Your questions about external mastic in Hythe End
Can you do external mastic in Hythe End?
Yes. Our work covers London and the South East, and Hythe End is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
I let a flat near Wraysbury station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will tell you how long to expect.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
External mastic in Hythe End
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. Typical jobs include joints with sealant missing in places and sealant pulling away from one side of the joint, across joints between brick and frames, façade panels and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Hythe End 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, so you’re not left on your own once the job is done.

Why it’s worth doing now in Hythe End
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Hythe End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the building from start to finish. For a village or hamlet like Hythe End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Common problems we fix in Hythe End
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Signs it’s time to call us include:
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
Letting a property close to Wraysbury station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- How long to leave it before use
- What happens if they find a problem under the old sealant
- The length of the guarantee
- What insurance they hold
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Tell anyone working on the walls about the movement joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Hythe End buildings and the weather
Historic houses like Frogmore House (about 3.2 miles north-west) are a reminder that the area around Hythe End has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St John's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Strode's College? Then larger buildings have long runs of movement joint that eventually need resealing.
