Questions from Singleton
Is Singleton within the area you cover?
Yes, Singleton is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there a guarantee on external mastic in Singleton?
All our work, in Singleton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
About our external mastic in Singleton
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We work on façade panels, copings & trims and joints between brick and frames, and people most often call us about gaps where render, brick and frames meet and weathered mastic that no longer stretches.
External sealant needs dry, clean surfaces, so work around Singleton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
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 the bead.
What happens on the day
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Singleton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

Quotes for external mastic in Singleton
We don’t publish a price list, because jobs vary so much. What we look at:
- The type of sealant required
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Why act early in Singleton
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Singleton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What external mastic looks like in Singleton
With historic houses such as West Dean House (about 1.2 miles west) nearby, there’s older building stock in the area around Singleton as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Singleton CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What sealant work can’t fix
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
What we seal
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
What we’re called out for in Singleton
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The problems people usually mention when they call are:
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
In the older streets around The Parish Church of the Blessed Virgin Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What else we do in Singleton
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
