Hampton: your questions answered
Is external mastic in a coastal place like Hampton any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Hampton?
Yes, Hampton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
External mastic for homes and businesses in Hampton
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. We work on copings & trims, render & cladding joints and concrete & block, and people most often call us about weathered mastic that no longer stretches and damp patches traced to an open external joint.
In and around Hampton, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
You get a one-year guarantee, the same in Hampton as everywhere else we work.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Avoid pressure-washing directly into sealant joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
What external mastic looks like in Hampton
Hampton is within about 1 mile 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Herne Bay station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around St Andrew's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Hampton Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
Hampton is about 2 miles west of Herne Bay, in Kent. We provide external mastic to householders, landlords and businesses in Hampton and nearby, as part of our work across Kent. 922 places in Kent are on our list. Chelmsford is on our list too, about 37 miles from Hampton.
We cover every part of CT6 for external mastic and the streets around it. Local streets include Riley Avenue, Essex Avenue and Alvis Avenue, and we cover them all. If you are just outside Hampton, we cover Swalecliffe (2 miles south-west), West End (2 miles south), Chestfield (2 miles south-west), Tankerton (2 miles west) and Radfall (3 miles south-west). Within a short drive, we also cover Canterbury (6 miles south), Margate (12 miles east), Ramsgate (14 miles east), Broadstairs (14 miles east), Faversham (10 miles south-west) and Minster (13 miles west).
Around Hampton

How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Why act early in Hampton
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Around Hampton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What happens on the day
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a job in Hampton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
