How we handle external mastic in Yateley
On houses, flats and commercial buildings across Yateley, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We are often asked to deal with water getting into walls through failed joints and joints pointed up with cement by mistake, across joints between brick and frames, façade panels and brickwork movement joints.
Yateley mixes older houses and their gutters with newer estates of brick, render and uPVC trims. Gutter joints, fascia trims and the movement joints in newer brickwork all need sealant that can flex.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Parking in a town like Yateley is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Yateley questions
Is there a guarantee on external mastic in Yateley?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Yateley for external mastic?
Yes. We work across London and the South East, and Yateley is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Walls and rooflines in Yateley
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.
If you live in an older home near Church of St Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Yateley School? Then larger buildings have long runs of movement joint that eventually need resealing.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep water from gutters off the wall
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
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.
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 which cost more to put right than the joint.
Do you need external mastic in Yateley?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Keep an eye out for these signs:
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
If you let a flat or house near Sandhurst station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- How long to leave it before use
- What insurance they hold
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Yateley, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
