About our external mastic in Hickmans Green
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you’re dealing with cracked joints where brick meets render or frames and sealant that has lost its bond to the brick or render, we can help, on joints between brick and frames, brickwork movement joints and façade panels alike.
Older homes in small places like Hickmans Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. For a village or hamlet like Hickmans Green, the journey is planned in advance: 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear quote for the lot.

Walls and rooflines in Hickmans Green
Historic houses like Belmont House and Gardens (about 4.9 miles west) are a reminder that the area around Hickmans Green has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Selling station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why deal with it now?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Where a wall is exposed, as many are in small places like Hickmans Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Do you need external mastic in Hickmans Green?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Keep an eye out for these signs:
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
In the older streets around St Barnabas, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- How hidden problems are handled
- Are they insured?
- How the colour is chosen
- Is the old sealant removed completely?

What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Movement that’s more than a sealant joint can take
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
