Finishing Trim
Our Finishing Trim provides a sleek, seamless aesthetic to your garage door installation, ensuring every detail looks clean and well-defined. Designed to cover any visible gaps or joints, it creates a smooth, uniform frame around your door for a truly professional finish. Not only does this enhance the overall look of your garage, but it also adds to your home’s kerb appeal by giving the entrance a tidy, well-maintained appearance. Crafted for durability and long-lasting performance, our trim is the ideal way to refine your installation and elevate the look of your property.

Threshold Seals
Designed to create a consistent, tight seal between the bottom of your garage door and floor, our Threshold Seals provide effective protection against rainwater, leaves, dust, and other debris. By preventing moisture from entering, they help reduce the risk of damp, corrosion, and damage to stored belongings, keeping your garage cleaner and better protected all year round. Installed by our skilled garage fitters, our durable threshold seals deliver a practical upgrade that enhances both the performance and longevity of your garage space and are highly recommended for slightly uneven floors.

Why add Finishing Trim to your garage?
Finishing trim is fitted around your garage door frame to create a clean, seamless appearance. It covers small gaps or imperfections which could be left behind by previous door fittings, completing your installation with a sleek, modern look.

Why add a threshold seal to your garage?
A threshold seal is a simple yet highly effective upgrade that can make a big difference to the comfort and protection of your garage. Installed along the floor of your garage opening, it creates a secure, watertight barrier between the door and the floor when your door is closed.
Threshold seals help to keep out rainwater, leaves, dust, and debris, making your garage cleaner and drier all year round. They’re especially useful if your garage floor is slightly uneven, as they help to close the small gaps where water or drafts might otherwise enter.
By adding a threshold seal during installation, you not only improve the weather resistance of your garage but also help protect vehicles, tools, and stored belongings from damp or damage. It’s a small finishing touch that delivers lasting benefits in performance, cleanliness, and peace of mind.
