How we handle external mastic in Little Leighs
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you have rigid filler in a joint that should flex and water getting into walls through failed joints, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Little Leighs is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
What affects the quote in Little Leighs
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- Any mould that needs treating
- The number and length of the joints
- How many areas need sealing
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Helping us quote
Before you ask for a quote, have a think about:
- The address or postcode of the job
- Pictures of the joints, sent by email
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
For external mastic in Little Leighs, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Honest limits
We will not take on work that will not last, so here’s what sealant cannot put right:
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Where we work in Little Leighs

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. For a village or hamlet like Little Leighs, 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Tell us if parking is tricky

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What external mastic looks like in Little Leighs
The South East is one of 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 look after a building such as Great Leighs Primary School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Cressing station? Then split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St John the Evangelist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
