New build mastic for homes and businesses in Kilnwood Vale
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on bathrooms & en suites, kitchens and plot handovers, and common reasons people get in touch are sealant work across a run of new homes and internal frame sealant that has split.
Work in a small place like Kilnwood Vale just needs the journey and access planning, and the work itself is the same as on any site.
Big or small, it’s backed by our 12-month guarantee.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- Which sealant suits the joint
- The number of rooms or windows
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- Roughly how big the job is
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What we’re called out for in Kilnwood Vale
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Any of these means the joints need attention:
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
For new homes near Faygate station, it’s worth checking the sealant early, while snags are still fresh.
Comparing quotes
- Who does the work, and how experienced they are
- Which colour the sealant will be
- Whether they’re fully insured
- Whether all the old sealant comes out first
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a small place like Kilnwood Vale, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Disputes or warranty claims with your builder
- Broken tiles or a split tray
- A tray or bath that is not properly supported, until it’s fixed
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Kilnwood Vale questions
Can you do new build mastic in Kilnwood Vale?
Yes, Kilnwood Vale is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can you help a landlord with a rental near Faygate station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Kilnwood Vale, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or another colour, product permitting
- Homes, businesses and hotels
- An ARBOMaster approved applicator
