About external mastic in West Berkshire

Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on concrete & block, copings & trims and brickwork movement joints, and the jobs we see most are cracked joints where brick meets render or frames and rain getting behind render or cladding at a joint.

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building.

We start by walking round the building and agreeing the joints and the access.
We cut out the old mastic and rake out anything in the joint.
The faces are brushed clean and primed where the product requires it.
We fit closed-cell backing rod to control the depth.
The exterior sealant is applied, tooled and checked along its length.

Nearby too are The Diamond Tap (within half a mile north-east), St Nicolas C.E. Junior School (within half a mile south) and St Bartholomew's School (0.6 miles south-west).

Not far away are Audrey's Meadow.

Walls and rooflines across West Berkshire

West Berkshire has everything from period brickwork to rendered and clad modern buildings. The joints between different materials are the usual weak points.

The South East is one of the drier parts of the UK, but outdoor sealant still needs a dry day and clean surfaces, so outside work in West Berkshire is planned around the forecast.

Newbury: If you live in an older home near St Nicolas Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as St Nicolas C.E. Junior School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Quotes for external mastic in West Berkshire

We do not publish a price list, because no two jobs are the same. The quote depends on:

The product the joint needs
Whether old sealant or filler has to be cut out
Any mould that needs treating
The number of rooms or windows

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

The rough size of the job
How we’d reach the joints
Where the property is
A few photos by email, if you can

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Should I try it myself first?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Landlord and commercial work in West Berkshire

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

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

Why it fails

Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.

Common reasons people contact us include:

Joints where the bead has come unstuck
Plants rooting in failed movement joints
Movement joints filled with mortar instead of sealant
Panel joints letting water in

How the job changes by surface

Joints between dissimilar materials

Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.

West Berkshire: your questions answered

What is backing rod for?

Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme.

How often do external joints need resealing?

That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.

Do you work for letting agents?

Yes. Domestic, commercial and hotel work are all part of what we do.

Can you reach joints on upper floors?

It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.

How long does external mastic take?

It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
