What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Should I try DIY first?
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.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch. If it has already been filled, we can usually cut it out and reseal it.

External mastic for homes and businesses in Wargrave
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, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are panel joints letting water in and joints with sealant missing in places.
In and around Wargrave, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
A one-year guarantee comes as standard.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. In a smaller place like Wargrave, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Looking after it afterwards
After the cure time, these simple habits help:
- Check external joints each spring
- Leave the joints unpainted unless we have said otherwise
- Point out the joints to other trades
- Have failed joints looked at early
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

Why it’s worth doing now in Wargrave
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Wargrave, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Rising or penetrating damp from elsewhere in the wall
- Movement that is more than a sealant joint can take
- Render that’s blown, hollow or coming away
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Walls and rooflines in Wargrave
With historic houses such as Harleyford Manor (about 4.2 miles north-east) nearby, there’s older building stock in the area around Wargrave as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Robert Piggott CofE Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Wargrave station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
