Russell's Green External Mastic
Problem with your movement joints in Russell's Green? We cut out the old, prepare the joints and apply the right sealant.

- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
How we handle external mastic in Russell's Green
On houses, flats and commercial buildings across Russell's Green, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We are often asked to deal with movement joints filled with mortar instead of sealant and failed sealant between panels on a façade, on façade panels, copings & trims and brickwork movement joints.
Around Russell's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Render that’s blown, hollow or coming away
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Somewhere like Russell's Green 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.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.

Advice
How we quote for external mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether the work is at height
- When we can work, for business premises
- The product the joint needs
- The number of rooms or windows
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Asking for a quote
Before you ask for a quote, have a think about:
- The type of property
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Why act early in Russell's Green
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. In a small place like Russell's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- Experience in homes, commercial sites and hotels
- A 12-month guarantee on all work
- Tidy, careful work
- We never seal over old sealant
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
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. Early work is quicker and leaves a better finish.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
External mastic in Russell's Green: local notes
Russell's Green is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Ninfield Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Cooden Beach station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Your questions about external mastic in Russell's Green
Do you cover smaller places like Russell's Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Cooden Beach station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
