Is Sealing a Waste of Money? Or Does It Actually Protect Your Driveway or Patio?
When it comes to keeping your driveway or patio looking great and lasting longer, sealing is one of those services people often question. Is it really worth it, or just another upsell?
The truth? When done correctly and on the right surfaces, sealing can make a big difference to how your outdoor spaces perform and look over time. But it’s not always essential — and in some cases, not even recommended.
Let’s break it down…
✅ What Is Sealing?
Sealing involves applying a protective coating over surfaces like block paving, concrete, or natural stone. The sealant acts as a barrier against water, oil stains, algae, moss, and even UV damage. It can also enhance the colour of your surface, giving it a “wet look” or a clean, matte finish depending on the type used.
🛡️ What Are the Benefits of Sealing?
1. Blocks Water Penetration
Sealing helps prevent water from soaking into the surface, which can reduce freeze-thaw damage in winter and stop erosion over time.
2. Reduces Weed Growth & Moss Regrowth
By sealing the gaps between blocks or stones, it becomes harder for weeds, algae, and moss to take hold. It doesn’t eliminate the problem forever — but it certainly slows it down.
3. Makes Cleaning Easier
Dirt and stains can’t cling as easily to a sealed surface, meaning pressure washing becomes quicker and more effective.
4. Enhances Appearance
Sealers can revive faded surfaces, deepen natural colours, and create a more uniform finish — especially on older block paving.
5. Extends Lifespan
With regular maintenance and sealing, your surfaces are protected from everyday wear and tear, saving you money in the long run.
❌ Is Sealing Ever a Waste of Money?
Yes — if done at the wrong time, with the wrong product, or on the wrong surface.
You should avoid sealing if:
The surface is newly laid and hasn't fully cured (especially concrete or block paving)
There is still moisture trapped underneath (this can seal in problems)
A poor-quality sealer is used
It’s applied by someone inexperienced — DIY sealing is one of the most common mistakes we see
In these cases, sealing can actually do more harm than good, trapping moisture or causing patchy results.
🧪 Are All Sealers the Same?
Not at all. There are different types of sealers for different materials and finishes:
Acrylic-based sealers – common for block paving, offer colour enhancement and stain resistance
Polyurethane sealers – tougher, longer-lasting, often used for high-traffic areas
Silane/siloxane sealers – more breathable, better for natural stone
Choosing the right sealer is crucial — and it depends on your surface, how it’s used, and what finish you want.
🕒 How Often Should You Reseal?
We recommend resealing every 2–4 years, depending on traffic and weather conditions. If you notice fading, increased weed growth, or water soaking in more quickly — it might be time.
✅ Final Verdict: Worth It — When Done Properly
Sealing isn’t a gimmick — but it does need to be done professionally and for the right reasons. Think of it like waxing your car or applying sunblock: not always essential, but smart protection if you want things to last.
