What affects the cost of new build mastic

We quote each job individually. This is what makes a difference:

  • How many areas need sealing
  • Whether there’s mould to deal with
  • The size of the job
  • How much old sealant there is and how hard it is to remove

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What we need to know

When you contact us, it’s useful to know:

  • The problem you’ve noticed
  • The type of property
  • How we’d reach the joints
  • Whether it has been sealed before

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and give you a clear quote.

About our new build mastic in Swanton

In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, windows & doors and plot handovers, and common reasons people get in touch are untidy sealant flagged on a snagging list and gaps behind new kitchen upstands.

For a small place like Swanton, the journey and access are planned in advance, and the work itself is the same as on any site.

Every job is covered by a 12-month guarantee, wherever you are in Kent.

Common questions in Swanton

Can you do new build mastic in Swanton?

Yes. We work across London and the South East, and Swanton is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Will you come out to Swanton?

Yes, Swanton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

I’m a tenant. Can you help?

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

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you take on second-fix sealing for builders?

Yes. We work through plots to your schedule. Tell us the plots and the joints involved and we will quote.

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. Either can make it fail early.

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

No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Landlords, agents and businesses in Swanton

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Signs you need new build mastic in Swanton

Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.

It’s worth asking for a quote if you see:

  • Plot mastic for developers ahead of handover
  • Kitchen sealant that has pulled off the wall
  • Messy sealant that spoils new finishes
  • Beads laid onto grit and dust from the build

For new homes near Wateringbury station, it’s worth checking the sealant early, while snags are still fresh.

When something else is needed

We won’t take on work that will not last, so these are the limits:

  • Baths and trays that move too much for sealant to cope with
  • Plumbing faults behind the sealant
  • Damaged fittings that need replacing

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

How the visit works

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. For a village or hamlet like Swanton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  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.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in

Related advice

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Why deal with it now?

A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In a small place like Swanton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
