About our external mastic in Domewood
Low-level joints can normally 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, concrete & block and joints between brick and frames, and people most often call us about old sealant gone brittle and cracked and rain getting behind render or cladding at a joint.
Outside joints can only be sealed when they’re dry, so work in Domewood is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Every job is covered by a 12-month guarantee, wherever you are in West Sussex.

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Domewood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Your questions about external mastic in Domewood
Do you work for landlords with property near East Grinstead station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Do you cover Domewood for external mastic?
Yes, Domewood is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
When to call us in Domewood
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Joints pointed up with cement by mistake
Managing a site like Imberhorne School? Then its movement joints, gutters and trims need looking after like any other building’s.
Before booking anyone
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Whether VAT is included
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Avoid pressure-washing directly into sealant joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
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 early resealing is worth it.
Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Outside joints around Domewood
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. Historic houses like Saint Hill Manor (about 3.5 miles south-east) are a reminder that the area around Domewood has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to East Grinstead station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Saint Hill Manor, about 3.5 miles south-east, is one of the historic houses in the wider area around Domewood, and older homes nearby need a sealant that suits their walls.

What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. For a village or hamlet like Domewood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
