Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.

How we handle new build mastic in Grays

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We are often asked to deal with gaps behind new kitchen upstands and messy sealant that spoils new finishes, on kitchens, windows & doors and bathrooms & en suites.

In a town like Grays, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.

Each job carries a 12-month guarantee, large or small.

What we can’t put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Movement caused by a poorly fitted tray or bath
  • Leaks from pipes, valves or wastes, which need a plumber
  • Cracked trays, tiles or worktops

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Grays questions

Do you work for landlords with property near Grays station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Do you cover Grays for new build mastic?

Yes. We work across London and the South East, and Grays is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.

Is it normal for sealant to crack in a new home?

There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

My new home is still under warranty. Should I contact you?

Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.

Can I add another job to the visit?

Of course. Doing several areas at once is usually more efficient.

When is the best time to reseal in a new build?

Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.

Do you guarantee your work?

Yes, always. There’s a 12-month guarantee on every job.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Use the extractor fan every time you shower
  • Don’t seal over failed sealant yourself
  • Check bath and shower seals every few months as the house settles
  • Wipe joints with warm soapy water

Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.

Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

Why it’s worth doing now in Grays

DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In Grays, as anywhere, most leaks start as a small gap in a joint, and early is when they’re cheapest and quickest to sort.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

New homes and floors in Grays

Grays is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you’ve bought a new home near Grays station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Grays, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day

Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. A visit in Grays needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.

  1. First we work through your snagging list or plot schedule with you.
  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. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you are given the cure time.

Before we arrive

  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
