What we see on Wentzville homes
The median house in Wentzville went up in 2007, and 88.9% of the town was built from 1990 onward. 15,919 housing units, 84.6% of the occupied ones owner-occupied. That is a high share, and it means most of these conversations are with the person who will live with the result rather than with somebody signing off on a property they never see. 38.7% has gone up since 2010: builder-grade units in houses that have now settled, which is why the complaint is usually a draft or a failed seal rather than rot.
Houses built after 1990 came with vinyl siding and double-glazed windows from new, so this is rarely a rescue job. It is a replacement at the end of service life, and that changes what is worth doing. The wall system behind is usually sound, which moves the decision away from repair and onto material and profile: Alside vinyl, or Ascend Composite if you want the look of real wood. 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 Wentzville
Permits for work like this in Wentzville come from City of Wentzville 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is licensed city by city here, so an Illinois license number would carry no weight on this side of the river and we do not quote one at you.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.

Wentzville, MO sits in St. Charles County, and we serve it from our Greater St. Louis office at 2424 Hwy 94 S. Outer Rd., St. Charles, MO 63303.
In Wentzville that covers 63385. Being outside our published list does not mean we cannot come, so call and we will tell you straight away.
What we can put on a Wentzville 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.
