Commercial sealant contractors for businesses in Selsey

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

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep a record of which joints were resealed and when
  • Put external and wet-area joints on a regular inspection round
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Ask fit-out and M&E contractors to report any sealant they disturb

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Tenants and staff spot black or split sealant quickly, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.

About our commercial sealant contractors in Selsey

Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, handled with the same process each time: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Selsey, give us a call on 01277 525 020 or email a schedule or drawings with the site addresses. The enquiries we see most involve gaps behind commercial kitchen worktops and sinks and wall and floor joints that have lost their seal, on kitchen worktops and splashbacks, window and door perimeters and washrooms and tea points. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Selsey is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A lot of what we do in Selsey is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

For a business or landlord in Selsey with one or two premises, it makes sense to bundle sealant jobs together: say a shopfront perimeter, a tea point, a washroom and some frames. One fixed quote then covers the lot.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Commercial sealant contractors around Selsey: what changes locally

The sea is no more than about 1 mile from Selsey. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. A matched colour is only half the brief on an exposed frontage. Selsey lies roughly 61 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Offices at parks like Selsey Business Centre (to the south-west of Selsey) have receptions, kitchens and glazed partitions where a tidy joint matters. If you have premises on more than one site, say at Selsey Business Centre and Trident Business Park, one contractor and one quote can cover both.

Selsey is about 6 miles south-west of Bognor Regis, in West Sussex. We cover commercial sites throughout Selsey, whether it’s a single job or part of a planned programme. Across West Sussex, 373 places are covered, Selsey among them. We also cover Portsmouth, some 14 miles away.

If you need commercial sealant contractors in PO20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In a town such as Selsey, most jobs are single buildings. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Get a fixed quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Advice

How the job changes by surface

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.

Shop fronts and retail fit-outs

Retail work usually has to fit around trading. Tell us your trading hours and access windows and we will plan around them.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Quoting for work in Selsey

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Backing rod, priming and other preparation
  • Access and working height
  • Site requirements such as inductions and permits

A quote for sealant joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What we need to price the job

To price the job accurately, we need to understand the site. Useful things to include:

  • The product your specification calls for
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older

To get a fixed quote, call 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.

Why it’s worth doing now in Selsey

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. In Selsey, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

  • Specification-led, product-correct work

FAQs: Selsey

Can you work at a site such as Selsey Business Centre, by Selsey?

Yes. Estates, retail parks and business parks around Selsey, Selsey Business Centre among them, are all within reach. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Our building in Selsey is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Are you CHAS accredited?

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