External mastic in Wokingham

External mastic in Wokingham

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’s needed to reach them safely. We work on brickwork movement joints, render & cladding joints and copings & trims, and the jobs we see most are joints where the bead has come unstuck and weeds or debris growing in open joints.

Wokingham has everything from period brickwork to modern rendered and clad buildings. Newer buildings rely on sealed movement joints, while older ones need their gutters, fascias and trims kept tight.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Keep movement joints as flexible joints, not mortar
  • Keep water from gutters off the wall
  • Ask before painting over external sealant
  • Get split or bare joints resealed while the damage is small

Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.

Wokingham: your questions answered

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

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

What guarantee comes with external mastic in Wokingham?

All our work, in Wokingham and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

When will the joints need doing again?

There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.

Do you work in Wokingham?

Yes, we do. Wokingham is part of the area we cover, and the service is the same as everywhere else.

Can you seal joints between two different materials?

Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.

What colours does the sealant come in?

There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.

Can new sealant go over the old?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

What we can’t put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Movement that is more than a sealant joint can take
  • Rising or penetrating damp from elsewhere in the wall

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

What we seal

  • Concrete & block
  • Brickwork movement joints
  • Copings & trims
  • Render & cladding joints
  • Joints between brick and frames
  • Façade panels

Landlord and commercial work in Wokingham

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.

What we are called out for in Wokingham

Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.

The most common problems we see are:

  • Plants rooting in failed movement joints
  • Failed seals between different materials
  • Sealant that has lost its bond to the brick or render
  • Hard, crazed mastic that has stopped moving

Homes close to Church of St Paul include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Our hiring checklist

Leave it or put it right?

An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. For landlords in Wokingham, failed sealant soon turns into tenant complaints about mould, damp or draughts. Sorting it between tenancies is easier than dealing with it mid-let.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What you get with us

  • Colour picked to suit the job
  • An ARBOMaster approved applicator
  • Experience in homes, commercial sites and hotels
  • Arbo and Everbuild products

How we quote for external mastic

We quote each job individually. These are the things that affect it:

  • The type of sealant required
  • The size of the job
  • When we can work, for business premises
  • How easy the joints are to reach

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we need to know

What to tell us when you ask for a quote:

  • How we’d reach the joints
  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or send us an email.

How it works

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the building. Commercial jobs in Wokingham can be planned out of hours where a building cannot close, while home visits are arranged within our normal working hours, Monday to Saturday.

  1. We start by walking round the building and agreeing the joints and the access.
  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.

How to prepare

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear items away from the joints we are working on
