About our external mastic in Hacklinge
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with failed sealant between panels on a façade and joints with sealant missing in places, we can put it right, whatever the surface.
Older homes in small places like Hacklinge may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You get a one-year guarantee, the same in Hacklinge as everywhere else we work.

What external mastic looks like in Hacklinge
Hacklinge is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Walmer Castle (about 3.5 miles south-east) are a reminder that the area around Hacklinge has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Worth Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Sandwich station, split movement joints are easy to miss on a rental until damp shows inside.
Hacklinge is about 2 miles north-west of Deal, in Kent. Jobs in Hacklinge get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.

Why act early in Hacklinge
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Older cottages and farmhouses around Hacklinge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Why Hacklinge clients choose us
- Old sealant always removed completely
- 12-month guarantee on every job

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Somewhere like Hacklinge 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.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Your questions about external mastic in Hacklinge
Will you come out to Hacklinge?
Yes. Hacklinge is within the area we cover, which takes in towns, villages and rural addresses. 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 a coastal place like Hacklinge any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When to call us in Hacklinge
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Joints pointed up with cement by mistake
- Old sealant gone brittle and cracked
If you live in an older home near Church of St George, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- How the joint is cleaned and prepared
- How hidden problems are handled
- What insurance they hold
- How long the guarantee is
