New build mastic for South Street homes and businesses

New build mastic in South Street

For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on bathrooms & en suites, windows & doors and show homes, and common reasons people get in touch are smeared, uneven beads picked up at snagging and worktop and upstand sealant coming away.

In a village or hamlet like South Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

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

What happens if it’s left?

A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, call 0345 464 0079 or drop us an email with photos. Around South Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Why South Street clients choose us

  • One-year guarantee on every job
  • An ARBOMaster approved applicator

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Use the extractor fan every time you shower
  • Watch for new gaps as the house dries out
  • Record problems with dated pictures
  • Avoid scourers and strong chemicals on sealant

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.

Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.

What the job involves on each surface

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.

Kitchens

As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.

Work for landlords, hotels and businesses

Landlords and agents in South Street can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.

New build mastic around South Street

Questions from South Street

Is South Street in your area for new build mastic?

Yes, South Street is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.

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

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.

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

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email and tell us what needs doing and where.

Will you just run a new bead over the existing one?

No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.

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

New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.

How the visit works

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours in a single home. Somewhere like South Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  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.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in

Ask for a quote

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or email us.

When something else is needed

To be straight with you, some problems need a different trade:

  • Deciding who is responsible under a builder’s warranty
  • Broken tiles or a split tray
