After the work

Keep the joints in good shape with a few simple steps:

  • Act on the first lifting edges rather than waiting
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Keep barriers up until the new sealant has cured

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface. We work on external facade joints, floor and threshold joints and kitchen worktops and splashbacks, and the failures we are asked to look at most are a top-up bead over failed sealant, now lifting and sanitary sealant that has gone black and patchy. A single leaking joint is often how a building in Groombridge first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Occupied buildings in Groombridge need the work phased: we agree the order with you and hand back each area with its cure time.

Business units in the countryside around places like Groombridge are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Roof leaks that only look like a joint problem
  • Water from a services leak rather than a joint
  • Misted, cracked or failed glazing units (a glazier’s job)

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

Where we work in Groombridge

  • Floor and threshold joints
  • External facade joints
  • Kitchen worktops and splashbacks
  • Washrooms and tea points
  • Movement joints in walls and floors
  • Window and door perimeters

Working on commercial sites near Groombridge

The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. At about 29 miles from central London, Groombridge is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

On a business park such as Speldhurst Business Park, 2.7 miles north-east of Groombridge, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Offices and shops close to stations such as Eridge station (1.8 miles south-east of Groombridge) tend to be busy all day, so sealant work is planned around opening hours.

Groombridge is about 4 miles south-west of Royal Tunbridge Wells, in East Sussex. Businesses, contractors and managing agents in Groombridge can call on us for sealant joints, as part of our coverage of East Sussex. We work across 308 places in East Sussex, from busy centres to rural villages. There’s a separate page for Brighton, about 24 miles away.

Business premises anywhere in TN3 are within our area. Streets here include Station Road, Meadow Road and Orchard Rise, and sites on any of them can send details for a fixed quote. We also cover Birchden (1 mile south-east), Stone Cross (1 mile north), Ashurst (2 miles north-west), Balls Green (2 miles west) and Fordcombe (2 miles north) for sealant joints. A short drive away, we cover Crowborough (4 miles south), Uckfield (11 miles south), Heathfield (11 miles south), Wadhurst (7 miles south-east), Ridgewood (11 miles south) and Sandy Cross (11 miles south).

How the quote is worked out

These are the things that shape the price:

  • Location, for remote and island sites
  • The total length or number of joints
  • Access and working height
  • Working within restricted access windows

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • The product your specification calls for
  • The postcode of the building
  • Your programme or deadline
  • Access details, including height

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Groombridge can form part of a wider programme.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

What happens if it’s left?

Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Dealing with it while the damage stops at the bead is the cheaper route. Older rural buildings around Groombridge move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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

Questions we are asked in Groombridge

Can you match sealant colours for premises in Groombridge?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we’ll confirm what’s available for the product.

Does your area include sites such as Speldhurst Business Park, near Groombridge?

Yes. Our area takes in Groombridge and its surroundings, with estates and business parks such as Speldhurst Business Park included. Photos and a short description are enough for a first look.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.
