External & façade joints in Kimpton, Hampshire
Movement joints in Kimpton need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

When to call us in Kimpton
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Common reasons people contact us include:
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
If you let a flat or house near Grateley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic in Kimpton, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. If you have water getting into walls through failed joints and weathered mastic that no longer stretches, we can help, whatever the surface.
In a village or hamlet like Kimpton, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a 12-month guarantee.

Why it’s worth doing now in Kimpton
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Kimpton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Anti-fungal silicone where joints get wet
- Neat joints and a tidy finish
- White, clear, grey or another colour, product permitting
- An ARBOMaster approved applicator

What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.

How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere like Kimpton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

External mastic in Kimpton: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Kimpton is about 5 miles west of Andover, in Hampshire. Wherever you are in the SP11 postcode area, we can carry out external mastic at your property. Kimpton is one of 683 places in Hampshire we cover. Our Southampton page covers work nearby.
Work in SP11 works the same way as everywhere else we cover. Whether your property is on Cow Lane, Deacon Road and Down Road or a nearby road, our applicators can take on the job. Neighbouring places we cover for external mastic include Great Shoddesden (1 mile north), Perham Down (2 miles north-west), Ludgershall (2 miles north-west), Tidworth (3 miles west) and Shipton Bellinger (3 miles west).

Near you in Kimpton
Kimpton’s nearest station is Grateley station, about 3.9 miles south. Other landmarks nearby include Ludgershall Castle (2.6 miles north-west) and Andover War Memorial Hospital (4.6 miles east). The countryside around Kimpton includes Anton Lakes and Quarley Hill.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

What sealant work can’t fix
It helps to know what we can’t do:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Questions from Kimpton
I let a flat near Grateley station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Kimpton?
Yes. Kimpton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
