External mastic in Salfords
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Common call-outs are for movement joints with cracked, split or missing sealant and water getting into walls through failed joints, on façade panels, brickwork movement joints and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Salfords is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months.

Common problems we fix in Salfords
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
If you look after a building such as Salfords Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Who turns up on the day
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are 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.
Aftercare tips
Looking after new joints is easy:
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Tell anyone working on the walls about the movement joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.

What else we do in Salfords
Why it’s worth doing now in Salfords
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Salfords, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
What you get with us
- Trusted Arbo and Everbuild sealants
- A sealant colour to suit the surroundings

What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

Your questions about external mastic in Salfords
Do you cover Salfords for external mastic?

I let a flat near Salfords station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can usually cut it out and reseal it.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes anything from a few hours to several days, depending on the building. Somewhere as small as Salfords, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
