How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere as small as Ibworth, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

FAQs for Ibworth
Do you cover smaller places like Ibworth?
Yes, Ibworth is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Overton station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before any work starts from the range available.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:

- Movement that’s more than a sealant joint can take
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

We quote each job individually. These are the things that affect it:
- Working hours on commercial sites

- Mould in or behind the old joints

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote

How the job changes by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Send us any details you have about the façade.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Outside joints around Ibworth
Historic houses like The Vyne (about 4.8 miles north-east) are a reminder that the area around Ibworth 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Overton station, split movement joints are easy to miss on a rental until damp shows inside. The Vyne, about 4.8 miles north-east, is one of the historic houses in the wider area around Ibworth.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted and spoil the finish.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Ibworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
