  • Beads laid onto grit and dust from the build

New build mastic for Basted homes and businesses

Different surfaces, different methods

Windows and doors

Draughts around new frames are often a sealant gap. We check and reseal the frame edges.

Bathrooms and en suites

Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.

How we handle new build mastic in Basted

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on bathrooms & en suites, kitchens and show homes, and the jobs we see most are messy sealant that spoils new finishes and joints pulling apart as timber shrinks.

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

A 12-month guarantee comes as standard.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. For a village or hamlet like Basted, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at why each joint failed, including any movement.
  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.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions
  • Move anything stored near the joints

Advice

What affects the quote in Basted

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • Any mould that needs treating
  • How much there is to do
  • How much old sealant there is and how hard it is to remove

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Asking for a quote

To make quoting easier, please include:

  • The problem you’ve noticed
  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • The address or postcode of the job

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

Why it’s worth doing now in Basted

Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few pictures. In a small place like Basted, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

What you get with us

  • Sealant colour chosen to suit
  • Over 20 years’ experience
  • We agree the colour with you first
  • Old sealant always removed completely

Basted: your questions answered

Do you cover smaller places like Basted?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you help a landlord with a rental near Borough Green & Wrotham station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Do you take on second-fix sealing for builders?

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

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

When is the best time to reseal in a new build?

For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

My new home is still under warranty. Should I contact you?

Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote with our 12-month guarantee.

How long should I leave it?

It depends on the product and the conditions. We tell you how long to leave it before we go.

When to call us in Basted

The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.

Keep an eye out for any of the following:

  • Cracks appearing as a new home settles
  • Messy sealant that spoils new finishes
  • Gaps between new skirting and floors
  • Second-fix sealing on new plots

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

Questions to ask before booking

  • The length of the guarantee
  • Whether VAT is included
  • How much experience the applicator has
  • Whether they seal over old material or remove it

How to choose a mastic man

Should I try it myself first?

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 fails, we can still redo it.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

When it is not the sealant

It helps to know what we can’t do too:

  • Damaged fittings that need replacing
  • Structural cracks in walls or ceilings
  • Leaks from pipes, valves or wastes, which need a plumber

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What we seal

  • Skirting & floors
  • Kitchens
  • Show homes
  • Plot handovers
  • Bathrooms & en suites
  • Windows & doors
