- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Look at the sealant regularly in the first couple of years
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
New build mastic in Keeres Green
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you are dealing with shower seals failing in the first year or two and beads laid onto grit and dust from the build, we can help, on kitchens, show homes and bathrooms & en suites alike.
Somewhere as small as Keeres 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.
All our work is covered by our 12-month guarantee.

What affects the cost of new build mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Access and height
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Questions from Keeres Green
What guarantee comes with new build mastic in Keeres Green?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Will you come out to Keeres Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
DIY versus a professional finish
If you are set on DIY, put the effort into 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.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Signs you need new build mastic in Keeres Green
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
It’s worth asking for a quote if you see:
- Cracked caulk along new skirting
- Second-fix sealing on new plots
- Messy sealant that spoils new finishes
- Kitchen sealant that has pulled off the wall
In and around Keeres Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

The process
Once we’re on site, 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. In a small place like Keeres Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- 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.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Mention if the joints have been sealed before
