Brick & Stone Cleaning
Specialist cleaning for all types of brickwork and stonework. We safely remove pollution staining, organic growth, efflorescence, and discolouration from facing brick, engineering brick, natural stone, and decorative masonry. Our controlled pressure settings preserve pointing and mortar whilst delivering dramatic transformation.
Render & Pebbledash Cleaning
Expert cleaning for rendered and pebbledash walls. We remove algae, moss, and atmospheric staining that makes render appear dirty and discoloured. Our careful techniques clean effectively without damaging render surfaces or causing water ingress. Often combined with our exterior building cleaning for complete property refresh.
Our brickwork and render cleaning service covers all aspects of exterior wall restoration for domestic and commercial properties across Darlington & County Durham. We specialise in removing the atmospheric pollution staining that gradually darkens brickwork over time, particularly noticeable on north-facing walls and properties near main roads. This pollution combines with organic growth to create the characteristic dark, dirty appearance that makes properties look older and poorly maintained. Our thorough cleaning process uses variable pressure settings and appropriate cleaning solutions to lift this contamination without damaging the underlying masonry or pointing. For rendered walls, we tackle the green algae growth that commonly affects external wall insulation systems and traditional sand-cement renders, using techniques specifically designed for these surfaces that avoid forcing water through the render into the wall cavity. We also address efflorescence (white salt deposits) that can appear on brickwork and concrete, treating the cause rather than just removing the visible deposits. Many of our brickwork cleaning clients also benefit from our pathway cleaning services to refresh garden walls and boundary features. Every cleaning job includes careful assessment of pointing condition, mortar type identification, and appropriate cleaning method selection. Our friendly team takes pride in providing a courteous, professional service from initial quote through to completion. Special discounts available for over 65’s on all domestic cleaning services.

Our Professional Brickwork & Render Cleaning Process
When you choose Xtreme for your brickwork and render cleaning needs, you’re getting a comprehensive, quality-focused service from start to finish. We begin every job with a thorough inspection of your walls, identifying the masonry type, mortar composition, pointing condition, and level of soiling. This allows us to select the appropriate pressure settings, cleaning methods, and solutions for your specific property. We check for any existing damage, loose bricks, deteriorating pointing, or cracks that should be addressed before or after cleaning. Before we start any cleaning work, we carefully protect surrounding areas including windows, doors, plants, and garden features.
For brickwork cleaning, we assess whether your property has lime mortar (common in pre-1920s buildings) or cement mortar (standard in modern construction). Lime mortar is softer and requires lower pressure settings and gentler techniques, whilst cement mortar can typically withstand higher pressures. We identify the brick type – soft facing bricks require very careful cleaning, whilst engineering bricks (the dense, dark bricks often used for damp courses and industrial buildings) can handle more robust cleaning. Historic properties with handmade or reclaimed bricks receive particularly careful attention.
We begin cleaning by applying appropriate pre-treatment solutions where necessary. For atmospheric pollution staining, we use professional masonry cleaners that break down the bonded contaminants. For organic growth including algae, moss, and lichen, we apply biocide treatments that kill the growth and allow easier removal. These solutions need dwell time to work effectively, so we apply them systematically and allow proper contact time before pressure washing.
The pressure washing itself is carried out using carefully controlled settings and techniques. We work systematically across the wall surface, typically from bottom to top to prevent streaking, maintaining consistent distance and movement speed for even results. We pay particular attention to mortar joints, cleaning them thoroughly without eroding the mortar itself. For properties with deteriorating pointing, we use even gentler techniques and will recommend repointing services before cleaning if necessary.
For rendered walls, we use different techniques depending on the render type. Modern thin-coat renders and external wall insulation (EWI) systems require particularly careful cleaning using low-pressure methods and soft washing techniques to avoid forcing water through the render into the insulation behind. Traditional sand-cement renders can typically handle higher pressures but still require expertise to avoid surface damage or water penetration. Pebbledash (dry-dash finish) requires specific approaches to clean between the aggregate stones without dislodging them. Tyrolean and other textured renders are cleaned using methods appropriate to their particular finish.
