Commercial sealant contractors in East Lavant, done properly

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Most enquiries involve gaps behind commercial kitchen worktops and sinks and messy, uneven beads from earlier work that let the building down, across washrooms and tea points, window and door perimeters and external facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in East Lavant it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

If you look after more than one building near East Lavant, the work can be planned as one programme, so standards and paperwork match across every site.

Commercial sealant work around smaller places like East Lavant tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Our workmanship is guaranteed for 12 months, in East Lavant as everywhere else we work. If our installation lets you down in that time, we return and fix it.

After the work

To get the most from the new sealant:

  • Check sealant as part of routine building inspections
  • Don’t let cleaning or traffic back on before the cure time is up
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Act on the first lifting edges rather than waiting

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks. If anything looks wrong, call the office on 01277 525 020 or send photos by email with a photo.

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.

Questions about East Lavant

Will our hotel in East Lavant need to close for the work?

In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Is a smaller place like East Lavant outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Can one contractor look after sealant on all our buildings?

Yes. Send a list of addresses and what’s needed at each, and we’ll put together a fixed quote and a sensible order of work.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

What East Lavant’s businesses ask us to seal

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Several hotels sit less than 2 miles from East Lavant. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let.

If you look after units at a retail site such as Summersdale Retail Park, 0.7 miles south-west of East Lavant, shopfront perimeters and shop-fit joints are where a matched colour shows. Premises within reach of Chichester station, 2.5 miles to the south of East Lavant, often have busy frontages where joints are seen by everyone passing.

East Lavant is about 2 miles north of Chichester, in West Sussex. We cover commercial sites throughout East Lavant. We work across 373 places in West Sussex, from busy centres to rural villages. We also cover Portsmouth, some 14 miles away.

Postcode districts covered here: PO18 for sealant joints. If your site is on Pook Lane, Fordwater Road and Shop Lane or close by, we can quote for sealant joints. Sites close to East Lavant are covered too, including Mid Lavant (1 mile north-west), Westerton (2 miles south-east), Westhampnett (2 miles south-east), Waterbeach (2 miles east) and Maudlin (2 miles south-east). A short drive away, we cover Bognor Regis (7 miles south-east), Selsey (9 miles south), Littlehampton (11 miles east), Rustington (12 miles east), Storrington (15 miles east) and Angmering (13 miles east).

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours to several days on most single sites, depending on joint lengths and access, and we clear our waste as we work. Rural sites near East Lavant may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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

Why it’s worth doing now in East Lavant

Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Converted and older buildings near places like East Lavant tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Constructionline member
  • Our applicators hold CSCS cards
  • A fixed quote before work starts
  • CHAS accredited

Building owners, agents and FMs in East Lavant

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

What we are called out for in East Lavant

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Any of the following is a good reason to get the joints checked over:

  • Sanitary sealant that has gone black and patchy
  • Earlier reseals applied straight onto the failed bead
  • Wall and floor joints that have lost their seal
  • Window and door perimeter joints that have cracked open

If you have premises on more than one site, say at Summersdale Retail Park and St James Industrial Estate., one contractor and one quote can cover both.

Comparing quotes

  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long
