New build mastic in Green Street Green, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on skirting & floors, show homes and plot handovers, and common reasons people get in touch are sealant applied over dusty or wet surfaces and internal frame sealant that has split.
For a small place like Green Street Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Do you need new build mastic in Green Street Green?
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
It’s worth asking for a quote if you see:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
Around Green Street Green, as everywhere, new build mastic is only as good as the preparation behind it.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Can I do it myself?
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 fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you fully insured?
Yes. Full insurance covers our work.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we’ll do.
Aftercare tips
Looking after new joints is easy:
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
