New build mastic for homes and businesses in Fullerton
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you have gaps behind new kitchen upstands and internal frame sealant that has split, we can put it right, whatever the surface.
Older homes in small places like Fullerton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

What else we do in Fullerton
How to look after the new joints
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
FAQs for Fullerton
Will you come out to Fullerton?
Yes. Fullerton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Andover station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we will quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Are you fully insured?
Yes. We’re fully insured.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
New build mastic in Fullerton: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Andover station, the sealant around baths, showers and frames is worth checking in the first year or two.

What affects the cost of new build mastic
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- The old material and how stubborn it is
- Whether the work is at height
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details, and pictures are welcome.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home. Somewhere as small as Fullerton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

Related advice
What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Common problems we fix in Fullerton
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
People normally contact us after spotting one of these:
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
In and around Fullerton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
