A Guide to Siding Corners

As home builders, it’s critical to find ways to deliver top-tier building solutions for your clients while remaining efficient. This helps you finish current jobs with excellence and move on quickly to tackle your next job. While it’s inevitable that some parts of the siding process require a little more time or attention to detail, LP Building Solutions offers durable, time-saving products such as LP® SmartSide® ExpertFinish® Outside Corners that help improve efficiency while contributing to curb appeal. 

How Do You Install Corners on Wood Siding?

Typically, to create siding corners builders have to measure, cut and fasten together two pieces of trim to meet at the corner of a house. While it can certainly be done, ensuring a clean look by getting exact measurements can be tedious and time-consuming. 

Knowing how to install wood siding corners with trim is important when it’s what you have on hand, but if you’re looking for a time-saving solution pre-assembled siding corners are a great jobsite hack. LP SmartSide ExpertFinish Outside Corners are one-piece pre-assembled siding corners that come prefinished to match LP® SmartSide® ExpertFinish® Trim & Siding products. By eliminating the need to measure and fasten two pieces of trim together, outside corners help you get the job done faster while creating a cleaner look at the corner. 

Here are some quick installation tips to keep in mind:

  • Outside corners can be installed to wood structural panel wall sheathing or directly over wood, wood composite or fiber cement siding
  • Outside corner trim applied adjacent to surfaces such as porches, patios, balconies, walking surfaces or porch columns must have a clearance of at least 1 inch (25 mm) above any horizontal surface
  • Where edges of trim meet siding material, windows, doors or other finished openings, leave a minimum 3/16 inch (5 mm) space to allow for proper sealant/caulking
