Common questions from Dunbar clients

Is a smaller place like Dunbar outside your area?

No. Places such as Dunbar are covered as much as the big towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Does a coastal location like Dunbar affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What do you charge?

Each job is quoted on its own details. For yours, phone 01277 525 020 or email drawings and photos with a description of the work.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Can we approve the colour on site?

Yes. Tell us who approves colour and we will plan the sample into the programme so sign-off doesn’t hold up the work.

How we handle coloured sealant in Dunbar

Colour is often written into the specification, by RAL reference or by matching a sample. Most sealant types are made in a broad range of standard colours, and we’ll confirm the colours available for the specified product. We don’t promise an exact custom match, but we’ll show you the closest options. We work on shop-fit joinery and counters, powder-coated and anodised frames and hotel bathrooms and public areas, and the failures we’re asked to look at most are patch repairs in several different colours and dirty, discoloured joints in public areas. Most enquiries from Dunbar start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In smaller Scottish places like Dunbar, commercial buildings are often hotels, pubs, shops, schools, surgeries and farm or estate buildings put to new use. Each has kitchens, washrooms and frames that depend on sound joints.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Shops, offices and hotels in and around Dunbar

Dunbar lies within about 1 mile of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. Dunbar has a good number of hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading.

If you run a unit on an estate such as Spott Road Industrial Estate (0.5 miles south-east of Dunbar), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. For premises near Dunbar station, which lies east of Dunbar, footfall is part of the plan: work is phased so shops and offices keep trading. For a hotel such as Eden Hotel, under half a mile to the north of Dunbar, the colour of a joint at the bar or the bath matters to the look of the room.

Dunbar is about 26 miles east of Kirkcaldy, in East Lothian. Businesses, contractors and managing agents in Dunbar can call on us for colour-matched joints. Our East Lothian coverage takes in 48 places, large and small. There’s a separate page for Edinburgh, roughly 27 miles from Dunbar.

Postcode districts covered here: EH42 for colour-matched joints. For a building on High Street, Bruntsfield Crescent and Leslie Way or nearby, send details and we’ll quote for colour-matched joints. You will find Dunbar on or near the A1087. We also cover Belhaven (1 mile west), Broxburn (1 mile south-east), West Barns (1 mile west), Bielside (1 mile west) and Spott (2 miles south). Nearby towns on our patch include Haddington (11 miles west), North Berwick (9 miles north-west), Longniddry (15 miles west), Gullane (12 miles west), East Linton (5 miles west) and Aberlady (13 miles west). As one of the bigger centres in East Lothian, Dunbar has a broad mix of commercial, public and industrial buildings.

When something else is needed

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

  • Stopping sealant from ever changing colour outdoors
  • Restoring stained stone or masonry next to old sealant
  • Paint over sealant on joints that move too much

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

Where we work in Dunbar

  • Powder-coated and anodised frames

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and we clear our waste as we work. Jobs near Dunbar are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  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. We remove the masking and walk the finished joints with you.

Preparing the site

  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs

What the job involves on each surface

Paintable sealants

Some joints are better sealed with a paintable product and decorated. It depends on movement and the specification because paint may crack where the joint moves.

Brick and masonry

Movement joints in brickwork are long and visible. A well-chosen colour helps them blend in while the product still suits the movement.

Why act early in Dunbar

Resealing a full run gives a consistent colour. Small repairs at different times rarely match, and the patchwork effect grows. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Dunbar before they leak.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

What you get with us

  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product
  • Commercial sealant work since 2005
  • Our applicators hold CSCS cards

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Dunbar can form part of a wider programme.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
