External & façade joints in Highcliffe, Hampshire
Problem with your movement joints in Highcliffe? We remove the old material, prepare the joints and seal them properly.
- Leaking joints around cladding and façade panels
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Homes in smaller places like Highcliffe can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Signs you need external mastic in Highcliffe
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
The problems people usually mention when they call include:
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
Managing a site like All Saints Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Are they insured?
- The length of the guarantee
- Whether all the old sealant comes out first
- How much experience the applicator has
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
How it works
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Highcliffe, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Common questions in Highcliffe
Do you cover Highcliffe for external mastic?
Yes. We work across London and the South East, and Highcliffe is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Winchester station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the building. We will tell you when we quote.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Should I point up the gap in my brickwork?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.

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 All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Winchester station, split movement joints are easy to miss on a rental until damp shows inside.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Check external joints each spring
- Act on the first splits you see
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead 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.
