Your questions about new build mastic in Castle Hedingham
Will you come out to Castle Hedingham?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We will tell you if anything on it isn’t a sealant job.
How long does new build mastic take?

Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
New build mastic in Castle Hedingham, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Typical jobs include messy sealant that spoils new finishes and sealant applied over dusty or wet surfaces, across windows & doors, show homes and kitchens.
In a village or hamlet like Castle Hedingham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Every job comes with a one-year guarantee.

Common problems we fix in Castle Hedingham
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
Any of these means the joints need attention:
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Second-fix sealing on new plots
Around Castle Hedingham, as everywhere, new build mastic is only as good as the preparation behind it.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are 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 doesn’t work out, we can still put it right.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Castle Hedingham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

- Trusted Arbo and Everbuild sealants
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows

How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. For a village or hamlet like Castle Hedingham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
