Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Note dates and locations of sealant work for future planning
  • Report cracked or peeling sealant early
  • Keep barriers up until the new sealant has cured
  • Ask cleaners to use a soft cloth and mild cleaner on sealant

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.

Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.

About our commercial sealant contractors in Petworth

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Petworth, speak to us on 01277 525 020 or email drawings and photos with the site addresses. We work on washrooms and tea points, floor and threshold joints and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are layers of sealant, all of them failing and expansion joints with the sealant torn out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Petworth, that means joint design, primers and backing rod as standard.

Multi-site clients with buildings in and around Petworth can put several sites on one programme, so standards and paperwork match across every site.

Commercial sealant work around smaller places like Petworth 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Petworth as everywhere else we work. If our installation lets you down in that time, we return and fix it.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few hours for one area, or a planned series of visits across a bigger building, and we clear our waste as we work. For work around Petworth, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  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.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Flag any permit to work we will need
  • Tell staff and tenants when we’ll be in

When to call us in Petworth

No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once, so periodic inspection matters more than any date on a schedule.

Common reasons buildings call us in:

  • Smeared sealant across finishes from a rushed job
  • Black mould through washroom sealant that won’t clean off
  • Gaps behind commercial kitchen worktops and sinks
  • Weathered facade sealant that no longer flexes

In hotels such as The Angel Hotel, under half a mile north-east of Petworth, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Choosing a commercial sealant contractor

What Petworth’s businesses ask us to seal

There are two care or nursing homes within about 2 miles of Petworth. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean. At about 42 miles from central London, Petworth is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

For premises near Pulborough station, 4.4 miles to the south-east of Petworth, footfall is part of the plan: work is phased so shops and offices keep trading. A unit on an estate like Hampers Common Industrial Estate, 0.7 miles to the north of Petworth, typically has an office front, a trade counter and staff facilities with joints of their own.

Petworth is about 12 miles north-east of Chichester, in West Sussex. Petworth sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 373 places in West Sussex, from busy centres to rural villages. There’s a separate page for Brighton, about 23 miles away.

Work on sealant joints is covered throughout GU28, for business premises of every kind. For a building on Station Road, Back Lane and Rosemary Lane or nearby, we can quote for sealant joints.

FAQs: Petworth

Is a smaller place like Petworth outside your area?

No. Places such as Petworth are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

How is commercial sealant work priced?

Send what you have, even a few photos and rough lengths. We follow up with questions or a visit where needed.

Is it OK to apply fresh sealant over existing beads?

Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.

Could the old sealant in an older building contain asbestos?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can areas stay open during the work?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance.

Why it’s worth doing now in Petworth

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, which is where the lasting value is. Older rural buildings around Petworth move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • RAL and finish matching where the product range allows
  • 12 months’ guarantee on every job
  • Sealing commercial buildings since 2005
  • Work carried out by CSCS-carded applicators

Take a look at our cost guide or our accreditations.

Cost factors for sealant joints

We price every job individually. The things that drive the figure:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Access and working height
  • Site requirements such as inductions and permits

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

However big the job, these details speed things up:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email drawings and photos.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
