New build mastic in Hardley, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for second-fix sealing on new plots and internal frame sealant that has split, across plot handovers, kitchens and windows & doors.
Somewhere as small as Hardley, 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.
Your job is guaranteed for a year, as with all our work.

What the job involves on each 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.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a small place like Hardley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

FAQs for Hardley
Can you help a landlord with a rental near Netley station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Is Hardley in your area for new build mastic?
Yes. We work across London and the South East, and Hardley is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Are you fully insured?
Yes, we are fully insured.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Broken tiles or a split tray
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. In a small place like Hardley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Follow the cure time we give you
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
New homes and floors in Hardley
Hardley is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Hardley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Netley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
