About our new build mastic in Hinxworth
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. We work on bathrooms & en suites, skirting & floors and plot handovers, and people most often call us about kitchen sealant that has pulled off the wall and messy sealant that spoils new finishes.
Somewhere as small as Hinxworth, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You get a one-year guarantee, the same in Hinxworth as everywhere else we work.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. For a village or hamlet like Hinxworth, 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 start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
New homes and floors in Hinxworth
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.
In and around Hinxworth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few photos. Where a wall is exposed, as many are in small places like Hinxworth, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Hinxworth: your questions answered
Can you do new build mastic in Hinxworth?
Yes, Hinxworth is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Arlesey station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
What we’re called out for in Hinxworth
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Look out for these signs:
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
If you’ve bought a new home near Arlesey station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Whether VAT is included
- What preparation is included
- Who does the work, and how experienced they are
- The length of the guarantee
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Get a leaking seal dealt with right away
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
