New build mastic for West Preston homes and businesses

What happens on the day

You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. A visit to West Preston is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
  • Mention if the joints have been sealed before

New build mastic for homes and businesses in West Preston

New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. Common call-outs are for leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, across show homes, kitchens and plot handovers.

In smaller places like West Preston, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.

Big or small, you get the same one-year guarantee.

Why act early in West Preston

A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a smaller place like West Preston, 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.

Your questions about new build mastic in West Preston

Can you help a landlord with a rental near Angmering station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Is West Preston within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you match the sealant colour to my new kitchen or bathroom?

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

Can I add another job to the visit?

Yes. More than one area can go on one quote.

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

Size, access and the old material all affect the cost. Call for a quick quote.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you work through snagging lists?

Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.

Should I wait before resealing?

Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How the job changes by surface

Windows and doors

The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.

West Preston is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. 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.
