Sunrooms & Four-Season Rooms in Frontenac, Missouri

Frontenac homes and this kind of project

A four-season room in Frontenac means working in estate homes from mid-century to new, 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: estate homes on lots of an acre or more, from mid-century to new.

Steel-look windows, stone floors with radiant heat and vaulted timber ceilings are common.

Lots, exteriors and approvals in Frontenac

Covered terraces, pavilions and additions with close attention to the city's site and tree rules.

Additions to Frontenac homes must match demanding originals: brick and stone, steep roofs, custom windows. We source matching materials early, because a poor brick match on a house of this caliber is not acceptable.

What is included

For Frontenac 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 in and around estates off Clayton, Geyer and Spoede roads.

What we watch for

Existing Frontenac porch floors are often uninsulated decking over open air. Converting means building an insulated, sealed floor assembly, which affects finished floor height at the house door.

Working on acre-plus sites, as we do in Frontenac, we plan access for a foundation crew, framers, a roofer, a window installer, an HVAC tech and finishers before the first delivery arrives.

Permits and approvals in Frontenac

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

Exterior work in Frontenac can also involve the city's architectural review, and we put that package together for you.

Schedule and getting to you

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

Frontenac sits toward the edge of our range: down I-64 to Lindbergh, around forty minutes. We group trade visits and deliveries carefully for projects at that distance, and we take them on when the scope justifies a dedicated crew.

What moves the price in Frontenac

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

• Window count, size and quality.
• Foundation type and height above grade.

Our step-by-step method for this work, and the factors that move its price, are laid out on the main sunrooms & four-season rooms page. More about the area is on our Frontenac page.
