Re-Rendering Costs: What It Costs to Replace Old Render

How much does it cost to re-render a house?

Re-rendering is priced mainly by the area of wall being stripped and replaced. The table compares the indicative rate for a full strip-and-re-render with the rates for rendering a sound wall that doesn’t need stripping.

indicative Ballpark rates to help you budget, not fixed prices. Expect the upper end where the old render is thick and well bonded, where access is awkward, or where substantial repairs are found underneath.

To turn a rate into a budget, estimate the area. As purely illustrative arithmetic, walls totalling 80m² after deducting windows and doors would come to roughly indicative £8,000–£13,600 at £100–£170 per m². Check what each quote’s rate includes: some firms quote all-in, others list scaffolding, sills or repairs separately.

For first-time rendering of sound walls, the whole-house figures in our house rendering cost guide are the better reference. The difference between the two is almost entirely the removal stage and what it uncovers.

Why re-rendering costs more than rendering a sound wall

The new render itself costs much the same whether it goes on bare brick or a freshly stripped wall. What changes is everything that happens before it.

Removal labour. Hacking off is slow, physical work, and it’s paid by the day. Waste. Old render is heavy, and a whole house can fill more than one skip. Repairs. Bare masonry almost always needs some attention — rebedding loose bricks, raking and repointing failed joints, or building out uneven areas — before new render will bond and sit flat. Time on scaffolding. A longer job means a longer hire period.

None of these is optional. A contractor who prices a re-render at sound-wall rates has either missed the removal stage or plans to leave some of the old surface in place.

Signs your render needs replacing, not patching

Render rarely fails all at once. It usually shows warning signs first, and recognising them helps you judge whether you’re looking at a repair or a replacement.

Hollow or “blown” render. Tap the wall gently with a knuckle or the handle of a screwdriver. Sound render gives a solid, crisp note; render that has lost its bond sounds hollow or drummy. A few isolated hollow patches can be cut out and repaired, but widespread hollowness means the render is failing as a system.

Cracking that keeps spreading. Fine hairline cracks are common and often cosmetic. Wide cracks, cracks that reappear after filling, or a web of cracking across an elevation suggest the render is no longer moving with the wall. Our guide to render cracking explains how to read the different types.

Bulging or sections falling away. Render that has bowed outwards or is coming off in pieces has lost its key. Patching won’t hold.

Damp patches inside. Water getting behind cracked render can show up on internal plaster — though rule out gutters, downpipes and ground levels first.

Paint that won’t stay on. Paint that blisters and peels soon after redecorating often points to moisture trapped in or behind the render.

What a re-render actually involves

Knowing the stages helps you read a quote and see where the money goes.

1. Scaffolding and protection. Scaffolding goes up to every elevation, and windows, doors, paths and planting are protected from debris and dust.

2. Hacking off. The old render is removed back to the masonry by hand or with power tools — noisy, dusty work and usually the slowest stage.

3. Disposal. Waste is bagged and skipped as the work goes.

4. Assessing and repairing the wall. With the masonry exposed, the contractor can see cracked or spalled bricks, failed lintels, eroded joints or old repairs, and put them right.

5. Preparation. The wall is cleaned, stabilised and, where needed, levelled or “dubbed out” so the new render goes on at an even thickness. Beads are fixed at corners, edges, reveals and the base.

6. The new render system. A base coat with reinforcing mesh bedded in, primer where the system calls for it, then the finish coat. Each coat needs its curing time.

7. Making good. Fittings are refixed, sills and trims finished, scaffolding comes down and the site is cleared.

The removal stage: where re-render budgets are won and lost

The removal stage is the main reason re-rendering costs more, and it’s also the stage most likely to vary between quotes. How long it takes depends on the wall area, how thick the old render is and how well it’s still bonded.

Skips are part of the cost. If the skip has to sit on the road — common on terraces with no front garden — it needs a permit from the council, which the skip hire firm usually arranges. Whoever takes the waste away should be a registered waste carrier, and as the householder you have a duty to check.

