Why it’s worth doing now in Manwood Green
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. Around Manwood Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

About our external mastic in Manwood Green
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. If you have sealant that has lost its bond to the brick or render and joints pointed up with cement by mistake, we can put it right.
Older homes in small places like Manwood Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
To keep the joints looking good and working properly:
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What external mastic looks like in Manwood Green
Rainfall in the South East is lower than in much 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 Barrington Hall (about 3.3 miles north) nearby, there’s older building stock in the area around Manwood Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Sawbridgeworth station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Martin include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.

What else we do in Manwood Green
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. In a small place like Manwood Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Tell us if parking is tricky
