Professional Patio Grouting That Lasts
If your patio is in poor condition with crumbling, cracked, or missing grout, it’s time to seek professional help. At ADC Pressure Washing, we provide expert grouting services for patios throughout London and the surrounding areas. Whether you’re grouting patio slabs, restoring a weathered surface, or installing grout for outdoor tiles, we ensure your patio looks immaculate, functions effectively, and can withstand the British weather.
Why Proper Grouting Matters for Your Patio
Many homeowners overlook the importance of grout when it comes to patios. But in reality, grout does more than hold the slabs together:
- It prevents water ingress and structural damage
- It deters weed growth and insect infestation
- It helps maintain the alignment of slabs
- It boosts the overall visual appeal of your outdoor space
Without quality grout, your patio won’t just look tired—it could start to shift or break apart.
What to Use for Patio Grout?
Choosing the right grout for your patio is crucial to its long-term performance, especially in the ever-changing UK climate. At ADC Pressure Washing, we understand that not all grouts are created equal. That’s why we only work with high-quality, professional-grade grout materials that are specifically formulated for outdoor use.
As a trusted name in exterior cleaning and maintenance across London and its surrounding areas, ADC is recognised for combining technical expertise with meticulous attention to detail. We take the guesswork out of patio maintenance by guiding homeowners and commercial property managers on the best grout options for their specific environments, usage, and paving materials.
Our Go-To Patio Grout Qualities Include:
- ✅ UV-resistant – Prevents colour fading and surface degradation caused by prolonged sun exposure, keeping your patio looking fresh year-round.
- ✅ Waterproof – Minimises water absorption and protects against frost heaving and cracking during colder months.
- ✅ Flexible – Designed to accommodate slight ground shifts and slab movements, reducing the likelihood of cracking.
- ✅ Mould and algae-resistant – Essential for maintaining a hygienic, clean, and visually appealing patio surface.
Whether you’re dealing with natural stone, porcelain, concrete, or ceramic tiles, our expert technicians will select the ideal grout to ensure it bonds securely, cures properly, and enhances the longevity of your patio.
At ADC, we don’t believe in one-size-fits-all solutions. Our team assesses each project individually to recommend the best patio grouting material tailored to your patio’s design, layout, and drainage conditions.

How Long Should Patio Grout Last?
A question we frequently hear from our customers is:
“How long should patio grout last?”
The durability of patio grout can vary depending on several key factors:
- 🧱 Type of grout used – Not all grouts are suitable for outdoor use. High-performance, polymer-modified, or resin-based grouts offer superior longevity and durability.
- ☔ Weather exposure – Constant freeze-thaw cycles, direct sunlight, and heavy rain can degrade grout faster without proper protection.
- 🚶♂️ Usage frequency – Patios in high-traffic areas (e.g., walkways, commercial outdoor seating areas) may wear out more quickly.
- 🧽 Maintenance & sealing – Regular cleaning, sealing, and prompt repairs significantly extend the lifespan of grout.
Average Lifespan
Professionally applied, high-quality patio grout—such as the kind used by ADC—typically lasts between 5 and 10 years and, in some cases, even longer.
Professional company
Why Choose ADC for Long-Lasting Results?
As a company committed to long-term customer satisfaction, ADC Pressure Washing doesn’t just “fill the gaps”—we ensure your patio grout performs and lasts. We use:
- Industry-approved outdoor grout systems
- Professional-grade application tools
- Pre-cleaning and joint preparation for optimal adhesion
- Expert sealing recommendations post-grouting
Our experience in grouting patio slabs, outdoor tiles, and complex paving layouts allows us to deliver finishes that not only look stunning but also stand the test of time.
Grouting Patio Slabs:
Ideal for All Types of Paving
We work with all types of patio materials:
- Natural stone (sandstone, limestone, slate)
- Concrete slabs
- Porcelain and ceramic tiles
- Granite and marble pavers
Whether you’re grouting patio slabs for the first time or replacing failing grout, we tailor our approach to suit the surface and setting.
Is Grout Permeable?
When discussing outdoor grouting, many customers often ask whether grout is permeable. The answer is that it depends. Traditional cement-based grout can absorb water over time, potentially leading to issues such as moss growth or frost damage. For this reason, we typically use non-permeable, resin-based or polymer-modified grouts for most patio applications.
Benefits of non-permeable grout:
- No water ingress
- No frost cracking
- Prevents efflorescence and algae growth
We select the right grout type based on your patio’s exposure, traffic, and drainage needs.

