Chester County Sunroom Addition Ideas and Services

MCG Contracting offers a various number of sunroom types.  From patio enclosures to three season sunrooms and even four season sunrooms, our expertise cannot be matched. The following sections detail our sunroom addition types.

Three Season Sunrooms

Three season sunrooms are enclosed additions which are generally composed mostly of windows from the floor to the ceiling along with a door or two for entry to the exterior and interior of the home. Referred to as three seasons sunrooms, because they are generally not established with any heat or air conditioning dedicated to the space, meaning they are mostly usable for spring, summer and fall seasons.  Three of the four seasons! Clients will often enclose an existing covered patio or porch to control bugs and allow the room to be finished with carpet and higher end finishes. Depending on the size, opening doors to the interior of the home can often help regulate humidity and temperature for most of the year.

Four Season Sunrooms

Similar to a three season room, the four season room is an enclosed addition to the home, however, the space is built to be insulated and designed to be tied into HVAC systems so that it can be cooled and heated year round based on the season. A four season sunroom is still mostly made of windows to provide vast, open views to the outside, but some space may need to be dedicated to running ductwork in walls, floors or ceilings.  These types of sunroom additions truly add to the footprint of the home and can be better integrated, potentially even as a fully open space connected back to the interior requiring no door between the home and four season room.

Patio Enclosures

Patio enclosures tend to be the easiest and most cost effective type of sunroom addition. Most often, patio enclosures are built on top of existing patio foundations (hence the name patio enclosures) which will connect an existing overhead roof or add a roofing structure over the space. Lead time tends to be less as the structure requires less architectural design and permits tend to be easier to approve within most townships as long as the existing foundation is deemed adequate. Foundations can be an assortment of materials, including brick, concrete, pavers and more. Patio enclosures may or may not be screened in, leaving the choice to the home owner whether they wish to keep out bugs, dirt and other items or if they want to leave the space open allowing access to the outside from all directions of the enclosure.
