How we handle commercial sealant contractors in Old Shoreham

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, matching the sealant to the location instead of using one product throughout. If you have frame mastic that has hardened and come away from the wall and weathered facade sealant that no longer flexes, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Old Shoreham, preparation and product choice get the time they need.

Quotes for commercial sealant in Old Shoreham can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

Commercial sealant work around smaller places like Old Shoreham tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

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.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Keep barriers up until the new sealant has cured
  • Note dates and locations of sealant work for future planning
  • Make sure ventilation in wet areas is switched on and working
  • Put external and wet-area joints on a regular inspection round

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

Sealant installed at the same time typically fails in sequence. A few splits this year normally mean more next year. We can assess the lot and suggest what to do now and later.

What we’re called out for in Old Shoreham

Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade all let go sooner than they should. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

Things that usually lead to an enquiry:

  • Earlier reseals applied straight onto the failed bead
  • Gaps behind commercial kitchen worktops and sinks
  • Water staining near frames, panels or ceilings
  • Hardened, chalky sealant on south-facing or exposed elevations

Sites a few miles apart, such as Dolphin Industrial Estate and Grange Industrial Estate, can share one programme and one point of contact.

Comparing quotes

  • Are they CHAS accredited or on Constructionline?
  • The named product and why it was chosen
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid

Questions about Old Shoreham

Is a smaller place like Old Shoreham outside your area?

Not at all: smaller places are covered as well as towns. 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.

Is Dolphin Industrial Estate, near Old Shoreham, within your area?

Yes, sites like Dolphin Industrial Estate are within our area, along with the rest of Old Shoreham. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is the old sealant taken out first?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.

Do you work directly for building managers?

Yes. You can send details through our quote form.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Old Shoreham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
  • Let building users know which areas are affected

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email the details over.

Advice

Leave it or put it right?

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation. Older rural buildings around Old Shoreham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Why us?

  • CHAS accredited contractor
  • Old sealant cut out, never sealed over
  • Colours confirmed for the specified product
  • Fully insured, including public liability cover

See our cost guide or our accreditations.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Structural cracks or movement the joints weren’t designed for
  • Broken glass or blown double-glazed units

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think.

Joints and surfaces we work on

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

Shops, offices and hotels in and around Old Shoreham

Old Shoreham sits close to the coast, within about 1 mile. 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. Less than 3 miles from Old Shoreham there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

For premises near Shoreham-By-Sea station, 0.7 miles to the east of Old Shoreham, footfall is part of the plan: work is phased so shops and offices keep trading. Industrial estates such as Dolphin Industrial Estate, 1.4 miles east of Old Shoreham, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

What the job involves on each surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.

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.
