Sealant specialists in Five Ash Down

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike. We work on kitchen worktops and splashbacks, washrooms and tea points and window and door perimeters, and what we’re called in for most is external beads that have gone brittle and cracked and greasy, split joints in a kitchen or tea point. Whoever orders the work in Five Ash Down, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

A lot of what we do in Five Ash Down is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Rural business units near smaller places such as Five Ash Down are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • A dripping trap, valve or pipe behind a fitting
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Walls or slabs moving more than any sealant can take

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

  • Kitchen worktops and splashbacks

Cost factors for sealant joints

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether the work must be split into stages
  • Which sealant the job calls for
  • The total length or number of joints
  • Any access equipment needed

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email a schedule or drawings.

Why it’s worth doing now in Five Ash Down

Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Around Five Ash Down, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Will you take on work at estates like Ashdown Business Park, close to Five Ash Down?

Is Five Ash Down too small for you to travel to?

No. Places such as Five Ash Down are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Does commercial sealant work come with a guarantee?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Maintenance after handover

Once the work is signed off, these steps help:

  • Have extract fans checked so wet areas dry out
  • Check joints after other trades have worked nearby
  • Keep abrasive pads and scrapers off resealed joints
  • On pre-2000 buildings, share the asbestos information before work starts

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just phone 01277 525 020 or email the details over for a quote.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
