A wet garage floor is one of the most common issues faced by homeowners across Edinburgh, Fife, Falkirk, Dundee, Perth, Stirling, Livingston, Angus, the Scottish Borders, St Andrews, East Lothian, West Lothian, Tayside, Dunfermline, and East Central Scotland. Heavy rain and uneven driveways often cause water to seep under garage doors, leaving behind puddles, dampness, and even long-term structural damage if left untreated.
One of the simplest and most effective solutions is fitting a garage door bottom seal. In this guide, we’ll explain why leaks occur, how seals work, and the process of installing one—plus when it’s best to call in a professional.
Why Does Water Leak Under Garage Doors?
Water ingress beneath garage doors usually happens due to:
Worn or missing seals – Over time, rubber seals harden, crack, or shrink, losing their effectiveness.
Uneven garage floors or driveways – Small dips or slopes allow rainwater to run directly toward the door.
Poor drainage – Blocked drains or inadequate run-off channels increase pooling around the entrance.
Ageing garage doors – Older models may not close flush with the ground.
In areas such as St Andrews or the Scottish Borders, where heavy rainfall is common, these issues can quickly escalate if not addressed.
What Is a Garage Door Bottom Seal?
A garage door bottom seal is a strip of durable rubber or vinyl that attaches to the underside of your door. Its purpose is to create a watertight barrier between the door and the ground, preventing water, debris, pests, and draughts from entering.
Modern seals also add insulation, making them a smart choice for homeowners in East Lothian, West Lothian, and Tayside, where cold winds and rain are frequent.
How to Install a Garage Door Bottom Seal
If you’re a confident DIYer, you may be able to install a bottom seal yourself. Here’s a step-by-step overview:
Measure the Door Width – Ensure you purchase the correct length of seal for your garage door.
Remove the Old Seal – If an existing seal is present, slide it out of the retainer track. Clean away dirt and debris.
Prepare the New Seal – Lubricate the grooves with a mild soap solution to make installation smoother.
Fit the Seal – Insert the T-shaped edges of the seal into the retainer track and slide it across.
Trim Excess – Cut off any extra length and check the seal sits evenly across the bottom of the door.
Test the Fit – Close the garage door and pour a small amount of water outside. If the seal is fitted correctly, no water should pass through
When to Call a Professional
While installation may seem simple, not every garage door is designed for easy seal replacement. Some older models in Dunfermline, Stirling, and Perth may require retrofitted tracks or adjustments to ensure a proper fit.
If your garage door is misaligned, dented, or damaged, a new seal alone won’t fix the problem. In such cases, it’s best to consult an expert in garage door repair to assess the wider issue.
For homeowners across Edinburgh, Fife, and East Central Scotland, professional fitting ensures your garage door remains fully weatherproof and secure.
Other Ways to Stop Water Ingress
While a bottom seal is highly effective, sometimes additional measures are needed:
Threshold seals – Raised strips fixed to the floor to block water flow.
Improved drainage – Installing drains or channels to redirect rainwater.
Garage door servicing – Adjustments to ensure the door closes evenly against the floor.

Long-Term Benefits of Sealing Your Garage Door
Installing a bottom seal not only prevents water leaks but also:
Protects flooring and stored items from damp damage.
Keeps pests and insects out.
Improves insulation and energy efficiency.
Extends the lifespan of your garage door.
For homeowners in Angus, East Lothian, and West Lothian, these small improvements can save hundreds of pounds in future repair costs.
