What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
External mastic for homes and businesses in Wyck
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. Typical jobs include weeds or debris growing in open joints and rain getting behind render or cladding at a joint, on render & cladding joints, concrete & block and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Wyck is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Do you need external mastic in Wyck?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
The problems people normally mention when they call are:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
If you let a flat or house near Alton station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- How much experience the applicator has
- Whether they’re fully insured
- How hidden problems are handled
- The length of the guarantee
Landlords, agents and businesses in Wyck
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
External mastic in Wyck: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Binsted Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Wyck
Do you work for landlords with property near Alton station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will you come out to Wyck?
Yes. Wyck is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does external mastic take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
What should I tell you?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
What affects the quote in Wyck
There’s no set price list, because jobs vary so much. The quote depends on:
- The number and length of the joints
- Whether the work is at height
- Which sealant suits the joint
- The old material and how stubborn it is
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
To help us quote quickly, let us know:
- Whether it has been sealed before
- The address or postcode of the job
- Pictures of the joints, sent by email
- Whether it’s a home or a business
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Failed render or damaged cladding panels
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Façade panels

What happens on the day
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. For a village or hamlet like Wyck, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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
- On commercial sites, let us know about site rules
- Mention any tricky access
- Let us know about parking restrictions
