Coloured sealant in Newtown Common

Shop fits, hotels and offices are where colour-matched sealant earns its place. A grey bead on a black shopfront or a white line against oak looks like a defect. We pick a colour from the product’s range that sits with the finish. Most enquiries involve old colour-matched joints lifting at the edges and dirty, discoloured joints in public areas, across powder-coated and anodised frames, hotel bathrooms and public areas and natural stone and brick. Facilities teams, main contractors and managing agents in Newtown Common tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Work in smaller places such as Newtown Common tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?

Across a chain of shops or hotels, consistency matters. Fixing the colour reference at the start keeps every site the same. One visit to deal with every failing joint makes more sense than several trips to a place like Newtown Common. Send photographs of each area and we will quote for the lot.

A quote for colour-matched joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • CHAS accredited
  • Sealing commercial buildings since 2005
  • RAL and finish matching where the product range allows

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Newtown Common are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Flag any permit to work we will need

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Related advice

Common problems we fix in Newtown Common

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

What tends to prompt an enquiry:

  • Fit-outs with a sealant colour in the specification
  • Poorly tooled joints on visible finishes
  • Weathered sealant that no longer matches
  • Dirty, discoloured joints in public areas

A business with units at Newbury Retail Park and New Greenham Business Park needn’t use two contractors for its sealant.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • A colour that never alters with age
  • Overpainting a joint that needs a non-paintable product
  • Exact bespoke colour matches beyond the product’s range

Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Building owners, agents and FMs in Newtown Common

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
