Common questions in Saint Hill Green
Is Saint Hill Green within the area you cover?
Yes. Saint Hill Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Saint Hill Green?
Yes, Saint Hill Green is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
What colour sealant will you use?
White and clear are the most common, but other colours are available. We choose one to suit the room before we begin.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
New build mastic in Saint Hill Green
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you’re dealing with gaps opening as the house dries out and settles and gaps between new skirting and floors, we can put it right, on plot handovers, bathrooms & en suites and show homes alike.
Older homes in small places like Saint Hill Green often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, it’s backed by our 12-month guarantee in Saint Hill Green and across West Sussex.

What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Saint Hill Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. For a village or hamlet like Saint Hill Green, 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.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive

What else we do in Saint Hill Green
Common problems we fix in Saint Hill Green
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry before the sealant goes on.
The most common problems we see are:
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
Around Saint Hill Green, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Whether all the old sealant comes out first
- Whether you can choose the colour
- Whether the sealant suits the joint
- When the joint can take water or movement
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the quote in Saint Hill Green
We quote each job individually. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Any working-time requirements on site
- How many areas need sealing
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- Where the property is
- The problem you’ve noticed
- Roughly how big the job is
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
