New-build mastic & snagging in Smannell, Hampshire
We cover Smannell for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.

Should I try it myself first?
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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
About our new build mastic in Smannell
Across Smannell, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you’re dealing with leaking shower tray seals in a new home and beads laid onto grit and dust from the build, we can help, whatever the surface.
Around Smannell, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours in a single home. Somewhere as small as Smannell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
Getting a quote
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clean sealant with mild detergent, not abrasives
- Keep pictures and emails about snagging items
- Don’t wait for the house to settle if water is getting through
- Use the extractor fan every time you shower
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Plumbing faults behind the sealant
- A tray or bath that is not properly supported, until it’s fixed
- Structural cracks in walls or ceilings
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there.
