About our coloured sealant in South Wonston

A colour-matched bead still has to work as a seal. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only, exactly as for a standard colour. Clean masking and steady tooling give the sharp lines colour work needs. If you’re dealing with poorly tooled joints on visible finishes and coloured joints that have cracked with movement, we can put it right. A specialist sealant contractor works differently from a general builder: in South Wonston, that means joint design, primers and backing rod as standard.

A job in a smaller place like South Wonston is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Building owners, agents and FMs in South Wonston

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Don’t let trades patch coloured joints with a random sealant
  • Settle the colour with the designer at the start
  • Plan full-run reseals on visible elevations
  • Look at the cured colour before the full run

Let the joints cure as the manufacturer advises before they’re cleaned. Coloured sealant marks more visibly than white while it is fresh, so brief cleaners and other trades.

Ask for a trial bead on high-profile areas. Seeing the cured colour in place avoids surprises.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around South Wonston, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photos of the finish are checked against the product’s range.
  3. A short trial length can be approved before the full run on visible work.
  4. We take out the existing bead, clean the joints and fit backing.
  5. The coloured sealant is applied and tooled with clean, masked edges.

Preparing the site

  • Point out any areas we must not close
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints

Advice

South Wonston: questions and answers

Is South Wonston off your patch?

No. Places such as South Wonston 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.

Is Beeches Industrial Park, near South Wonston, within your area?

Yes, sites like Beeches Industrial Park are within our area, along with the rest of South Wonston. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How long do sealant joints last?

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

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will the colour fade over time?

Some change is normal outdoors. Sunlight, dirt and weathering affect how it looks, which is why exposed joints are inspected and resealed when needed.

Why act early in South Wonston

A failed joint lets in water and dirt, whatever colour it is. Water through a split seal can stain or damage the surfaces next to it. Around South Wonston, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • A colour that never alters with age
  • Paint over sealant on joints that move too much
  • Custom-mixed sealant colours

If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

Where we work in South Wonston

  • Powder-coated and anodised frames
  • Office fit-out finishes
  • Cladding panels
  • Shop-fit joinery and counters
  • Natural stone and brick
  • Hotel bathrooms and public areas

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Which sealant the job calls for
  • Distance, for remote addresses
  • The site’s rules and procedures
  • Quantities, in metres or numbers

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Sending details for a quote

We can often quote from photographs and a few details. Please tell us:

  • How the joints are reached, and at what height
  • Whether the building will be occupied during the work
  • The site address and postcode
  • A wide shot and a close-up of the area

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
