About our external mastic in Waterhall
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. We work on copings & trims, façade panels and render & cladding joints, and people most often call us about weathered mastic that no longer stretches and moss and dirt in joints with no sealant left.
In a village or hamlet like Waterhall, older cottages and farm buildings often stand in the open, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
What we are called out for in Waterhall
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
People generally contact us after spotting one of these:
- Water getting into walls through failed joints
- Hard, crazed mastic that has stopped moving
- Joints with sealant missing in places
- Panel joints letting water in
If you live in an older home near All Saints Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- Which sealant they’ll use, and why
- Whether VAT is included
- Which colour the sealant will be
- How long the guarantee is
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Waterhall can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Why us?
- You choose the colour before work begins
- A sealant colour to suit the surroundings
- A 12-month guarantee on all work
- More than 20 years in sealant work

FAQs for Waterhall
Is Waterhall within the area you cover?
Yes, Waterhall is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Preston Park station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Where do you work from?
We work from Crawley. We cover Waterhall and the rest of Brighton and Hove, along with the rest of our area.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Work for landlords, hotels and businesses
Landlords and agents in Waterhall can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
A little care helps the new joints last. We recommend:
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
The process
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as Waterhall, access is often the only tricky part. 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.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
How to get a quote

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Waterhall buildings and the weather
Waterhall 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Preston Park station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Westdene Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
