DIY sealant or a professional job?
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 call for the right materials, safe access and experience.
How we handle external mastic in Rettendon
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We’re often asked to deal with weathered mastic that no longer stretches and sealant pulling away from one side of the joint, on brickwork movement joints, façade panels and concrete & block.
External sealant needs dry, clean surfaces, so work around Rettendon is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee.

What affects the quote in Rettendon
The quote reflects the job in front of us. We look at:
- Whether the work is at height

- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
Asking for a quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
What external mastic looks like in Rettendon
Historic houses like Danbury Place (about 4.2 miles north) are a reminder that the area around Rettendon has older buildings as well as new. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Danbury Place, about 4.2 miles north, is one of the historic houses in the wider area around Rettendon.

How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Rettendon, 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Advice
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Rettendon, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Do you need external mastic in Rettendon?
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
- Panel joints letting water in
Letting a property close to Battlesbridge station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- Who turns up on the day
- Whether they’re fully insured
- How long to leave it before use
- The length of the guarantee
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Rettendon: your questions answered
I let a flat near Battlesbridge station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is Rettendon within the area you cover?
Yes, Rettendon is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How do I get a quote for external mastic in Rettendon?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint does not draw the eye.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
