At Tekton Exteriors Mississippi, window and door replacement isn’t about swapping old for new—it’s about engineering a tighter, smarter, safer building envelope for Mississippi’s demanding climate. Our process starts with a forensic-level assessment: we inspect for frame deterioration, moisture intrusion behind trim, hardware fatigue, and seal failure—issues often invisible to homeowners but critical for long-term performance. For replacements, we primarily install Pella vinyl and fiberglass windows (400 Series and Lifestyle Series) and ProVia, Therma-Tru, and Pella entry/ patio doors, all selected for proven resilience in high-humidity, high-UV environments. Installation follows strict protocols: full-frame replacements when structural integrity is compromised (common after hail or water damage), or pocket installations for intact frames. We use closed-cell spray foam insulation at every seam—not just caulk—to block air infiltration, and apply integrated flashing systems compliant with the 2023 IRC and Mississippi wind-load requirements (130 mph in Rankin County). Our crews are manufacturer-trained and certified, ensuring every unit is level, plumb, and anchored to resist wind uplift. Even seemingly minor details matter: we specify stainless steel hardware to prevent rust, weathertight sill pans to channel water away, and low-conductivity spacers to minimize thermal bridging. This meticulous approach ensures your new windows and doors perform for decades—not just until the next storm.
