Sunrooms & Four-Season Rooms in St. Peters, Missouri

St. Peters homes and this kind of project

A four-season room in St. Peters means working in ranches, split-foyers and two-stories from the 1970s to 1990s, so on our first visit we look at which way the room will face, the structure of any porch being converted and how it will be heated and cooled.

The housing stock here: 1970s to 1990s ranches, split-foyers and two-stories, with brick fronts and siding on the other three sides.

Many homes of this era have a deck or screened porch ready to be rebuilt as conditioned space.

Lots, exteriors and approvals in St. Peters

Mature trees mean shaded decks that stay damp and grow mildew, so composite does well here. Wood siding and trim on older homes need rot repair before painting. Patio covers and screened porches fit the deep rear yards.

Subdivision lots in St. Peters have defined building lines and easements, and HOA indentures that may be decades old but still binding. Most additions go to the rear. Matching vinyl or hardboard siding that is no longer made sometimes means re-siding a whole elevation.

What is included

For St. Peters porch conversions we begin with a structural check of footings, floor framing and roof, then detail the insulation and air sealing needed to make the room comfortable year-round.

We take on four-season room work across St. Peters, from Spencer Creek neighborhoods to Old Town St. Peters and Ohmes Farm.

What we watch for

West-facing sunrooms in St. Peters overheat without the right glass coating and some exterior shading. We select glazing by orientation rather than using one window for every wall.

St. Peters properties tend to be mature, tree-shaded lots, and that affects how we stage materials, where a foundation crew, framers, a roofer, a window installer, an HVAC tech and finishers park and how debris leaves the site.

Permits and approvals in St. Peters

In St. Peters, a four-season room is reviewed by the City of St. Peters. What follows is full addition inspections including energy code.

Since this work shows from outside, also plan on older subdivision indentures that are still in force. We prepare that submittal alongside the permit.

Schedule and getting to you

Plan on six to ten weeks of site work for a four-season room in St. Peters, once permits and materials are in hand.

St. Peters is a little over twenty minutes east on I-70 from our Wentzville base. We plan crew days and deliveries around that drive so you get full working days on site.

What moves the price in St. Peters

We price sunrooms & four-season rooms in St. Peters from a site visit, not a square-foot figure. These are the items that change the number.

• HVAC approach.
• Window count, size and quality.
