What a Professional Block Paver Cleaner Does
A professional block paver cleaner is a specialist who restores and maintains block paving surfaces using methods suited to the material and its condition. Unlike DIY pressure washing, professional cleaning involves assessment, targeted treatment, and careful technique to remove moss, algae, black spot, lichen, stains and ingrained dirt without damaging the paving or surrounding areas.
At SavingPaving, we assess each driveway or patio before work begins. This means identifying the type of growth, the paving surface, its condition, and any loose or damaged areas. We then apply biocidal pretreatment where needed, allow suitable dwell time for the treatment to work, and professionally clean the surface using equipment and methods matched to the paving type. A block paver cleaner may also repair loose or sunken slabs, remove failed pointing, apply fresh jointing sand, and recommend sealing or maintenance to protect the restored surface.
The difference between a professional block paver cleaner and someone with a pressure washer is significant. Pressure, chemical choice, dwell times, and technique all affect the result. Done poorly, pressure washing leaves stripes, marks and uneven patches. Professional cleaning reveals the paving's true colour and texture while preserving its integrity.
Block Paving Cleaning: Removing Stains and Growth
Block paving attracts moss, algae, lichen and weeds because these organisms thrive on damp, shaded surfaces. Black spot and lichen colonise suitable paving and are not caused by failed joints. Open joints may collect debris and support weeds and moss growth, but they are not the sole cause of these problems.
Professional cleaning targets the specific growth present. Moss and algae respond to biocidal treatment followed by careful cleaning. Black spot and lichen may require specialist treatment applied before pressure cleaning. Stains from oil, leaf tannin or weathering need assessment to determine the best removal method. A block paver cleaner will choose cleaning pressure, equipment and chemicals to suit the block paving and its condition, ensuring the surface is restored without damage.
After cleaning, the paving must dry suitably before the next stage. This allows the joints to firm up and prepares the surface for re-sanding or sealing if needed. Professional block paver cleaning varies in duration depending on the area size and the level of soiling.
Block Paving Re-Sanding: Restoring Stability and Appearance
Once the block paving is cleaned and dry, re-sanding restores both appearance and function. Kiln-dried jointing sand is brushed into the joints, filling gaps left by weathering or lost sand. This sand is then compacted into the joints, firmed and finished appropriately for the paving type.
Re-sanding serves two purposes. First, it restores the neat appearance of the driveway or patio by filling the joints evenly. Second, it helps stabilise the block paving by providing a compacted base between the blocks. This reduces movement and helps prevent debris and weed seeds settling into gaps.
The process follows professional cleaning. Sand is applied generously across the surface, brushed into the joints with firm, directional strokes, then excess sand is removed. The joints are then compacted using suitable equipment. The result is a neat, finished appearance that restores the block paving's visual appeal.
Why Re-Sanding Matters After Cleaning
Re-sanding after professional block paver cleaning is important because cleaning removes not only dirt and growth but also sand that has been washed away or compacted over time. Without re-sanding, the joints remain open and vulnerable to debris collection and further weed growth. Re-sanding closes these gaps, reduces future maintenance needs, and helps the block paving perform as intended.
A well-sanded joint also supports the effectiveness of any sealing applied afterwards. Sealing works best on prepared, compacted joints rather than loose or open ones. This is why professional block paver cleaning typically includes re-sanding as a key stage before protection is considered.
Sunken Block Paving Repair: Assessment and Solutions
Sunken or rocking block paving is usually caused by movement in the bedding layer beneath the paving, not by failed joints. When blocks settle unevenly, they create trip hazards and an uneven appearance. Jointing alone cannot fix this problem because jointing does not secure inadequately bedded paving or prevent further movement.
Professional assessment is essential. A block paver cleaner will identify which blocks are affected, establish the cause (often poor initial bedding or sub-base settlement), and recommend solutions. Where localised bedding problems are found, blocks may be lifted and relaid on a properly prepared base. This restores stability and a level surface.
Widespread sub-base failure may be more complex. Local repair may be suitable in some cases, whilst other situations may require more extensive work or specialist advice. This is why assessment before committing to repair is crucial. SavingPaving surveys the paving, identifies the problem, and explains honestly whether professional block paving repair can restore it or whether replacement or specialist assessment may be more appropriate.
Block Paving Sealing: Protection and Aftercare
Sealing is an optional stage applied after cleaning, repair and re-sanding where suitable and agreed. A suitable sealer may help protect the block paving by reducing water absorption, minimising staining, and making future cleaning easier. However, sealing is not automatic or suitable for every surface. The choice depends on the paving type, its condition, the site exposure, and the homeowner's needs.
