New build mastic in Hever

Why act early in Hever

Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few pictures. Where a wall is exposed, as many are in small places like Hever, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Why Hever clients choose us

  • Colour agreed with you before we start
  • 20+ years of sealant experience
  • White, clear, grey or another colour, product permitting
  • We’re fully insured

New build mastic in Hever

We work in new homes and on new-build sites across Hever. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. Typical jobs include joints pulling apart as timber shrinks and sealant work across a run of new homes, on plot handovers, kitchens and show homes.

Work in a small place like Hever just needs the journey and access planning, and once on site, the job is the same as anywhere.

Our work is backed for twelve months, in Hever and everywhere else we cover.

What affects the quote in Hever

We quote each job individually. These are the things that affect it:

  • The type of sealant required
  • Whether there’s mould to deal with
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Helping us quote

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

  • A few pictures by email, if you can
  • If it’s domestic, commercial or a hotel
  • Whether it has been sealed before
  • Where the property is

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

When it isn’t the sealant

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Settlement cracks that need a surveyor
  • Damaged fittings that need replacing
  • Disputes or warranty claims with your builder

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

What we seal

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

How the job changes by surface

Kitchens

Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Bathrooms and en suites

Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.

What happens on the day

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home and we leave things clean and tidy. For a village or hamlet like Hever, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Preparing for the visit

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • On commercial sites, let us know about site rules

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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

Hever: your questions answered

Will you come out to Hever?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is Hever in your area for new build mastic?

Yes, Hever is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Are you insured?

Yes. We’re fully insured for domestic and commercial work.

When is the best time to reseal in a new build?

If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.

Will you just run a new bead over the existing one?

No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.

Do you use white or clear sealant?

Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.

Can I send you my snagging list?

Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.

Signs you need new build mastic in Hever

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.

Any of these means the joints need attention:

  • Sealant that never bonded to the surface
  • Messy sealant that spoils new finishes
  • Gaps behind new kitchen upstands
  • Gaps opening as the house dries out and settles

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

Before you book anyone

  • Whether you can choose the colour
  • Whether they’re fully insured
  • How the joint is cleaned and prepared
  • When the joint can take water or movement
