New build mastic in Canvey Island
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first. If you have untidy sealant flagged on a snagging list and kitchen sealant that has pulled off the wall, we can help.
In a town like Canvey Island, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We’ll plan around viewing times.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Your questions about new build mastic in Canvey Island
Is Canvey Island in your area for new build mastic?
Yes, Canvey Island is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is new build mastic in Canvey Island guaranteed?
All our work, in Canvey Island and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Is it normal for sealant to crack in a new home?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved for a clear quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- Whether the work is at height
- The type of sealant required
- How much there is to do
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Helping us quote
When you contact us, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Any previous sealing or DIY work
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.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

Do you need new build mastic in Canvey Island?
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, and sealant that can’t keep up splits.
Look out for these signs:
- Cracked caulk along new skirting
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
For new homes near Benfleet station, it’s worth checking the sealant early, while snags are still fresh.

What new build mastic looks like in Canvey Island
Canvey Island is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Canvey Island, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most snagging lists, longer for a run of plots. Parking in a town like Canvey Island is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- 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 if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
