What affects the cost of external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- The type of sealant required
- How easy the joints are to reach
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Before you ask for a quote, have a think about:
- Photos by email, if that’s easy

- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work

External mastic in Wix Green
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on brickwork movement joints, render & cladding joints and copings & trims, and common reasons people get in touch are moss and dirt in joints with no sealant left and damp patches traced to an open external joint.
External sealant needs dry, clean surfaces, so work around Wix Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a one-year guarantee.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Walls and rooflines in Wix Green
Wix Green is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Thorpe Hall (about 4.2 miles south) nearby, there’s older building stock in the area around Wix 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 Wrabness station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Wix and Wrabness Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Wix Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Wix Green: your questions answered
Do you work for landlords with property near Wrabness station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Wix Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How long should I leave it?
Cure times vary by product. We tell you how long to leave it before we go.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. In a small place like Wix Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive

What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
