How we handle new build mastic in Dover
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We’re often asked to deal with cracks appearing as a new home settles and frame joints opening as the plaster dries, on windows & doors, show homes and skirting & floors.
Homes around Dover move a little with the seasons, and skirting and floor joints show it first. A flexible sealant, rather than rigid filler, keeps those joints closed.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.
Joints and finishes in Dover homes
Dover is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, 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 Dover Priory station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Dover, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. In a family home in Dover, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

- If someone has resealed it before
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Pictures of the joints, sent by email

Dover: your questions answered
Is new build mastic in Dover guaranteed?
All our work, in Dover and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Dover Priory station?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Why does sealant fail so quickly in new builds?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours in a single home for a typical job. Parking in a town like Dover is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Get a leaking seal dealt with right away
- Look at the sealant regularly in the first couple of years
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
