The garage door seals you see on this website all have a few features in common, including:
•Stopping any water from making its way inside the garage
•Acting as a garage door water stop in case of flooding
•The seals help you keep heat in and overall reduce your electricity costs
•Allows you to spend less time cleaning the garage
•Keeps the garage clean by not letting any windswept debris in
•Prevents field mice and other rodents from sliding under the gap
•Stops leaves being blown under the garage door
How will your products help me?
Aside from the features above, there are other applications of the products that haven’t been listed out yet. Though our threshold seals were designed with commercial and domestic garage doors in mind that doesn’t mean you can’t use them, for example, to waterproof around a shower or basin in order to keep the water in. You can see on this video that it will stop the water from spilling over regardless.
This is what makes our products special, because while they may only have one purpose the quality of them speaks for itself. They not only protect your garage and premises from rainfall they also stop condensation and damp build up stopping the cause of rusting at the very source, they will take care of your equipment, tools, appliances, and any cardboard boxes you need for the future.


How does our product range work?
Our products are all designed and work in a very similar way with the only real difference being the sizes and how you apply the threshold seal. Our commercial door thresholds need to be bolted on to the floor after which they are fully secured and ready to protect your premises from the rain. Similarly, our garage door threshold seals need to be stuck onto the floor with an adhesive. The adhesive and sealant is provided with any of the garage door seal kits and after you have affixed it to the floor you also have a 5 year warranty to keep your garage clean and dry.
The way our garage door threshold seals work is that after you have successfully affixed them to the garage door and floor or roller shutter door and floor then a watertight seal is created. This then prevents any and all rainfall from getting into your premises and allows you to feel fully protected from the elements.
Each of our seals is made with environmentally friendly materials, using highly recyclable PVC plastic for the domestic range of products and aluminium for the commercial which is the most recyclable metal on the planet. When you buy with GaraDry® you are buying for the long term, with a 5-year warranty on our products and easily recyclable materials.
