Construction mastic for Seton sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Signs you need construction mastic in Seton

Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.

Typical triggers for a call:

  • Different trades sealing to different standards
  • Bath and shower joints scraped during the final clean
  • Perimeter gaps outside the sealant’s range
  • Cracks opening in caulked internal joints

When units on a site such as Whin Park Industrial Estate, 1.2 miles north-west of Seton, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What your quote should include

  • The named product and why it was chosen
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

Construction mastic in Seton

Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you’re dealing with sanitary sealant damaged by following trades and mastic snags holding up handover, we can help, whatever the surface. Looking for mastic applicators who cover Seton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In smaller places such as Seton, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

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

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building near Seton, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Before we start on site

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Advice

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What happens if it’s left?

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption and saves applicators coming back again and again. We can run snagging as its own phase before handover. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Seton, a repair visit takes planning, so it’s better to act early.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • Failed material removed, not covered up
  • Fully insured, including public liability cover
  • Products installed to the manufacturer’s instructions
  • 12 months’ guarantee on every job

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Specifying the product where the designer hasn’t
  • Glazing units that are cracked or misted
  • Frame gaps too wide for sealant, which the installer needs to correct

Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

  • Internal decorators’ caulk
  • Window and door perimeters
  • Sanitary and kitchen joints
  • Floor and skirting junctions
  • Brick and block movement joints
  • Cladding and panel joints

Questions about Seton

Will you take on work at estates like Whin Park Industrial Estate, close to Seton?

Yes. Estates, retail parks and business parks around Seton, Whin Park Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is Seton too small for you to travel to?

Not at all. Seton is within our area. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How do you deal with asbestos in old sealant?

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. Removing asbestos is a job for asbestos specialists, not us.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Will you stick to the specified products?

The specified product is what goes in. If we think an alternative would suit better, we put it to you first.

Can fire-rated sealing at service penetrations be included?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we’ll confirm with the quote.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Plan external elevations with the weather in mind
  • Note which sealant went where at handover
  • Get the mastic subcontractor involved early in the programme
  • Don’t schedule sealing before decorators and flooring are done

Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.

Construction mastic in Seton: the local picture

Seton lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Projects in Seton follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.

When a school such as Ross High School is extended or refurbished, the mastic package is often squeezed into the holidays. Older buildings in the area around Seton, such as Hamilton House, which lies west of Seton, need care when sealed: the product has to suit soft or historic materials.

Seton is about 4 miles east of Musselburgh, in East Lothian. Our applicators travel to Seton for work on mastic packages. Seton is one of 48 places in East Lothian on our list for mastic packages. Sites around Edinburgh have their own page, about 10 miles away.
