Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we handle external mastic in Findon Valley
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have hard, crazed mastic that has stopped moving and failed sealant between panels on a façade, we can help, on concrete & block, joints between brick and frames and façade panels alike.
In a smaller place like Findon Valley, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Looking after it afterwards
Aftercare is simple:
- Act on the first splits you see
- Show decorators and builders where the movement joints are
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Findon Valley: your questions answered
Do you work for landlords with property near West Worthing station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do external mastic in Findon Valley?
Yes, Findon Valley is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
How long will you be here?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including the preparation. We will confirm how long when we quote.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a smaller place like Findon Valley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint

Walls and rooflines in Findon Valley
With historic houses such as Ecclesden Manor (about 3.5 miles south-west) nearby, there’s older building stock in the area around Findon Valley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Vale School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near West Worthing station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Advice
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.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
