About our external mastic in Satmar
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 a rigid filler would soon crack. Common call-outs are for sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet, across render & cladding joints, copings & trims and façade panels.
External sealant needs dry, clean surfaces, so work around Satmar is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Landlord and commercial work in Satmar
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
What sealant work can’t fix
It helps to know what we can’t do:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels

Common questions in Satmar
Will you come out to Satmar?
Yes, Satmar 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.
Does living near the coast affect external mastic in Satmar?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How do I get a quote for external mastic in Satmar?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
When to call us in Satmar
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Keep an eye out for any of the following:
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Brick movement joints where the sealant has split
For landlords with property near Folkestone Central station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Access and height
- Whether there’s mould to deal with
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
If you’re in Satmar and need external mastic, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. In a small place like Satmar, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Let us know about parking restrictions
How to get a quote

Why it’s worth doing now in Satmar
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In a small place like Satmar, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Anti-fungal silicone where joints get wet
- Old sealant always removed completely
- You choose the colour before work begins
- A sealant colour to suit the surroundings

Walls and rooflines in Satmar
Satmar is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
For an older house near a landmark such as St Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Capel-le-Ferne Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
