How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like South Heath, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.

Window mastic in South Heath: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Thorpe Hall (about 4.2 miles east) nearby, there’s older building stock in the area around South Heath as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

For site and facilities teams at buildings such as Colne Community School and College, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in South Heath
Is South Heath in your area for window mastic?
Yes, South Heath is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Great Bentley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Where are you based?
We work from Crawley. Our applicators cover South Heath, along with the rest of our area.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
Looking after it afterwards
Looking after new joints is easy:
- Walk round the house once a year and look at the joints
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like South Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.
