Your Home Deserves Better Windows – Let’s Replace Them the Right Way

At 405 Windows, we offer expert home window replacement throughout Oklahoma City and surrounding areas. Whether you need one window replaced or a full-home upgrade, we bring the same level of quality, transparency, and care to every job.



We specialize in full-frame residential window replacement, which means removing the entire window unit — frame and all — and installing a brand-new, energy-efficient window that fits perfectly and performs for decades.

What We Do (and Don’t Do)

Not all window companies are created equal. At 405 Windows, we make it clear up front what we do and what we don’t:

✅ We Do:


  • Full-unit home window replacement
  • High-performance ENERGY STAR-certified window installs
  • Custom options: awning, casement, sliding, double-hung, single-hung
  • Service for homeowners only — no commercial, no rentals


❌ We Don’t Do:


  • Glass-only repairs
  • Windshield or car windows
  • Commercial window replacement
  • Insurance claims or third-party lead aggregators


We’re not trying to be everything to everyone — we just want to be the best at residential window replacement in Oklahoma City.

    We come to you, assess your needs, measure your windows, and walk you through your options. No pressure. No confusing jargon.

  • 2. Custom Orders & Transparent Pricing

    Once you’ve chosen your window style and material, we place your custom order. You’ll get an honest quote with no hidden fees or surprise upsells.

    All our work is backed by warranties and follow-up support. If there’s ever a question, you’ll speak directly with someone local — not a call center.

Why Energy Efficiency Matters

Upgrading to ENERGY STAR-certified windows can dramatically improve your home’s comfort, value, and energy bills. Here’s how:



  • Improved insulation means fewer drafts and better temperature control
  • UV-blocking glass reduces fading of floors and furniture
  • Lower energy bills all year long
  • Better noise reduction from outside sources


We’ll walk you through the best energy-efficient windows for Oklahoma homes, including U-factor ratings, materials, and what actually matters for your property.
