External mastic in Wolverton, done properly

We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. We work on joints between brick and frames, render & cladding joints and façade panels, and the jobs we see most are rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint.

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

Big or small, it’s backed by our 12-month guarantee.

Surface by surface

Brickwork movement joints

Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.

Wolverton questions

Does the coastal weather in Wolverton affect outside sealant?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

Do you cover smaller places like Wolverton?

Yes. Wolverton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you work on commercial sites?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

How often do external joints need resealing?

That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.

How long does external mastic take?

A typical job takes anything from a few hours to several days, depending on the building, including the preparation. Your quote will say how long we expect yours to take.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you when we finish.

How to look after the new joints

How long the joints last depends on use and care. Here’s what we suggest:

Keep high-pressure jets off the joints
Keep soil, plants and ivy away from the joints
Get split or bare joints resealed while the damage is small
Leave the joints unpainted unless we have said otherwise

Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.

Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

Wolverton buildings and the weather

Wolverton is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 Church of St Anthony the Martyr include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Astor College for the Arts, its movement joints, gutters and trims need looking after like any other building’s.

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 near the open joint, so the damage spreads beyond the joint. Around Wolverton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

For landlords and businesses

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

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

What we do, step by step

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Wolverton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

First we look over the joints with you, agree which to renew and talk through access.
Old sealant and any debris are cut and raked out.
Both sides are cleaned back to sound material and primed if needed.
Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

For indoor joints, keep the area dry beforehand if you can
Mention any sign-in or site rules at work premises
Tell us about any water getting in
