How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
About our external mastic in Woolton Hill
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on copings & trims, brickwork movement joints and render & cladding joints, and common reasons people get in touch are gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving.
Outside joints can only be sealed when they’re dry, so work in Woolton Hill is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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 does not work out, we can still put it right.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Leave the joints unpainted unless we have said otherwise
- Keep water from gutters off the wall
- Point out the joints to other trades
- Get split or bare joints resealed while the damage is small
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Your questions about external mastic in Woolton Hill
Do you cover Woolton Hill for external mastic?
Yes. Our work covers London and the South East, and Woolton Hill is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Woolton Hill?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you insured?
Yes. We’re fully insured.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What is backing rod for?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Woolton Hill buildings and the weather
Historic houses like Stargroves (about 1.6 miles west) are a reminder that the area around Woolton Hill has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Thomas, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Newbury station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Woolton Hill Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Why act early in Woolton Hill
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Woolton Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
