New build mastic for homes and businesses in Hatchet Green
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on kitchens, show homes and windows & doors, and common reasons people get in touch are internal frame sealant that has split and shower seals failing in the first year or two.
Somewhere as small as Hatchet Green, 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.
There’s a 12-month guarantee on every job, large or small.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Aftercare tips
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
How the job changes by surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
What new build mastic looks like in Hatchet Green
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.
In and around Hatchet Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Hatchet Green, choosing the right material for each joint is as important as a tidy finish.

How we quote for new build mastic

- Mould in or behind the old joints
- When we can work, for business premises
- How easy the joints are to reach
- How many rooms, windows or areas are involved
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
For new build mastic in Hatchet Green, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- 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.
