Joints and finishes in Horsemere Green homes
Horsemere Green is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Horsemere Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Ford station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours in a single home. Somewhere like Horsemere Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

What affects the cost of new build mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- How easy the joints are to reach
- The type of sealant required
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
To make quoting easier, let us know:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- The rough size of the job
- Pictures of the joints, sent by email

Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.

It depends on the size of the job, but most jobs take a few hours in a single home. We will give you a better idea when we quote.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you are covered
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. Older cottages and farmhouses around Horsemere Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
