Earley buildings and 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.
If you live in an older home near Trinity Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Earley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Earley is about 2 miles south-east of Reading, in Wokingham. Earley gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 35 towns and villages across Wokingham, large and small.

External mastic in Earley, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We work on façade panels, render & cladding joints and joints between brick and frames, and people most often call us about damp patches traced to an open external joint and movement joints with cracked, split or missing sealant.
Earley mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
Every job comes with our 12-month guarantee, wherever you are in Wokingham.

Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a family home in Earley, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Anti-fungal sanitary silicone in wet areas
- A sealant colour to suit the surroundings
- White, clear, grey or coloured to suit, where the product allows
- Neat joints and a tidy finish

Quotes for external mastic in Earley
We don’t publish a price list, because no two jobs are the same. What we look at:
- Whether the work is at height
- The number and length of the joints
- Whether there’s mould to deal with
- The number of rooms or windows
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we have said otherwise
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building. In Earley, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

FAQs for Earley
Do you cover Earley for external mastic?
Yes. We work across London and the South East, and Earley is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
What guarantee comes with external mastic in Earley?
All our work, in Earley and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How do you reach high-level joints?
Each building is different. Send us pictures and a rough idea of the height, and we will confirm what access is needed.
How long does external mastic take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. We will confirm how long when we quote.
What should I tell you?
A short description and the location. We will ask anything else we need to know.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.

What else we do in Earley
Common problems we fix in Earley
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Signs it’s time to call us include:
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
Schools such as Radstock Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
