- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
External mastic for homes and businesses in Halland
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for failed seals between different materials and rain getting behind render or cladding at a joint, on render & cladding joints, copings & trims and façade panels.
Outside joints can only be sealed when they’re dry, so work in Halland is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work comes with our one-year guarantee.

What external mastic looks like in Halland
With historic houses such as Glyndebourne (about 4.8 miles south-west) nearby, there’s older building stock in the area around Halland as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Historic houses such as Glyndebourne, about 4.8 miles south-west, show how far back building around Halland goes. Rented homes near Uckfield station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as Halland, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.

Yes. We cut out all the old sealant and clean the joint before applying anything new.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What we cannot put right
In fairness, some problems need a different trade:
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
