About our external mastic in Stonegate
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We work on copings & trims, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint.
Somewhere as small as Stonegate, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, in Stonegate and everywhere else we cover.

FAQs for Stonegate
Will you come out to Stonegate?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Stonegate in your area for external mastic?
Yes. Our work covers London and the South East, and Stonegate is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move.
What sealant work can’t fix
We will always be straight with you, so here’s what new sealant will not do:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Damp that isn’t coming from the joint
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Walls and rooflines in Stonegate
London and the South East are among 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 Wadhurst Castle (about 3 miles north-west) nearby, there’s older building stock in the area around Stonegate 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.
In the older streets around Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Stonegate Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Stonegate station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Stonegate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Have failed joints looked at early
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
- Make sure movement joints are not pointed over
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
