About our external mastic in Beacon Hill
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. Typical jobs include sealant pulling away from one side of the joint and old sealant gone brittle and cracked, on copings & trims, render & cladding joints and joints between brick and frames.
Somewhere as small as Beacon Hill, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that is more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on

Do you need external mastic in Beacon Hill?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Any of these means the joints need attention:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
Rented homes near Haslemere station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. In a small place like Beacon Hill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

Very little: the area around the joints is protected first, and we tidy up before we go.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.

What external mastic looks like in Beacon Hill
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.
Managing a site like Beacon Hill Community Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Alban, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Act on the first splits you see
- Never let anyone fill a movement joint with mortar
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
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.
