FAQs for Pondwell
I let a flat near Smallbrook Junction station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Pondwell?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
Are you fully insured?
Yes. We’re fully insured for every job we do.
External mastic in Pondwell, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Common call-outs are for movement joints with cracked, split or missing sealant and plants rooting in failed movement joints, across façade panels, joints between brick and frames and copings & trims.
Somewhere as small as Pondwell, homes and farm buildings often face open ground, 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.
You get a one-year guarantee, the same in Pondwell as everywhere else we work.

What else we do in Pondwell
What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. In a small place like Pondwell, access is usually the main thing to plan. 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.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Let us know about parking restrictions

Related advice
Common problems we fix in Pondwell
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The problems people generally mention when they call are:
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Failed seals between different materials
If you look after a building such as Nettlestone Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How we quote for external mastic
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- The number and length of the joints
- The type of sealant required
- The number of rooms or windows
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- If someone has resealed it before
- How we’d reach the joints
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or send us an email and describe the job, and photos are welcome.
Why act early in Pondwell
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a small place like Pondwell, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

External mastic in Pondwell: local notes
Pondwell is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around St. Peter's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Smallbrook Junction station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
