External mastic in Wrabness
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. We work on joints between brick and frames, concrete & block and render & cladding joints, and the jobs we see most are movement joints filled with mortar instead of sealant and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in Wrabness is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Common questions in Wrabness
Is external mastic in a coastal place like Wrabness any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Is Wrabness within the area you cover?
Yes. Wrabness 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.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. In a small place like Wrabness, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit usually 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.

What else we do in Wrabness
Outside joints around Wrabness
Wrabness is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
In the older streets around Parish Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Do you need external mastic in Wrabness?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Weeds or debris growing in open joints
- Gaps where render, brick and frames meet
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
Rented homes near Wrabness station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Who does the work, and how experienced they are
- Is VAT in the price?
- What happens if the job turns out different
- What product goes in the joint
How to look after the new joints
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Wrabness, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
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.