We recommend sealing only where it is genuinely appropriate for the paving and its use. A correctly specified and installed sealer may provide a durable finish, but no sealer is permanent or maintenance-free. Sealing does not prevent all growth or make the surface immune to weathering. It is one part of a maintenance plan, not a complete solution.
After sealing, ongoing maintenance becomes important. SavingPaving offers six-monthly aftercare visits that include sweeping or blowing away debris, reapplying appropriate biocidal treatment, and targeting early regrowth. This routine maintenance keeps the block paving looking cared for and reduces the build-up of moss, algae and weeds. It is far more cost-effective than allowing growth to return to heavy levels before professional cleaning is needed again.
Why Professional Cleaning Beats DIY
DIY pressure washing of block paving often leaves visible stripes, uneven patches and marks where pressure or cleaning solution has been applied unevenly. These marks may fade over time but are often permanent. Professional block paver cleaners avoid this because they understand paving types, appropriate pressures, chemical dwell times, and technique.
A professional block paver cleaner also assesses the paving before starting. This means identifying loose blocks, failed joints, stains that need specialist treatment, and areas where pressure must be reduced. DIY attempts often miss these details, resulting in damage to the paving or surrounding materials like fences, plants and windows.
Equipment matters too. Professional cleaning equipment delivers consistent pressure and flow, combined with chemical application timed correctly. Rental pressure washers and garden hose attachments lack this control. The result is either insufficient cleaning or damage.
Cost is often cited as a reason for DIY attempts, but professional block paver cleaning can be a more effective solution than attempting to repair damage caused by incorrect pressure, chemicals or technique.
How to Choose a Block Paver Cleaner
Finding a reliable block paver cleaner begins with checking credentials and experience. Look for a business that is fully insured, has uniformed staff, and can provide references or examples of completed work. Established businesses with years of experience are more likely to have the knowledge to assess your paving correctly and choose appropriate methods.
A good block paver cleaner will offer a free site survey and detailed quotation before work begins. This allows you to understand what your paving needs and what the work will cost. Be cautious of businesses that quote over the phone without seeing the paving, as they cannot assess its condition properly.
Ask about the cleaning process and what stages are included. A professional approach includes assessment, biocidal pretreatment where needed, professional cleaning, repairs if necessary, re-sanding, and optional sealing and maintenance. Understand what each stage involves and why it matters for your specific paving.
Check whether the business has experience with your paving type. Block paving, Indian sandstone, natural stone, crazy paving and porcelain all require different approaches. A block paver cleaner experienced with all these surfaces is better equipped to protect your investment and achieve the best result.
Finally, look for a business that is transparent about limitations. A reliable block paver cleaner will explain when restoration is suitable and when replacement or specialist assessment may be needed. They will not promise permanent prevention of growth or claim that every problem can be fixed. Honest advice is a sign of professionalism and experience.

Frequently Asked Questions
What does a professional block paver cleaner do?
A professional block paver cleaner surveys your paving, applies biocidal pretreatment where needed, then uses specialist equipment and methods to remove moss, algae, lichen, black spot and ingrained dirt. The process protects the paving material and surrounding plants, unlike DIY pressure washing which can leave stripes and cause damage. After cleaning, the paving may need re-sanding with kiln-dried jointing sand, repairs to loose or sunken slabs, and sealing to protect the restored surface.
Can block paving be cleaned without damaging it?
Yes, when cleaned professionally using methods suited to the paving condition and material. The pressure, equipment, chemicals and technique must all be appropriate. DIY pressure washing often leaves visible stripes and can damage the surface. Professional cleaners assess the paving first, apply suitable treatments, allow proper dwell time, and use controlled methods to avoid harm to the paving, plants, fences and surrounding features.
Should block paving be sealed after cleaning?
Sealing may be suitable depending on your paving type, condition and local environment. A correctly specified and installed sealer can help protect the cleaned surface and reduce regrowth of moss and algae. However, sealing is not automatic and is only applied where appropriate and agreed following professional assessment. Maintenance such as six-monthly biocidal treatment and debris removal also helps keep block paving looking cared for.
How often should block paving be professionally cleaned?
This depends on your location, climate, paving exposure and how much growth develops. Many homeowners benefit from professional cleaning every few years, combined with regular six-monthly maintenance visits. Maintenance involves sweeping or blowing away debris and reapplying biocidal treatment to target early regrowth, helping reduce the build-up of moss, algae and weeds between deeper cleaning cycles.
