What external mastic looks like in Laughton
With historic houses such as Glyndebourne (about 3.4 miles south-west) nearby, there’s older building stock in the area around Laughton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you let a flat or house near Glynde station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to The Parish Church of All Saints include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we handle external mastic in Laughton
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on copings & trims, concrete & block and façade panels, and common reasons people get in touch are old sealant gone brittle and cracked and sealant that has lost its bond to the brick or render.
In a village or hamlet like Laughton, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Landlord and commercial work in Laughton
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Laughton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Quotes for external mastic in Laughton
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Which sealant suits the joint
- Whether the work is at height
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own. Simply call 0345 464 0079 or send us an email and describe the job and send pictures if you have them.
Common problems we fix in Laughton
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
These are the problems we are asked about most:
- Damp patches traced to an open external joint
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
Managing a site like Laughton Community Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Which colour the sealant will be
- What insurance they hold
- Whether they seal over old material or remove it
- How hidden problems are handled
Laughton questions
Will you come out to Laughton?
Yes, Laughton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Laughton for external mastic?
Yes, Laughton is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Are you insured?
Yes. Full insurance covers our work.
Do you use backing rod?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Different surfaces, different methods
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
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.
