About our new build mastic in Hornton
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on windows & doors, bathrooms & en suites and show homes, and common reasons people get in touch are untidy sealant flagged on a snagging list and leaking shower tray seals in a new home.
Somewhere as small as Hornton, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. Somewhere like Hornton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before

Advice
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Don’t wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. Tell us when the home is open so we can plan around it.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Hornton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- The product the joint needs
- How much there is to do
- How many areas need sealing
- How easy the joints are to reach
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- Where the property is
- The problem you’ve noticed
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
Can I do it myself?
If you are set on DIY, put the effort into 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracking that points to a structural problem
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
