A Comprehensive Guide To Block Paving Driveway Cleaning & Weeding
Living in Glasgow means we’re no strangers to rain. While our lush, green landscapes thrive in the damp climate, unfortunately, so do the weeds and moss on our driveways. If your once-pristine block paving is starting to look a bit green around the edges, don’t worry, you’re not alone.
Regular driveway maintenance is essential, not just for keeping up your home’s kerb appeal, but for preserving the lifespan of the paving itself. Moss and weeds can destabilise the sand joints over time, leading to loose pavers and potential damage.
With a bit of elbow grease and the right know-how, you can restore your driveway to its former glory. As a leading driveway installer, The Glasgow Paving Company knows what it takes to keep your block paving driveways looking pristine and is here to help homeowners across the region.
This guide walks you through the simple steps to block paving driveway cleaning, including how to weed and protect your block paving in Glasgow’s unique weather conditions.
Tools and Materials Needed For Block Paving Driveway Cleaning
Before you get started, you need to gather your supplies for block paving driveway cleaning. Having everything to hand will make the job much smoother.
We’d recommend the following:
- Broom or stiff brush: Essential for sweeping away debris and scrubbing.
- Dry brush: Use a dry brush to remove loose debris, moss, and dirt, and to prepare the surface before applying cleaning solutions.
- Pressure washer: Great for deep cleaning, but optional if you prefer a hose and scrub method.
- Block paving cleaner: A specialised product designed to remove dirt, moss, mould, and algae from block paving. Always follow the manufacturer’s instructions for best results.
- Bucket: Needed for mixing cleaning solutions such as bleach and water.
- Weed killer: Useful for stubborn roots (ensure it’s safe for residential use).
- Jointing/kiln-dried sand: Vital for refilling the gaps between pavers.
- Sealer (optional): For added protection against the elements.
- Safety gear: Gloves and goggles are a must, especially if using chemicals or a pressure washer.
- Weeding tool or scraper: For manually hooking out moss and weeds.
Step 1: Remove Moss and Weeds
The first step in your block paving driveway cleaning journey is tackling the growth head-on. Moss can take hold surprisingly quickly between pavers.
This is a key feature for maintaining your block paving driveway through winter, as we explore in our post How to Maintain Your Block Paving Driveway Through Glasgow Winters, but persists throughout the year with the ongoing wet conditions of the region.
After applying a weed killer, it’s important to note that using bleach or harsh chemicals can cause discolouration in most block pavers. Consider alternative methods, such as vinegar, to help preserve the appearance of your driveway.
Manual Removal
Start by removing larger weeds by hand. Grasp them close to the base and pull firmly to ensure you get the root.
For tighter gaps or stubborn moss, use a weeding tool or a simple kitchen knife to scrape out the debris from between the blocks. It’s satisfying work and makes a huge difference instantly.
Chemical Treatment
If you’re facing a particularly stubborn invasion, you might consider a weed killer. Apply this a few days before you plan to wash the driveway to allow it to take effect.
Always choose a product designed for block paving to avoid discolouration, and apply it on a dry day. Be sure to follow the manufacturer’s instructions for safe and effective application.
Step 2: Power Wash or Clean the Surface
Block paving driveways are some of the best options for Glasgow properties because of their traditional charm, as we explore in our post Why Block Paving Driveways Are Ideal For Glasgow Homes.
To ensure your driveway continues to be an attractive feature of your home, you need to perform regular cleaning. This not only maintains a clean block paving driveway, but can also enhance the appearance of your paved area.
Once the weeds are gone, it’s time to wash away the dirt and grime.
Using a Pressure Washer
If you’re using a pressure washer, proceed with caution. It’s a powerful tool that can strip away dirt in seconds, but if used on too high a setting, it can also blast away the essential sand that holds your blocks together.
- Angle the spray: Keep the lance at a 30-degree angle to the surface.
- Keep your distance: Don’t hold the nozzle too close to the blocks.
- Go easy on the joints: Avoid spraying directly into the gaps to preserve the sand bed underneath.
High traffic areas may need extra attention or more frequent pressure washing to prevent stubborn stains and wear.
The Manual Method
If you’re worried about damaging the sand or don’t own a pressure washer, a standard garden hose and a stiff broom work wonders.
Wet the driveway thoroughly, apply a specialised driveway cleaner if needed, and scrub vigorously. It’s harder work, but it’s gentler on the paving structure.
Step 3: Re-Sanding the Joints
After cleaning, you might notice the gaps between your pavers look a little empty. This is normal, as some sand is inevitably displaced during washing.
Re-sanding is crucial because it locks the blocks in place and creates friction, preventing them from shifting under the weight of your car.
- Wait for a dry day: This is non-negotiable. The blocks and the gaps must be completely dry, or the sand will clump and won’t fill the joints properly.
- Spread the sand: Pour kiln-dried sand over the driveway.
- Brush it in: Use a soft broom to sweep the sand across the surface, guiding it into the joints. Work in different directions to ensure no gaps are missed.
- Compact (Optional): If you can, gently tap the blocks with a rubber mallet or use a wacker plate (if you have access to one) to settle the sand, then top up if necessary.
After sweeping, make sure to remove or level any excess sand from the surface to prevent drainage problems or an uneven finish. Properly sanded joints also act as a barrier, making it harder for new weeds to take root.

Step 4: Optional Sealing for Extra Protection
If you want to protect your hard work and extend the time between deep cleans, consider applying a block paving sealer. For best results, apply sealer to completely dry, clean paving and choose a dry day to ensure proper adhesion and finish.
Why Seal?
A good quality sealer acts as a shield against oil stains, dirt, and water penetration. In our damp climate, it also inhibits the return of moss and algae.
It can also enhance the colour of the stones, giving your driveway the wet look finish that boosts kerb appeal.
How to Apply
- Ensure the driveway is spotless and bone dry.
- Apply the sealer evenly using a roller or sprayer, following the manufacturer’s instructions.
You’ll typically need to reapply this every 2–3 years, depending on how much wear and tear your driveway endures.
Maintenance Tips For Block Paving Driveway Cleaning
To keep your driveway looking fresh year-round, a little regular maintenance goes a long way. Some of the best tips for regular block paving driveway cleaning include:
- Sweep regularly: A quick sweep once a week prevents dirt and seeds from settling in the joints.
- Spot clean: Deal with oil spills, remove oil stains, and tackle tyre stains immediately before they penetrate the stone. Use appropriate cleaners or household remedies like baking soda or vinegar for oil, and hot water with detergent for tyre marks to maintain the appearance of your driveway.
- Check drainage: Ensure water isn’t pooling on the surface, as this accelerates moss growth.
- Watch the weather: After a heavy Glasgow storm, check that sand hasn’t been washed out of the joints and top up if needed.

FAQs
How often should I clean and resand my block paving driveway in Glasgow?
Due to Glasgow’s damp climate, moss and weeds can grow quickly between pavers. It’s best to inspect your driveway every few months, remove weeds as they appear, and re-sand joints at least once a year to keep the surface stable and weed-free.
Can I safely use a pressure washer on block paving?
Yes, but with caution. Use a low-pressure setting and keep the nozzle moving to avoid dislodging sand or damaging the pavers. For delicate areas, brushing with a stiff broom and water is a safer alternative.
Is sealing my block paving driveway necessary?
Sealing is optional but highly recommended. A sealer protects against stains, locks in jointing sand, and helps prevent weed regrowth, extending the lifespan and appearance of your driveway, which is especially important in Glasgow’s wet weather.
