interior cleaning is available alongside our exterior service. Choose exterior only, or have us do both. They're priced separately, so you only pay for what you need.

Can you remove hard water stains?

Light mineral spotting usually comes off with our standard process. Heavier etching may need a specialty mineral-removal treatment, which we can quote on inspection.

What if it rains right after?

Rain itself doesn't dirty clean glass as much as people think — it's dust and runoff. If results are affected shortly after a service, talk to us and we'll make it right.

How often should windows be cleaned?

Twice a year is the sweet spot for most homes — spring and fall keep glass clear year-round.
