Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
External mastic for homes and businesses in Wildridings
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have failed seals between different materials and joints with sealant missing in places, we can help.
Outbuildings, garages and conservatories around homes in places like Wildridings add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

What else we do in Wildridings
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a job in Wildridings, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Landlords, agents and businesses in Wildridings
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When it is not the sealant
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Brickwork movement joints
Common problems we fix in Wildridings
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
People normally contact us after spotting something like this:
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
If you look after a building such as Wildridings Primary School, larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- Whether you can choose the colour
- Is VAT in the price?
Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. In an older home around Wildridings, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

Outside joints around Wildridings
Bracknell, which Wildridings is part of, is one of England’s post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Bracknell station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around St Michael and St Mary Magdalene's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Your questions about external mastic in Wildridings
Should the sealant in an older Wildridings home be renewed?
In most cases, yes, if it hasn’t been done for a while. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather.
Will you come out to Wildridings?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
