Questions from East End
What guarantee comes with new build mastic in East End?
All our work, in East End and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you do new build mastic in East End?
Yes, East End is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How much does new build mastic cost in East End?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Why has my new-build shower seal failed already?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
How we handle new build mastic in East End
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We are often asked to deal with plot mastic for developers ahead of handover and beads laid onto grit and dust from the build, across plot handovers, kitchens and windows & doors.
Work in a small place like East End just needs the journey and access planning, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How it works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours in a single home for a typical job. Somewhere like East End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work

How we quote for new build mastic
Your quote is based on your job. We take into account:
- The type of sealant required
- The number of rooms or windows
- Any working-time requirements on site
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- The rough size of the job
- Whether it’s a home or a business
- Whether it has been sealed before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Around East End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When to call us in East End
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The problems people generally mention when they call are:
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Kitchen sealant that has pulled off the wall
Whether the job is in East End itself or nearby, the right material for each joint matters as much as a neat finish.