Throughout the cleaning process, we carefully manage water runoff to prevent flooding, protect planted areas, and avoid affecting neighbouring properties. We control pressure and direction to avoid damaging window seals, door frames, or driving water into wall cavities through any compromised areas. Once the main cleaning is complete, we conduct a detailed inspection to ensure we’ve achieved the best possible results, targeting any remaining stubborn stains or areas needing additional attention.
Finally, we thoroughly remove all debris and ensure your property is left spotless. For properties with rendering that’s prone to organic growth, we can apply protective biocide treatments that inhibit regrowth and extend the time between professional cleans. Before we leave, we walk you through the completed work and provide maintenance advice. Many customers complement their brickwork cleaning with our roof cleaning services for a complete property transformation.
Types of Brickwork & Render We Clean
Our experienced cleaning team works with all types of masonry materials commonly found on Darlington & County Durham properties. Facing brickwork including traditional clay bricks, wire-cut bricks, and textured facing bricks responds well to professional cleaning. We restore the original colour and appearance by removing pollution staining and organic growth. Engineering bricks – the dense, dark bricks used for foundations, damp courses, and Victorian industrial buildings – can be cleaned effectively using appropriate higher-pressure settings.
Handmade and reclaimed bricks found on period properties require particularly gentle cleaning techniques to preserve their character and soft surfaces. London stock bricks, Accrington bricks, and other regional brick types each have specific characteristics that we understand and respect during cleaning. Calcium silicate bricks (also called sand-lime or Fletton bricks) common in inter-war and post-war construction clean beautifully but require care to avoid surface erosion.
Natural stone walls including sandstone (common in Darlington & County Durham due to local quarries), limestone, granite, and **slate all benefit from professional cleaning but require very different approaches. Sandstone is relatively soft and porous, requiring gentle cleaning and careful pressure control. Limestone is even softer and can be damaged by inappropriate cleaning methods or acidic cleaners. Granite and other hard stones can tolerate more robust cleaning. We’re experienced with all stone types and use appropriate methods for each.
Modern renders including thin-coat renders, acrylic renders, silicone renders, and monocouche renders used on contemporary properties require specialist cleaning approaches. These systems are designed to be breathable and must be cleaned using methods that don’t force water into the substrate behind. Traditional sand-cement renders on older properties can typically handle higher-pressure cleaning but still need expert assessment of condition before work begins.
Pebbledash and roughcast finishes that were popular from the 1920s-1970s accumulate dirt and organic growth in their textured surfaces. We clean these effectively using techniques that remove contamination without dislodging the aggregate coating. Tyrolean, spar dash, and other textured renders each require specific cleaning approaches that we’re experienced with.
External wall insulation (EWI) systems now common on social housing and retrofitted properties require very careful cleaning using only low-pressure soft washing methods. These systems can be damaged by pressure washing, and improper cleaning can void system warranties. We follow manufacturer guidelines for all EWI cleaning. Painted render and painted brickwork can be cleaned using appropriate methods that remove dirt without damaging sound paint, though failing paint may be dislodged during cleaning.
We also clean decorative masonry including corbelling, string courses, and architectural features, garden walls and boundary walls, retaining walls, brick or stone steps, chimney stacks (see our chimney repair services), and commercial building facades for offices, retail units, and industrial premises – often as part of our commercial building cleaning services.
Our team understands that different masonry materials have different characteristics, porosity levels, and cleaning requirements. We have the knowledge, equipment, and experience to deliver outstanding results safely across all wall types. If you’re planning building work, we can coordinate with roofing projects or advise on cleaning requirements after construction. If you’re unsure about the best approach for your specific brickwork or render, simply contact us – we’re always happy to advise.
Frequently Asked Questions About Brickwork & Render Cleaning
How much does brickwork and render cleaning cost in Durham?
Brickwork and render cleaning costs vary depending on the wall area, height, material type, and level of soiling. A typical terraced house front elevation usually costs £150-£300, whilst a detached house with all walls cleaned may be £400-£800. Taller properties requiring scaffolding or cherry picker access are priced accordingly. Commercial buildings are quoted individually based on size and access requirements. We provide free, no-obligation quotes for all jobs, so you’ll know the exact cost before any work begins. We pride ourselves on transparent, competitive pricing with no hidden charges. Special discounts are available for over 65’s, and we often offer better rates for multiple services booked together, such as brickwork cleaning combined with driveway cleaning or roof cleaning. The cost of professional cleaning is minimal compared to repointing or rendering repairs that become necessary when walls are neglected.
