How we handle external mastic in Little Waltham
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you have joints pointed up with cement by mistake and weeds or debris growing in open joints, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Little Waltham is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What external mastic looks like in Little Waltham
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Beaulieu Park station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Chelmer Valley High School, larger buildings have long runs of movement joint that eventually need resealing.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Little Waltham needs a little journey planning: 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 look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.

Little Waltham: your questions answered
Do you cover smaller places like Little Waltham?
Yes, Little Waltham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Beaulieu Park station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
Work for landlords, hotels and businesses
Landlords and agents in Little Waltham can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Common problems we fix in Little Waltham
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
For an older house near a landmark such as Little Waltham United Reformed Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Wash walls gently around the sealant
- Walk round the building once a year and look at the joints
- Make sure movement joints are not pointed over
- Deal with leaking gutters that soak the joints below
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
