How we handle commercial sealant contractors in Rock

Inside a commercial building, sealant does a lot of quiet work: 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. We deal with internal and external sealant joints alike. If you have frame sealant that has cracked, shrunk or pulled away and mouldy silicone around WCs, urinals and vanity tops, we can help, whatever the surface. Whoever orders the work in Rock, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

If you look after more than one building near Rock, the work can be planned as one programme, with one quote format and one point of contact.

Rural business units near smaller places such as Rock are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we’re called out for in Rock

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

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

  • Shrunken sealant along kitchen worktops and splashbacks
  • Expansion joints with the sealant torn out
  • Smeared sealant across finishes from a rushed job
  • Sanitary sealant that has gone black and patchy

If you run an office at a site such as Rock Business Park, less than half a mile to the east of Rock, the sealant at reception desks, tea points and frames ages with each fit-out.

Our contractor checklist

What happens if it’s left?

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation. You notice the difference years later, not on the day. Halls, stores and units around places like Rock may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • Workmanship guaranteed for 12 months
  • A fixed quote before work starts
  • Constructionline member for supplier checks
  • Colour options checked against the specified product

See what affects the cost and our accreditations and insurance.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • A failed roof covering or waterproofing membrane
  • Water from a services leak rather than a joint
  • Cracking that needs a structural engineer to look at it

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.

Where we work in Rock

  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • External facade joints
  • Washrooms and tea points
  • Movement joints in walls and floors
  • Window and door perimeters

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Access and working height

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • Drawings or a marked-up plan, if available
  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Commercial clients in Rock

Hospitality, education, healthcare, office and retail clients 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.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Rock can sit alongside others in a wider programme across West Sussex.

Common questions from Rock clients

Is a smaller place like Rock outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you cover business parks and estates near Rock, such as Rock Business Park?

Yes. We cover Rock and the area around it, including industrial estates, business parks and retail parks such as Rock Business Park. Send details of the unit and the work through our quote form for a quick quote.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

How do you keep disruption to occupiers down?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long does a typical visit take?

It depends on the scope, though a typical visit normally takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Commercial premises in Rock

Rock is about 43 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Rock has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

In hotels such as Mill House Hotel, 1.1 miles north-east of Rock, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Occupiers with premises at both Rock Business Park and Wiston Business Park could have the sealant at each handled under one quote.
