About our new build mastic in Golden Green
We work in new homes and on new-build sites across Golden Green. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you are dealing with gaps opening as the house dries out and settles and gaps behind new kitchen upstands, we can put it right, on kitchens, plot handovers and show homes alike.
Around Golden Green, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work is covered by a one-year guarantee.

Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Golden Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

In and around Golden Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Beltring station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours in a single home, depending on the amount of work. Somewhere as small as Golden Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- 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.
Before we arrive
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
How to get a quote

Advice
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- The number of rooms or windows
- The type of sealant required
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
When you call or email, these details help:
- Photos by email, if that’s easy
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- How we’d reach the joints
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work.
Landlords, agents and businesses in Golden Green
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
When something else is needed
New sealant cannot fix everything, and we will tell you before we start. Sealant won’t put right:
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

FAQs for Golden Green
Do you work for landlords with property near Beltring station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Golden Green?
Yes, Golden Green is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we will say how long yours will take.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
