How we handle new build mastic in Beckley Furnace
Across Beckley Furnace, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on kitchens, windows & doors and skirting & floors, and common reasons people get in touch are gaps behind new kitchen upstands and joints pulling apart as timber shrinks.
In a village or hamlet like Beckley Furnace, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
A one-year guarantee comes as standard.

Aftercare tips
To keep the joints looking good and working properly:
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Keep pictures and emails about snagging items
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Questions from Beckley Furnace
Is Beckley Furnace in your area for new build mastic?
Yes, Beckley Furnace is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Can you help a landlord with a rental near Doleham station?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items, and we’ll quote. We will tell you if anything on it is not a sealant job.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours in a single home. We will tell you when we quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Bathrooms & en suites
- Skirting & floors
- Plot handovers
- Kitchens
- Show homes
- Windows & doors
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Where a wall is exposed, as many are in small places like Beckley Furnace, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Quotes for new build mastic in Beckley Furnace
We quote each job individually. This is what makes a difference:
- Working hours on commercial sites
- The size of the job
- Whether the work is at height
- Any mould that needs treating

What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Beckley Furnace, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Mention if the joints have been sealed before
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

What we are called out for in Beckley Furnace

Any of these means the joints need attention:
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
If you’ve bought a new home near Doleham station, the sealant around baths, showers and frames is worth checking in the first year or two.
