See How Easy It Is to Upgrade Your Windows

If you're looking for a reliable window replacement installer in Oklahoma, you've come to the right place. At 405 Windows, we’ve designed our process to be simple, transparent, and respectful of your time and your home.


Whether you need a full window replacement for your home or just a single window replacement, our team is committed to making the entire experience easy and stress-free.


Here’s how it works from start to finish — no guesswork, no gimmicks.

Step 1: Free In-Home Consultation

We start by sending one of our experienced team members to your home to discuss your window goals, answer your questions, and take precise measurements.


  • No sales pressure
  • No surprise fees
  • Just honest advice on what works best for your home and budget


If you’ve been Googling who replaces windows near me and getting overwhelmed, this first meeting is where things start to get real — and easy.


What We Cover During the Consultation:


  • Style and material preferences
  • Energy efficiency goals
  • Timing and budget
  • Any specific concerns (drafts, leaks, difficult openings, etc.)

We’ll leave you with a clear quote and plenty of options, and we’ll give you space to think it over without hounding you.

Step 2: Custom Ordering Your Windows

Once you approve your estimate, we custom order your windows to fit your exact specifications. Every window is made to order — we don’t pull generic sizes from a warehouse.


You can choose from:


  • Awning, casement, double-hung, single-hung, sliding, or custom shapes
  • Vinyl, wood, or composite frames
  • ENERGY STAR-certified glass options


Lead times vary depending on style and material, but we’ll keep you updated every step of the way.

Step 3: Scheduling Your Installation

Once your windows are delivered, we’ll reach out to schedule a convenient install date. Most window replacement and installation jobs can be done in a single day — even whole-home replacements.


We respect your time, so we show up when we say we will, ready to work. You don’t need to take a week off work or live in a construction zone.

Step 4: Installation Day – What to Expect

Here’s what happens when our installers arrive:



  • We prep the workspace by protecting floors and furniture
  • Old windows are removed cleanly and safely
  • New windows are installed and sealed to prevent drafts or leaks
  • Frames are insulated and exterior trims are secured
  • Work areas are fully cleaned
  • We walk you through the finished job


We don’t subcontract our work — your windows are installed by experienced professionals who care.

Step 5: Post-Install Support & Warranty

After installation, we’re still just a phone call away. Every window comes with a product warranty, and we back our labor with a satisfaction guarantee.


If you have a question, concern, or just want to double-check something — we’ll be there. That’s what makes us a trusted window replacement installer in Oklahoma.

FAQs About the Installation Process

  • Do I need to be home during installation?

    Not necessarily. As long as we have access and clear instructions, we can complete the job while you're out. Many homeowners work from home or run errands during installation.


  • What should I do to prepare my home?

    • Move furniture 2–3 feet away from windows
    • Take down curtains, blinds, or window coverings
    • Deactivate alarms or notify your alarm company in advance
    • Keep pets in a secure room

  • What happens to my old windows?

    We haul away and dispose of all old windows as part of our service. If you’d like to keep them, just let us know ahead of time.


  • What about cleanup?

    We clean up every work area thoroughly. That includes vacuuming debris, wiping down surfaces, and removing all packaging or materials.


  • What’s the warranty coverage?

    Most windows come with a manufacturer’s warranty ranging from 10 years to lifetime coverage. We also include a labor warranty on our installation.


Why We Don’t Do Repairs, Auto Glass, or Insurance Work

Our expertise is window replacement for homes — not repairs, not windshields, and not navigating insurance claims.


Here’s why:


  • Repairs often fail to address underlying issues like frame rot or air leaks
  • Auto glass and commercial glass require different tools and certifications
  • Insurance claim work often delays homeowners from getting what they need


Instead, we keep our focus on full, high-quality window replacement and installation that actually improves your home’s comfort, efficiency, and appearance.
