How we handle external mastic in Hadham Ford
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We are often asked to deal with old sealant gone brittle and cracked and sealant pulling away from one side of the joint, across render & cladding joints, copings & trims and façade panels.
Somewhere as small as Hadham Ford, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a 12-month guarantee.

Common problems we fix in Hadham Ford
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
People usually contact us after spotting one of these:
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
Letting a property close to Bishops Stortford station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether all the old sealant comes out first
- What insurance they hold
- How the surfaces are prepared before sealing
- Whether you can choose the colour
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Any mould that needs treating
- How easy the joints are to reach
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- Pictures of the joints, sent by email
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Somewhere like Hadham Ford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip 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.
- 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.
Getting ready for the visit

Why it’s worth doing now in Hadham Ford
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a small place like Hadham Ford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

Hadham Ford questions
Can you help a landlord with a rental near Bishops Stortford station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover Hadham Ford for external mastic?
Yes, Hadham Ford is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Outside joints around Hadham Ford
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Much Hadham Palace (about 1.4 miles south) nearby, there’s older building stock in the area around Hadham Ford 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 Parish Church of St Cecilia include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Little Hadham Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How to look after the new joints
Aftercare is simple:
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
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 we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Brickwork movement joints
- Façade panels
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
