New build mastic for Cross in Hand homes and businesses

New build mastic for homes and businesses in Cross in Hand

Across Cross in Hand, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on plot handovers, skirting & floors and kitchens, and people most often call us about plot mastic for developers ahead of handover and cracked sealant around new window and door frames.

Somewhere as small as Cross in Hand, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Why act early in Cross in Hand

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Cross in Hand, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Why book with us

  • We leave the area clean and tidy
  • Sealant colour chosen to suit

  • We are fully insured

How the job changes by surface

Bathrooms and en suites

En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We’ll plan around viewing times.

Looking after it afterwards

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

  • Resist patching a failed seal with a tube from the DIY shop
  • Open a window or run the fan after bathing
  • Keep photos and emails about snagging items
  • Get a leaking seal dealt with right away

Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.

Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Joints and finishes in Cross in Hand homes

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you’ve bought a new home near Buxted station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Cross in Hand, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Cross in Hand: your questions answered

Is Cross in Hand within the area you cover?

Yes, Cross in Hand is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you cover Cross in Hand for new build mastic?

Yes. We work across London and the South East, and Cross in Hand is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.

Can you do plot mastic on a new development?

Yes. We work through plots to your schedule, room by room. Get in touch with the number of plots and the scope for a clear quote.

Is it worth resealing while the house is still settling?

If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.

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

Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.

Do you work through snagging lists?

Yes. Send it with photos and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we’ll quote it together.

The process

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Cross in Hand, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We check every joint and tell you how long each needs to cure.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work

Advice

What sealant work can’t fix

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Movement caused by a poorly fitted tray or bath
  • Leaks from pipes, valves or wastes, which need a plumber
  • Deciding who is responsible under a builder’s warranty

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
