Properties that have been extended or altered upward carry a particular complication, and it shows clearly once the growth is removed. A loft conversion with new dormers, a storey added above an existing house, a rear extension rendered to match, a garage converted and re-rendered: each brings new material alongside old, and the two never behave identically. Age of the coating is the first difference between them. New render is dense and low in porosity, so it takes less solution, dries quickly and colonises slowly. Render thirty years older is absorbent, holds moisture and carries growth deeper in the texture. Treating both at one dilution under-treats the old and over-wets the new. Colour is the second difference, and the more visible one. Even where a new section was specified to match, weathering diverges immediately. The original has faded under ultraviolet exposure and the addition has not, so once both are clean the difference is visible even though the growth had been disguising it. Detailing is the third of them. Additions bring beads, movement joints and abutment details that the original wall does not have, and the junction between old and new is always a line. None of that prevents a good result. What it prevents is a perfectly uniform one, and saying so before the work is the whole point of a survey. Properties in Fen Ditton that have been extended are treated as several areas rather than one building, with each section worked at its own dilution and dwell, and the likely finished appearance described elevation by elevation rather than summarised in a sentence.
Spotting where a building has been altered is a survey skill, and it matters because it determines both the method and what can honestly be promised. The signs of an alteration are fairly consistent. A change of texture, however subtle, between two areas of what appears to be one wall. A vertical line at a junction where old meets new. A slightly different colour visible in raking light even beneath uniform growth. Beads present on one section and not the other. A change in how the surface sounds when tapped. Filled openings where a window or a door once was. Pro Clean Xtreme records each of those, photographs them and points them out at the survey rather than discovering them halfway through an application. Recording all of that does two useful things. It sets the method, since dilution, application rate and dwell all differ between a modern thin-coat addition and thirty-year-old sand and cement on the same elevation. And it sets expectations, because once the growth is gone the boundary between them will be visible. Where an owner does not know what was done, the record becomes useful history for the building, and it is provided whether or not the work goes ahead. The alternative is treating an elevation as one surface, under-treating the absorbent half, over-wetting the modern half and leaving a customer surprised by a two-tone wall. Householders in Fen Ditton with extended or altered properties therefore receive a written survey naming each section, the system found on it and what the finish will realistically look like.
An extension adds rather more to a quotation than its area alone suggests, and it is worth explaining exactly why. The obvious part of it is straightforward enough. A single-storey rear extension adds wall, and that is measured and priced at the ordinary rate of £4 to £8 per square metre. The less obvious part is that an extension also adds a good deal of complexity. A second render system means the elevation is worked as two areas with separate dilution and dwell. New beads, movement joints and abutment details all need individual attention. And the extension itself frequently obstructs the elevation above it, so the original wall can no longer be approached from the ground directly and has to be worked at an angle from a set-back position. Dormers added in a loft conversion do the same at the other end of the building, since each has cheeks, a face and detailing around glazing, and they sit at the height where accuracy is hardest to achieve. The net effect is that extended properties sit toward the top of their bands rather than exceeding them: £280 to £430 terraced, £400 to £620 semi-detached and £550 to £880 detached. Substantial two-storey additions and buildings extended more than once are quoted individually. What does not happen is an extension being treated as a bonus area at the standard rate with the additional time absorbed silently, since that produces either a rushed job or a figure that moves later. Properties in Fen Ditton are quoted with the original building and each addition identified separately in writing.
Remove years of dirt, grime, algae and staining for a cleaner, fresher finish.
Professional techniques designed to protect your surfaces while delivering outstanding results.
Keep your property looking its best with regular render cleaning.
Keep your property looking clean, fresh and well maintained with professional render cleaning in Fen Ditton. Over time, rendered walls can become affected by algae, moss, dirt, staining and other environmental contaminants, leaving the exterior looking tired and discoloured. Our professional render cleaning service is designed to safely restore the appearance of rendered surfaces without causing unnecessary damage.
Boathouses, rowing clubs and riverside sports facilities present render cleaning in one of the dampest settings any building occupies, and it shows plainly on the walls. Permanent proximity to water is the defining condition. Humidity is high year round, elevations facing the water dry slowly, and the shaded side of a boathouse frequently carries the heaviest colonisation of any building of comparable age. Intervals are therefore shorter here than the aspect alone would suggest, and that is stated honestly rather than glossed over. Environmental care governs the method. The fall of the ground is established before anything begins, and application is limited strictly to elevations from which run-off can be reliably contained away from the water. Where it cannot be, an elevation is not treated rather than treated hopefully. Product volumes are kept to the minimum effective quantity by extending dwell rather than raising concentration, and wind limits are tighter than on an ordinary site. Boats and equipment are the practical consideration. Racking, hulls, blades, launching areas, pontoons, staging and landing stages are all relocated where possible and comprehensively sheeted where not. Timing follows the water. Regattas, head races, training schedules and the club calendar all restrict when a site is genuinely quiet, and winter maintenance periods are the usual window. Documentation is issued with every quotation: risk assessments, method statements addressing environmental controls explicitly, COSHH data sheets and public liability certification. Club captains, boatmen and facilities managers responsible for premises in Fen Ditton can arrange a survey, a written specification and a fixed price with a phased programme.
