Replacement Windows
Professional Window Installation Process
Window performance depends on installation. Even a premium replacement window can underperform if the opening is not prepared correctly, the frame is not leveled, or the sealing system is incomplete. At SunTek Exteriors, our installation process is designed to protect your home, improve long-term durability, and help every SOLR window system perform as intended.
Why Professional Window Installation Matters
A replacement window is only as strong as the installation behind it. Poor installation can lead to air leaks, water intrusion, uneven operation, reduced energy efficiency, and premature wear on locks and sash components.
That is why SunTek follows a structured installation process built around opening preparation, weather sealing, insulation, and final quality verification. This process supports long-term performance across our SOLR 3000, SOLR 7000, and SOLR 9000 window systems.

The SunTek Window Installation Process
1. Custom Window Preparation
Every opening is measured and verified before installation day. This helps ensure the replacement unit is manufactured to the correct dimensions and allows our team to plan any trim, sill, or structural considerations in advance.
2. Protect Your Home & Work Area
Before removal begins, our installation team protects surrounding floors, furniture, landscaping, and adjacent finishes. Dust control, drop cloths, and careful work-area setup help maintain a cleaner and safer installation environment.
3. Careful Window Removal
The existing window is removed carefully to minimize disruption to surrounding trim, drywall, siding, and exterior cladding. This step is critical for preserving the opening and reducing unnecessary repair work.
4. Opening Inspection & Preparation
Once the old unit is removed, the rough opening is inspected for moisture issues, wood damage, insulation gaps, and leveling concerns. If any repair or adjustment is needed, it is addressed before the new window is installed.
5. Precision Installation & Sealing
The new replacement window is placed, leveled, squared, and shimmed for proper operation. Our team then completes insulation, perimeter sealing, exterior weatherproofing, and trim finishing to help support energy efficiency and water resistance.
6. Final Inspection & Cleanup
After installation, every unit is tested for smooth operation, locking alignment, seal integrity, and finish quality. The work area is fully cleaned, old materials are removed, and the homeowner is walked through the completed installation.
