External & façade joints in Grove Green, Kent
Movement joints in Grove Green need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

- Joints pointed up with cement by mistake
How we handle external mastic in Grove Green
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on render & cladding joints, concrete & block and façade panels, and people most often call us about weeds or debris growing in open joints and sealant that has lost its bond to the brick or render.
In and around Grove Green, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Walls and rooflines in Grove Green
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Stoneacre (about 2.5 miles south-east) are a reminder that the area around Grove Green has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

We also work for property managers and facilities teams in Grove Green and across Kent. Several sites can go on one quote, and we’re fully insured for the work.
Surface by surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
FAQs for Grove Green
Do you cover Grove Green for external mastic?
Yes. Our work covers London and the South East, and Grove Green is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
I let a flat near Bearsted station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We’ll reseal it with a flexible sealant.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
When to call us in Grove Green
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint.
Keep an eye out for any of the following:
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Brick movement joints where the sealant has split
If you live in an older home near Church of St Luke, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Are they insured?
- Whether all the old sealant comes out first
- What guarantee comes with the work
- What preparation is included
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. A visit to Grove Green is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Clear growth from the base of walls and joints
- Keep movement joints as flexible joints, not mortar
- Act on the first splits you see
- Keep water from gutters off the wall
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
What we can’t put right
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
