How the visit works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours in a single home. Jobs in a place the size of Basildon range from town-centre flats to offices and family homes. Whichever it is, tell us how to get in, where to park and where the work is.

  1. Each joint is checked for movement before work begins.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  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

  • Mention any tricky access
  • Mention any parking rules near the property
  • Try not to wet indoor joints just before the visit

New build mastic in Basildon, done properly

Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, we can put it right, whatever the surface.

Plenty of homes in Basildon are on estates built in the last few decades, where the builder’s original sealant around baths, frames and skirtings may be due for replacing. We work for developers on plot mastic and for owners on snagging.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Different surfaces, different methods

Skirting and floors

Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.

Bathrooms and en suites

En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

When to call us in Basildon

On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.

Most people get in touch when they notice something like this:

  • Smeared, uneven beads picked up at snagging
  • Shower seals failing in the first year or two
  • Internal frame sealant that has split
  • Second-fix sealing on new plots

Around Basildon, as everywhere, new build mastic is only as good as the preparation behind it.

Questions to ask before booking

  • How the surfaces are prepared before sealing
  • What insurance they hold
  • How long to leave it before use
  • Whether all the old sealant comes out first

How to choose a mastic man

Leave it or put it right?

For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. In a large rental market like Basildon, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Why Basildon clients choose us

  • Colour agreed with you before any work starts
  • White, clear, grey or coloured to suit, where the product allows
  • Experience in homes, commercial sites and hotels
  • Approved under the ARBOMaster scheme

Should I try it myself first?

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

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.

Joints and finishes in Basildon homes

Basildon is one of the post-war new towns. Basildon has kept growing, with newer neighbourhoods added to the original town. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you’ve bought a new home near Basildon station, the sealant around baths, showers and frames is worth checking in the first year or two.

Basildon questions

Can you do new build mastic in Basildon?

Yes. We work across London and the South East, and Basildon is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

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

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

Can you reseal over the builder’s sealant?

No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.

Why does sealant fail so quickly in new builds?

New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.

How long does new build mastic take?

Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.

What information do you need?

Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

What affects the quote in Basildon

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

  • Any working-time requirements on site
  • How many areas need sealing
  • How easy the joints are to reach
  • The size of the job

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. You’ll know the price before we begin.

What we need to know

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Photos by email, if that is easy
  • Where the job is, and your postcode
  • What’s wrong with the joints now
  • The rough size of the job

Need a quote? Please call 0345 464 0079 or email us and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.

What sealant work cannot fix

New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:

  • Damaged fittings that need replacing
  • Disputes or warranty claims with your builder
  • Leaks from pipes, valves or wastes, which need a plumber

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