Preparing Basement Walls for Siding Installation

Proper preparation is essential for a successful siding installation. Before you begin installing any siding, you need to thoroughly inspect and prepare your basement walls. This involves addressing any existing moisture problems, repairing cracks or damage, and ensuring a clean and level surface.

Addressing Moisture Problems

Moisture is the biggest enemy of basements. Before installing siding, it’s crucial to identify and address any existing moisture problems. Look for signs of water damage, such as stains, mold, or efflorescence (a white, powdery deposit on the walls). Common causes of basement moisture include:

• Poor Drainage: Improperly sloped landscaping or clogged gutters can cause water to pool around the foundation and seep into the basement.
• Cracks in the Foundation: Cracks in the foundation walls or floor can allow water to enter the basement.
• High Water Table: A high water table can put constant pressure on the foundation, forcing water through the walls and floor.
• Lack of Waterproofing: If your basement walls are not properly waterproofed, they will be susceptible to moisture intrusion.

To address moisture problems, you may need to take the following steps:

• Improve Drainage: Ensure that your landscaping slopes away from the foundation and that your gutters are clean and functioning properly.
• Repair Cracks: Seal any cracks in the foundation walls or floor with a waterproof sealant.
• Install a Drainage System: Consider installing an interior or exterior drainage system to collect and divert water away from the foundation.
• Waterproof the Walls: Apply a waterproof coating to the interior or exterior of the basement walls.
• Install a Dehumidifier: A dehumidifier can help to reduce moisture levels in the basement air.

Cleaning and Repairing Walls

Once you’ve addressed any moisture problems, you need to clean and repair your basement walls. This involves removing any dirt, debris, or loose paint and filling any cracks or holes. Use a wire brush to scrub the walls and remove any loose material. Fill any cracks or holes with a concrete patching compound and allow it to dry completely before proceeding.

Installing Furring Strips

Furring strips are thin strips of wood or metal that are attached to the basement walls to create a level surface for the siding. They also provide an air gap between the siding and the wall, which can help to improve ventilation and prevent moisture buildup. Furring strips should be installed vertically, spaced 16 to 24 inches apart. Use a level to ensure that the furring strips are straight and aligned. Attach the furring strips to the walls with concrete screws or nails.

Installing the Starter Strip

The starter strip is a metal or plastic strip that is installed along the bottom of the wall to provide a base for the first row of siding. It should be installed level and securely fastened to the furring strips. The starter strip is crucial for ensuring that the siding is properly aligned and that the bottom edge is protected from moisture.

Installing the First Row of Siding

The first row of siding is the most important because it sets the tone for the entire project. Start by aligning the bottom edge of the siding with the top of the starter strip. Secure the siding to the furring strips with nails or screws, following the manufacturer’s instructions for spacing. Ensure that the siding is level and that the seams are properly aligned.

Overlapping and Securing Subsequent Rows

Subsequent rows of siding should overlap the previous row by the amount specified by the manufacturer. This overlap creates a waterproof seal and prevents water from penetrating behind the siding. Secure each row of siding to the furring strips with nails or screws, ensuring that the fasteners are properly spaced and that the siding is level. Stagger the seams between rows to prevent a continuous vertical line.

Cutting and Fitting Siding Around Obstacles

You will likely need to cut and fit the siding around obstacles such as windows, doors, and pipes. Use a saw or utility knife to cut the siding to the appropriate size and shape. Be sure to leave a small gap around the obstacle to allow for expansion and contraction. Caulk the gap to prevent water from entering.

Finishing Touches
