What we’re called out for in Flackley Ash

Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.

Signs it’s time to call us include:

  • Sealant that never bonded to the surface
  • Leaking shower tray seals in a new home
  • Cracked caulk along new skirting
  • Smeared, uneven beads picked up at snagging

For new homes near Rye station, it’s worth checking the sealant early, while snags are still fresh.

About our new build mastic in Flackley Ash

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you’re dealing with skirting joints opening in the first winter and worktop and upstand sealant coming away, we can put it right, whatever the surface.

Somewhere as small as Flackley Ash, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.

We stand behind the work with a 12-month guarantee.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Watch for new gaps as the house dries out
  • Wait for the cure time before using a resealed shower
  • Get a leaking seal dealt with right away
  • Resist patching a failed seal with a tube from the DIY shop

Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

For landlords and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Landlords and agents in Flackley Ash can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

FAQs for Flackley Ash

Is Flackley Ash within the area you cover?

Yes, Flackley Ash is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Yes, Flackley Ash is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.

Can I add another job to the visit?

Do you remove the old sealant?

Do you take on second-fix sealing for builders?

Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved for a clear quote.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

When is the sealant fully cured?

That depends on the sealant used, so please follow the time we give you.

Honest limits

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Deciding who is responsible under a builder’s warranty
  • Settlement cracks that need a surveyor
  • Baths and trays that move too much for sealant to cope with

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

What happens if it’s left?

For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a small place like Flackley Ash, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why book with us

  • Every job guaranteed for a year
  • Colour picked to suit the job
  • Fully insured
  • Any old sealant cut out fully, not covered over

How it works

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Flackley Ash, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • For indoor joints, keep the area dry beforehand if you can
