Commercial sealant contractors for West Lavington sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like West Lavington are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Flag any permit to work we’ll need

About our commercial sealant contractors in West Lavington

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. Outside, it closes facade joints, frame perimeters and movement joints against the weather. 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. We work on floor and threshold joints, window and door perimeters and washrooms and tea points, and what we are called in for most is smeared sealant across finishes from a rushed job and earlier reseals applied straight onto the failed bead. A specialist sealant contractor works differently from a general builder: on jobs in West Lavington, preparation and product choice get the time they need.

Occupied buildings in West Lavington need the work phased: washrooms in turn, floors in sections and entrances kept open.

Work in smaller places such as West Lavington tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

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.

How the job changes by surface

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal. We’ll confirm the colours available for the specified product.

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.

What we are called out for in West Lavington

Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.

If one of these sounds familiar, it’s time for a closer look:

  • Untidy joints in a reception, shop floor or lobby
  • Sanitary sealant that has gone black and patchy
  • Window and door perimeter joints that have cracked open
  • Hardened, chalky sealant on south-facing or exposed elevations

If you run a unit on an estate such as Holmbush Industrial Estate, 0.8 miles to the west of West Lavington, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

How to choose a sealant contractor

Frontages, fit-outs and joints in West Lavington

There are a number of hotels within about 2 miles of West Lavington. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading. West Lavington is about 45 miles from central London. The commuter belt holds a great many offices, retail parks and business parks. Multi-site occupiers here often want one sealant contractor across all their buildings.

Refits at hotels like The Spread Eagle Hotel, 0.5 miles north-west of West Lavington, bring joints at vanity tops, bars and reception desks that guests see every day. A business with units at Holmbush Industrial Estate and Midhurst Business Centre needn’t use two contractors for its sealant.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.

Where we work in West Lavington

  • Kitchen worktops and splashbacks
  • Window and door perimeters

West Lavington: questions and answers

Do you cover business parks and estates near West Lavington, such as Holmbush Industrial Estate?

Yes. Estates, retail parks and business parks around West Lavington, Holmbush Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is West Lavington off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is the old sealant taken out first?

Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.

Do you work directly for building managers?

Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. Tell us how you issue work and we will fit in.

Are you CHAS accredited and on Constructionline?

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

Can you supply RAMS and insurance details?

The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

How do we get a quote?

Send photos, drawings or a list of locations. If a visit is needed we will book one, and a fixed quote follows.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Check joints after other trades have worked nearby
  • Note dates and locations of sealant work for future planning
  • Deal with small splits before they become leaks
  • Put external and wet-area joints on a regular inspection round

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just give us a call on 01277 525 020 or use the quote form for a quote.

Tenants and staff spot black or split sealant quickly. Planned replacement saves fielding the same complaint again and again.
