About our external mastic in Woodside
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We are often asked to deal with rigid filler in a joint that should flex and brick movement joints where the sealant has split, across joints between brick and frames, render & cladding joints and façade panels.
Around Woodside, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Outside joints around Woodside
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.
If you look after a building such as Vernham Dean Gillum's Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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 does not work out, we can still put it right.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Woodside, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Clear the area around the work

Advice
When to call us in Woodside
Sunlight, wet weather and frost wear exterior sealant down. 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.
The problems people generally mention when they call are:
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Sealant pulling away from one side of the joint
If you live in an older home near Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure movement joints aren’t pointed over
- Point out the joints to other trades
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Woodside, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
