What we need to know

What to tell us when you ask for a quote:

  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business
  • Where the property is
  • Any access issues, like height or stairs

How we handle new build mastic in Haggerston

In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have new-build shower sealant that has already split and gaps behind new kitchen upstands, we can put it right, whatever the surface.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

Every job comes with our one-year guarantee.

How the job changes by surface

Windows and doors

Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.

Kitchens

Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.

Common questions in Haggerston

Do you cover Haggerston for new build mastic?

Yes, Haggerston is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.

Can parking be tricky for a visit in Haggerston?

Parking in Haggerston, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Do you work for hotels and businesses?

Yes. We can plan bigger jobs in stages.

Do you use white or clear sealant?

The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Aftercare tips

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

  • Don’t wait for the house to settle if water is getting through
  • Raise failed sealant with the developer while you are covered
  • Watch for new gaps as the house dries out
  • Use the extractor fan every time you shower

Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.

Early snagging is easier snagging. Left alone, a small crack can become a leak.

The process

We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. For a job in Haggerston, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. The old bead comes out in full, with no layer left behind.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  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.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Tell us about access, such as stairs, a lift or high-level joints
  • Move anything stored near the joints

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

When something else is needed

Sealant isn’t the answer to every problem, and we will tell you before work begins. It will not solve:

  • Leaking fittings rather than failed sealant
  • Deciding who is responsible under a builder’s warranty
  • Damaged fittings that need replacing

If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

Surfaces we seal

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

Common problems we fix in Haggerston

The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.

The most common problems we see are:

  • Worktop and upstand sealant coming away
  • Beads laid onto grit and dust from the build
  • Second-fix sealing on new plots
  • Frame joints opening as the plaster dries

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