What affects the cost of new build mastic

Call for a quick quote. What matters most is:

  • How easy the joints are to reach
  • The size of the job
  • Any working-time requirements on site
  • The number of rooms or windows

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

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • The type of property
  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the property is

There’s no standard price list. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or email us.

How we handle new build mastic in West Mersea

For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you’re dealing with new-build shower sealant that has already split and sealant work across a run of new homes, we can help, whatever the surface.

For a new home in or near West Mersea, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

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

When to call us in West Mersea

Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.

Most people get in touch after spotting one of these:

  • Gaps behind new kitchen upstands
  • Joints pulling apart as timber shrinks
  • New-build shower sealant that has already split
  • Frame joints opening as the plaster dries

In and around West Mersea, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Our hiring checklist

What happens if it’s left?

Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Around West Mersea, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

Why us?

  • White, clear, grey or another colour, product permitting
  • Colour picked to suit the job
  • Colour agreed with you before any work starts
  • Homes, businesses and hotels

Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Common questions in West Mersea

Is new build mastic in West Mersea guaranteed?

All our work, in West Mersea and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Can you do new build mastic in West Mersea?

Yes. We work across London and the South East, and West Mersea is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What colour sealant will you use?

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

Why has my new-build shower seal failed already?

It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.

Should I go to my builder first?

Start with the builder if you are in the snagging or warranty period. Once that is done, or if they will not put it right, we can reseal it properly.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

New homes and floors in West Mersea

West Mersea is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Whether the job is in West Mersea itself or nearby, the right material for each joint matters as much as a neat finish.

How the visit works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. Parking around West Mersea is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. First we work through your snagging list or plot schedule with you.
  2. The old bead comes out in full, with no layer left behind.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. We check every joint and tell you how long each needs to cure.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
