How we handle external mastic in Watermead
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include movement joints filled with mortar instead of sealant and sealant that has lost its bond to the brick or render, on joints between brick and frames, concrete & block and brickwork movement joints.
In a smaller place like Watermead, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
There’s a 12-month guarantee on every job.

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. For a job in Watermead, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- 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.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on the first splits you see
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a smaller place like Watermead, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- We never seal over old sealant
- Experience in homes, commercial sites and hotels
- Every job guaranteed for a year
- Colour agreed with you before work begins

What external mastic looks like in Watermead

For landlords with property near Aylesbury station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St James include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

When to call us in Watermead
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Weathered mastic that no longer stretches
- Panel joints letting water in
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
Schools such as St Louis Catholic Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Before you book anyone
- How hidden problems are handled
- Whether they’re fully insured
- Is the old sealant removed completely?
- Whether VAT is included

We also work for property managers and facilities teams. We can quote a run of properties together.
For anyone letting property in or around Watermead, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Can I do it myself?
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. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
