About our external mastic in Brook Street
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint doesn’t stand out. If you’re dealing with water getting into walls through failed joints and old sealant gone brittle and cracked, we can help.
Outside joints can only be sealed when they’re dry, so work in Brook Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job.

When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before we start. Sealant will not put right:
- Cracking across the wall rather than at a joint
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Signs you need external mastic in Brook Street
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for these signs:
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
Rented homes near Brentwood station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- How much experience the applicator has
- What the quote includes, VAT included or not
- How long the guarantee is
- What product goes in the joint
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.

Outside joints around Brook Street
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hare Hall (about 3.2 miles south-west) are a reminder that the area around Brook Street 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.
For an older house near a landmark such as Church of St Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Holly Trees Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Is Brook Street within the area you cover?
Yes. Brook Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
How to look after the new joints
After the cure time, these simple habits help:
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Work for landlords, hotels and businesses
If you manage several properties in or around Brook Street, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Landlords and letting agents in Brook Street can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In a small place like Brook Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- Mention any parking rules near the property
