The process

We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Wanborough needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in
  • Mention any sign-in or site rules at work premises

Advice

How we handle external mastic in Wanborough

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you’re dealing with sealant that has lost its bond to the brick or render and water getting into walls through failed joints, we can put it right, whatever the surface.

Outside joints can only be sealed when they’re dry, so work in Wanborough is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Show decorators and builders where the movement joints are
  • Fix overflowing gutters above sealed joints
  • Leave the joints unpainted unless we’ve said otherwise
  • Keep high-pressure jets off the joints

Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Why it’s worth doing now in Wanborough

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Wanborough can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Quotes for external mastic in Wanborough

We do not publish a price list. The quote depends on:

  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with
  • The size of the job
  • Working hours on commercial sites

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

What to tell us for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • What’s wrong with the joints now
  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • The rough size of the job

If you are in Wanborough and need external mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Walls that need new movement joints cut into them
  • Cracked brickwork or render that needs a builder or plasterer
  • Subsidence or other structural problems

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Questions from Wanborough

I let a flat near Wanborough station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.

Is Wanborough in your area for external mastic?

Yes. Our work covers London and the South East, and Wanborough is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Can you do several jobs on one visit?

Yes. Just list everything you need and we will quote it together.

Why do you put foam in the joint first?

The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.

What’s an expansion joint in brickwork?

A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

How long should I leave it?

Cure times vary by product. We tell you how long to leave it before we go.

Different surfaces, different methods

Concrete and blockwork

Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.

Render joints

Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

External mastic in Wanborough: local notes

Historic houses like Wanborough Manor (about 0.1 miles east) are a reminder that the area around Wanborough has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In the older streets around Church of St Bartholomew, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Wanborough station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Do you need external mastic in Wanborough?

If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.

Any of these means the joints need attention:

  • Failed sealant between panels on a façade
  • Gaps where render, brick and frames meet
  • Movement joints filled with mortar instead of sealant
  • Rain getting behind render or cladding at a joint

Schools such as Puttenham CofE Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What your quote should include

  • Whether you can choose the colour
  • How much experience the applicator has
  • What preparation is included
  • When the joint can take water or movement
