How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere as small as Polstead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.

Advice
About our external mastic in Polstead
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We are often asked to deal with joints pointed up with cement by mistake and brick movement joints where the sealant has split, on façade panels, joints between brick and frames and copings & trims.
External sealant needs dry, clean surfaces, so work around Polstead is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our one-year guarantee in Polstead and across Essex.

Polstead questions
Is external mastic in Polstead guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Polstead for external mastic?
Yes. We work across London and the South East, and Polstead is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What the job involves on each 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.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Walls and rooflines in Polstead
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. In and around Polstead, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Structural movement, which needs a surveyor or engineer
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal

- Brickwork movement joints
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash walls gently around the sealant
- Ask before painting over external sealant
- Check external joints each spring
- Keep water from gutters off the wall
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.

- How easy the joints are to reach
