Uxbridge: your questions answered
Is Uxbridge within the area you cover?
Yes. Uxbridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Uxbridge for external mastic?
Yes. Our work covers London and the South East, and Uxbridge is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together.
How we handle external mastic in Uxbridge
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Common call-outs are for damp patches traced to an open external joint and gaps where render, brick and frames meet, across joints between brick and frames, façade panels and render & cladding joints.
Outbuildings, garages and conservatories around homes in places like Uxbridge add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In a smaller place like Uxbridge, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Uxbridge buildings and the weather
With historic houses such as Ickenham Hall (about 2.2 miles north-east) nearby, there’s older building stock in the area around Uxbridge as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of 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 West Drayton station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Whitehall Junior School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Concrete & block
- Copings & trims
- Brickwork movement joints
What we’re called out for in Uxbridge
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Signs it’s time to call us include:
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
For an older house near a landmark such as Church of St Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a handful of joints, longer for a whole elevation. A visit to Uxbridge is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Make sure movement joints are not pointed over
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
