About our new build mastic in Little Marlow
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. We work on show homes, kitchens and skirting & floors, and the jobs we see most are new-build shower sealant that has already split and frame joints opening as the plaster dries.
For a small place like Little Marlow, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What new build mastic looks like in Little Marlow
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Little Marlow is about 2 miles north-east of Marlow, in Buckinghamshire. From the centre of Little Marlow to the outskirts, new build mastic is available for homes and businesses alike.

Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We will plan around viewing times.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. For a village or hamlet like Little Marlow, 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- 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
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Little Marlow questions
I let a flat near Bourne End station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can you do new build mastic in Little Marlow?
Yes, Little Marlow is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Deciding who is responsible under a builder’s warranty
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracking that points to a structural problem
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Skirting & floors
- Bathrooms & en suites
- Windows & doors
- Kitchens
- Show homes
- Plot handovers
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Act quickly if a seal starts to leak
- Keep photos and emails about snagging items
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
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.
Common problems we fix in Little Marlow
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
It’s worth asking for a quote if you see:
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
- Internal frame sealant that has split
If you’ve bought a new home near Bourne End station, the sealant around baths, showers and frames is worth checking in the first year or two.
