What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
External mastic in Hatchet Green
On houses, flats and commercial buildings across Hatchet Green, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on brickwork movement joints, render & cladding joints and joints between brick and frames, and the jobs we see most are moss and dirt in joints with no sealant left and failed sealant between panels on a façade.
In a village or hamlet like Hatchet Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about external mastic in Hatchet Green
Do you cover smaller places like Hatchet Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is external mastic in Hatchet Green guaranteed?
All our work, in Hatchet Green and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Quotes for external mastic in Hatchet Green
There’s no set price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- Which sealant suits the joint
- Any working-time requirements on site
- Access and height
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- A few pictures by email, if you can
- Where the property is
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Show decorators and builders where the movement joints are
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
External mastic in Hatchet Green: local notes
With historic houses such as Breamore House (about 2.6 miles west) nearby, there’s older building stock in the area around Hatchet Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Somewhere like Hatchet Green 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 inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
When it is not the sealant
We won’t take on work that will not last, so these are the limits:
- Render that’s blown, hollow or coming away
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Façade panels
Signs you need external mastic in Hatchet Green
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 tears as soon as the joint widens.
Common reasons people contact us include:
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
- Panel joints letting water in
Schools such as Hale Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- Who turns up on the day
- Whether they seal over old material or remove it
- The length of the guarantee
- Whether the sealant suits the joint
