About our external mastic in Spring Vale
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We work on brickwork movement joints, façade panels and concrete & block, and people most often call us about water getting into walls through failed joints and sealant pulling away from one side of the joint.
Around Spring Vale, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Each job carries a 12-month guarantee, whatever its size.

Different surfaces, different methods
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as Spring Vale, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any parking rules near the property
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
Landlord and commercial work in Spring Vale
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
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.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How to look after the new joints
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Keep high-pressure jets off the joints
- Check external joints each spring
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Spring Vale: your questions answered
Does living near the coast affect external mastic in Spring Vale?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Spring Vale?
Yes, Spring Vale is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

What external mastic looks like in Spring Vale
Spring Vale is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Nunwell House (about 3.2 miles south-west) are a reminder that the area around Spring Vale has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near St. Peter's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Nettlestone Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Ryde St Johns Road station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