RenderSmart’s specialists remove pebbledash only as part of a full re-render, not as a stand-alone job; our pebbledash removal page explains the process.

How the surface you’re removing changes the price

Not all old render comes off the same way, and the type you have is a good clue to where your price will land within the range.

Blown render that’s already coming away is the quickest to remove, because much of it has lost its bond. The flip side is that the masonry behind it has often been wet, so expect more repairs.

Hard cement render that’s still well bonded in places is slow to break out and can take the brick face with it, which adds making-good before the new base coat.

Painted render with many layers of masonry paint usually comes off with the render, but if it’s been used to hide cracks for years, the wall behind can hold surprises.

Old lime render on a period house needs a different approach. It may be worth repairing rather than replacing, and if it does come off, it should normally be replaced with a breathable system rather than cement. On a listed building, removing historic render usually needs consent first.

What’s underneath: the cost you can’t see yet

Nobody knows exactly what’s under old render until it’s off. A wall can look uniform from outside and hide a patchwork of earlier repairs, mixed brick, filled openings or decaying lintels.

Most of the time, what’s found is minor: loose bricks to rebed, joints to make good, a few areas to build out. Occasionally it’s more significant — a cracked lintel over a window, brickwork damaged by long-term water ingress, or movement that needs investigating before rendering can continue.

That’s why a good re-render quote prices the job as seen and also explains how unforeseen work will be handled — a day rate, a schedule of rates for common repairs, or an agreement to stop and discuss before anything significant is done. Be wary of a quote that’s silent on this, and equally of one that leaves everything open-ended.

Building a contingency into a re-render budget

Because the wall is an unknown until it’s bare, it’s sensible to keep some money back rather than committing your whole budget to the quoted figure.

A few habits keep that contingency under control. Agree in writing how variations are approved — nothing extra goes ahead without your sign-off. Ask the contractor to photograph anything they find and explain it before quoting the fix, so you can see the problem for yourself. Ask for repairs to be priced against a schedule of rates agreed up front where possible, rather than a figure invented on the day. And keep a simple record of each agreed change and its cost.

Discoveries are a normal part of re-rendering, not a sign that something has gone wrong. What matters is that they’re handled openly and that the money only gets spent on work you’ve seen and agreed.

Patch the failed areas, or replace the lot?

Not every tired render needs replacing. If the failure is limited and the rest is sound, a targeted repair can be far cheaper and perfectly effective. As indicative guides:

indicative Repairs on a through-coloured render can be hard to colour-match exactly, so patches may be visible.

The balance tips towards a full re-render when hollow areas are widespread, when cracks keep coming back, when water is getting in across a large area, or when you’re tired of maintaining a painted finish anyway. Repeated patching of a failing render can end up costing more over a few years than replacing it once.

Our guide on whether to repair or replace render walks through the decision, and our render repair cost guide covers repair pricing in detail.

Re-rendering one or two elevations

Render often fails worst on the most exposed side of the house — the wall facing the prevailing weather, or a gable with no overhang — while the sheltered walls stay sound. Re-rendering only the failing elevations can be a sensible use of money.

Two things to plan for. First, the new render will look different from weathered render on the walls you keep, even in a similar colour. Stopping at a corner usually looks deliberate; stopping part-way along a wall rarely does. Second, smaller jobs cost more per square metre, because scaffolding and set-up don’t shrink with the area.

If the remaining walls are likely to need doing within a few years, ask for a price for both options. Doing everything at once means one scaffold, one set-up and a matching finish.

What a re-rendering quote should include

A re-render quote has more moving parts than a straightforward render quote, so check it line by line. It should show:

Scaffolding to every elevation, including any bridging over conservatories or extensions. Removal of the old render, stating whether it’s a full hack-off back to masonry or failed areas only. Waste disposal, including skips and any permit. An allowance or rate for repairs found once the wall is exposed. Preparation, including any levelling or dubbing out. Beads and mesh, with mesh coverage stated. The named render system, finish and colour. Making good around fittings, sills and pipes.

Alongside the price, look for a start date and expected duration, a payment schedule tied to progress rather than a large upfront sum, and a written guarantee. If two quotes differ widely, the explanation is almost always in removal, repairs or mesh.

