Why it’s worth doing now in Little Hadham
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Little Hadham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Outside joints around Little Hadham
Historic houses like Much Hadham Palace (about 2 miles south) are a reminder that the area around Little Hadham 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 Little Hadham Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Homes close to Parish Church of St Cecilia include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Deal with leaking gutters that soak the joints below
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Signs you need external mastic in Little Hadham
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
These are the problems we’re asked about most:
- Gaps where render, brick and frames meet
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
If you let a flat or house near Bishops Stortford station, split movement joints are easy to miss on a rental until damp shows inside.

FAQs for Little Hadham
Is Little Hadham within the area you cover?
Yes, Little Hadham is covered. 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.
I let a flat near Bishops Stortford station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear 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.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
How long does external mastic take?
That depends on the amount of work, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any working-time requirements on site
- Access and height
- The old material and how stubborn it is
- Mould in or behind the old joints
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Little Hadham needs a little journey planning: let us know about lanes, gates and parking. 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.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- 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
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
