About our new build mastic in Green Tye
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on skirting & floors, show homes and windows & doors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and sealant work across a run of new homes.
Older homes in small places like Green Tye often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a small place like Green Tye, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Questions from Green Tye
Is Green Tye in your area for new build mastic?
Yes. We work across London and the South East, and Green Tye is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Bishops Stortford station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items. We’ll flag anything that needs another trade.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before work begins. It will not solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
What we seal
- Kitchens
- Plot handovers
- Skirting & floors
- Windows & doors
- Show homes
- Bathrooms & en suites
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Clean sealant with mild detergent, not abrasives
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Early snagging is easier snagging. Small faults turn into leaks if left over time.

Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- A few pictures by email, if you can
- If someone has resealed it before
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots from start to finish. Somewhere like Green Tye needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Do you need new build mastic in Green Tye?
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
The problems people usually mention when they call include:
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
In and around Green Tye, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
