About our new build mastic in Asheridge
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have internal frame sealant that has split and shower seals failing in the first year or two, we can put it right, whatever the surface.
In a village or hamlet like Asheridge, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Asheridge questions
Can you do new build mastic in Asheridge?
Yes. We work across London and the South East, and Asheridge is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Great Missenden station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you use white or clear sealant?
White and clear are the most common, but other colours are available. We choose one to suit the room.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items and we will give you a quote. We will flag anything that needs another trade.
How long does new build mastic take?
It depends on the size of the job, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Asheridge, 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, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

What the job involves on each 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.
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Around Asheridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When it isn’t the sealant
It helps to know what we can’t do too:
- Settlement cracks that need a surveyor
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Skirting & floors
- Bathrooms & en suites

What we’re called out for in Asheridge
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
These are the problems we are asked about most:
- Internal frame sealant that has split
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
Around Asheridge, as everywhere, new build mastic is only as good as the preparation behind it.
