About our external mastic in Dippenhall
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 so the joint does not stand out. We work on joints between brick and frames, concrete & block and façade panels, and common reasons people get in touch are moss and dirt in joints with no sealant left and weathered mastic that no longer stretches.
Somewhere as small as Dippenhall, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, it’s backed by our one-year guarantee in Dippenhall and across Surrey.

Outside joints around Dippenhall
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Farnham Castle (about 1.4 miles east) are a reminder that the area around Dippenhall has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as St Francis, 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 Potters Gate CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What else we do in Dippenhall
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Dippenhall needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us about any water getting in
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Related advice
Common problems we fix in Dippenhall
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Signs it’s time to call us include:
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
- Rain getting behind render or cladding at a joint
If you let a flat or house near Farnham station, outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Keep high-pressure jets off the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
FAQs for Dippenhall
Do you cover Dippenhall for external mastic?
Yes. We work across London and the South East, and Dippenhall is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is Dippenhall within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What information do you need?
Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Dippenhall, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
