Siding starter strips are horizontal elements that are installed at the bottom of a wall to support the initial row of siding panels. They provide stability, create a straight edge, and protect the wall from moisture infiltration. As the name suggests, starter strips lay the foundation for the rest of the siding installation process.
Standard Guidelines for Installing Siding Starter Strips:
1. Suitable Material Selection:
Choosing the right material for siding starter strips is crucial in ensuring a durable and long-lasting installation. Common materials include wood, vinyl, fiber cement, and aluminum. Each material has its advantages and disadvantages, so it is important to consider factors such as climate, maintenance requirements, and cost before making a decision.
2. Proper Sizing:
Siding starter strips should be carefully measured and cut to the appropriate size. They should be long enough to span the entire length of the wall, including any corners, but short enough to create a small gap of around 1/8 inch between the strip and the corner post. This gap allows for expansion and contraction of the materials due to temperature fluctuations.
3. Correct Alignment:
Alignment is key to achieving a professional-looking siding installation. When installing siding starter strips, they should be positioned parallel to the ground and perfectly level. Using a level tool can help ensure accurate alignment. Proper alignment is crucial not only for aesthetic purposes but also for maintaining the integrity of the siding panels.
4. Secure Fastening:
Siding starter strips must be securely fastened to the wall to provide a stable base for the siding. Depending on the material, this can be achieved through various methods such as nails, screws, or adhesives. It is important to follow manufacturer recommendations and local building codes regarding the type and size of fasteners to be used.
5. Proper Flashing:
Flashing is an essential component when installing siding starter strips. It helps protect against water infiltration and redirects moisture away from vulnerable areas of the wall. Flashing should be installed behind the starter strip, extending at least 1 inch from the bottom of the strip and overlapping onto the top of the underlying moisture barrier or sheathing.
6. Consideration of Weather Exposure:
Exterior siding is exposed to various weather conditions, so it is important to consider the level of exposure when installing the starter strips. In areas prone to high wind or intense sun, it may be necessary to select starter strips with higher wind and UV resistance. Local building codes or manufacturer recommendations can provide guidance on the suitable level of weather resistance required.
7. Following Manufacturer Instructions:
While the aforementioned guidelines are fundamental, it is essential to consult the specific installation instructions provided by the manufacturer of the siding starter strips. Manufacturers may have additional requirements or recommendations that must be followed to maintain warranty coverage and ensure proper installation.
Proper installation of siding starter strips is a critical step in achieving a successful siding project. By adhering to the standard guidelines outlined above, homeowners can ensure a secure, level, and aesthetically pleasing base for the siding. It is always advisable to consult with professionals or manufacturers when in doubt, as they can provide expert guidance tailored to specific circumstances. The investment in a high-quality siding installation will undoubtedly enhance the beauty and protection of your home for years to come.
