About our new build mastic in Silverhill
Across Silverhill, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. Common call-outs are for messy sealant that spoils new finishes and cracks appearing as a new home settles, on bathrooms & en suites, kitchens and windows & doors.
If you’ve bought a new home in or near Silverhill, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
There’s a 12-month guarantee on every job.

Your questions about new build mastic in Silverhill
Do you cover smaller places like Silverhill?
Yes. Silverhill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near St Leonards Warrior Square station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do you use white or clear sealant?
White and clear are the most common, but other colours are available. We choose one to suit the room and agree it with you.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home, including the tidy-up. Parking around Silverhill is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Tell us about any water getting in

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details.

What new build mastic looks like in Silverhill
Silverhill is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Silverhill, as everywhere, new build mastic is only as good as the preparation behind it.

What else we do in Silverhill
What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Access and height
- Working hours on commercial sites
- The amount of work
- How many areas need sealing
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- Whether it’s a home or a business
- Any previous sealing or DIY work
- A few photos by email, if you can
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Broken tiles or a split tray
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.
