Commercial sealant contractors in Fontwell, done properly

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). If you are dealing with expansion joints with the sealant torn out and frame sealant that has cracked, shrunk or pulled away, we can put it right, on external facade joints, movement joints in walls and floors and washrooms and tea points alike. Whoever orders the work in Fontwell, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

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

A job in a smaller place like Fontwell is normally a single building. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Signs you need commercial sealant contractors in Fontwell

In wet areas the enemy is usually mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. The fix is a new bead of anti-mould sanitary silicone.

These are often picked up first by site or facilities staff:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Gaps behind commercial kitchen worktops and sinks
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Layers of sealant, all of them failing

On estates like Tokar Industrial Park (1.8 miles south-east of Fontwell), the office and welfare end of each unit has its own sealant to maintain.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Their public liability cover
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

Common questions from Fontwell clients

Does a hotel in Fontwell need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Is Fontwell off your patch?

Not at all. Fontwell is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can one contractor look after sealant on all our buildings?

Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.

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 checks let you plan resealing before leaks or damage.

Is it OK to apply fresh sealant over existing beads?

Full removal is part of every quote. A bead laid on old silicone peels away, so it isn’t something we do.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Suspect materials that need testing and specialist removal
  • Structural cracks or movement the joints weren’t designed for
  • Faulty windows rather than failed perimeter sealant

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

Surfaces we seal

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

Maintenance after handover

After handover, a little attention goes a long way:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Act on the first lifting edges rather than waiting
  • Check sealant as part of routine building inspections
  • Ask cleaners to use a soft cloth and mild cleaner on sealant

In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.

Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Commercial sealant contractors in Fontwell: the local picture

Fontwell has at least three named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen. Several hotels sit less than 2 miles from Fontwell. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.

A business with units at Tokar Industrial Park and Sussex Business Village needn’t use two contractors for its sealant. Shops and cafés around stations like Barnham station, 1.6 miles south of Fontwell, trade from early, so work is timed around them.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a few hours for one area, or a planned series of visits across a bigger building. For work around Fontwell, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need
  • Move anything stored against the joints

Should maintenance staff do it?

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Joint width, depth and condition
  • Distance, for remote addresses
  • The product specified
  • Site requirements such as inductions and permits

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • The product your specification calls for

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email drawings and photos.
