How we handle external mastic in Arborfield
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 façade panels, render & cladding joints and concrete & block, and common reasons people get in touch are movement joints filled with mortar instead of sealant and joints with sealant missing in places.
Older homes in small places like Arborfield may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What external mastic looks like in Arborfield
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Winnersh station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as The Coombes Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:
- The number and length of the joints
- Any mould that needs treating
- How easy the joints are to reach
- The type of sealant required
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Do you need external mastic in Arborfield?
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Most people get in touch when they notice something like this:
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Bartholomew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the building. In a small place like Arborfield, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Point out the joints to other trades
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint cannot move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way. Around Arborfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
