What affects the cost of new build mastic
You’ll get a clear quote before work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Access and height
- Any mould that needs treating
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.
What to tell us 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 is easy
- What’s wrong with the joints now
- How we’d reach the joints
- Any previous sealing or DIY work
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
New build mastic in Clayhill, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We are often asked to deal with smeared, uneven beads picked up at snagging and skirting joints opening in the first winter, on skirting & floors, show homes and plot handovers.
For a small place like Clayhill, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, in Clayhill and everywhere else we cover.

How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
What new build mastic looks like in Clayhill
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.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Broken tiles or a split tray
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Joints and surfaces we work on

Landlord and commercial work in Clayhill
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Questions from Clayhill
Do you cover Clayhill for new build mastic?
Yes, Clayhill is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Is Clayhill within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
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.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
When to call us in Clayhill
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Look out for any of the following:
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
If you’ve bought a new home near High Wycombe station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How the joint is cleaned and prepared
- How hidden problems are handled
- Whether they seal over old material or remove it
- Whether VAT is included
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Clayhill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
