How we handle external mastic in Thorley Street

We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We work on brickwork movement joints, render & cladding joints and copings & trims, and common reasons people get in touch are sealant that has lost its bond to the brick or render and movement joints with cracked, split or missing sealant.

Outside joints can only be sealed when they’re dry, so work in Thorley Street is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Thorley Street buildings and the weather

Thorley Street is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Homes close to St. Swithin's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. In and around Thorley Street, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Thorley Street is about 6 miles south-east of Lymington, in the Isle of Wight.

How the visit works

There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building from start to finish. In a small place like Thorley Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

How to prepare

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height

Common questions in Thorley Street

Does the coastal weather in Thorley Street affect outside sealant?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

Is Thorley Street within the area you cover?

Yes, Thorley Street is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

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.

Can you seal over the old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Will the new joint stand out?

The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins.

Why deal with it now?

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Around Thorley Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

How to look after the new joints

After the cure time, these simple habits help:

  • Keep movement joints as flexible joints, not mortar
  • Keep water from gutters off the wall
  • Have failed joints looked at early
  • Clear growth from the base of walls and joints

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

Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

Surface by surface

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

Render joints

Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
