Coloured sealant around Bosham: points for this area

Bosham sits close to the coast, within about 2 miles. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Where a frontage needs a particular colour, the product still has to suit that exposure. A 2-mile radius around Bosham takes in a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading.

For a hotel such as The Millstream Hotel, which lies west of Bosham, the colour of a joint at the bar or the bath matters to the look of the room. Sites a few miles apart, such as Southfield Industrial Park. And Broadbridge Business Centre, can share one programme and one point of contact.

Bosham is about 3 miles west of Chichester, in West Sussex. We send applicators to Bosham for colour-matched joints, handled exactly as we handle every other area. 373 places across West Sussex fall within our area, Bosham among them. We also cover Portsmouth, around 10 miles from Bosham.

Business premises anywhere in PO18 are within our area. Among the streets we cover are High Street, Viking Way and Merryweather Road, and sites on any of them can send details for a fixed quote. Just outside Bosham, we also work in Broadbridge (1 mile north-east), Chidham (1 mile west), Bosham Hoe (1 mile south), Nutbourne (2 miles north-west) and Fishbourne (2 miles east). A short drive away, we cover Bognor Regis (8 miles east), Chichester (3 miles east), Selsey (7 miles south-east), Littlehampton (14 miles east), Rustington (15 miles east) and Portfield (4 miles east).

Coloured sealant in Bosham, done properly

Colour is often written into the specification, by RAL reference or by matching a sample. Standard sealant ranges cover many colours, so we check what the specified product is made in at quote stage. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. We work on powder-coated and anodised frames, natural stone and brick and cladding panels, and the usual reasons a site gets in touch are discoloured joints on a visible elevation and dirty, discoloured joints in public areas. Whether you call it commercial sealant work, mastic application or joint sealing, in Bosham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sets the cost

We price every job individually. The main factors are:

  • Joint width, depth and condition
  • How accessible the joints are
  • Location, for remote and island sites
  • The product specified

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area
  • Where the site is, with the postcode

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Protect fresh coloured sealant from dust and handling
  • Approve a sample bead on high-profile areas
  • Avoid piecemeal repairs on coloured joints
  • Don’t let trades patch coloured joints with a random sealant

Note the sealant type and colour on the building file. Future repairs can then use the same colour.

Approve a sample where colour really matters. A sample in real light shows how it will look.

Why deal with it now?

Leaving a failed coloured joint risks more than appearance. Water through a split seal can stain or damage the surfaces next to it, so it’s worth fixing early. One visit to deal with every failing joint makes more sense than several trips to a place like Bosham. Send photographs of each area and we will quote for the lot.

There’s no price list, since every building and every scope is different. Call for a quote.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Colours confirmed for the specified product
  • Fully insured
  • A fixed quote before work starts

Bosham: questions and answers

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

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Will you take on work at estates like Southfield Industrial Park., close to Bosham?

Yes, sites like Southfield Industrial Park. Are within our area, along with the rest of Bosham. A few photographs and the unit address let us price the work.

Can we approve the colour on site?

Yes. Tell us who approves colour and we’ll plan the sample into the programme before the main run.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and we clear our waste as we work. If others near Bosham need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photographs of the finish are checked against the product’s range.
  3. A short trial length can be approved before the full run on visible work.
  4. We take out the existing bead, clean the joints and fit backing.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Getting the site ready

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Ask for a quote

For a fixed quote, call the office on 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.

Advice

What we’re called out for in Bosham

Older sealant changes colour over time. Sunlight, dirt and pollution can darken, yellow or chalk the surface. Resealing is the chance to reset the colour.

Most enquiries start with one or more of the following:

  • Untidy coloured beads with ragged edges
  • Stained or mouldy coloured joints in washrooms
  • Patch repairs in several different colours
  • Fit-outs with a sealant colour in the specification

Premises within reach of Bosham station, 0.8 miles north-east of Bosham, often have busy frontages where joints are seen by everyone passing.

What your quote should include

  • Their public liability cover
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed
  • How the existing material will be dealt with

Choosing a commercial sealant contractor

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
