What new build mastic looks like in Stock
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.
If you’ve bought a new home near Billericay station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Stock, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. Common call-outs are for messy sealant that spoils new finishes and sealant work across a run of new homes, across show homes, plot handovers and skirting & floors.
Around Stock, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How the visit works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work usually takes anything from a few hours to several days, depending on the number of plots. Somewhere like Stock needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

How to get a quote
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or email us.
Advice
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Stock: your questions answered
Do you work for landlords with property near Billericay station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Stock?
Yes, Stock is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can. We’ll flag anything that needs another trade.
Common problems we fix in Stock
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The problems people usually mention when they call include:
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
In and around Stock, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Asking for a quote
To help us quote quickly, let us know:
- The rough size of the job
- The type of property
- Whether it has been sealed before
- The problem you’ve noticed
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
- Report sealant problems to your builder during the snagging period
- Keep pictures and emails about snagging items
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Landlord and commercial work in Stock
Landlords and letting agents in Stock can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
