New build mastic in Sutton at Hone
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Typical jobs include beads laid onto grit and dust from the build and second-fix sealing on new plots, on bathrooms & en suites, skirting & floors and windows & doors.
Somewhere as small as Sutton at Hone, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What the job involves on each surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours in a single home in most cases.

- We start by going through the snagging items or plot schedule with you.

What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.

We’re based in Crawley, and we work across South East England, London and Scotland.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.

Why act early in Sutton at Hone
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In a small place like Sutton at Hone, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Common problems we fix in Sutton at Hone
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Keep an eye out for any of the following:
- Kitchen sealant that has pulled off the wall
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Second-fix sealing on new plots
For new homes near Farningham Road station, it’s worth checking the sealant early, while snags are still fresh.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Windows & doors
- Bathrooms & en suites
- Skirting & floors
- Kitchens
- Plot handovers

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Keep pictures and emails about snagging items
- Put sealant faults on your snagging list early
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
