What affects the cost of external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
When you call or email, it’s useful to know:
- A few photos by email, if you can
- Any previous sealing or DIY work
- Where the property is
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
About our external mastic in Stonebridge Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. Typical jobs include joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving, on render & cladding joints, joints between brick and frames and façade panels.
In a village or hamlet like Stonebridge Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. For a village or hamlet like Stonebridge Green, the journey is planned in advance: 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.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

Why act early in Stonebridge Green
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Older cottages and farmhouses around Stonebridge Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- Experience in homes, commercial sites and hotels
- Tidy, careful work
- Trusted Arbo and Everbuild sealants
- White, clear, grey or coloured to suit, where the product allows

Signs you need external mastic in Stonebridge Green
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
These are the problems we’re asked about most:
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
If you live in an older home near Church of St James, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
- Keep soil, plants and ivy away from the joints
- Fix overflowing gutters above sealed joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Walls and rooflines in Stonebridge Green
With historic houses such as Godinton House (about 5 miles south-east) nearby, there’s older building stock in the area around Stonebridge Green 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. 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.
Schools such as Egerton Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Charing station? Then split movement joints are easy to miss on a rental until damp shows inside.

What the job involves on each surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
