Rendering in London

What this work involves

We provide rendering as a core part of our plastering work. Most people looking for this want Protect and re-finish the outside of a property where render has cracked, blown or stained. What the work involves depends on the condition of the existing surface, so we price from what is there.

Rendering in London

If your property is in London, London, this is work we can quote for. Surrounding parts of London are covered on the same terms.

What is included

This normally includes:

• Full re-render
• Patch repair
• Through-coloured render
• Monocouche
• Bell casts and beads
• Mesh reinforcement

Typical jobs

Typical jobs we are asked about in London:

• Failed render replacement
• New extension finish
• Whole-elevation refresh
• Crack and damp remediation
• Full re-render
• Patch repair
• Through-coloured render
• Monocouche

Preparation and process

Preparation is the part people see least and notice most, so it is not skipped.

1. Assess substrate and detailing
2. Remove failed render
3. Prepare and reinforce
4. Apply coats in sequence
5. Finish and detail edges
6. Clear site

Materials used depend on the substrate and finish: Sand and cement, Silicone thin-coat, Monocouche and Bonding coats and primers.

Suitable properties

Property types this suits around London:

• Terraced house
• Semi-detached house
• Detached house
• Extension
• Bungalow

Problems this solves

Situations where this work is the right answer:

• Hollow or drummy render
• Cracking
• Damp patches inside
• Staining and organic growth
• Paint failure

Local considerations

As a region, London has a mix of building ages, and older walls behave differently to newer plasterboard.

What rendering work covers

• Full re-render — removing failed render back to sound masonry and building the system back up in coats
• Patch repair and making good — cutting out blown or cracked sections and blending into the existing finish
• Through-coloured and silicone systems — finishes coloured throughout rather than painted on, so chips don't show a different colour underneath
• Monocouche — one-coat through-coloured render, typically scraped back to an even texture
• Bell casts, beads and stop ends — the detailing that decides where water leaves the wall instead of tracking behind it
• Preparation and reinforcement — mesh, primers and bonding coats where the substrate needs them

Where a wall needs to breathe — older solid-wall construction in particular — a cement-rich system can trap moisture and cause more harm than the original problem. We'll say so before quoting rather than fitting the wrong product.

Rendering that protects the outside of your home

External render does two jobs at once: it gives the building a clean, uniform finish and it forms the weather layer that keeps driving rain out of the masonry underneath. When render fails, both jobs stop working — hollow patches let water sit against the wall, hairline cracks widen with every freeze, and staining spreads from wherever water is being shed in the wrong place.

We work on solid brick, block, stone and previously rendered walls, using sand and cement systems as well as modern through-coloured and silicone-based finishes. The right specification depends on what the wall is built from and how it needs to breathe, which is why we look at the substrate before recommending a system rather than after.

Problems rendering solves

• Hollow or drummy areas — render that has lost its bond and sounds hollow when tapped; it will eventually come away in sheets
• Cracking — fine crazing is usually cosmetic, while straight or stepped cracks often follow movement or a failed detail underneath
• Damp patches inside — frequently traced to render bridging a damp course or water running behind a cracked bell cast
• Staining and organic growth — green or black marks where water runs down the same path repeatedly
• Patchy paint failure — coatings peeling because moisture is trying to escape through the paint film

Rendering questions

Can you render over existing render?

Sometimes. If the existing render is well bonded across the whole wall, a thin-coat system can go over it after preparation. If large areas sound hollow, overlaying just hides the problem — the new finish will fail wherever the old one lets go, so those sections come off first.

How long does a re-render take?

A typical house elevation is usually a matter of days rather than weeks, but render is weather-dependent. Coats need time between them, and applying in frost or heavy rain damages the finish, so we plan around the forecast rather than pushing on regardless.

Does render stop damp?

A sound render sheds water and keeps the wall behind it dry, which resolves damp caused by water getting into the masonry. It will not fix damp coming from a failed damp course, a leaking gutter or a bridged cavity — those need dealing with first, or the same patches come back.

Will the colour match the rest of the house?

With through-coloured systems we can work to the closest available colour, but a patch repair on a weathered wall rarely disappears entirely, because the old surface has aged. Where an exact match matters, rendering the whole elevation gives a consistent result.

Common questions

Do you cover London?

Yes. London is within our working area for rendering. We confirm timing when you enquire.

Timescales and weather?

This depends on the property, so we would rather answer it properly once we have seen the surface than give a general answer that may not apply to your job.

Do I need to move out or clear the room?

For most jobs the room needs to be clear of furniture and floor coverings protected. We will tell you exactly what to move before we arrive.

How long does the work take?

It depends on the area and how much preparation is needed, and drying time between coats cannot be shortened safely. We give a realistic timescale with the quote instead of a generic figure.

Is there anything you do not cover?

We do not carry out damp-proof course installation, guttering replacement or structural crack repair.

Rendering over existing render?

This depends on the property, so we would rather answer it properly once we have seen the surface than give a general answer that may not apply to your job.

How much does rendering cost?

We do not publish a fixed price, because cost depends on the size of the area, the condition of the existing surface, access and the finish you want. We give a written quote after assessing the job rather than an estimate that changes later.

How we work

We quote in writing, explain what the work involves before starting, and tell you if a different approach would serve the building better. If a job is not right for us, we say so.

What to expect

Every quote starts with understanding the surface and what you want the finish to achieve. We explain the work, the preparation involved and the timescale before any price is agreed, so there are no surprises once the job is under way.

What good work looks like

A rendering job is a sequence of dependent stages, and skipping any of them shows up eventually. The substrate needs to be clean and stable, the base coat needs to bond properly, each coat needs to be flat and consistent, and the finish needs to be applied at the right thickness. Drying time is not optional — it is part of the process, and shortening it is how problems start.

Choosing the right approach

The right approach for a rendering job depends on what is already on the wall or ceiling, what condition it is in, and what the finished surface needs to achieve. Skimming over an existing finish is sometimes the right call; other times it stores up problems. We assess the substrate and recommend the approach that will last, even if it is not the cheapest option.
