External & façade joints in Brightling, East Sussex
We cover Brightling for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
How we handle external mastic in Brightling
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have damp patches traced to an open external joint and hard, crazed mastic that has stopped moving, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Brightling is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, large or small.

Common problems we fix in Brightling
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
People normally contact us when they notice one of these:
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
If you live in an older home near The Parish Church of St Thomas A Becket, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- What the quote includes, VAT included or not
What affects the quote in Brightling
You will get a clear quote before work begins. It’s based on:
- When we can work, for business premises
- The size of the job
- Access and height
- Whether there’s mould to deal with
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- What’s wrong with the joints now
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Landlord and commercial work in Brightling
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Façade panels

- Concrete & block
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

What happens if it’s left?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Brightling, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Brightling: your questions answered
Will you come out to Brightling?
Yes, we do. 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.
Is Brightling in your area for external mastic?
Yes. We work across London and the South East, and Brightling is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes anything from a few hours to several days, depending on the building. In a small place like Brightling, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- 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
- Keep children and pets away from the work area
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Outside joints around Brightling
With historic houses such as Bateman's (about 1.9 miles north-west) nearby, there’s older building stock in the area around Brightling 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Robertsbridge station, outside joints that have cracked can let damp into a rental, so check them between lets.
