How we handle new build mastic in Eling
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on bathrooms & en suites, windows & doors and show homes, and people most often call us about leaking shower tray seals in a new home and smeared, uneven beads picked up at snagging.
Where new homes go up in smaller places like Eling, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Questions from Eling
I let a flat near Totton station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Eling?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items. We’ll tell you if anything on it is not a sealant job.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Eling and the rest of Southampton, along with the rest of our area.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. If it isn’t resolved, we’ll cut it out and reseal it.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
When to call us in Eling
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
For new homes near Totton station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether all the old sealant comes out first
- Which colour the sealant will be
- Who turns up on the day

What new build mastic looks like in Eling
Eling is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Eling, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
How it works
When we get to you, 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. For a job in Eling, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Cracking that points to a structural problem
- Damaged fittings that need replacing
- A tray or bath that isn’t properly supported, until it’s fixed
