About our coloured sealant in Marston

Coloured sealant is a finishing trade, so it usually comes late in a programme. We work around other trades and protect adjacent finishes, and snag any marks before we leave. A 12-month guarantee covers our workmanship. If you’re dealing with joints that need to match a new RAL frame colour and dirty, discoloured joints in public areas, we can put it right. Looking for mastic applicators who cover Marston? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Business units in the countryside around places like Marston are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When to call us in Marston

A change of finish can leave existing sealant mismatched. New cladding colours, repainted frames or a refreshed shop fit all prompt colour changes, and the joints need to match.

Common reasons buildings call us in:

  • Untidy coloured beads with ragged edges
  • Previous reseals that don’t match the original
  • Dirty, discoloured joints in public areas
  • Joints that need to match a new RAL frame colour

For a hotel such as Galaxie Hotel (1.2 miles west of Marston), the colour of a joint at the bar or the bath matters to the look of the room.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • Whether their applicators hold CSCS cards
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Maintenance after handover

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

  • Put the colour reference on the finishes schedule
  • Look at the cured colour before the full run
  • Don’t let trades patch coloured joints with a random sealant
  • Keep the same sealant colour across a brand

Expect some change in appearance over the years. That is normal for exposed sealant, and resealing restores the look when the time comes.

Include coloured joints in a planned maintenance cycle. Replacing them on a schedule keeps finishes looking right over the years.

What the job involves on each surface

Hotel interiors

Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we will plan around them.

Natural stone

Sandstone, limestone and granite each have distinct tones. We choose from the product’s range and agree the colour with you.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The total length or number of joints
  • Which sealant the job calls for
  • Working within restricted access windows
  • The size and state of each joint

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • The site address and postcode
  • Access details, including height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or use the quote form.

Questions about Marston

Do you cover business parks and estates near Marston, such as Jordan Hill Business Park?

Yes. Our area takes in Marston and its surroundings, with estates and business parks such as Jordan Hill Business Park included. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do hotels near Marston have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Which sealant will you use?

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.

How do we ask for a quote?

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

Do you do a sample bead?

Yes. A trial length can be applied and approved before the full run. The colour can shift a little as it cures.

Can wet areas have colour-matched sealant?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified and agree it with you.

Will the colour fade over time?

Exposed sealant can change in appearance over the years. Sunlight, dirt and weathering affect how it looks, and resealing brings the look back.

What sealant work can’t fix

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

  • Paint over sealant on joints that move too much
  • A guaranteed perfect match to every finish
  • Finishes that change colour from one area to another

If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer.
