Coloured sealant for commercial buildings in Ashburton

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints. On resealing, matching the existing colour is often as important as the seal itself, particularly where the building’s look matters. We work on cladding panels, natural stone and brick and powder-coated and anodised frames, and the usual reasons a site gets in touch are weathered sealant that no longer matches and white or grey sealant that clashes with the finish. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ashburton is the same: the right product in a properly prepared joint.

Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Cleaning or repairing the surrounding finishes
  • Colour variation across natural stone or brick that no single shade can match
  • Exact bespoke colour matches beyond the product’s range

If in doubt, call 01277 525 020 or use the quote form and we will say what we think before you book.

Your questions answered

Do you take on jobs in Ashburton where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.

Does your area include sites such as Chaffinch Business Park, near Ashburton?

Yes. Our area takes in Ashburton and its surroundings, with estates and business parks such as Chaffinch Business Park included. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Do you do a sample bead?

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

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

Will sunlight affect the sealant colour?

It can, to a degree. Exposure, product and colour all play a part, so no colour stays exactly the same for ever.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Signs you need coloured sealant in Ashburton

A coloured joint can fail like any other: splits, adhesion loss and hardening all happen. The fix is a full cut-out and a new bead in the right colour.

Most enquiries start with one or more of the following:

  • Standard-colour sealant spoiling a high-end finish
  • Old sealant that has yellowed, darkened or faded
  • Stained or mouldy coloured joints in washrooms
  • Untidy coloured beads with ragged edges

If you run an office at a site such as Chaffinch Business Park, 1 mile to the north-east of Ashburton, the sealant at reception desks, tea points and frames ages with each fit-out.

Before you book anyone

  • What the guarantee covers, and for how long
  • Is the sealant right for the movement and the substrate?
  • Their public liability cover
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Planning a London job such as one in Ashburton starts with access. Send the building rules and access times with your enquiry.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. The programme and access are agreed, including any phasing.
  4. Joints are prepared, primed where specified and backed.
  5. The agreed colour is installed and tooled neatly.

What we need from you

  • Tell us which areas need to stay in use
  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs

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.

Building owners and managing agents use us on everything from one building to a spread of sites around Ashburton. One quote can cover more than one site, so there’s one set of paperwork to deal with.

The area within 2 miles of Ashburton holds plenty of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme.

Refits at hotels like Croydon Park Hotel, 1.4 miles to the south-west of Ashburton, bring joints at vanity tops, bars and reception desks that guests see every day. A business with units at Chaffinch Business Park and Franklin Industrial Estate needn’t use two contractors for its sealant.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • How much there is to seal
  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • When you need the work done
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas

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

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
