About our new build mastic in Norton

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Typical jobs include gaps behind new kitchen upstands and messy sealant that spoils new finishes, across plot handovers, skirting & floors and kitchens.

For a small place like Norton, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods

Bathrooms and en suites

New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Kitchens

Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.

New homes and floors in Norton

Norton is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.

If you’ve bought a new home near Bishopstone (Sussex) station, the sealant around baths, showers and frames is worth checking in the first year or two.

Honest limits

In fairness, some problems need a different trade:

  • Cracking that points to a structural problem
  • Broken tiles or a split tray
  • A tray or bath that is not properly supported, until it’s fixed

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Clean sealant with mild detergent, not abrasives
  • Follow the cure time we give you
  • Report sealant problems to your builder during the snagging period
  • Record problems with dated pictures

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.

Norton questions

Is Norton within the area you cover?

Yes, Norton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Norton in your area for new build mastic?

Yes. We work across London and the South East, and Norton is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.

Do you do commercial work?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

Can you match the sealant colour to my new kitchen or bathroom?

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

Do you have insurance?

Yes, we are fully insured for domestic and commercial work.

Do you work through snagging lists?

Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We’ll tell you if anything on it isn’t a sealant job.

How long will you be here?

It depends on the size of the job, but most jobs take a few hours in a single home. We’ll tell you when we quote.

Can new sealant go on top of the old bead?

No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.

What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a small place like Norton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Finally, each room is checked and you’re given the cure time.

Before we arrive

  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
  • Tell us if parking is tricky

Why it’s worth doing now in Norton

If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Older cottages and farmhouses around Norton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Why book with us

  • Anti-fungal silicone where joints get wet
  • An ARBOMaster approved applicator
  • A choice of colours where the product allows
  • Trusted Arbo and Everbuild sealants

Common problems we fix in Norton

A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.

It’s worth asking for a quote if you see:

  • New-build shower sealant that has already split
  • Untidy sealant flagged on a snagging list
  • Beads laid onto grit and dust from the build
  • Frame joints opening as the plaster dries

In and around Norton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Questions to ask before you book

  • How the surfaces are prepared before sealing
  • Which sealant they’ll use, and why
  • Are they insured?
  • Whether VAT is included
