About our new build mastic in Whatlington

We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We’re often asked to deal with plot mastic for developers ahead of handover and internal frame sealant that has split, across windows & doors, plot handovers and bathrooms & en suites.

In a village or hamlet like Whatlington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Your job is guaranteed for a year, as with all our work.

Can I do it myself?

A careful DIYer can reseal a simple joint, 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.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you need new build mastic in Whatlington?

Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.

The problems people generally mention when they call include:

  • Cracked caulk along new skirting
  • Sealant that never bonded to the surface
  • Gaps behind new kitchen upstands
  • Sealant work across a run of new homes

Around Whatlington, as everywhere, new build mastic is only as good as the preparation behind it.

How to choose a mastic man

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Ventilate bathrooms well, especially in the first year
  • Follow the cure time we give you
  • Watch for new gaps as the house dries out
  • Resist patching a failed seal with a tube from the DIY shop

Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.

A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

What the job involves on each surface

Windows and doors

On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.

In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.

Quotes for new build mastic in Whatlington

Your quote is based on your job. We look at:

  • Whether there’s mould to deal with
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site

What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

What we need to know

When you contact us, these details help:

  • Where the job is, and your postcode
  • Photos by email, if that is easy
  • Access, such as stairs, a lift or height
  • Any previous sealing or DIY work

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

Honest limits

New sealant can’t fix everything, and we’d rather say so up front. It will not solve:

  • Movement caused by a poorly fitted tray or bath
  • Broken tiles or a split tray
  • Cracking that points to a structural problem

If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Whatlington questions

Is Whatlington within the area you cover?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

I let a flat near Battle station. Can you help?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

How do I get a quote for new build mastic in Whatlington?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

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

Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room before we begin.

Who should fix failed sealant in a new build?

Your builder, if you are still in their snagging or warranty period. If that does not work out, we’re happy to quote.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Whatlington, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked for movement before we start.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

How to prepare

  • Clear the area around the work
  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive
