New build mastic in Bayworth
We work in new homes and on new-build sites across Bayworth. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, plot handovers and skirting & floors, and people most often call us about internal frame sealant that has split and gaps opening as the house dries out and settles.
Older homes in small places like Bayworth often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- The number of rooms or windows
- Any working-time requirements on site
- How easy the joints are to reach
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear price before we start.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
To get a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Where a wall is exposed, as many are in small places like Bayworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Your warranty claim itself, which is between you and the builder
- A tray or bath that is not properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

What else we do in Bayworth
New build mastic around Bayworth
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Radley station, the sealant around baths, showers and frames is worth checking in the first year or two.

It’s worth asking for a quote if you see:
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
In and around Bayworth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Bayworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Tell us if parking is tricky

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
- Record problems with dated photos
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
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 the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
