What we see in Lewisville homes.
Lewisville has older neighborhoods around Old Town, a wave of homes from the 1980s and 90s, and newer areas like Castle Hills, so we see everything from original aluminum windows to tired builder-grade vinyl.
Original windows reaching the end of their life
Windows from Lewisville's 1970s–90s building boom often have failed seals (fogging between the panes), worn weatherstripping and clear glass with no Low-E coating, so west- and south-facing rooms run hot.
Attics that have settled
Blown-in insulation from that era has usually settled well below today's recommended depth. Topping it up is one of the lowest-cost ways to cut summer cooling bills.
Entry doors exposed to the afternoon sun
Wood and early steel doors on west-facing entries warp, fade and leak air. A fiberglass door holds its shape and insulates better.
