New build mastic for homes and businesses in Hoo St Werburgh
Across Hoo St Werburgh, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on plot handovers, bathrooms & en suites and windows & doors, and common reasons people get in touch are gaps opening as the house dries out and settles and frame joints opening as the plaster dries.
If you’ve bought a new home in or near Hoo St Werburgh, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a 12-month guarantee, the same in Hoo St Werburgh as everywhere else we work.

New build mastic around Hoo St Werburgh
Hoo St Werburgh is close to 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.
If you’ve bought a new home near Gillingham (Kent) station, the sealant around baths, showers and frames is worth checking in the first year or two.

Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Access and height
- The number of rooms or windows
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- Pictures of the joints, sent by email
- The problem you’ve noticed
- How many joints, rooms or windows are involved
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots for a typical job. In a smaller place like Hoo St Werburgh, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you need new build mastic in Hoo St Werburgh?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Common reasons people contact us include:
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
Around Hoo St Werburgh, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- What guarantee comes with the work
- Whether they seal over old material or remove it
- Whether you can choose the colour
- What happens if the job turns out different
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Looking after it afterwards
So the new joints stay in good condition:
- Record problems with dated photos
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
- Do not wait for the house to settle if water is getting through
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
