External mastic for homes and businesses in Hascombe
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Common call-outs are for failed seals between different materials and rain getting behind render or cladding at a joint, on brickwork movement joints, façade panels and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Hascombe is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, it’s backed by our 12-month guarantee in Hascombe and across Surrey.

Why it’s worth doing now in Hascombe
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Hascombe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Do you need external mastic in Hascombe?
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Keep an eye out for these signs:
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
Homes close to Church of St Peter include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.

Outside joints around Hascombe
With historic houses such as Loseley Park (about 4.8 miles north) nearby, there’s older building stock in the area around Hascombe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Milford (Surrey) station, outside joints that have cracked can let damp into a rental, so check them between lets.
