About our commercial sealant contractors in Lidsey

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind. Part of the job is telling you when the fix is something other than sealant, so nobody pays for a reseal that can’t hold. If you’re dealing with shrunken sealant along kitchen worktops and splashbacks and wall and floor joints that have lost their seal, we can help, on external facade joints, kitchen worktops and splashbacks and window and door perimeters alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lidsey, that means joint design, primers and backing rod as standard.

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

In and around smaller places such as Lidsey, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email us and we’ll arrange a return visit.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks, and our waste is bagged and taken away as we go. Smaller jobs around Lidsey can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings

Maintenance after handover

After handover, a little attention goes a long way:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Look at the sealant around anything that has been moved or replaced
  • Keep barriers up until the new sealant has cured
  • Keep a record of which joints were resealed and when

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks. If anything looks wrong, phone 01277 525 020 or send details through our quote form with a photo.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.

What the job involves on each surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Signs you need commercial sealant contractors in Lidsey

When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

Common reasons buildings call us in:

  • A top-up bead over failed sealant, now lifting
  • Black mould through washroom sealant that won’t clean off
  • Gaps behind commercial kitchen worktops and sinks
  • Window and door perimeter joints that have cracked open

For tenants and agents on sites such as Saltbox Business Park., 0.9 miles south of Lidsey, office fit-outs, reception joints and window perimeters are the usual sealant work.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Are they CHAS accredited or on Constructionline?
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Why deal with it now?

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. Resealing typically costs far less than renewal. Older rural buildings around Lidsey move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Frontages, fit-outs and joints in Lidsey

Lidsey is within about 3 miles of the coast. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Where a frontage needs a particular colour, the product still has to suit that exposure. Rainfall across the South East, Lidsey included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Barnham station, which lies north-east of Lidsey, footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at Saltbox Business Park. And Southern Cross Trading Estate, one contractor and one quote can cover both.
