External Mastic in Nork
Professional external mastic in and around Nork, with old sealant always removed completely and a 12-month guarantee.
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
How we handle external mastic in Nork
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We’re often asked to deal with joints where the bead has come unstuck and cracked joints where brick meets render or frames, across render & cladding joints, joints between brick and frames and brickwork movement joints.
Houses in smaller places like Nork can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
All our work is covered by a one-year guarantee.

What we are called out for in Nork
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
Managing a site like Warren Mead Infant School? Then its movement joints, gutters and trims need looking after like any other building’s.
Before you book anyone
- Are they insured?
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
Why act early in Nork
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Homes in smaller places like Nork can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Your questions about external mastic in Nork
I let a flat near Banstead station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Nork?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Where do you work from?
Mr Mastic is based in Crawley. We cover Nork and the rest of Surrey.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.

External mastic in Nork: local notes
With historic houses such as Fitznells Manor (about 2.4 miles north-west) nearby, there’s older building stock in the area around Nork as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Banstead station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on how much there is to do. For a job in Nork, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Different surfaces, different methods
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
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.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
