What we see on Florissant homes
The median house in Florissant was built in 1963, and 76.7% of the housing stock there predates 1970. 23,221 housing units, 66.5% of the occupied ones owner-occupied. That leaves a real share of rented property, and a landlord asks different questions than an owner: what fails soonest, what a tenant will call about. The quote is the same either way. Only 1.4% predates 1940, so most of what we take out here is a replacement unit somebody already fitted once, and how well that was done decides how much of the opening we rebuild.
The exterior on a house that age is often not the first one. Aluminum siding from the sixties, vinyl over the top of it in the nineties, and somewhere underneath the wood the house was built with. We look behind the old material before quoting, so the layer count and the state of the sheathing are known rather than guessed at. In these houses the original single-glazed windows are usually the biggest single draft in the place. On windows specifically the number that matters is how many openings are actually costing you. We will quote the worst room on its own if that is the sensible place to start.

Permits and paperwork in Florissant
Permits for work like this in Florissant come from City of Florissant Building Division. Some jobs need one and some do not. We work out which yours is at the consultation, not after the tear-off has started, and we pull it ourselves.
We are licensed and insured. Missouri has no statewide roofing license, because roofing is licensed city by city here, so an Illinois license number would carry no weight on this side of the river and we do not quote one at you. Ask for the certificate and you will have it.
Where we work from, and what is nearby
Florissant, MO sits in St. Louis County, and we serve it from our Greater St. Louis office at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303.

What we can put on a Florissant house
Elite Pro and Elite Pro Plus+ windows: vinyl frames, energy-efficient glass, and the full range of shapes: double-hung, casement, awning, slider, bay and bow, picture, garden and geometric. Interior woodgrains and UV-resistant exterior colors, grids in colonial, prairie or perimeter prairie, and obscure or rain glass where a bathroom or a street-facing window needs it. Every unit is measured to your opening rather than ordered as a size.
There is a showroom at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303. Most people change their mind about a color at least once standing in front of the full-size panel, which is a much cheaper place to do it.
