About our new build mastic in Larkfield
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for frame joints opening as the plaster dries and leaking shower tray seals in a new home, across bathrooms & en suites, kitchens and skirting & floors.
In a village or hamlet like Larkfield, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. For a village or hamlet like Larkfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Can I do it myself?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How we quote for new build mastic
We do not publish a price list. What we look at:
- The old material and how stubborn it is
- Any working-time requirements on site
- The number of rooms or windows
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Where the job is, and your postcode
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or email us.
Common questions in Larkfield
Do you cover smaller places like Larkfield?
Yes. Larkfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near New Hythe station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does new build mastic take?
Most jobs take a few hours in a single home. Your quote will say how long we expect yours to take.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Where a wall is exposed, as many are in small places like Larkfield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

When to call us in Larkfield
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The problems people usually mention when they call include:
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
For new homes near New Hythe station, it’s worth checking the sealant early, while snags are still fresh.

Aftercare tips
Looking after new joints is easy:
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
