Siding in St. Louis.
Siding is the jacket your house wears against St. Louis weather. Among the siding companies St. Louis MO homeowners have trusted since 1953, we install siding that seals out water, cuts maintenance to almost nothing, and changes the look of the whole exterior in a single job.
A new look that protects.
We have been improving St. Louis exteriors since 1953, and siding is one of the biggest changes you can make. It refreshes the curb appeal of the whole house and, done right, seals the walls against water and weather for years with almost no upkeep. We measure, quote, and install with our own crews, and we handle siding repair too, so damaged or worn sections can be fixed without redoing the whole exterior.
Protects the whole house
Properly installed siding keeps water off the structure and out of the walls, which is the quiet job that matters most.
Almost no upkeep
No more scraping and repainting every few seasons. New siding holds its color and sheds the weather year after year.
Pairs with your windows
Doing siding and windows together means one clean, sealed exterior, detailed at every opening by the same crew.

Siding questions we hear a lot.
Does new siding protect my house or just change the look?
It does both. Properly installed siding keeps water off the structure and out of the walls, which is the quiet job that matters most, and it refreshes the curb appeal of the whole exterior in a single job. We detail every opening as we go so the walls are sealed against St. Louis weather for years with almost no upkeep.
Is new siding low maintenance?
Yes. New siding ends the cycle of scraping and repainting every few seasons; it holds its color and sheds the weather year after year. That low upkeep, plus a sealed exterior that keeps water out of the walls, is why siding is one of the biggest single improvements a St. Louis homeowner can make.
Can you do siding and windows together?
Yes, and it is often the smart way to do it. Replacing siding and windows in one project means one clean, sealed exterior, detailed at every opening by the same crew, instead of two separate jobs that have to be tied together later. We measure, quote, and install both with our own installers.
Do you repair siding, or only install it?
We do both. If a section of siding is damaged or worn, we can often repair it rather than redo the whole exterior, and we handle siding repair across the St. Louis metro, including Chesterfield and the rest of West County. If the exterior is past patching, we will say so and give you a straight price on replacement, with a free estimate either way.
