External Mastic in Brick Hill
We cover Brick Hill for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Joints pointed up with cement by mistake
- Panel joints letting water in
- Gaps where render, brick and frames meet
About our external mastic in Brick Hill
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on joints between brick and frames, brickwork movement joints and copings & trims, and people most often call us about brick movement joints where the sealant has split and hard, crazed mastic that has stopped moving.
Around Brick Hill, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
Our work is backed for twelve months.

What we are called out for in Brick Hill
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
Homes close to Church of St Saviour include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Brick Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.

Brick Hill buildings and the weather
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. Historic houses like Botleys Mansion (about 4 miles east) are a reminder that the area around Brick Hill 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 Sunningdale station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Valley End CofE Infant School? Then larger buildings have long runs of movement joint that eventually need resealing.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Avoid pressure-washing directly into sealant joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
How we quote for external mastic
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- Working hours on commercial sites
- The number and length of the joints
- The type of sealant required
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Helping us quote
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- Roughly how big the job is
- Pictures of the joints, sent by email
- How we’d reach the joints
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Common questions in Brick Hill
Do you cover Brick Hill for external mastic?
Yes, Brick Hill is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Will you come out to Brick Hill?
Yes, Brick Hill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
How long does the job take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we will say how long yours will take.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
