New build mastic for homes and businesses in Nob's Crook
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you are dealing with smeared, uneven beads picked up at snagging and sealant that never bonded to the surface, we can help, on kitchens, show homes and windows & doors alike.
Older homes in small places like Nob's Crook often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with a 12-month guarantee.

What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.

Yes. We cut out all the old sealant and clean the joint before resealing.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

When to call us in Nob's Crook

- Shower seals failing in the first year or two
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
For new homes near Eastleigh station, it’s worth checking the sealant early, while snags are still fresh.

What else we do in Nob's Crook
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Nob's Crook, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Advice
What the job involves on each surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Nob's Crook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why book with us
- Full insurance on every job
- Any old sealant cut out fully, not covered over
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Do not seal over failed sealant yourself
- Wipe joints with warm soapy water
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
