About our external mastic in Roughway
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. If you are dealing with joints where the bead has come unstuck and failed seals between different materials, we can put it right.
External sealant needs dry, clean surfaces, so work around Roughway is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, large or small.

Questions from Roughway
Can you do external mastic in Roughway?
Yes. Our work covers London and the South East, and Roughway is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Borough Green & Wrotham station?
Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
What external mastic looks like in Roughway
Historic houses like Old Soar Manor (about 0.7 miles north) are a reminder that the area around Roughway has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Historic houses such as Old Soar Manor, about 0.7 miles north, show how far back building around Roughway goes. For site and facilities teams at buildings such as Hadlow Rural Community School, its movement joints, gutters and trims need looking after like any other building’s.

When to call us in Roughway
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
Rented homes near Borough Green & Wrotham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Why it’s worth doing now in Roughway
A low-modulus sealant is chosen because it moves without pulling hard at the 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. Around Roughway, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

How to look after the new joints
To keep the joints looking good and working properly:
- Make sure movement joints aren’t pointed over
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
What happens on the day
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Roughway, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
