New build mastic in North Warnborough, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have joints pulling apart as timber shrinks and untidy sealant flagged on a snagging list, we can put it right, whatever the surface.
Older homes in small places like North Warnborough often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Put sealant faults on your snagging list early
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Don’t wait for the house to settle if water is getting through
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.

How long does new build mastic take?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. Somewhere like North Warnborough needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Related advice
DIY sealant or a professional job?
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 does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around North Warnborough, older homes often have timber in their floors and frames, and water through a failed joint can rot timber 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. Your quote takes all of that into account.

Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
When to call us in North Warnborough
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
For new homes near Hook station, it’s worth checking the sealant early, while snags are still fresh.
