About our coloured sealant in Worthy Down

Window, door and shopfront frames in RAL finishes often need a sealant to suit. We compare the RAL reference with the colours made for the specified sealant, and you approve the choice. Where nothing in the range is close enough, a paintable hybrid or PU sealant may be an alternative, if the joint and specification allow. If you have old colour-matched joints lifting at the edges and a run of joints in mismatched shades, we can put it right, on shop-fit joinery and counters, office fit-out finishes and natural stone and brick alike. A single leaking joint is often how a building in Worthy Down first comes to us: we look at the rest while we are there and tell you what we find.

A job in a smaller place like Worthy Down 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.

A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • A colour that never alters with age
  • Paint over sealant on joints that move too much
  • Cleaning or repairing the surrounding finishes

If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

What we seal

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

Common problems we fix in Worthy Down

A coloured joint can fail like any other: splits, adhesion loss and hardening all happen. We cut out and reseal in the agreed colour.

Look out for the following:

  • Joints that need to match a new RAL frame colour
  • White or grey sealant that clashes with the finish
  • Hotel refurbishments with a set colour scheme
  • Poorly tooled joints on visible finishes

If you run a unit on an estate such as Beeches Industrial Park, 1.9 miles to the west of Worthy Down, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

Commercial premises in Worthy Down

At about 60 miles from central London, Worthy Down is within reach of the capital. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. Worthy Down has two named business or industrial parks inside a 3-mile radius.

If you have premises on more than one site, say at Beeches Industrial Park and Balldown Business Centre, one contractor and one quote can cover both. Premises within reach of Winchester station, 3.2 miles south of Worthy Down, often have busy frontages where joints are seen by everyone passing.

Common questions from Worthy Down clients

Do you offer colour-matched sealant for buildings in Worthy Down?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Can you work at a site such as Beeches Industrial Park, by Worthy Down?

Yes. We cover Worthy Down and the area around it, including industrial estates, business parks and retail parks such as Beeches Industrial Park. A few photos and the unit address let us price the work.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Are you CHAS accredited and on Constructionline?

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

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you cover Worthy Down?

Yes. Sites across Worthy Down are covered.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the job changes by surface

Paintable sealants

Where no colour in the range is close, a paintable hybrid or PU sealant can sometimes be painted to match. That only works where the joint and specification allow it.

Natural stone

Natural stone rarely has one colour, and the sealant has to work with that. A stone-compatible, neutral-cure sealant avoids staining in the closest available colour.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Jobs in and around smaller places like Worthy Down are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. We mask, seal and tool to a clean line.
  6. We remove the masking and walk the finished joints with you.

Before we start on site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
