Nutcombe External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Nutcombe and across Surrey. Fully insured, ARBOMaster approved and guaranteed for a year.
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
External mastic in Nutcombe
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we don’t skip that step. We work on brickwork movement joints, copings & trims and render & cladding joints, and the jobs we see most are water getting into walls through failed joints and sealant that has lost its bond to the brick or render.
Somewhere as small as Nutcombe, 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 there’s a problem with it, please call 0345 464 0079 or drop us an email.

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Nutcombe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Related advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
- Point out the joints to other trades
- Don’t let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- How much there is to do

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Walls and rooflines in Nutcombe
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Haslemere station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of St Luke, an extension built onto an older house moves differently, and the joint between them takes the strain.

Nutcombe: your questions answered

Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Are you fully insured?
Yes. We’re fully insured.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Common problems we fix in Nutcombe
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
People normally contact us when they notice one of these:
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
If you look after a building such as Amesbury School, larger buildings have long runs of movement joint that eventually need resealing.
