Window Installation done right, built to last
Properly installed, energy-efficient windows that improve insulation, ventilation, natural light, and comfort.
At Falc-Lion General Construction, every window installation project starts with a detailed on-site assessment and a clear, itemized plan — no surprises, no hidden costs. Our licensed crews work exclusively with materials proven to withstand New England’s freeze-thaw cycles, heavy snow loads, and coastal humidity, and every job is backed by our workmanship guarantee.
Serving homeowners across Vermont and New Hampshire, we combine 20+ years of local experience with same-week scheduling and transparent communication from first call to final walkthrough.
