What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Parking around Risinghurst is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

External mastic in Risinghurst, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on render & cladding joints, façade panels and copings & trims, and common reasons people get in touch are rigid filler in a joint that should flex and moss and dirt in joints with no sealant left.
Outbuildings, garages and conservatories around homes in places like Risinghurst add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Our work is backed for twelve months, in Risinghurst and everywhere else we cover.

Surface by surface
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
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Questions from Risinghurst
Can you help a landlord with a rental near Oxford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Risinghurst?
Yes. Risinghurst is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
How do I get a quote for external mastic in Risinghurst?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Quotes for external mastic in Risinghurst
Your quote is based on your job. We take into account:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Whether the work is at height
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

Aftercare tips
So the new joints stay in good condition:
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
- Don’t let climbing plants root in the sealant
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Risinghurst buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Holywell Manor (about 2.5 miles west) are a reminder that the area around Risinghurst 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.
For site and facilities teams at buildings such as Bayards Hill School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Parish Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Signs you need external mastic in Risinghurst
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
Rented homes near Oxford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
