How external mastic works in Windsor and Maidenhead
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, render & cladding joints and façade panels, and people most often call us about joints where the bead has come unstuck and brick movement joints where the sealant has split.
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes anything from a few hours to several days, depending on the building.
- 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.
- We apply the sealant, tool it and check the whole run.

Walls and rooflines across Windsor and Maidenhead
Our external mastic work across Windsor and Maidenhead covers homes, blocks and business premises, from Maidenhead, Windsor and Boyn Hill to the quieter places in between. Outside joints can only be sealed when they’re dry, so the work is planned around the weather.
London and the South East have homes from every era, from period terraces to post-war new towns and new estates. Each needs the right sealant for its age and materials.
Maidenhead: For an older house near a landmark such as All Saints' Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Maidenhead station, split movement joints are easy to miss on a rental until damp shows inside.
When something else is needed
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- When we can work, for business premises
- Which sealant suits the joint
- Any mould that needs treating
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
- Have failed joints looked at early
- Don’t let climbing plants root in the sealant
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself.

Questions from Windsor and Maidenhead
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before we start from the range available.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
