When something else is needed

- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

How we handle external mastic in Privett
Getting the depth right is half the job. 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. We work on brickwork movement joints, concrete & block and joints between brick and frames, and common reasons people get in touch are plants rooting in failed movement joints and joints where the bead has come unstuck.
Somewhere as small as Privett, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Privett, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Deal with leaking gutters that soak the joints below
- Show decorators and builders where the movement joints are
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Privett buildings and the weather
With historic houses such as Hinton Ampner House (about 5 miles west) nearby, there’s older building stock in the area around Privett as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Holy Trinity Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Petersfield station? Then split movement joints are easy to miss on a rental until damp shows inside.

Common questions in Privett
I let a flat near Petersfield station. Can you help?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Privett, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach 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 call for the right materials, safe access and experience.
