Signs you need new build mastic in Purbrook Heath
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry.
These are the problems we’re asked about most:
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
If you’ve bought a new home near Cosham station, the sealant around baths, showers and frames is worth checking in the first year or two.

About our new build mastic in Purbrook Heath
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have messy sealant that spoils new finishes and internal frame sealant that has split, we can help.
In a village or hamlet like Purbrook Heath, 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.
There’s a 12-month guarantee on every job.

Why it’s worth doing now in Purbrook Heath
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Purbrook Heath, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Colour picked to suit the job
- Experience in homes, commercial sites and hotels
- We’re fully insured
- We leave the area clean and tidy

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.

Where is Mr Mastic based?

Is it normal for sealant to crack in a new home?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
