Coloured sealant in Horsham

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Coloured sealant in Horsham

Matching to anodised or powder-coated frames is a common request. 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. Most enquiries involve a run of joints in mismatched shades and weathered sealant that no longer matches, on shop-fit joinery and counters, cladding panels and hotel bathrooms and public areas. Looking for mastic applicators who cover Horsham? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Places the size of Horsham normally have a broad commercial mix: offices on business parks, shopping centres and retail parks, hotels and healthcare buildings. That variety is why a single contractor covering several premises can help.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions about Horsham

Do you cover business parks and estates near Horsham, such as Nightingale Trading Estate?

Yes, sites like Nightingale Trading Estate are within our area, along with the rest of Horsham. A few photos and the unit address let us price the work.

Will our hotel in Horsham need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

What do you charge?

We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.

Is Horsham in your area?

Yes. Horsham falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How long does a typical visit take?

It depends on the scope, but the work normally takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For bigger or phased jobs, we’ll set out a timescale with the quote.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

How the job changes by surface

Cladding panels

Where panels vary in colour, the joint colour is agreed for the whole elevation. A neutral tone from the range often works best, and a sample settles it.

Paintable sealants

Some joints are better sealed with a paintable product and decorated. It depends on movement and the specification, as paint can crack on a moving joint.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Town-centre jobs in Horsham can mean limited parking and loading, while out-of-town estates normally have yards and car parks. Either way, tell us what’s available.

  1. We start with photos, drawings or a visit to see the finishes.
  2. Colour options from the specified product’s range are shared with you.
  3. The programme and access are agreed, including any phasing.
  4. Joints are prepared, primed where specified and backed.
  5. We seal in the approved colour and tool it smooth.

Getting the site ready

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Materials with mixed tones that defy a single match
  • Paint over sealant on joints that move too much
  • Exact bespoke colour matches beyond the product’s range

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

Surfaces we seal

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

Shops, offices and hotels in and around Horsham

Horsham has a number of hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading. The 2 miles around Horsham include eight care or nursing homes. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound.

A business with units at Nightingale Trading Estate and Tanbridge Retail Park needn’t use two contractors for its sealant. If you run a unit on an estate such as Nightingale Trading Estate, which lies north-east of Horsham, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. For premises near Horsham station, which lies east of Horsham, footfall is part of the plan: work is phased so shops and offices keep trading.
