Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
External mastic in Goddards Green
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on façade panels, concrete & block and copings & trims, and the jobs we see most are panel joints letting water in and weeds or debris growing in open joints.
In a village or hamlet like Goddards Green, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Goddards Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

What’s an expansion joint in brickwork?
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 I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
What we cannot put right
Before booking, it’s worth knowing the limits:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Concrete & block
- Façade panels
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Why act early in Goddards Green
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Goddards Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before work begins.

Walls and rooflines in Goddards Green
With historic houses such as Ockenden Manor (about 3 miles north-east) nearby, there’s older building stock in the area around Goddards Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St Edward the Confessor include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Burgess Hill station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as St Paul's Catholic College, its movement joints, gutters and trims need looking after like any other building’s.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
