How we handle external mastic in Weston

Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We are often asked to deal with hard, crazed mastic that has stopped moving and weeds or debris growing in open joints, across render & cladding joints, joints between brick and frames and concrete & block.

Houses in smaller places like Weston can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Parking around Weston is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in

Advice

Weston questions

Will you come out to Weston?

Yes, Weston is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Does the coastal weather in Weston affect outside sealant?

Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.

How long will you be here?

Most jobs take a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.

Do you have insurance?

Yes. We’re fully insured.

What do you put in the joint?

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.

Do you work for letting agents?

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Weston buildings and the weather

Weston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Homes close to Holy Trinity Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Sholing station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Weston Shore Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Different surfaces, different methods

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly.

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

Why deal with it now?

The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. Homes in smaller places like Weston can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

How we quote for external mastic

We do not publish a price list, because jobs vary so much. What we look at:

  • The old material and how stubborn it is
  • The type of sealant required
  • Any working-time requirements on site
  • The size of the job

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • The type of property

Want a quote for external mastic? Please ring 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

Work for landlords, hotels and businesses

If you manage several properties in or around Weston, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Looking after it afterwards

After the cure time, these simple habits help:

  • Walk round the building once a year and look at the joints
  • Avoid pressure-washing directly into sealant joints
  • Leave the joints unpainted unless we have said otherwise
  • Deal with leaking gutters that soak the joints below

Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.

Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