Will pressure washing damage my brickwork or pointing?
When carried out correctly by experienced professionals using appropriate equipment and techniques, pressure washing is completely safe for brickwork and will not damage sound pointing. Our technicians use carefully controlled pressure settings based on your specific masonry type and mortar composition. We maintain proper distance from the surface and use appropriate nozzles and techniques. However, this expertise is crucial: incorrect pressure washing is a common cause of masonry damage including eroded pointing, damaged brick surfaces, and forced water penetration. DIY pressure washing with hire equipment frequently causes problems through excessive pressure or incorrect technique. If your pointing is already deteriorating, we’ll identify this during inspection and recommend repointing work before cleaning if necessary. Sound, well-maintained pointing will not be damaged by our professional cleaning methods. With over 10 years’ experience and full insurance coverage, your property is in safe hands with Xtreme.
How often should I have my brickwork cleaned?
For most Darlington & County Durham properties, professional brickwork cleaning every 3-5 years maintains appearance and prevents long-term staining. Properties on main roads, in industrial areas, or with significant atmospheric pollution exposure may benefit from more frequent cleaning every 2-3 years. North-facing walls and areas with poor drainage that develop organic growth more readily might also need more frequent attention. Rendered walls, particularly those prone to algae growth, often benefit from cleaning every 2-3 years. Regular cleaning is actually beneficial for masonry longevity by preventing organic growth from retaining moisture against the surface and by removing acidic pollution deposits before they can damage mortar or brick surfaces. The modest cost of periodic cleaning is far less than major repointing or render replacement caused by neglect. Properties with modern EWI systems should follow manufacturer recommendations, typically cleaning every 2-3 years to maintain performance and appearance.
Can you remove efflorescence from brickwork?
Yes, we can remove the visible white salt deposits (efflorescence) from brickwork, though it’s important to understand that efflorescence is a symptom of moisture movement through the masonry rather than just surface dirt. Our cleaning removes the surface deposits, dramatically improving appearance. However, if the underlying moisture issue isn’t resolved, efflorescence may return over time. During inspection, we’ll assess whether efflorescence indicates a potential damp problem that needs addressing. For new buildings, efflorescence is common during the first year or two as the building dries out and is usually not a concern – cleaning removes it effectively. For older properties showing new efflorescence, we’ll recommend investigating the moisture source, which might be rising damp, penetrating damp, or condensation issues. We can clean the visible efflorescence whilst advising on any underlying issues that might need attention to prevent recurrence.
Will cleaning render cause damp problems?
Professional cleaning using appropriate methods will not cause damp problems when carried out correctly. Our technicians understand render systems and use techniques specifically designed to avoid forcing water through the render into the wall cavity or insulation behind. For modern thin-coat renders and EWI systems, we use low-pressure soft washing methods that clean the surface without driving water into the substrate. For traditional renders, we control pressure and avoid directing water into cracks, gaps around windows, or other vulnerable areas. However, if your render already has cracks, blown areas, or other damage, pressure washing could potentially allow water penetration through these existing defects – we’ll identify such issues during inspection and advise whether repairs should be completed before cleaning. Sound, well-maintained render will not develop damp problems from professional cleaning. In fact, regular cleaning helps prevent damp by removing organic growth that can retain moisture against the render surface and cause deterioration over time.
Can you clean painted brick or render?
Yes, we can clean painted brickwork and render, though the approach depends on the paint’s condition. For walls with sound, well-adhered paint, we use carefully controlled pressure and appropriate techniques to remove dirt and organic growth without stripping the paint. This refreshes the appearance whilst preserving the protective coating. However, if existing paint is flaking, peeling, or poorly adhered, cleaning will likely remove loose paint – this isn’t damage but rather removal of coating that was already failing and would soon peel naturally. In these cases, we’ll advise that complete paint removal and repainting will give better long-term results than trying to clean around failing paintwork. For unpainted masonry that you’re considering painting, we strongly recommend professional cleaning first to provide the best surface for paint adhesion. We’ll assess your specific painted surfaces during inspection and advise honestly on the best approach for your property.
