High-Performance Window and Door Solutions
Serving Long Island & Surrounding Areas
Full-Service Installation and Replacement
Precision craftsmanship for lasting performance
Msquared Construction Corp provides turnkey window and door services, from consultation and design through product sourcing and professional installation. We evaluate your openings, measure precisely, recommend the best materials and brands for your goals, and coordinate timelines to minimize disruption while delivering superior fit and finish.
Our installers follow industry best practices, including ASTM E2112 water management and AAMA installation guidelines. We integrate sloped sill pans and back dams, apply premium flashing tapes, set units plumb, level, and square, insulate with low-expansion foam, and seal exterior joints for durable, leak-free results. We calibrate hardware, verify operation, and leave each workspace clean.
Advanced materials that lower utility costs
Choose high-performance glass packages such as double- or triple-pane, Low-E coatings, argon or krypton gas fills, and warm-edge spacers to reduce heat transfer and glare. Frame options including fiberglass, composite, vinyl, aluminum-clad, and wood-clad deliver strong thermal breaks, low air infiltration, and excellent acoustic performance to quiet outdoor noise.
We help you interpret NFRC labels and select U-factor and SHGC targets suited to your home’s orientation. Safety and code needs are addressed with tempered glass in hazardous locations, egress-compliant bedroom windows, impact- or DP/PG-rated assemblies where required, and ADA-friendly threshold options. We manage permits, follow EPA RRP lead-safe practices in pre-1978 homes, and coordinate inspections.
Tailored aesthetics and everyday functionality
Window styles include double-hung for classic ventilation, casement and awning for superior sealing, sliders for space savings, picture for unobstructed views, and bay or bow units to add dimension. Specialty shapes, garden windows, and basement hoppers address unique design needs while maintaining performance.
Door solutions span secure entry systems in fiberglass, steel, or premium wood; sliding and French patio doors for indoor-outdoor flow; and multi-slide or bi-fold panels that open wide for entertaining. Options like integrated blinds between the glass, retractable screens, and multi-point locking enhance convenience, airflow, and security.
Finish and hardware selections complete the look: factory paint or stain, durable capstock or anodized cladding, and hardware in popular finishes. Grille patterns, divided-lite styles, tinted or privacy glass, and smart locks with sensor integration let you personalize performance, maintenance needs, and curb appeal.
