Installing Vinyl Siding Over a Brick House | Home Guides

Vinyl siding must be applied over a smooth, level surface.

Vinyl siding can be applied over almost any existing exterior wall surface, as long as the surface is smooth and level. Installing siding over a brick wall, which is not smooth and level, requires a bit more work than installing the same siding on new construction. However, the installation process is still relatively straightforward.

Suitable Surfaces for Vinyl Installation

Vinyl siding must be applied over a smooth, even, watertight surface. Siding installed over an uneven surface is prone to rippling and bowing. Even in cases of new construction where the siding isn't being applied over existing cladding material, you can't apply the siding directly to the wall studs. You must apply a rigid sheathing material to the studs, then secure the siding to the sheathing. When you install siding over an existing brick, masonry or stucco wall, creating a level substrate for the siding is even more important. You need to first cover the brick with a layer of sheathing to which you'll attach the siding.

Furring Strips

The first step in creating a level surface for the siding is attaching vertical furring strips to the brick. You will secure the rigid sheathing to these vertical wood strips. Manufacturers such as CertainTeed and Alcoa Home Exteriors recommend that you use 1-by-3-inch furring strips and attach them to the masonry using ring-shanked nails, spacing the strips a minimum of 12 inches and no more than 16 inches apart on center.

Garage remodel

Hi all! Just stumbed upon CL's fixit forum for the first time and thought I would give it a shot.
I have a 10x18 attached garage that I want to turn into a family room. Garage is above grade, with concrete floor, and block and brick walls. Want two windows installed in brick as well as a new opening thru brick to the house. Garage door removed and framed in with a new 36" entry door and vinyl siding over where old garage door was. Baseboard heat is needed. Electric (just outlets) is needed (ample room in panel). Floor, walls and ceiling need to be studded out and drywalled...wood studs

    • As a professional it is not difficult however, it is very dusty and definitely not a one person job. Start with installing your 5/4 boards on the corners of the house. Then make sure your bottom board (the first one you …edge of the first board. I would make it 7" long and that will let you maintain the same space between each row. Set the next course on the top (the bottom of the "T") and nail. Keep going until your done.
