How we quote for external mastic
Your quote is based on your job. We take into account:

- Access and height
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
Helping us quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- Whether it has been sealed before
- Roughly how big the job is
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
External mastic in Shellwood Cross
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, concrete & block and render & cladding joints, and the jobs we see most are cracked joints where brick meets render or frames and weathered mastic that no longer stretches.
Around Shellwood Cross, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
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.

Landlord and commercial work in Shellwood Cross
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building. Somewhere like Shellwood Cross needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

What we are called out for in Shellwood Cross
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
The most common problems we see are:
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
- Gaps where render, brick and frames meet
If you live in an older home near Church of St Bartholomew, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- Whether they seal over old material or remove it
- What product goes in the joint
- Is VAT in the price?
- What happens if the job turns out different
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we can’t put right
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Movement that is more than a sealant joint can take
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
Joints and surfaces we work on
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames

What external mastic looks like in Shellwood Cross
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.
Rented homes near Holmwood station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Shellwood Cross
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Around Shellwood Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Common questions in Shellwood Cross
Will you come out to Shellwood Cross?
Yes, Shellwood Cross is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Shellwood Cross in your area for external mastic?
Yes. We work across London and the South East, and Shellwood Cross is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
