About commercial sealant contractors in UB5

We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on external facade joints, window and door perimeters and movement joints in walls and floors, and what we are called in for most is damp patches where an external joint has failed and layers of sealant, all of them failing.

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go.

  1. First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

How we quote

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Shops, offices and hotels in UB5

In UB5, much commercial sealant work follows refits in shops, offices and hotels in places such as Ruislip, Harrow and Greenford. Visible joints call for a matched colour and a clean tooled finish.

We work across Greater London and the South East counties, so jobs in UB5 are planned with access, loading and parking in mind.

Northolt: Units at places like Victoria Retail park, 0.8 miles north-west of Northolt, are refitted as brands change, and the joints have to suit each new scheme. Sites a few miles apart, such as Northolt Industrial Estate and Kelvin Industrial Estate, can share one programme and one point of contact.

Commercial clients in UB5

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

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.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Act on the first lifting edges rather than waiting
  • Note dates and locations of sealant work for future planning
  • On pre-2000 buildings, share the asbestos information before work starts
  • Check joints after other trades have worked nearby

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early. Should something look amiss, you can give us a call on 01277 525 020 or use the quote form and send a picture.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.

What we’re called out for in UB5

The wrong sealant in the wrong place is a common cause of early failure. 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. BS 6213 gives guidance on choosing construction sealants.

Site and facilities staff are often the first to spot these:

  • Gaps behind commercial kitchen worktops and sinks
  • Smeared sealant across finishes from a rushed job
  • Wall and floor joints that have lost their seal
  • Sanitary sealant that has gone black and patchy

How the job changes by surface

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach. We seal to a neat, cleanable finish and work around service times you agree with us.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Water from a services leak rather than a joint
  • Old mastic that tests positive for asbestos
  • Structural cracks or movement the joints weren’t designed for

UB5: questions and answers

How do you keep disruption to occupiers down?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

Is it OK to apply fresh sealant over existing beads?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

What do you need from us to quote?

Send photos, drawings or a list of locations through the quote form on this site. Where we need to see it, we will arrange a site visit, then send a fixed quote.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What site paperwork can you provide?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Are you CHAS accredited and on Constructionline?

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