Coloured sealant for commercial buildings in Duddleswell

In retail, hospitality and office fit-outs, joints are seen close up every day. 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. We work on cladding panels, shop-fit joinery and counters and natural stone and brick, and the failures we’re asked to look at most are old sealant that has yellowed, darkened or faded and colour changes after a rebrand or refit. Searching for sealant specialists in Duddleswell? We have been sealing commercial buildings since 2005.

Work in smaller places such as Duddleswell tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

  • Coloured joints that have cracked with movement
  • Discoloured joints on a visible elevation

FAQs: Duddleswell

What paperwork can you provide for a job in Duddleswell?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can the sealant on our Duddleswell premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we will confirm what’s available for the product.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Duddleswell, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  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.

Before we start on site

  • Let building users know which areas are affected
  • Arrange parking or a loading space
  • Point out any areas we must not close

Quotes

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or send details through our quote form.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Keep the area clear while the sealant cures
  • Put the colour reference on the finishes schedule
  • Check a trial length in real light
  • Insist on the agreed colour for any repair

Give the sealant its full cure time before cleaning or handling the area. Fresh coloured beads show fingerprints and dust more easily, so keep the area clear.

Plan resealing of visible joints before they look tired. Replacing them on a schedule keeps finishes looking right over the years.
