Joints and finishes in Norbiton homes

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

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

How we handle new build mastic in Norbiton

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on bathrooms & en suites, windows & doors and show homes, and the jobs we see most are plot mastic for developers ahead of handover and sealant applied over dusty or wet surfaces.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Signs you need new build mastic in Norbiton

Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry first.

It’s worth asking for a quote if you see:

  • Second-fix sealing on new plots
  • Beads laid onto grit and dust from the build
  • Leaking shower tray seals in a new home
  • Skirting joints opening in the first winter

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

What your quote should include

  • Whether the sealant suits the joint
  • What happens if they find a problem under the old sealant
  • Whether they’re fully insured
  • How the colour is chosen

Our hiring checklist

Why deal with it now?

Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you are unsure which you have, ring 0345 464 0079 or email us with photos and we will tell you. In a flat in Norbiton, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Rather than a set price list, 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 you get with us

  • White, clear, grey or another colour, product permitting
  • Anti-fungal silicone where joints get wet
  • Fully insured
  • 20+ years of sealant experience

See how sealant jobs are priced or customer reviews.

Should I try it myself first?

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 fails, we can still redo it.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

When something else is needed

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Structural cracks in walls or ceilings
  • Disputes or warranty claims with your builder
  • Baths and trays that move too much for sealant to cope with

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Surfaces we seal

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

What happens on the day

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. In Norbiton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  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. A sealant chosen for each area goes in and is tooled smooth.
  5. Each area is checked and left with its cure time.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Clear the area around the work
  • Mention if the joints have been sealed before
