How we handle external mastic in Church Town
For buildings in Church Town, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on copings & trims, façade panels and render & cladding joints, and people most often call us about joints where the bead has come unstuck and movement joints with cracked, split or missing sealant.
Somewhere as small as Church Town, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All our work comes with a one-year guarantee, wherever you are in Surrey.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
Different surfaces, different methods
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 walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Church Town, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Looking after it afterwards
To keep the joints looking good and working properly:
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the quote in Church Town
Call for a quick quote. What matters most is:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- The number of rooms or windows
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- If someone has resealed it before
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job.
Landlord and commercial work in Church Town
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

When it isn’t the sealant
In fairness, some problems need a different trade:
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Outside joints around Church Town
Historic houses like Titsey Place (about 3.8 miles north-east) are a reminder that the area around Church Town 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.
For an older house near a landmark such as Church of St Nicholas, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Godstone Village School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Godstone station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
