New homes and floors in Sevenscore

Sevenscore 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Around Sevenscore, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Thanet Parkway station, it’s worth checking the sealant early, while snags are still fresh.

Sevenscore is about 3 miles west of Ramsgate, in Kent. Sevenscore gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

New build mastic in Sevenscore, done properly

New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on windows & doors, show homes and skirting & floors, and common reasons people get in touch are new-build shower sealant that has already split and second-fix sealing on new plots.

Older homes in small places like Sevenscore often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Our work is backed for twelve months.

How the job changes by surface

Plot handovers

Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.

Skirting and floors

Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.

Leave it or put it right?

For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Where a wall is exposed, as many are in small places like Sevenscore, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Photograph failed sealant before it’s redone
  • Keep water off fresh sealant until it has cured
  • Watch for new gaps as the house dries out
  • Ventilate bathrooms well, especially in the first year

Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.

Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.

What affects the cost of new build mastic

You will get a clear quote before any work starts. It takes into account:

  • How many rooms, windows or areas are involved
  • The type of sealant required
  • Any mould that needs treating
  • When we can work, for business premises

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we need to know

When you contact us, these details help:

  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height
  • The address or postcode of the job
  • The type of property

How it works

At the end, we look at the finished work together. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Sevenscore, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  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.

Before we arrive

  • Clear the area around the work
  • Let us know about earlier repairs to the joints
  • Tell us about access, such as stairs, a lift or high-level joints

What we cannot put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Disputes or warranty claims with your builder
  • Damaged fittings that need replacing
  • Leaking fittings rather than failed sealant

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
