Re-Rendering Your Walls? A Proper Survey Means No Nasty Surprises in Shirley

Re-rendering is often the right answer when existing render is failing across an elevation — but the new coat only lasts if the old one is removed properly and the reason it failed is fixed. This is a quoted project, not a quick hourly patch, because the scope depends on what lies behind the existing render. Here is how we survey, specify and stage the work.

When re-rendering makes sense

If render is blown across large areas, hollow-sounding under tapping, cracked in a network, or patched so many times the wall looks like a collage, repeated spot repairs are usually false economy. A full re-render gives the wall a uniform finish and resets its weather protection. It is also the moment to change the system — for instance, replacing a hard cement render that has trapped moisture on an old solid wall with a breathable lime-based system, or switching from textured to smooth finish.

The survey: understanding why it failed

Before quoting, we survey every elevation. We sound the existing render to find hollow and solid areas, check the exposed substrate where appropriate, and look for damp, salts, cracking and structural movement behind it. We inspect the details — sills, gutters, downpipes, flashings, vents and service entries — because water from any of those can destroy a fresh render within a season. We check ground levels against the damp course and note any vegetation or access issues around the house.

If the survey reveals structural cracks or bulging walls, those need a structural engineer's assessment before we render. We make the area safe and refer you rather than cover a movement problem with a new finish. Where damp or a leak is the culprit, that is remedied before the new render specification is finalised.

How the project proceeds

The existing render is removed back to a sound substrate, with dust and debris controlled and disposed of by prior agreement. The wall is prepared: cleaning, raking out joints, drying saturated areas, applying bonding coats or mesh where specified, and fixing beads and stops at openings and corners. New render is applied in the specified layers and finish, with proper curing time between each coat — that time is built into the schedule, not left to guess.

We agree a defined working day on the scope and explain how the work is staged. The estimate for the initial visit covers 480 minutes — eight working hours on site — within the agreed scope. Multi-day projects are staged elevation by elevation, with a clear record of which walls are complete after each day. If stripping the old render reveals something different from what the survey showed, we pause, tell you what we found and re-quote before proceeding. No surprise additions.

Weather, disruption and timing

Render needs dry conditions and frost-free curing, so dates are provisional around suitable weather — we tell you clearly if a forecast forces a delay rather than work into conditions that ruin the finish. Windows and doors are masked and protected, and scaffolding or tower access is used where the building needs it. The work is messy; we protect plants, paths and nearby surfaces, and agree waste handling with you before starting.

Aftercare and honest limits

A new render has no maintenance-free lifetime and we cannot guarantee against future cracking, settlement or weather damage. It may weather differently over time from adjacent areas, and early cracks should be reported and sealed before winter. Keep gutters clear, avoid pressure washing and inspect the finish each spring.

Booking your survey

Book through maintenance-men.com or by phone. You pay a booking fee when you book, and labour is charged hourly at a rate that depends on how soon you need the visit. The full project cost is quoted and approved before work starts, with parts and materials quoted separately. Send photographs of the worst areas and tell us the house type, approximate size and finish you want so we can plan the survey.
