Common questions in Town Row
Can you do external mastic in Town Row?
Yes. We work across London and the South East, and Town Row is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Town Row?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Do you have insurance?
Yes. Full insurance covers our work.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
About our external mastic in Town Row
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. Typical jobs include joints where the bead has come unstuck and plants rooting in failed movement joints, across concrete & block, joints between brick and frames and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Town Row is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard.

Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Show decorators and builders where the movement joints are
- Get split or bare joints resealed while the damage is small
- Make sure movement joints are not pointed over
- Leave the joints unpainted unless we’ve said otherwise
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.

What affects the quote in Town Row
The price is agreed before any work begins. It takes into account:
- The size of the job
- Any working-time requirements on site
- The number of rooms or windows
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
What external mastic looks like in Town Row
With historic houses such as Wadhurst Castle (about 4.4 miles east) nearby, there’s older building stock in the area around Town Row 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to The Parish Church of St Denys include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Rotherfield Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Crowborough station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Town Row, access is generally 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.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

Leave it or put it right?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Where a wall is exposed, as many are in small places like Town Row, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

DIY versus a professional finish
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
