Our 5-Step Process

From your first call to crystal-clear windows, here's exactly what to expect when you choose Apex Windows for your foggy glass replacement.

Step 130-45 minutes

Free Inspection & Estimate

It starts with a phone call or online request. We'll schedule a convenient time to visit your property and inspect every affected window. Our technician will measure each glass unit, assess the frame condition, and identify the exact type of insulated glass unit (IGU) needed. You'll receive a detailed written estimate on the spot — with no obligation and no pressure.

Step 25-7 business days

Custom Glass Fabrication

Once you approve the estimate, we order precision-cut insulated glass units built to your exact specifications. Each IGU is manufactured with two panes of glass separated by a spacer bar, filled with argon gas for superior insulation, and sealed with a dual-seal system. We can also add Low-E coatings for enhanced energy efficiency — especially beneficial in the Texas heat.

Scheduled Installation

When your custom glass units are ready, we'll call to schedule your installation at a time that works for you. Most residential jobs are completed in a single visit. We arrive on time, protect your floors and furniture, and get to work. There's no need to remove window treatments ahead of time — we handle everything.

Professional Installation

Our certified technicians carefully remove the failed glass unit from your existing frame — the frame stays in place. We clean the frame channel thoroughly, removing old sealant and debris. The new IGU is set into the frame with precision glazing points and professional-grade silicone sealant. Each window is tested for proper fit and seal integrity before we move on.

Common Questions

How do I know if my windows need glass replacement?
If you see fog, condensation, or a milky haze between the two panes of glass (not on the surface), the seal has failed and the insulated glass unit needs replacement. You can confirm by wiping both sides of the glass — if the fog remains, it's between the panes.
Will you need to remove my window frame?
No. We replace only the glass unit (IGU) inside your existing frame. The frame, trim, and exterior siding are never disturbed. This is what makes our process faster, cleaner, and more affordable than full window replacement.
How long does the entire process take?
From your initial call to completed installation, the typical timeline is 7-10 business days. The actual installation takes 30-60 minutes per window, and most homes are completed in a single visit.
Can you match my existing glass type?
Yes. We can match virtually any residential or commercial glass type, including tempered glass, Low-E coated glass, tinted glass, and specialty sizes. We'll identify the exact specifications during your free inspection.
