New build mastic in Kent Street
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have beads laid onto grit and dust from the build and joints pulling apart as timber shrinks, we can put it right, on show homes, kitchens and plot handovers alike.
For a small place like Kent Street, the journey and access are planned in advance, and the work itself is the same as on any site.
Whatever the size of the job, it’s backed by our one-year guarantee in Kent Street and across East Sussex.

Keeping the joints in good condition
Looking after new joints is easy:
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Keep photos and emails about snagging items
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.

Why deal with it now?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Around Kent Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Is Kent Street 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.
Do you cover Kent Street for new build mastic?
Yes, Kent Street is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
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.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you use white or clear sealant?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.

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

- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings

Advice
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
