External & façade joints in Brook Street, West Sussex
Our applicators work in Brook Street on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
How we handle external mastic in Brook Street
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have joints where the bead has come unstuck and weathered mastic that no longer stretches, we can help.
Somewhere as small as Brook Street, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Outside joints around Brook Street
With historic houses such as Ockenden Manor (about 1.3 miles south) nearby, there’s older building stock in the area around Brook Street as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Haywards Heath station, split movement joints are easy to miss on a rental until damp shows inside. Historic houses such as Ockenden Manor, about 1.3 miles south, show how far back building around Brook Street goes.

Brook Street questions
I let a flat near Haywards Heath station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can you do external mastic in Brook Street?
Yes. We work across London and the South East, and Brook Street is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
How long before the joint can be used?
It depends on the product. Before we leave, we’ll tell you the cure time.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Signs you need external mastic in Brook Street
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
These are the problems we are asked about most:
- Failed seals between different materials
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
Schools such as Holy Trinity Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- Are they insured?
- What product goes in the joint
- How much experience the applicator has
- Whether all the old sealant comes out first
How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the building in most cases. For a village or hamlet like Brook Street, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Related advice
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we cannot put right
A few problems are outside what sealant work can do:
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Why act early in Brook Street
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Brook Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits. We’ll give you a clear price for the lot.
