How we handle external mastic in Perry
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on façade panels, concrete & block and copings & trims, and people most often call us about panel joints letting water in and joints with sealant missing in places.
Somewhere as small as Perry, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Every job comes with our one-year guarantee.

Landlord and commercial work in Perry
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
How to look after the new joints
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. In a small place like Perry, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Perry: your questions answered
Will you come out to Perry?
Yes, Perry is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Adisham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
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 one-year guarantee.
Outside joints around Perry
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Goodnestone Park (about 3.1 miles south) are a reminder that the area around Perry has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Preston Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Adisham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need external mastic in Perry?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Any of these means the joints need attention:
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Movement joints filled with mortar instead of sealant
For an older house near a landmark such as Elmstone Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Perry, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

What sealant work can’t fix
It helps to know what we cannot do:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
