Coloured sealant for Newport sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

About our coloured sealant in Newport

Colour is often written into the specification, by RAL reference or by matching a sample. Most sealant types are made in a broad range of standard colours, so we check what the specified product is made in before we quote. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. If you have old sealant that has yellowed, darkened or faded and smeared sealant on stone or joinery, we can help, on natural stone and brick, powder-coated and anodised frames and cladding panels alike. Most enquiries from Newport start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A town such as Newport typically has a high street, some business units, schools and a surgery or two. Each has joints that wear: frontages, staff kitchens, washrooms and window perimeters, and where a frontage is on show, a matched colour keeps it looking right.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Commercial premises in Newport

There are five care or nursing homes within about 2 miles of Newport. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean; colours can be chosen to suit the interior. At least three named trading, business or retail sites lie within about 3 miles of Newport. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

For a retailer at a site such as Towngate Retail Park (less than half a mile north-east of Newport), the joints customers see are as much part of the fit-out as the shelving. A hotel such as The Bugle Hotel Tap, under half a mile to the north-east of Newport, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Newport is about 10 miles south-west of Gosport, in the Isle of Wight. Our applicators travel to Newport for work on colour-matched joints. Across the Isle of Wight, 125 places are covered, including Newport. Sites around Portsmouth have their own page, about 12 miles away.

Postcode districts covered here: PO30 for colour-matched joints. We cover commercial and managed buildings on High Street, Red Fox Square and Drill Hall Road. Newport sits on or close to the A3020 and A3054, useful when we plan access and materials. Close to Newport, our area also takes in Shide (1 mile south-east), Blackwater (2 miles south), Downend (2 miles east), Merstone (3 miles south-east) and Rookley (3 miles south). Further afield, our area takes in Ryde (6 miles east), Cowes (4 miles north), Sandown (7 miles south-east), Shanklin (7 miles south-east), Ventnor (8 miles south-east) and East Cowes (4 miles north). Newport is one of the busier places in the Isle of Wight, and we take on colour-matched joints for its commercial and public buildings. Where a site is remote or on an island, we plan travel and materials carefully, so the full address helps from the start.

Your questions answered

Can you work at a site such as Towngate Retail Park, by Newport?

Yes. We cover Newport and the area around it, including industrial estates, business parks and retail parks such as Towngate Retail Park. Send details of the unit and the work through our quote form for a quick quote.

Must a hotel around Newport close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Will sunlight affect the sealant colour?

It can, to a degree. How much depends on the product, the colour and the exposure.

Can staff carry on working while you are here?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can we specify the colour by RAL number?

Yes. We compare the RAL reference with the colours made for the specified sealant. You’ll see the nearest options.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

When it isn’t the sealant

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

  • Stopping sealant from ever changing colour outdoors
  • Repairing damaged frames or cladding
  • A guaranteed perfect match to every finish

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

What we are called out for in Newport

When frames are recoated or a space is rebranded, the old joints may no longer suit. Refurbishments and rebrands often bring a new colour scheme that the sealant has to follow.

These are often picked up first by site or facilities staff:

  • A bead that fights the cladding or frame colour
  • Sealant that no longer suits recoated frames
  • Coloured joints that have cracked with movement
  • Marked sealant in hotel bathrooms

If you have premises on more than one site, say at Towngate Retail Park and Wakes Retail Park, one contractor and one quote can cover both.

What your quote should include

  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • Who will actually carry out the work
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

How the job changes by surface

Powder-coated and anodised frames

Anodised and metallic frames rarely have an identical sealant colour. We show you the closest options in the product’s range so you can choose.

Hotel interiors

Hotels use colour-matched sealant in bathrooms, bedrooms and public areas. Sanitary silicone comes in colours too, including shades for tiled and stone bathrooms.

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 area is protected, prepared and sealed, then handed back before we move to the next. For a town like Newport, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we will fit the work in.

  1. We confirm the product the joint needs before talking about colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. A short trial length can be approved before the full run on visible work.
  4. We remove the existing bead, clean the faces and set the depth.
  5. The coloured sealant is applied and tooled with clean, masked edges.

Getting the site ready

  • Let us know about inductions and permits
  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Advice

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Use one colour standard across multi-site work
  • Insist on the agreed colour for any repair
  • Reseal whole runs rather than patching single joints
  • Brief cleaners about newly sealed joints

Let the joints cure as the manufacturer advises before they’re cleaned. Fresh coloured beads show fingerprints and dust more easily, so brief cleaners and other trades.

Include coloured joints in a planned maintenance cycle. A planned reseal avoids a run of patch repairs.
