Expert Window Installation and Replacement
Serving Delaware County & Surrounding Areas
Comprehensive Window Installation & Replacement
Quality-driven craftsmanship tailored to your home
J.R.Peck Construction Group, LLC delivers full-service window installation, replacement, and repair for residential and light commercial properties. We offer premium vinyl, fiberglass, wood, and composite frames in every style—double-hung, casement, awning, slider, picture, bay and bow, egress, and custom shapes—to match your architecture and budget.
Our trained installers perform precise measurements, prepare openings, and integrate each unit with proper flashing, sill pans, shims, insulation foam, and drip caps for a watertight, air-sealed fit. We handle interior and exterior trim, caulking, and finishing, follow manufacturer specs, pull permits when required, and leave your space spotless.
Modern glazing, frames, and weatherproofing that save
Upgrade comfort and lower utility costs with modern glazing. Choose double- or triple-pane Low-E glass with argon or krypton gas fills, warm-edge spacers, and ENERGY STAR-certified packages tuned for our climate. We help you balance U-factor, SHGC, and visible transmittance to optimize efficiency and daylight.
Beyond efficiency, we offer performance options such as laminated or tempered safety glass, enhanced locks, and frames engineered for low air infiltration and high design pressure. Acoustic upgrades with higher STC/OITC ratings reduce street noise while UV-blocking coatings protect interiors from fading.
Transparent estimates and backed-by-warranty service
Our process starts with a consultation to assess existing openings, discuss goals, and present product options. You’ll receive a detailed, transparent proposal with scope, specifications, and timeline. Typical lead times range from 1–2 weeks for standard sizes to 3–6+ weeks for custom builds; installation includes careful protection of your home, removal and disposal of old units, and a thorough walkthrough.
Project pricing depends on window count and size, frame material, style, glass package, finishes, and site conditions like masonry cut-outs, structural repairs, or lead-safe procedures for homes built before 1978. We offer fair, itemized estimates, seasonal promotions, and flexible payment options to fit your budget.
All products come with strong manufacturer warranties and our workmanship warranty for added peace of mind. As a family-owned team, we stand behind our work with responsive service after the job and guidance on care and maintenance to keep your windows performing for decades.
