What affects the quote in Hailsham

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

  • Working hours on commercial sites
  • The product the joint needs
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

You do not need to know the technical terms. Just tell us:

  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved

We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.

How we handle new build mastic in Hailsham

A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have skirting joints opening in the first winter and beads laid onto grit and dust from the build, we can help.

Shops and business units around Hailsham have floors that see a lot of traffic. Threshold and floor joints are best resealed before their edges start breaking away.

Every job is covered by a one-year guarantee.

What the job involves on each surface

Windows and doors

A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.

Skirting and floors

Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.

Common questions in Hailsham

What guarantee comes with new build mastic in Hailsham?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

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

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Can new sealant go on top of the old bead?

No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.

What do you need from me for a quote?

A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.

Do you use white or clear sealant?

Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.

Can you do plot mastic on a new development?

Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.

How do I get a quote for new build mastic in Hailsham?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.

Do you work through snagging lists?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.

New build mastic in Hailsham: local notes

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.

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

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Open a window or run the fan after bathing
  • Get a leaking seal dealt with right away
  • Report sealant problems to your builder during the snagging period
  • Photograph failed sealant before it’s redone

Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.

Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.

Common problems we fix in Hailsham

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.

These are the problems we’re asked about most:

  • New-build shower sealant that has already split
  • Kitchen sealant that has pulled off the wall
  • Skirting joints opening in the first winter
  • Sealant that never bonded to the surface

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

Questions to ask before booking

  • What happens if the job turns out different
  • How the colour is chosen
  • Who turns up on the day
  • The length of the guarantee

Choosing a sealant specialist

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. For a job in Hailsham, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Keep children and pets away from the work area
  • For business premises, tell us about site rules or sign-in

Getting a quote