Re-rendering a semi or terrace: neighbours and access

On attached houses, scaffolding at the front or rear of a terrace may need to sit partly in front of a neighbour’s property, and on a semi the side elevation may only be reachable across shared or neighbouring ground. Scaffolding on or over someone else’s land needs their permission, so agree it in advance.

The junction with a neighbour’s wall needs care too. A good renderer will finish neatly at the party line with a stop bead and protect the adjoining property from dust and debris while the old render comes off. Simply rendering your own wall usually isn’t notifiable under the Party Wall etc. Act 1996, but cutting into or fixing to a party wall can be — ask a party wall surveyor if in doubt. If your neighbour’s render is in a similar state, doing both houses together can share scaffolding and give a consistent finish.

Choosing the new render: an opportunity to upgrade

If you’re paying to strip the wall back anyway, it’s the ideal moment to choose the right system for the long term rather than simply replacing like with like.

If your old render is painted sand and cement, replacing it with a through-coloured system such as silicone render, acrylic or monocouche removes the repainting cycle. Silicone is widely chosen for its water repellency and breathability.

On older solid-wall houses, breathability is the most important decision. Many period homes were originally finished in lime, and a later cement render may be trapping moisture. Re-rendering in lime render or another breathable system can be the right technical choice even though it costs more. If you’re weighing the wider options, our guide to exterior rendering compares the systems.

Regulations that can change the scope of a re-render

In England, Part L of the Building Regulations treats stripping render back to the masonry and re-rendering as renovating a thermal element. Where that renovation covers more than 50% of a wall’s surface, or more than 25% of the whole building envelope, the wall should normally be upgraded to around 0.30 W/m²K, so far as is technically, functionally and economically feasible — usually judged against a simple payback of around 15 years. Traditional solid-wall buildings get special consideration because of breathability and damp risk. Building control should be notified for qualifying work, or a competent person scheme used. Wales and Scotland have their own standards. Our guide to building regulations for re-rendering explains more; always confirm with building control.

If insulation is required or wanted, the cost changes. Insulated render systems run at around indicative £90–£150 per m², excluding scaffolding and old-render removal, so ask for that option to be quoted alongside a standard re-render.

Planning is usually simpler for a like-for-like re-render, but changing the type or colour of render can alter the appearance enough to need permission, and listed buildings, conservation areas, flats and Article 4 areas have tighter rules. Check with your local planning authority first.

How long a re-render takes

A re-render takes longer than rendering a sound wall because of the removal and repair stages. A whole house is commonly a job of a few weeks rather than a few days, depending on the size of the property, the crew, how stubborn the old render is and what’s found underneath. Weather matters too: render shouldn’t go on in frost, heavy rain or very high temperatures. Agree in advance which days will be noisiest so neighbours can be warned. Our guide to how long it takes to render a house has more on timings.

When a full re-render might not be right for you

If the problem is localised, a repair is usually the better spend. Replacing a whole elevation because of one blown patch is rarely good value.

If the render is sound but simply looks tired, the issue may be cosmetic. Cleaning a through-coloured render, or redecorating a painted one, can restore its appearance for far less. Some homeowners also compare masonry wall coatings, a different product with its own strengths, if appearance is the main concern.

If there’s an underlying structural or damp problem, that needs diagnosing and fixing first, or the new render will repeat the failure.

If you’re planning other work soon — an extension, new windows or insulation — coordinate the jobs so you only scaffold and render once.

How to keep re-rendering costs down without cutting corners

Do all the failing elevations at once so you pay for scaffolding and set-up once and the colour matches. Get the wall surveyed properly so the quote reflects reality and unforeseen work is the exception. And compare quotes like for like, checking each includes removal, disposal, preparation, mesh and the same named system. What you shouldn’t cut is the preparation — a wall that wasn’t put right first is a common reason new render fails early.

Most of our specialists take on projects from around £3,500, so they’re best suited to larger repairs and re-renders; for a single small job, a local builder or plasterer may be quicker.
