How it works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the building. For a village or hamlet like Hillstreet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

About our external mastic in Hillstreet
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. If you have brick movement joints where the sealant has split and rigid filler in a joint that should flex, we can put it right.
Older homes in small places like Hillstreet may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why act early in Hillstreet
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Hillstreet can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

What we are called out for in Hillstreet
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
Rented homes near Totton station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Make sure movement joints are not pointed over
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

Hillstreet buildings and the weather
Hillstreet is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Calmore Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Anne's, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions from Hillstreet
Is Hillstreet within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is external mastic in a coastal place like Hillstreet any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
Where do you work from?
We work from Crawley. Our applicators cover Hillstreet.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
What is backing rod for?
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.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
