How to Trim an Outside Window With Wood
- 1). Put on eye protection, ear protection, gloves and respirator. Remove any old trim, using a crowbar and hammer to pull out any nails. Scrape away any remaining paint, wood, or dirt and grime, using a metal scraper.
- 2). Spray degreaser on the area and scrub with a steel-wool pad.
- 3). Set up your chop saw or skill saw. Have a table ready to place long pieces of trim on when you make your cuts.
- 4). Measure the width and height of each window if your old trim is damaged or rotten. If not, use the old trim as a template. Add on the measurement of the width of your trim boards and prepare to cut to size. Account for corner cuts made at a 45-degree angle. Use the chop saw or skill saw and table to cut each trim piece.
- 5). Attach each piece of window trim with a cordless drill and drywall screws, starting with one side. Use the level to position each trim piece carefully. You may use wood trim, plastic, or even architectural. Consult with a contractor to determine which kind of trim will last the longest in your area.
- 6). Cut off the end of the silicone tube at a 45-degree angle, using a utility knife. For large jobs, use a silicone gun and silicone cartridges. For one or two windows, use a small tube of silicone.
- 7). Apply silicone to the outside trim, forming a bead all the way around each window. Let dry overnight.
