Garage threshold seals fitted properly - aluminium bars with rubber inserts fixed to floor. Stop water, draughts, and leaves coming in under the door.
Stop The Puddles
Every time it rains, water runs into the garage. Or there's a draught howling under the door. Or leaves blow in and you're constantly sweeping.
Threshold seal = dry, draught-free garage. Simple fix that makes a big difference.
💡 Pro tip: Threshold seals work way better than door-mounted seals on sloped or uneven garage floors. The adjustable rubber insert compensates for floor levels.
Why Threshold Seals Work Better
Especially for typical Devon garages with sloped floors:
| ✅ Threshold Seal | ❌ Door Bottom Seal |
|---|---|
| Adjusts to uneven floors | Gaps where floor slopes |
| Rubber insert replaceable | Whole seal needs replacing when worn |
| Fixed to floor (solid) | Fixed to door (moves, wears) |
| Works with drainage slope | Fights against slope |
The reality: Most Exeter garages have floor that slopes toward door for drainage. Threshold seals work with that, door seals fight it.

🔧 DIY Tips
Fitting a threshold seal yourself is doable with right tools:
🔧 Tools you'll need
- Drill with masonry bits
- Hacksaw or angle grinder (to cut seal to width)
- Wall plugs and screws (usually supplied)
- Tape measure
- Spirit level
- Safety glasses (concrete drilling is dusty)
📐 Measuring
- Door width - measure actual opening, not door itself
- Floor level - check if it slopes, note high/low points
- Rubber insert - how much adjustment you need
🔩 Installation
- Cut aluminium bar to exact width
- Position centrally under closed door
- Mark fixing holes on floor
- Drill holes in concrete (right size for plugs)
- Screw seal down firmly
- Adjust rubber insert until it contacts door evenly
⚠️ Common DIY mistakes
- Cutting seal too short (gaps at ends)
- Not drilling deep enough (screws won't tighten)
- Positioning too far forward/back (door won't close properly)
- Not adjusting rubber insert (doesn't seal)
- Skipping the cleaning step (seal doesn't stick/fix properly)
💡 Pro trick: Do a dry run before drilling. Position seal, close door onto it, check it's in right place and door closes properly. Only drill once you're certain positioning is right.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🔧 Sloped floors: If your garage floor has significant slope, threshold seals are really the only option that works. They have adjustable rubber that compensates for the slope.
Rubber insert replacement: When rubber wears out (usually 5-8 years), you just replace the rubber insert, not the whole seal. Keep the packaging so you know which insert to buy.
Drainage: Make sure seal doesn't trap water. If your garage floor slopes inward, water needs somewhere to go. Threshold seals usually have drainage slots but check they're not blocked.
Door clearance: Very occasionally, garage doors don't have enough ground clearance for a threshold seal. Check door has at least 15mm clearance when closed.
Color options: Most threshold seals come in silver/natural aluminium. Some available in brown or white if you want it to blend in.
Combined with door seal: For maximum draught/water exclusion, use both threshold seal on floor AND bottom seal on door. Bit overkill for most garages but if you're converting to habitable space, worth doing both.
Concrete quality: Really old or crumbling concrete might not hold the fixings well. I'll advise if your floor needs treating/repairing before seal can be fitted properly.
Frequently Asked Questions
What's the difference between door seal and threshold seal?
Door seal fixes to the door itself (rubber strip on bottom edge). Threshold seal fixes to the floor (aluminium bar with rubber insert). Both stop water/draughts but threshold seals work better on uneven floors.
Will it completely stop water coming in?
It'll stop rain blowing in under the door and significantly reduce water ingress. Won't stop flooding or serious water issues - that needs drainage work. But for normal rain and puddles, threshold seals work brilliantly.
Can you fit it on sloped garage floors?
Yeah - that's actually where threshold seals work best. The adjustable rubber insert compensates for floor slope. Much better than door-mounted seals on uneven floors.
Do I need to buy the seal first?
Better if you do - measure your garage door width and get appropriate length. But if you're not sure what you need, send me measurements and I'll advise. Most DIY shops and Screwfix stock standard sizes.
How long does a threshold seal last?
Quality ones last 8-10 years. Cheap ones maybe 3-5 years before the rubber perishes. Worth buying decent ones - only a few quid difference and you won't be replacing them as often.
