About our new build mastic in Hacton

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. If you have frame joints opening as the plaster dries and shower seals failing in the first year or two, we can put it right.

Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Hacton and beyond.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What we are called out for in Hacton

Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.

Keep an eye out for any of the following:

  • Plot mastic for developers ahead of handover
  • Internal frame sealant that has split
  • Joints pulling apart as timber shrinks
  • Gaps between new skirting and floors

As a London address, Hacton can be tricky for parking: let us know about parking bays, permits or a driveway.

10 questions to ask before booking

New build mastic around Hacton

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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

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

Why act early in Hacton

The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Hacton.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Why book with us

  • Fully insured
  • A sealant colour to suit the surroundings
  • Every job guaranteed for a year
  • Experience in homes, commercial sites and hotels

Read our cost guide or what customers say.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Leaks from pipes, valves or wastes, which need a plumber
  • Deciding who is responsible under a builder’s warranty
  • Movement caused by a poorly fitted tray or bath

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

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

How it works

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In a London area like Hacton, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We look at why each joint failed, including any movement.
  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. The finished joints are checked and the cure times given.

How to prepare

  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts
  • Clear items away from the joints we’re working on

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

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.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Common questions in Hacton

Do you cover Hacton for new build mastic?

Yes, Hacton is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.

Is parking a problem for a job in Hacton?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

How long does new build mastic take?

A typical job takes anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

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

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

What affects the quote in Hacton

We don’t publish a price list, because no two jobs are the same. What we look at:

  • The old material and how stubborn it is
  • Mould in or behind the old joints
  • The number and length of the joints
  • When we can work, for business premises

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Helping us quote

To make quoting easier, let us know:

  • If someone has resealed it before
  • Access, such as stairs, a lift or height
  • The type of property
  • The problem you’ve noticed

To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
