Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How we handle new build mastic in Flemings
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have second-fix sealing on new plots and smeared, uneven beads picked up at snagging, we can put it right, on kitchens, bathrooms & en suites and windows & doors alike.
For a small place like Flemings, the journey and access are planned in advance, and the work itself is the same as on any site.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
What new build mastic looks like in Flemings
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Flemings
Is Flemings in your area for new build mastic?
Yes. We work across London and the South East, and Flemings is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Sandwich station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
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.
Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Why has my new-build shower seal failed already?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

What else we do in Flemings
Signs you need new build mastic in Flemings
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
- Sealant that never bonded to the surface
- Shower seals failing in the first year or two
Around Flemings, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- How the joint is cleaned and prepared
- Whether VAT is included
- Which sealant they’ll use, and why
- When the joint can take water or movement
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Flemings, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Advice
Why it’s worth doing now in Flemings
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Around Flemings, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
