Why act early in Pyrford Green
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Around Pyrford Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

External mastic in Pyrford Green
On houses, flats and commercial buildings across Pyrford 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. Typical jobs include gaps where render, brick and frames meet and brick movement joints where the sealant has split, across joints between brick and frames, render & cladding joints and concrete & block.
Older homes in small places like Pyrford Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Whether the work is at height
- The number of rooms or windows
- Whether there’s mould to deal with
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before we start.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- The address or postcode of the job
- A few pictures by email, if you can
- If someone has resealed it before
- What’s wrong with the joints now
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
When it is not the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- 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
- Movement that is more than a sealant joint can take
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Where we work in Pyrford Green

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere like Pyrford Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Signs you need external mastic in Pyrford Green
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Water getting into walls through failed joints
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
Schools such as Pyrford Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- How the colour is chosen
- Who turns up on the day
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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, and the work is guaranteed for a year.
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
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.
Questions from Pyrford Green
Do you cover Pyrford Green for external mastic?
Yes. We work across London and the South East, and Pyrford Green is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Is Pyrford Green within the area you cover?
Yes, we do. 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.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Pyrford Green buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Byfleet Manor (about 1.7 miles north-east) are a reminder that the area around Pyrford Green has older buildings as well as new. 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 West Byfleet station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Nicholas's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
