Our DIY roller garage doors are designed for homeowners in Lewisham who are confident in handling a self-installation project. That said, we don’t recommend tackling the job alone. The process is straightforward, but having a second person-especially during measuring and fitting-greatly improves accuracy and safety. For instance, when measuring the width of your garage opening, an extra set of hands can make all the difference in ensuring a precise fit.
On installation day, having two people is more than helpful-it’s crucial. Lifting, aligning, and securing the door in place requires coordination. Doing it solo isn't recommended. Most installations take around 4 to 6 hours using only basic tools like a drill, fixings, and a step ladder. To avoid interruptions, make sure all tools and parts are easily accessible before you begin. With our detailed instructions and video guides, you’ll have all the support you need to install your TWF garage door correctly and confidently.
Our measuring guide provides all the instructions you need. Alternatively, our DIY order form outlines each required measurement with visual examples. Simply click the “Garage Door Builder” button in the menu to get started.
