The QuickTrim System (QTS) is being used by contractors everywhere. As with any new product, there are questions on the best way to install it. Here are a few tips we’ve compiled to make using QuickTrim System for window surrounds a breeze:

Always glue/fasten corners before nailing the flange: When using QTS, you should always glue your corners BEFORE fastening the nailing flange. The attached starter strips will hold the board in place, making it easy for you to make a flush corner. This avoids any `tipping’ of the board. You can use any glue for PVC – we like using the Loctite ‘Professional’ glue as it dries in under 10 seconds.

Installing around windows: There are many methods to installing QTS around windows. We like to cut the 4 sides to size first and then glue 3 sides on the ground. This allows you to get better seams. You would then slide the 3-sided surround around the window, saving the fourth side to be glued at the window. Always fasten the nailing flange last.

When a J-channel is required for the siding, you’ll want to cut your corners at a 45-degree angle. This allows the J to be continuous around the window. If you’re not using a J-channel, you can butt the boards. It’s a good idea to seal the ends of any PVC with a small amount of Acetone.

Applying a Historic Sill: You’ll want to glue the corners of the head and legs first, prior to installing the sill. If the siding requires a J-Channel, you’ll have to cut a ¾” x ¾” notch on the sides of the sill. Once the head and legs are on the window, make sure the nailing flange is not fastened, glue the sill to the bottom of the legs. Once the sill is firmly attached, fasten the nailing flange around the window.
