About our external mastic in Paley Street
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, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for failed seals between different materials and water getting into walls through failed joints, on concrete & block, brickwork movement joints and copings & trims.
In a village or hamlet like Paley Street, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months.

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Paley Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

What external mastic looks like in Paley Street
With historic houses such as Dorney Court (about 3.8 miles north-east) nearby, there’s older building stock in the area around Paley Street as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Maidenhead station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Dorney Court, about 3.8 miles north-east, is one of the historic houses in the wider area around Paley Street, and older homes nearby need a sealant that suits their walls.

What else we do in Paley Street

- Subsidence or other structural problems

How we quote for external mastic
You will get a clear quote before work begins. It takes into account:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Access and height
- The product the joint needs
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Photos by email, if that’s easy
We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
What we’re called out for in Paley Street
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
These are the problems we’re asked about most:
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
Schools such as Holyport College are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
- What insurance they hold
- What preparation is included
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
FAQs for Paley Street
Is Paley Street within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Paley Street for external mastic?
Yes. Our work covers London and the South East, and Paley Street is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
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.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
