About our new build mastic in Little Coxwell
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you’re dealing with plot mastic for developers ahead of handover and leaking shower tray seals in a new home, we can help, on plot handovers, skirting & floors and windows & doors alike.
In a village or hamlet like Little Coxwell, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Little Coxwell: your questions answered
Is there a guarantee on new build mastic in Little Coxwell?
All our work, in Little Coxwell and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do new build mastic in Little Coxwell?
Yes, Little Coxwell is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room before we begin.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Little Coxwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 doesn’t work out, we can still put it right.
What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- The product the joint needs
- The number and length of the joints
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Whether it’s a home or a business
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. For a village or hamlet like Little Coxwell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Do you need new build mastic in Little Coxwell?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Any of these means the joints need attention:
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
Around Little Coxwell, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Aftercare is simple:
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Don’t seal over failed sealant yourself
- Put sealant faults on your snagging list early
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
