Specialist external mastic for Mogador: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
Common problems we fix in Mogador
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Failed seals between different materials
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
If you look after a building such as Kingswood Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- Are they insured?
- Which sealant they’ll use, and why
- Which colour the sealant will be
- How long to leave it before use
External mastic for homes and businesses in Mogador
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on façade panels, render & cladding joints and copings & trims, and common reasons people get in touch are rain getting behind render or cladding at a joint and joints pointed up with cement by mistake.
Older homes in small places like Mogador may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
There’s a 12-month guarantee on every job, whatever its size.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- How many areas need sealing
- The type of sealant required
- How much old sealant there is and how hard it is to remove
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
To help us quote quickly, let us know:
- Whether it has been sealed before

- The problem you’ve noticed
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.
Walls and rooflines in Mogador
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Reigate station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of Jesus Christ and the Wisdom of God, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal

What happens on the day
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Mogador needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Advice
Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Why it’s worth doing now in Mogador
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Where a wall is exposed, as many are in small places like Mogador, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Mogador: your questions answered
Do you cover smaller places like Mogador?
Yes. Mogador is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Mogador for external mastic?
Yes. We work across London and the South East, and Mogador is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
Where are you based?
We work from Crawley. Our applicators cover Mogador, along with the rest of our area.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.
