What we’re called out for in Wootton
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
The most common problems we see are:
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
Schools such as Dry Sandford Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- Are they insured?
- What the cure time is
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
About our external mastic in Wootton
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. If you are dealing with rain getting behind render or cladding at a joint and brick movement joints where the sealant has split, we can help, on copings & trims, façade panels and render & cladding joints alike.
In a village or hamlet like Wootton, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a one-year guarantee, the same in Wootton as everywhere else we work.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Walls and rooflines in Wootton
With historic houses such as Appleton Manor (about 2 miles west) nearby, there’s older building stock in the area around Wootton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Radley station, outside joints that have cracked can let damp into a rental, so check them between lets.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Have failed joints looked at early
- Leave the joints unpainted unless we’ve said otherwise
- Check external joints each spring
- Don’t let climbing plants root in the sealant
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Around Wootton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Wootton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

Common questions in Wootton
Is Wootton within the area you cover?
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.
I let a flat near Radley station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
