About our external mastic in Laleham
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. If you are dealing with joints pointed up with cement by mistake and cracked joints where brick meets render or frames, we can help.
Homes around Laleham range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

What external mastic looks like in Laleham
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. With historic houses such as Botleys Mansion (about 3.4 miles south-west) nearby, there’s older building stock in the area around Laleham 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.
In the older streets around Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Staines station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What we’re called out for in Laleham
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Failed seals between different materials
- Panel joints letting water in
For site and facilities teams at buildings such as Laleham CofE VA Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Questions from Laleham
Will you come out to Laleham?
Yes. Laleham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Staines station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months.
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.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure movement joints aren’t pointed over
- Keep high-pressure jets off the joints
- Have failed joints looked at early
- Clear growth from the base of walls and joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It usually takes a few hours to a few days, depending on the length of joint and the access. For a job in Laleham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the quote in Laleham
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The size of the job
- The product the joint needs
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
What to tell us for a quote
To help us quote quickly, please include:
- How we’d reach the joints
- If someone has resealed it before
- Roughly how big the job is
- Whether it’s a home or a business
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
