Why act early in Ditchling

A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few photos. Where a wall is exposed, as many are in small places like Ditchling, 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 price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • Colour picked to suit the job
  • Neat joints and a tidy finish
  • We never seal over old sealant
  • Sanitary silicone with an anti-fungal additive in wet areas

New build mastic for homes and businesses in Ditchling

We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on show homes, skirting & floors and plot handovers, and common reasons people get in touch are untidy sealant flagged on a snagging list and leaking shower tray seals in a new home.

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

Your job is guaranteed for a year, as with all our work.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. For a village or hamlet like Ditchling, 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. Each joint is checked for movement before any work starts.
  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. We check every joint and leave you with the cure times.

Preparing for the visit

  • Mention any parking rules near the property
  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you are set on DIY, put the effort into 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.

Aftercare tips

So the new joints stay in good condition:

  • Photograph failed sealant before it’s redone
  • Avoid scourers and strong chemicals on sealant
  • Act quickly if a seal starts to leak
  • Check bath and shower seals every few months as the house settles

Watch the joints as the house settles. Small gaps can appear as the house dries.

If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Questions from Ditchling

Is Ditchling within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is Ditchling in your area for new build mastic?

Yes, Ditchling is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Can tenants book the work?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What does new build mastic cost?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Do you work for letting agents?

Yes. We work for householders, landlords, letting agents, businesses and hotels.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Plumbing faults behind the sealant
  • Movement caused by a poorly fitted tray or bath
  • Cracking that points to a structural problem

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

What affects the cost of new build mastic

There’s no set price list. What we look at:

  • The size of the job
  • Mould in or behind the old joints
  • The type of sealant required
  • Working hours on commercial sites

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Whether it has been sealed before
  • A few photos by email, if you can
  • The address or postcode of the job
  • Roughly how big the job is

For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.

How the job changes by surface

Skirting and floors

Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.

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.
