How we handle new build mastic in Luton

Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for cracks appearing as a new home settles and beads laid onto grit and dust from the build, across kitchens, windows & doors and show homes.

If you’ve bought a new home in or near Luton, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Different surfaces, different methods

Skirting and floors

New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Kitchens

Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.

What happens on the day

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. A visit to Luton is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
  • Tell us if parking is tricky

Why act early in Luton

Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a smaller place like Luton, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Why Luton clients choose us

  • We’re fully insured
  • White, clear, grey or another colour, product permitting

Common problems we fix in Luton

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.

Any of these means the joints need attention:

  • Plot mastic for developers ahead of handover
  • Gaps behind new kitchen upstands
  • Cracked sealant around new window and door frames
  • Smeared, uneven beads picked up at snagging

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

Before booking anyone

  • What guarantee comes with the work
  • How much experience the applicator has
  • Whether VAT is included
  • Is the old sealant removed completely?

Luton questions

Can you do new build mastic in Luton?

Yes. Our work covers London and the South East, and Luton is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

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

Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

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.

Can you quote for more than one area?

Yes. Just list everything you need and we’ll quote it together.

How long does new build mastic take?

Typically it takes anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we’ll tell you how long to expect.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.

Do you do commercial work?

Yes. Larger jobs can be planned room by room or area by area.

Keeping the joints in good condition

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

  • Raise failed sealant with the developer while you’re covered
  • Avoid running a DIY bead over the old one
  • Wipe joints with warm soapy water
  • Get a leaking seal dealt with right away

Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

New build mastic around Luton

Luton is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.

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