New build mastic for homes and businesses in Marlpit Hill
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, windows & doors and bathrooms & en suites, and the jobs we see most are frame joints opening as the plaster dries and shower seals failing in the first year or two.
Older homes in small places like Marlpit Hill often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a one-year guarantee, the same in Marlpit Hill as everywhere else we work.

How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The size of the job
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- Pictures of the joints, sent by email
- The address or postcode of the job
- How we’d reach the joints
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Marlpit Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Advice
Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors as agreed.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Do you need new build mastic in Marlpit Hill?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
The problems people usually mention when they call include:
- New-build shower sealant that has already split
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Edenbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How hidden problems are handled
- Is VAT in the price?
- Which sealant they’ll use, and why
- What the cure time is
What we can’t put right
To be straight with you, some problems need a different trade:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
