New build mastic for homes and businesses in Chestfield
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. We work on show homes, bathrooms & en suites and kitchens, and the jobs we see most are shower seals failing in the first year or two and cracked sealant around new window and door frames.
Somewhere as small as Chestfield, 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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Chestfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home and we leave things clean and tidy. Somewhere like Chestfield needs a little journey planning: 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.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- 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
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
