What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around West Hagbourne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

External mastic in West Hagbourne, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on brickwork movement joints, façade panels and render & cladding joints, and the jobs we see most are sealant that has lost its bond to the brick or render and gaps where render, brick and frames meet.
External sealant needs dry, clean surfaces, so work around West Hagbourne is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, whatever its size.

For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Aftercare tips
A little care helps the new joints last. Our advice:
- Ask before painting over external sealant
- Keep water from gutters off the wall
- Point out the joints to other trades
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
What happens on the day
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Somewhere like West Hagbourne needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Move anything stored near the joints
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Render & cladding joints
Other services in West Hagbourne
What we’re called out for in West Hagbourne
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
The problems people usually mention when they call are:
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
For an older house near a landmark such as Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in West Hagbourne: local notes
With historic houses such as Brightwell Manor (about 4.5 miles north-east) nearby, there’s older building stock in the area around West Hagbourne as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Didcot Parkway station? Then split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Hagbourne Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Are you insured?
Yes. Full insurance covers our work.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Surface by surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