Grouting Outdoor Tile Patios for Durability and Beauty
Grouting outdoor tile patios requires precision. Gaps that are too wide or poorly sealed can result in serious long-term issues. Our experienced technicians ensure that the joints are tightly sealed, evenly spaced, and visually appealing.
Whether you have:
- Modern ceramic tile patios
- Decorative mosaic outdoor floors
- Or slip-resistant textured tiling
—we’ll ensure the finish is not only stunning but also built to last.

FAQ
We Are Here To Help You With Any Questions You May Have
What is grouting a patio?
Grouting a patio involves filling the gaps or joints between paving slabs or tiles with a suitable material—usually cement-based or resin-based grout—to secure the slabs in place, prevent weed growth, and protect against water damage.
Why is grouting patio slabs important?
Grouting patio slabs is crucial for maintaining structural stability, enhancing aesthetic appeal, and ensuring long-term durability. It helps lock the slabs in place, reduces shifting, prevents weed and moss growth, and protects against water ingress and frost damage.
What should I use for patio grout?
For optimal results, use a flexible, waterproof, and UV-resistant grout designed explicitly for outdoor use. Resin-based and polymer-modified grouts are ideal because they’re durable, easy to apply, and resistant to weather conditions. Learn more.
How long should patio grout last?
High-quality patio grout can last between 5 and 10 years or more, depending on the type of grout, weather exposure, foot traffic, and the level of maintenance and sealing.
Can I grout a patio myself, or should I hire a professional?
While DIY grouting is possible, hiring a professional like ADC Pressure Washing ensures proper surface preparation, accurate application, and long-lasting results. Professionals also use premium products and tools that may not be available in DIY stores.
What's the difference between indoor and outdoor grout?
Indoor grout is typically less durable and weather-resistant than outdoor grout. Outdoor grout must withstand UV rays, moisture, and temperature fluctuations, making it more robust and often more flexible.
How do I know if my patio grout needs to be replaced?
Signs your grout needs replacing include cracking, crumbling, discolouration, weed growth, or loose patio slabs. If your patio grout is failing, it’s essential to address the issue promptly to avoid further damage.
Is grout permeable?
Traditional cement-based grout can be permeable, allowing water to pass through. However, modern outdoor grouts used by professionals, such as ADC, are often non-permeable, helping to protect your patio from moisture and frost damage.
What is the best type of grout for outdoor tiles?
The best grout for outdoor tiles is typically a resin-based or polymer-modified grout. These types are water-resistant, UV-stable, and flexible, making them ideal for patios, balconies, and other exposed surfaces.
How long does it take to grout a patio?
The time it takes depends on the size and layout of the patio, the joint width, and whether old grout needs to be removed first. On average, grouting a medium-sized patio takes 1 to 2 days, including drying time.
Can you grout over old patio grout?
It’s not recommended to grout over old, damaged patio grout. The existing grout should be removed, and the joints should be cleaned thoroughly to ensure proper adhesion and a lasting finish.
How can I maintain my patio grout?
To maintain patio grout, regularly clean your patio with mild detergent, avoid harsh chemicals, remove weeds or moss promptly, and consider applying a grout sealer to increase durability and prevent water ingress.
Does the weather affect grouting a patio?
Yes, weather plays a significant role. Avoid grouting in rain or extreme cold, as this can affect the curing process. Dry, mild conditions are ideal. ADC Pressure Washing monitors weather forecasts to ensure optimal results during installation.
Can I use the same grout for all types of patio slabs?
Not always. Different materials (e.g., sandstone vs. porcelain) may require different types of grout. Our team at ADC Pressure Washing selects the most suitable grout based on the slab type, joint size, and anticipated exposure.
How much does patio grouting cost in London?
The cost of grouting a patio in London varies based on the patio size, grout type, and labour involved. On average, prices start from £10 to £20 per square metre, but a custom quote from ADC Pressure Washing will provide an accurate cost breakdown.
