External mastic for homes and businesses in Pease Pottage
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and render & cladding joints, and the jobs we see most are weathered mastic that no longer stretches and sealant pulling away from one side of the joint.
In and around Pease Pottage, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a smaller place like Pease Pottage, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Pease Pottage buildings and the weather
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. Pease Pottage is part of Crawley, one of the post-war new towns. Many homes date from the post-war decades and were built in phases, so whole streets can have gutters, trims and wall joints reaching the end of their life together.
Tyes Place, about 3.4 miles south, is one of the historic houses in the wider area around Pease Pottage, and older homes nearby need a sealant that suits their walls. Letting a property close to Crawley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Pease Pottage questions
Should the sealant in an older Pease Pottage home be renewed?
If it hasn’t been replaced for some years, it’s generally worth it. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in Pease Pottage may already be on their second or third set.
Will you come out to Pease Pottage?
Yes, Pease Pottage is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
How long does external mastic take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will say how long yours will take.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
How the job changes by surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.

What else we do in Pease Pottage
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
When to call us in Pease Pottage
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
People usually contact us after spotting something like this:
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
For site and facilities teams at buildings such as Discovery New School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Whether the sealant suits the joint
- Are they insured?
- How long to leave it before use
- What preparation is included
How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Pease Pottage, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
