- Gaps where render, brick and frames meet
How we handle external mastic in Westfield
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. If you’re dealing with weathered mastic that no longer stretches and rigid filler in a joint that should flex, we can help, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Westfield add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Walls and rooflines in Westfield
With historic houses such as Clandon Park (about 4.1 miles south-east) nearby, there’s older building stock in the area around Westfield as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Homes close to St Mark's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Westfield Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What we’re called out for in Westfield
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
Common reasons people contact us include:
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
Letting a property close to Woking station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
- How long to leave it before use
- Is VAT in the price?
When something else is needed
In fairness, some problems need a different trade:
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
- Movement that’s more than a sealant joint can take
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Why act early in Westfield
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a smaller place like Westfield, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the building. For a job in Westfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Tell us about any water getting in

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.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
