Slough External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Slough. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
Honest limits
In fairness, there are a few things sealant will not fix:
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
- Render that is blown, hollow or coming away

External mastic for homes and businesses in Slough
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on render & cladding joints, brickwork movement joints and copings & trims, and people most often call us about damp patches traced to an open external joint and gaps where render, brick and frames meet.
Larger buildings in Slough have plenty of movement joints, cladding joints and roofline trims. A failed joint lets water behind the brick or render, where it often goes unnoticed for a while.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Slough questions
Is there a guarantee on external mastic in Slough?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Slough station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so it doesn’t stand out.
Do you come to Slough?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Slough.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
How we quote for external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- Whether there’s mould to deal with
- Whether the work is at height
- How much there is to do
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- Where the property is
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
Walls and rooflines in Slough
With historic houses such as Windsor Castle (about 2.1 miles south) nearby, there’s older building stock in the area around Slough 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Michael and All Angels, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Slough station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why act early in Slough
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Busy buildings in Slough, from hotels to offices, can’t afford rooms out of use for leaks or mould, so failing joints are best replaced on a planned basis.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why us?
- Domestic, commercial and hotel work
- White, clear, grey or coloured to suit, where the product allows

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we’ve said otherwise
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Where a business in Slough needs to stay open, out-of-hours working can be arranged, while home visits are arranged within our normal working hours, Monday to Saturday.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

When to call us in Slough
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
The problems people usually mention when they call are:
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
If you look after a building such as Herschel Grammar School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- Is the old sealant removed completely?
- When the joint can take water or movement
- How the joint is cleaned and prepared
- The length of the guarantee
