The work

Prepare it, then finish it

Render fails for a reason. Water gets in behind it from a gutter, a coping or a bridged damp course, then frost pushes it off the wall. Rendering straight over a blown, hollow area just hides the problem for a season.

So we tap the wall through, take off anything hollow, and sort out what let the water in. Then the wall is re-rendered in sand and cement or a silicone through-coloured system, or repaired and painted in a breathable masonry paint.

  • The wall gets sounded out, so you are not paying to render over a hollow area.
  • Bell drips and beads fitted, which is what stops water tracking back into the wall.
  • Breathable finishes on solid walls rather than sealing moisture in.
  • Being roofers, we fix the gutter that caused it while we are there.

What's included

What rendering & exterior painting covers

  • Survey and hack off

    The wall sounded out and blown or hollow render removed back to sound material.

  • Cause of failure

    Gutters, copings, bell drips and ground levels dealt with so the wall stays dry.

  • Beads and stops

    New corner beads, bell drips and stop beads so edges shed water.

  • Sand and cement render

    Scratch and top coat, ruled off and finished to match the existing wall.

  • Silicone render

    Through-coloured silicone systems over base coat and mesh, no repainting needed.

  • Masonry painting

    Breathable masonry paint on prepared and stabilised walls, with cracks filled first.

The price

Rendering & Exterior Painting costs

What rendering & exterior painting costs comes down to what you actually have, not a price list. Two jobs that sound identical can be an hour of work or a week of it, which is why we do not price roofing over the phone. We come and look, then put a figure in writing.

  • Area, and how much existing render has to come off.
  • System chosen: sand and cement, or a silicone through-coloured render.
  • Whether scaffolding is needed for a full elevation.
  • Preparation, since a chalky or previously painted wall needs stabilising first.

How it works

How a rendering & exterior painting job runs

  1. Step 01

    Sound the wall

    We tap the whole elevation to find what has actually blown, which is often more than it looks.

  2. Step 02

    Quote the system

    Repair and paint, or re-render, with the difference in cost and lifespan explained.

  3. Step 03

    Prepare

    Hack off, beads on, cause of failure fixed, wall prepared and dampened as needed.

  4. Step 04

    Finish

    Render applied and finished, or paint applied in full coats, then everything cleaned down.

Questions

Rendering & Exterior Painting: common questions

The questions we get asked most often about this work. Anything else, ring and ask.

Still not sure? Ring and ask. It is usually quicker than typing it out, and you will speak to the person who would do the work.

Can you patch render rather than do the whole wall?

Yes, and for a small blown area on a side elevation that is sensible. A patch on a painted front elevation will show unless the wall is repainted, so we usually quote the patch plus a full coat of paint.

Is silicone render worth the extra?

It is through-coloured, so there is no repainting every few years, and it is more flexible than sand and cement. On a house that has cracked render and needs repainting often, it usually pays for itself.

Will painting my walls stop damp?

Not on its own, and the wrong paint makes it worse by trapping moisture. If a wall is damp we deal with the source first, then use a breathable masonry paint.

How long before new render can be painted?

Sand and cement render needs several weeks to dry and carbonate before it takes paint, and painting it too early is a common cause of flaking. A through-coloured silicone render avoids the question entirely, because it is never painted.

How often does masonry paint need redoing?

A good breathable masonry paint on properly prepared walls is commonly quoted at ten to fifteen years. The preparation decides that more than the paint does, which is why the hacking off and stabilising matter so much.
