How we handle external mastic in Barton Stacey
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you are dealing with sealant pulling away from one side of the joint and joints pointed up with cement by mistake, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Barton Stacey is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same 12-month guarantee in Barton Stacey and across Hampshire.

Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.

How to look after the new joints
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
- Don’t let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Common problems we fix in Barton Stacey
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Damp patches traced to an open external joint
For an older house near a landmark such as Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Common questions in Barton Stacey
Can you help a landlord with a rental near Micheldever station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you do external mastic in Barton Stacey?
Yes, Barton Stacey is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What affects the cost of external mastic
The quote reflects the job in front of us. We take into account:
- Any mould that needs treating
- The number and length of the joints
- Access and height
- The old material and how stubborn it is
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Photos help, but a description is a good start. Try to tell us:
- A few pictures by email, if you can
- Where the property is
- Roughly how big the job is
- Any previous sealing or DIY work
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
