What sits on the ground beneath an elevation has a direct effect on the render above it, and the difference between one surface and another is larger than most people would expect. Hard paving is the worst offender by some distance. Rain striking a solid surface bounces back onto the wall with real force, keeping the lowest six hundred millimetres or so wet long after the rest of the elevation has dried, and on a wide paved area that splashback reaches higher still. The band of heavy moss and lichen along the base of so many properties is very largely a paving effect. Gravel is considerably kinder. Loose stone absorbs the impact of falling rain rather than deflecting it, so splashback is minimal and the base of the wall dries at much the same rate as everything above it. Lawn sits between the two. Grass absorbs impact well but holds moisture in the air immediately above it, so a wall rising from turf stays humid at low level even though it takes far less direct splashing. Planted borders are the most difficult of all, combining humidity, shade, restricted air movement and a constant supply of organic debris against the render itself. Levels matter alongside the surface, since ground built up against a wall keeps it permanently damp regardless of what that ground is made of, and a raised bed against render is worse than any paving. Properties in Bourn are surveyed with the ground beneath each elevation recorded, because it explains the condition of the base zone and largely determines how quickly that strip will return after treatment.
Every ground surface beneath a treated elevation needs protecting in some form, and each of them needs protecting in a rather different way. Getting that wrong is the commonest way a good treatment turns into a complaint. Planted borders take the most work by far. They are saturated thoroughly with clean water before anything is applied, so the soil and the plants themselves are already full and cannot take anything up, and anything delicate is sheeted as well as wetted. Pro Clean Xtreme treats that as the single most important part of the preparation, because a damaged border is the complaint customers remember longest. Lawn is wetted rather than sheeted. Grass tolerates dilute solution well provided it is already wet, and covering a lawn for several hours does more harm than the treatment ever would. Paving is wetted before work and washed down thoroughly afterwards, so nothing is left to dry in place and mark the surface. Gravel is the easiest of them, needing little more than a thorough wetting, though anything stored on it is moved out of the way first and put back afterwards. Decking is sheeted rather than wetted, since timber and composite both mark readily and neither of them benefits from anything at all running across the surface. Drainage within the fall of the ground is covered or diverted regardless of the surface, along with gullies, water butts, ponds and any open channel. Householders in Bourn receive a written scope stating what will be protected and how, and everything is reinstated and checked before the crew leaves the property.
Ground protection is entirely invisible in a finished result and a substantial part of the working day, so it is worth explaining exactly how it moves a figure. The straightforward case is a property with paving or gravel laid to every elevation and no planting at all against any of the walls. Protection there is quick, the ground is wetted, work proceeds, and everything is washed down at the end. That property sits at the lower end of its band. The expensive case is a property with mature borders running the length of three elevations, specimen planting close to the render, a lawn to the rear, decking against one wall and a pond within the fall of the ground. Each of those needs a different approach, and saturating a long border properly takes considerably longer than hosing down a path. Add a vegetable garden, fruit trees trained against a wall or anything a customer has spent years establishing, and the time involved doubles again, because none of it is worth risking in order to save twenty minutes. The effect is a property sitting toward the top of its band rather than beyond it: £280 to £430 terraced, £400 to £620 semi-detached and £550 to £880 detached, at £4 to £8 per square metre. None of it is itemised or added afterwards. The ground beneath every elevation is assessed at survey and the protection required is absorbed into the single fixed figure. Properties in Bourn are quoted on what actually surrounds the building as well as on the walls themselves.

Showgrounds, agricultural society venues and permanent event sites present render cleaning across a collection of buildings used intensively for a few weeks and standing quiet for the rest of the year. The building stock is varied and spread across a large site: permanent exhibition halls, livestock and produce buildings, members’ pavilions and offices, catering and retail units, stewards’ accommodation, storage and machinery buildings, and public facilities. The quiet period is the whole of the opportunity, and on these sites it is a generous one. Most of these sites hold one or two major events a year with smaller hires in between, so autumn through early spring offers long uninterrupted windows in which access is unrestricted and nothing has to be worked around. The buildings themselves show the effect of that quiet. Standing unheated and unused for months, frequently with planting growing up against them and rainwater goods unattended, they colonise faster than comparable premises in daily use, so intervals are shorter than the age of the buildings alone would suggest. Where a site hosts events during a programme, elevations are phased around the bookings and nothing at all is treated anywhere near a hire in progress. Livestock buildings bring their own considerations, with water troughs, feed and bedding storage protected or excluded wherever any animals are present. Documentation is issued with every quotation: risk assessments, method statements, COSHH data sheets and public liability certification. Showground and estates managers responsible for venues in Bourn can arrange a whole-site survey, a written schedule with fixed prices per building and a phased programme.
