External mastic for homes and businesses in Trumps Green
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. If you have joints pointed up with cement by mistake and water getting into walls through failed joints, we can help.
Outside joints can only be sealed when they’re dry, so work in Trumps Green is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
You get a 12-month guarantee, the same in Trumps Green as everywhere else we work.

FAQs for Trumps Green
Is Trumps Green within the area you cover?
Yes, Trumps Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Virginia Water station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Are you insured?
Yes. We are fully insured.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Trumps Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Signs you need external mastic in Trumps Green
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Signs it’s time to call us include:
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
In the older streets around Christ Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Which sealant they’ll use, and why
- What the quote includes, VAT included or not
- What the cure time is
- Are they insured?
How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Trumps Green buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Botleys Mansion (about 2.2 miles south-east) nearby, there’s older building stock in the area around Trumps Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Virginia Water station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Trumps Green Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
