Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
About our external mastic in Goldsworth Park
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 colour to suit. We work on concrete & block, joints between brick and frames and brickwork movement joints, and people most often call us about water getting into walls through failed joints and brick movement joints where the sealant has split.
In a smaller place like Goldsworth Park, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
A 12-month guarantee comes as standard.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them

Why act early in Goldsworth Park
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a smaller place like Goldsworth Park, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Goldsworth Park buildings and the weather
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. With historic houses such as Botleys Mansion (about 4.4 miles north-east) nearby, there’s older building stock in the area around Goldsworth Park as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of St Andrew include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Goldsworth Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Woking station? Then split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Goldsworth Park
Do you cover smaller places like Goldsworth Park?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Goldsworth Park for external mastic?
Yes, Goldsworth Park is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
What is a movement joint?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.
Where do you work from?
Mr Mastic is based in Crawley. We cover Goldsworth Park and the rest of Surrey.
What we do, step by step
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Parking around Goldsworth Park is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Advice
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep soil, plants and ivy away from the joints
- Keep high-pressure jets off the joints
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we’ve said otherwise
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
