About our external mastic in Northbridge Street
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Typical jobs include failed sealant between panels on a façade and sealant pulling away from one side of the joint, on concrete & block, joints between brick and frames and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Northbridge Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months.

Signs you need external mastic in Northbridge Street
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Common reasons people contact us are:
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
If you live in an older home near The Parish Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Is the old sealant removed completely?
- Whether they’re fully insured
- What happens if the job turns out different
- How the joint is cleaned and prepared
When it is not the sealant
New sealant cannot fix everything, and we will tell you before we start. It won’t solve:
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How we quote for external mastic

What to tell us for a quote
When you call or email, these details help:
- Whether it has been sealed before
- How many joints, rooms or windows are involved

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Northbridge Street, 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- On commercial sites, let us know about site rules

Advice
Places near Northbridge Street
What else we do in Northbridge Street
Walls and rooflines in Northbridge Street
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Durhamford Manor (about 3.9 miles south-east) nearby, there’s older building stock in the area around Northbridge Street as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Robertsbridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Salehurst Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why it’s worth doing now in Northbridge Street
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Northbridge Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
