What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. In Hampton, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Advice
External mastic for homes and businesses in Hampton
On houses, flats and commercial buildings across Hampton, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for plants rooting in failed movement joints and movement joints with cracked, split or missing sealant, on façade panels, brickwork movement joints and joints between brick and frames.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Hampton, it’s worth checking who is responsible for the outside before booking.
There’s a 12-month guarantee on every job.

Why it’s worth doing now in Hampton
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a flat in Hampton, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Hampton buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. With historic houses such as Strawberry Hill House (about 2 miles north-east) nearby, there’s older building stock in the area around Hampton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Hampton station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Hampton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Quotes for external mastic in Hampton
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- The type of sealant required
- The size of the job
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Helping us quote
To make quoting easier, please include:
- The address or postcode of the job
- Photos by email, if that’s easy
- The type of property
- Whether it has been sealed before
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
What we are called out for in Hampton
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint.
Look out for these signs:
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
For an older house near a landmark such as All Saints' Hampton, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- What guarantee comes with the work
- Which sealant they’ll use, and why
- Who turns up on the day
- Which colour the sealant will be
Keeping the joints in good condition
Aftercare is simple:
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
- Act on the first splits you see
- Keep water from gutters off the wall
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
When something else is needed
In fairness, some problems need a different trade:
- Subsidence or other structural problems
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
What we seal
- Concrete & block
- Render & cladding joints

Common questions in Hampton
Can you help a landlord with a rental near Hampton station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Hampton for external mastic?
Yes. We work across London and the South East, and Hampton is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How long does external mastic take?
Typically it takes anything from a few hours to several days, depending on the building. Larger jobs naturally take longer.
