Guston: your questions answered
Do you work for landlords with property near Martin Mill station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is Guston in your area for new build mastic?
Yes, Guston is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items and we will give you a quote. We will flag anything that needs another trade.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
New build mastic in Guston, done properly
We work in new homes and on new-build sites across Guston. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Typical jobs include worktop and upstand sealant coming away and beads laid onto grit and dust from the build, across show homes, kitchens and skirting & floors.
In a village or hamlet like Guston, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Big or small, it’s backed by our 12-month guarantee in Guston and across Kent.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Watch for new gaps as the house dries out
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Keep pictures and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
Joints and finishes in Guston homes
Guston 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Martin Mill station, it’s worth checking the sealant early, while snags are still fresh.

What affects the quote in Guston
There’s no set price list, because jobs vary so much. The quote depends on:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Access and height
- The size of the job
The cost depends on how much there is to do, 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 we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- Any access issues, like height or stairs
- If someone has resealed it before
- A few pictures by email, if you can
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Guston, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before work begins.
- 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.
Before we arrive
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Advice
Why deal with it now?
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. Around Guston, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
