External mastic for homes and businesses in Goodworth Clatford
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have hard, crazed mastic that has stopped moving and plants rooting in failed movement joints, we can help, on façade panels, render & cladding joints and brickwork movement joints alike.
Outside joints can only be sealed when they’re dry, so work in Goodworth Clatford is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Common questions in Goodworth Clatford
Will you come out to Goodworth Clatford?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Goodworth Clatford in your area for external mastic?
Yes, Goodworth Clatford is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Are you insured?
Yes. We are fully insured.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere like Goodworth Clatford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Landlord and commercial work in Goodworth Clatford
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check external joints each spring
- Tell anyone working on the walls about the movement joints
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Outside joints around Goodworth Clatford
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Andover station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Clatford Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What we are called out for in Goodworth Clatford
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Look out for these signs:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
If you live in an older home near Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.
