Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Look at the cured colour before the full run
  • Keep harsh solvents away from visible joints
  • Use one colour standard across multi-site work
  • Avoid piecemeal repairs on coloured joints

Don’t let anyone patch a coloured joint with whatever sealant is to hand. Wrong-colour patches are obvious, so it is better to reseal the section properly.

Settle the colour early in the project. When colour is left to the last minute, it is often wrong.

How we handle coloured sealant in Somerton

Coloured sealant is a finishing trade, so it typically comes late in a programme. We work around other trades and protect adjacent finishes, and we leave the area clean. A 12-month guarantee covers our workmanship. We work on hotel bathrooms and public areas, natural stone and brick and shop-fit joinery and counters, and the failures we’re asked to look at most are dirty, discoloured joints in public areas and joints that need to match a new RAL frame colour. Facilities teams, main contractors and managing agents in Somerton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places such as Somerton, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

From enquiry to sign-off

Occupied buildings need a little choreography. 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. Rural sites near Somerton may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We confirm the product the joint needs before talking about colour.
  2. Colour references, samples or photos of the finish are checked against the product’s range.
  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.

Cost factors for colour-matched joints

A fixed quote reflects the actual work. It takes account of:

  • How much there is to seal
  • Travel to remote or island sites
  • Working within restricted access windows
  • Joint width, depth and condition

A quote for colour-matched joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

However big the job, these details speed things up:

  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • What the building is and how it’s used

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Somerton can sit alongside others in a wider programme.

Surface by surface

Office fit-outs

Office fit-outs include glazed partitions, kitchens, washrooms and reception areas. Colour-matched joints keep the finish consistent across floors.

Brick and masonry

Brickwork joints typically look best in a colour close to the mortar or brick. The nearest colour in the range is agreed with you.

Why it’s worth doing now in Somerton

A failed joint lets in water and dirt, whatever colour it is. Water through a split seal can stain or damage the surfaces next to it, so it’s worth fixing early. Older rural buildings around Somerton move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

FAQs: Somerton

Is Somerton too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Hatch End Old Industrial Estate, by Somerton?

Yes, sites like Hatch End Old Industrial Estate are within our area, along with the rest of Somerton. Send details of the unit and the work through our quote form for a quick quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How do we ask for a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

Does coloured sealant change colour outdoors?

Exposed sealant can change in appearance over the years. UV and grime can soften or alter the colour, which is why exposed joints are inspected and resealed when needed.

Can we see a sample before the full job?

Yes. Tell us who approves colour and we’ll plan the sample into the programme before the main run.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What Somerton’s businesses ask us to seal

At about 60 miles from central London, Somerton is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all. Somerton sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Premises within reach of Heyford station (to the south of Somerton) often have busy frontages where joints are seen by everyone passing. On estates like Hatch End Old Industrial Estate (2 miles south-west of Somerton), the office and welfare end of each unit has its own sealant to maintain.

Somerton is about 6 miles north-west of Bicester, in Oxfordshire. We send applicators to Somerton for colour-matched joints, handled exactly as we handle every other area. We work across 423 places in Oxfordshire. For work in that direction, see our Oxford page.
