Sealant specialists in Viables

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Viables, the quickest start is to call 01277 525 020 or email the details over with a list of addresses. If you have external beads that have gone brittle and cracked and greasy, split joints in a kitchen or tea point, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Viables, that means joint design, primers and backing rod as standard.

Occupied buildings in Viables need the work phased: we agree the order with you and hand back each area with its cure time.

In a smaller place such as Viables, commercial buildings are usually a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a job in Viables, the main thing is a clear picture of the work. A fixed quote follows.

  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. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Different surfaces, different methods

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Your questions answered

Is a smaller place like Viables outside your area?

Not at all. Viables is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Viables Industrial Estate, near Viables?

Yes. We cover Viables and the area around it, including industrial estates, business parks and retail parks such as Viables Industrial Estate. A few photographs and the unit address let us price the work.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Is failed sealant stripped out, or sealed over?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Does commercial sealant work come with a guarantee?

Each job sits under our 12-month guarantee from handover. Looking after the joints as we advise helps them last.

Working on commercial sites near Viables

There are plenty of hotels within about 2 miles of Viables. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading. Two care or nursing homes sit less than 2 miles from Viables. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior.

For premises near Basingstoke station, 1.3 miles north of Viables, footfall is part of the plan: work is phased so shops and offices keep trading. Shopping centres and retail parks such as St Michael's Retail Park, 0.8 miles to the west of Viables, see a steady turnover of shop fits, each leaving joints where colour and finish matter.

Viables is about 1 mile south-east of Basingstoke, in Hampshire. Any commercial site in Viables is covered, whether it’s a single job or part of a planned programme. We work across 723 places in Hampshire, from busy centres to rural villages. There’s a separate page for Reading, about 15 miles away.

Work on sealant joints is covered throughout RG21, RG22 and RG25, whatever the building. Streets here include Grove Road, Porter Road and Morley Road. If your building is just outside Viables, we cover Cliddesden (1 mile south), Eastrop (1 mile north), Oakridge (1 mile north), Lychpit (2 miles north-east) and Old Basing (2 miles north-east). A short drive away, we cover Farnborough (14 miles east), Fleet (11 miles east), Aldershot (14 miles east), Alton (8 miles south-east), Yateley (13 miles north-east) and Tadley (8 miles north).

Local landmarks in Viables

Around Viables, our work takes us to commercial buildings near The Costello School, Queen Mary's College and Hackwood Park and the streets around them. The nearest railway station is Basingstoke station, roughly 1.3 miles north. Well-known places in the area include Willis Museum (0.9 miles north) and Festival Place (1.1 miles north). Not far away are The Mill Field and Farleigh Hill.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Roof leaks that only look like a joint problem
  • Old mastic that tests positive for asbestos
  • Structural cracks or movement the joints weren’t designed for

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

Why deal with it now?

Putting off a reseal normally moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next. Dealing with it while the damage stops at the bead is the cheaper route. In a smaller place such as Viables, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Read what affects the cost and our accreditations and insurance.

What sets the cost

What shapes the price:

  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • Any access equipment needed

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What we need to price the job

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

  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Do you need commercial sealant contractors in Viables?

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 all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Clients typically get in touch after noticing something like this:

  • Smeared sealant across finishes from a rushed job
  • Expansion joints with the sealant torn out
  • Mouldy silicone around WCs, urinals and vanity tops
  • Leaks that seem to come through a sealant line

If you have premises on more than one site, say at Viables Industrial Estate and Brunswick Place Industrial Estate, one contractor and one quote can cover both.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Which product they’ll use, and why it suits the joint
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
