Streak-Free Windows: What Actually Matters

June 10, 20254 min read

Great windows aren't about a magic product. They're about three simple things done consistently — and that's where a professional visit is worth the money.

Purified Water

Water-fed pole systems use purified water so windows dry without mineral spotting. This is the same reason your home's tap water leaves marks.

Method And Timing

Direct sun and hot surfaces cause solutions to flash-dry, leaving streaks. A trained crew adjusts timing and technique to the conditions on your property.

Helpful Tips

Quick takeaways

  • Schedule after landscaping or exterior painting, not before.
  • Combine interior and exterior cleaning in one visit for the best result.
