New build mastic for Littleworth homes and businesses

New build mastic for homes and businesses in Littleworth

Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on show homes, skirting & floors and plot handovers, and the jobs we see most are second-fix sealing on new plots and skirting joints opening in the first winter.

Around Littleworth, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

You get a one-year guarantee, the same in Littleworth as everywhere else we work.

Keeping the joints in good condition

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

  • Don’t seal over failed sealant yourself
  • Keep water off fresh sealant until it has cured
  • Wipe joints with warm soapy water
  • Check bath and shower seals every few months as the house settles

Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.

Surface by surface

Kitchens

Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Your questions about new build mastic in Littleworth

Can you do new build mastic in Littleworth?

Yes. Our work covers London and the South East, and Littleworth is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Is new build mastic in Littleworth guaranteed?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you reseal over the builder’s sealant?

No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.

Do you have insurance?

Yes. Full insurance covers our work.

Why does sealant fail so quickly in new builds?

Lots of new homes see sealant crack early. Poor preparation at handover adds to it.

How long should I leave it?

It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.

New homes and floors in Littleworth

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. In a small place like Littleworth, access is normally 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 work begins.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Before we arrive

  • Clear items away from the joints we’re working on
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know if you’ve seen damp or leaks

What happens if it’s left?

A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few photos and we’ll give you a straight answer. Where a wall is exposed, as many are in small places like Littleworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What sealant work can’t fix

Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant won’t put right:

  • Broken tiles or a split tray
  • Disputes or warranty claims with your builder
  • Baths and trays that move too much for sealant to cope with

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

Surfaces we seal

Can I do it myself?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
