How we handle new build mastic in World's End

A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on plot handovers, bathrooms & en suites and skirting & floors, and common reasons people get in touch are skirting joints opening in the first winter and internal frame sealant that has split.

In smaller places like World's End, 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.

Your job is guaranteed for a year, as with all our work.

What the job involves on each surface

Windows and doors

External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.

Bathrooms and en suites

New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

When it isn’t the sealant

To be straight with you, there are a few things sealant won’t fix:

  • Baths and trays that move too much for sealant to cope with
  • Structural cracks in walls or ceilings
  • Your warranty claim itself, which is between you and the builder

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

What we seal

  • Windows & doors

How we quote for new build mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The number and length of the joints
  • The number of rooms or windows
  • Access and height
  • How much old sealant there is and how hard it is to remove

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

When you contact us, these details help:

  • The type of property
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved

To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.

Why act early in World's End

For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In an older home around World's End, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What happens on the day

At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours in a single home, depending on the amount of work. For a job in World's End, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Clear items away from the joints we are working on
  • Let us know about parking restrictions

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Get a leaking seal dealt with straight away
  • Record problems with dated pictures
  • Look at the sealant regularly in the first couple of years
  • Avoid running a DIY bead over the old one

Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.

Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.

FAQs for World's End

Do you work for landlords with property near Wivelsfield station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.

Will you come out to World's End?

Yes. World's End is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

What colour sealant will you use?

It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.

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.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Should I wait before resealing?

It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.

My new home is still under warranty. Should I contact you?

Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we will cut it out and reseal it.
