External & façade joints in Park Wood, Medway
Specialist external mastic for Park Wood: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Weeds or debris growing in open joints
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
External mastic for homes and businesses in Park Wood
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you have weeds or debris growing in open joints and damp patches traced to an open external joint, we can put it right.
Outbuildings, garages and conservatories around homes in places like Park Wood add more joints to look after. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
Every job is covered by our 12-month guarantee, wherever you are in Medway.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Parking around Park Wood is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Mention any tricky access

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. 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.
How to look after the new joints
So the new joints stay in good condition:
- Have failed joints looked at early
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we have said otherwise
- Keep soil, plants and ivy away from the joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Park Wood: your questions answered
Is Park Wood in your area for external mastic?
Yes, Park Wood is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Is Park Wood within the area you cover?
Yes, Park Wood is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
How much does external mastic cost in Park Wood?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Park Wood, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Walls and rooflines in Park Wood
Historic houses like Restoration House (about 4.9 miles north-west) are a reminder that the area around Park Wood has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
In the older streets around St Paul's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Park Wood Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Rainham (Kent) station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
