Cornerstone Home Improvements is a trusted Window installation service, Contractor, Door shop, Door supplier, and Siding contractor serving homeowners with energy-efficient upgrades and custom installations. Schedule a free in-home consultation to get precise measurements, discuss goals like draft reduction or noise control, and compare materials (vinyl, fiberglass, wood) and glass options (low‑E, argon). Ask for a written, itemized quote and clarify warranties on labor and products, lead times, and whether they recommend full-frame or pocket replacements—then review recent project photos for quality. If you’re shopping doors or siding, visit their Door shop to test hardware and finishes, confirm which brands they’re an authorized Door supplier for, and inquire about financing or seasonal promotions to stretch your budget.
