External mastic for homes and businesses in Mousehill
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on façade panels, render & cladding joints and brickwork movement joints, and the jobs we see most are movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving.
Outside joints can only be sealed when they’re dry, so work in Mousehill is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
Why act early in Mousehill
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Mousehill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

What the job involves on each surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Mousehill questions
Can you help a landlord with a rental near Milford (Surrey) station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Mousehill within the area you cover?
Yes, Mousehill is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Do you guarantee your work?
Yes. All our work carries our one-year guarantee.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
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 getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Do you need external mastic in Mousehill?
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
Signs it’s time to call us include:
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
For site and facilities teams at buildings such as Milford School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Who does the work, and how experienced they are
- What the cure time is
- Which colour the sealant will be
- What insurance they hold
Walls and rooflines in Mousehill
With historic houses such as Loseley Park (about 3.8 miles north-east) nearby, there’s older building stock in the area around Mousehill 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Milford (Surrey) station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around St John the Evangelist's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
