East Hill questions
I let a flat near Shoreham (Kent) station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is East Hill within the area you cover?
Yes. East Hill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room before we begin.
New build mastic in East Hill
We work in new homes and on new-build sites across East Hill. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you have new-build shower sealant that has already split and smeared, uneven beads picked up at snagging, we can put it right.
Around East Hill, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, you get the same one-year guarantee in East Hill and across Kent.

How the job changes by surface
Plot handovers
Send us the schedule and any sealant specification and we will quote. We seal bathrooms, kitchens, frames and floors.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
The process
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home. In a small place like East Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Joints and finishes in East Hill homes
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.

Do you need new build mastic in East Hill?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
People generally contact us after spotting one of these:
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
For new homes near Shoreham (Kent) station, it’s worth checking the sealant early, while snags are still fresh.

- How the surfaces are prepared before sealing

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not seal over failed sealant yourself
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few photos and we will give you a straight answer. Around East Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
