External mastic for homes and businesses in Fareham
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you have sealant that has lost its bond to the brick or render and panel joints letting water in, we can put it right, on joints between brick and frames, render & cladding joints and concrete & block alike.
Extensions are a common sight on houses around Fareham, and the joint where new wall meets old is a classic place for water to get in. Getting the joint depth right matters as much as the sealant itself.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.
Questions from Fareham
Is external mastic in a coastal place like Fareham any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
I let a flat near Fareham station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you work at height?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Outside joints around Fareham
Fareham is within about 2 miles 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. 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.
If you look after a building such as St Jude's Catholic Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St John The Evangelist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
When it is not the sealant
A few problems are outside what sealant work can do:
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave.

- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.

When to call us in Fareham
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
Common reasons people contact us are:
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
If you let a flat or house near Fareham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Whether you can choose the colour
- What preparation is included
- What happens if they find a problem under the old sealant
- How long to leave it before use
Why act early in Fareham
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. In Fareham, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

How to look after the new joints
So the new joints stay in good condition:
- Clear growth from the base of walls and joints
- Point out the joints to other trades
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
