How we handle external mastic in Ringmer
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have joints where the bead has come unstuck and gaps where render, brick and frames meet, we can put it right, on copings & trims, concrete & block and brickwork movement joints alike.
Houses in smaller places like Ringmer can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
Each job carries a 12-month guarantee, whatever its size.

- Access, such as stairs, a lift or height

Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Landlord and commercial work in Ringmer
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Why act early in Ringmer
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Around Ringmer, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Outside joints around Ringmer
With historic houses such as Glyndebourne (about 1.1 miles south) nearby, there’s older building stock in the area around Ringmer 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near The Parish Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Ringmer Primary and Nursery School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Glynde station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Your questions about external mastic in Ringmer
Is Ringmer within the area you cover?
Yes. Ringmer is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Glynde station. Can you help?

Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
Where is Mr Mastic based?
We work from Crawley. We cover Ringmer and the rest of East Sussex.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
The process
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. A visit to Ringmer is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Let us know about stairs, lifts or work at height
