Expert Double-Hung Window Installation in St. Louis, MO

Double-hung window installation gives Franklin County homeowners two operable sashes that slide up and down independently. That design lets you open the top sash to push warm air out while pulling cooler air in through the bottom, which matters during the area's hot, dry summers. It also works in reverse during cooler months to manage indoor temperatures without running your system harder than needed. Both sashes tilt inward, so you can clean the exterior glass from inside your home without a ladder. That is a real advantage for two-story homes in Franklin County where exterior access can be awkward. Washington State Energy Code sets a maximum U-value for replacement windows, and proper installation is what makes those performance numbers real in your home. Lamb Contracting LLC serves homeowners across Franklin County and surrounding areas including Union, Pacific, Eureka, Fenton, St. Louis, and Sullivan in Missouri. If your current windows are drafty, hard to open, or letting heat escape, a double-hung installation is a practical fix. Contact us to get started.

Double-Hung Window Installation FAQ

Common questions about double-hung window installation in St. Louis, MO.

Yes, Lamb Contracting LLC installs double-hung windows for homeowners throughout Franklin County, Washington. We also serve surrounding areas including Union, Pacific, Eureka, Fenton, St. Louis, and Sullivan in Missouri.

A double-hung window has two sashes that both move up and down, while a single-hung window only opens from the bottom. That means better airflow and easier cleaning for Franklin County homeowners.

Both sashes tilt inward so you can clean the exterior glass from inside your home. This is especially useful for upper-floor windows in Franklin County where using a ladder outside is not always safe or practical.

Yes, you can open only the top sash for ventilation while keeping the bottom sash closed, which lowers the risk of a child or pet pushing through a screen. Many Franklin County families choose this style for that reason.

When installed correctly with proper sealing, double-hung windows reduce air leakage that drives up heating and cooling costs. Washington State Energy Code also sets a U-value standard for replacement windows, and professional installation is what makes that standard count.

Yes, we install double-hung windows in Union, Pacific, Eureka, Fenton, St. Louis, and Sullivan in Missouri as well. Contact us to confirm service availability for your specific location.

These guys have built a fence for our courtyard and put some much needed tlc into our well house. Tearing out drywall and installing a vent, etc...best thing about these fellas, they love Jesus! Looking for a solid Christian company to do buisness with, look no further.

Lamb contracting did an amazing job installing new metal door and screen door in our restaurant. They were priced great, and had it installed quickly. Will definitely be using them in the future.

Had Aaron and his team put a window in my mobile home. They did an amazing job! If you need a window put in or any other work get ahold of them!

Colby King Google review · September 2026

We are extremely pleased with the total bathroom remodel done by Aaron and his team. During the demo he found more work needed to be done than expected, but completed the job with amazing results. He is very honest and hardworking.
