New build mastic in Goodmayes, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on show homes, kitchens and plot handovers, and the jobs we see most are worktop and upstand sealant coming away and joints pulling apart as timber shrinks.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Goodmayes and beyond.
Big or small, you get the same 12-month guarantee.

When it is not the sealant
To be straight with you, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

Why it’s worth doing now in Goodmayes
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a flat in Goodmayes, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- The number of rooms or windows
- Which sealant suits the joint
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved

What new build mastic looks like in Goodmayes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Goodmayes station, the sealant around baths, showers and frames is worth checking in the first year or two. As a London address, Goodmayes can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What happens on the day
We keep the work tidy and contained to the joints we are treating. Expect the work to take a few hours for most snagging lists, longer for a run of plots. In a London area like Goodmayes, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What does new build mastic cost?
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. We agree the price before any work begins.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
