How we handle coloured sealant in Newtown

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. We don’t promise an exact custom match, but we will show you the closest options. We work on office fit-out finishes, natural stone and brick and shop-fit joinery and counters, and the usual reasons a site gets in touch are coloured joints that have cracked with movement and standard-colour sealant spoiling a high-end finish. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Newtown is the same: the right product in a properly prepared joint.

In a smaller place such as Newtown, commercial buildings are normally a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

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

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Newtown can form part of a wider programme.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few hours or a phased programme, depending on joint lengths and how many colours are involved, and our waste is bagged and taken away as we go. What matters most for a job in Newtown is a clear list of what needs doing. You will then get a fixed price for the work.

  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. Where colour is critical, a sample bead can be agreed in a discreet spot.
  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.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

Common problems we fix in Newtown

Mould and staining discolour coloured joints in some areas. Mould that has rooted into a bead rarely cleans out.

Clients normally get in touch after noticing something like this:

  • Patch repairs in several different colours
  • Stained or mouldy coloured joints in washrooms
  • Joints that need to match a new RAL frame colour
  • Discoloured joints on a visible elevation

A hotel such as Tower House Hotel, under half a mile south-east of Newtown, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

How to choose a sealant contractor

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

FAQs: Newtown

Is a smaller place like Newtown outside your area?

Not at all. Newtown is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Are you CHAS accredited?

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

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Do you use coloured sanitary silicone?

Yes, in many cases. Hotel bathrooms, washrooms and kitchens often use coloured sanitary silicone to suit tiles or stone.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Stopping sealant from ever changing colour outdoors
  • A guaranteed perfect match to every finish
  • Finishes that change colour from one area to another

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Surfaces we seal

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

Why act early in Newtown

A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Fixing the colour reference at the start keeps every site the same from one fit-out to the next. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Why us?

  • Over 20 years of commercial sealing
  • Work carried out by CSCS-carded applicators
  • Fully insured
  • Joints cleaned back to sound surfaces

Sites a few miles apart, such as Suttons Business Park and Forbury Retail Park, can share one programme and one point of contact. Offices and shops close to stations such as Reading station (1.1 miles west of Newtown) tend to be busy all day, so sealant work is planned around opening hours.
