New build mastic for homes and businesses in Bossingham
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you’re dealing with kitchen sealant that has pulled off the wall and skirting joints opening in the first winter, we can help.
Somewhere as small as Bossingham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee, whatever its size.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
The process
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours in a single home, and we explain the cure time before we leave. In a small place like Bossingham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- 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
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Signs you need new build mastic in Bossingham
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.
Keep an eye out for any of the following:
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
If you’ve bought a new home near Chartham station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Bossingham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
