When to call us in Wantage

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 all let go sooner than they should. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.

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

  • Leaks that seem to come through a sealant line
  • Smeared sealant across finishes from a rushed job
  • External beads that have gone brittle and cracked
  • Mouldy silicone around WCs, urinals and vanity tops

Refits at hotels like Blue Boar Hotel (to the south of Wantage) bring joints at vanity tops, bars and reception desks that guests see every day.

What your quote should include

  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?
  • What site paperwork they can supply

How to choose a sealant contractor

Commercial sealant contractors for commercial buildings in Wantage

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: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Wantage, call 01277 525 020 or email a schedule or drawings with the site addresses. We work on external facade joints, movement joints in walls and floors and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are hardened, chalky sealant on south-facing or exposed elevations and leaks that seem to come through a sealant line. Most enquiries from Wantage start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

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

Many businesses in towns like Wantage work from older buildings that have been altered more than once. Joints where brick or render meets a newer frame or panel move differently, so the sealant has to suit both sides.

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

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a town like Wantage, we try to group jobs for the same client into one visit, with one quote covering them. Tell us when the building is open and we will plan to suit.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Point out parking and an unloading spot

Advice

For managing agents and facilities managers

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.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Surface by surface

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.

Your questions answered

What site paperwork comes with a job in Wantage?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Elms Farm Business Park, near Wantage, within your area?

Yes. Our area takes in Wantage and its surroundings, with estates and business parks such as Elms Farm Business Park included. A few photographs and the unit address let us price the work.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Which sealant the job calls for
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements

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

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • Your programme or deadline
  • The asbestos register, for older buildings
  • Clear photographs of the problem areas
  • The product your specification calls for

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or email the details over if you’d rather talk the job through.

Sealant on show in Wantage’s commercial buildings

At least three named trading, business or retail sites lie within about 3 miles of Wantage. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. Wantage has five care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound; colours can be chosen to suit the interior.

If you run an office at a site such as Elms Farm Business Park, which lies north of Wantage, the sealant at reception desks, tea points and frames ages with each fit-out. If you have premises on more than one site, say at Elms Farm Business Park and Grovelands Shopping Centre, one contractor and one quote can cover both.

Wantage is about 8 miles west of Didcot, in Oxfordshire. Businesses, contractors and managing agents in Wantage use us for work on sealant joints, as part of our coverage of Oxfordshire. Our Oxfordshire coverage takes in 423 places. For work in that direction, see our Oxford page.

If your site is on Market Place, Limborough Road and Humber Close or close by, send details and we’ll quote for sealant joints.

We also cover Charlton (1 mile east), East Challow (1 mile west), Letcombe Regis (2 miles south-west), West Challow (2 miles west) and Childrey (2 miles west) for sealant joints. Further afield, our area takes in Oxford (14 miles north-east), Didcot (8 miles east), Abingdon-on-Thames (8 miles north-east), Witney (14 miles north), Carterton (14 miles north-west) and Faringdon (8 miles north-west).
