How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. In a small place like Upshire, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic in Upshire, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Typical jobs include sealant applied over dusty or wet surfaces and worktop and upstand sealant coming away, across show homes, bathrooms & en suites and kitchens.
For a small place like Upshire, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, you get the same one-year guarantee in Upshire and across Essex.

Quotes for new build mastic in Upshire
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- The number of rooms or windows
- The size of the job
- Whether old sealant or filler has to be cut out
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
When you call or email, it’s useful to know:
- Photos by email, if that is easy
- Where the property is
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

How to look after the new joints
Aftercare is simple:
- Keep water off fresh sealant until it has cured
- Don’t seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Joints and finishes in Upshire homes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Upshire, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Cheshunt station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Upshire
Is Upshire within the area you cover?
Yes. Upshire is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
