External Mastic in Sulhamstead
Our applicators work in Sulhamstead on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
External mastic in Sulhamstead
For buildings in Sulhamstead, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on joints between brick and frames, concrete & block and brickwork movement joints, and common reasons people get in touch are gaps where render, brick and frames meet and joints with sealant missing in places.
Somewhere as small as Sulhamstead, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it is not the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
- Render that is blown, hollow or coming away
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What affects the cost of external mastic
You’ll get a clear quote before any work starts. It takes into account:
- The number of rooms or windows
- The size of the job
- The product the joint needs
- Access and height
Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.
Helping us quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
Every job is quoted individually. Just phone 0345 464 0079 or email us with the details, and photos are welcome.
When to call us in Sulhamstead
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
Schools such as Sulhamstead and Ufton Nervet School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- What happens if the job turns out different
- How long the guarantee is
- What the cure time is
- What product goes in the joint
Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
External mastic in Sulhamstead: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Theale station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Your questions about external mastic in Sulhamstead
Will you come out to Sulhamstead?
Yes. Sulhamstead is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Theale station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How much does external mastic cost in Sulhamstead?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
The process
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Sulhamstead, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Why it’s worth doing now in Sulhamstead
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Older cottages and farmhouses around Sulhamstead can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
