External mastic for homes and businesses in Leckford
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We work on copings & trims, joints between brick and frames and render & cladding joints, and the jobs we see most are panel joints letting water in and cracked joints where brick meets render or frames.
External sealant needs dry, clean surfaces, so work around Leckford is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

Questions from Leckford
Do you cover Leckford for external mastic?
Yes, Leckford is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Will you come out to Leckford?
Yes, Leckford is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How do I get a quote for external mastic in Leckford?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long does external mastic take?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. Your quote will say how long we expect yours to take.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin.
What we’re called out for in Leckford
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
The problems people normally mention when they call include:
- Moss and dirt in joints with no sealant left
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
Managing a site like Test Valley School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
What the job involves on each surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Walls and rooflines in Leckford
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Nicholas, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, 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.
When something else is needed
We will always be straight with you, so here’s what sealant can’t fix:
- Structural movement, which needs a surveyor or engineer
- Render that is blown, hollow or coming away
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Leckford, the journey is planned in advance: 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
