New build mastic in Northbourne
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have skirting joints opening in the first winter and messy sealant that spoils new finishes, we can put it right, on kitchens, skirting & floors and bathrooms & en suites alike.
Around Northbourne, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, in Northbourne and everywhere else we cover.

Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.

What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- The number of rooms or windows
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Where the property is
- Any previous sealing or DIY work
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
When to call us in Northbourne
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
The most common problems we see are:
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
For new homes near Walmer station, it’s worth checking the sealant early, while snags are still fresh.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What happens on the day
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours in a single home, and we tell you how long to leave it before we go. For a village or hamlet like Northbourne, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

Advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Aftercare tips
After the cure time, these simple habits help:
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
- Do not seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
