Facade sealing across Seton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing in Seton, done properly

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you’re dealing with draughts around frames and panels and new sealant peeling off old mastic, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Seton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction around smaller Scottish places like Seton is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Facade sealing around Seton: points for this area

The sea is no more than about 1 mile from Seton. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. In Seton, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. Our job is to seal to that specification.

Historic houses such as Hamilton House, 1.3 miles west of Seton, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Units on estates such as Whin Park Industrial Estate, 1.2 miles north-west of Seton, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Seton is about 4 miles east of Musselburgh, in East Lothian. We cover commercial sites throughout Seton, for single jobs and planned programmes alike. We work across 48 places in East Lothian, from busy centres to rural villages. Edinburgh is covered too, around 10 miles from Seton.

If you need facade sealing in EH32, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Springdale Road, Greendykes Way and Princes Way, and sites on any of them can send details for a fixed quote. If your building is just outside Seton, we cover Tranent (1 mile south), Cockenzie and Port Seton (1 mile north), Prestonpans (1 mile west), Macmerry (2 miles south-east) and Prestongrange (2 miles west). A short drive away, we cover Musselburgh (4 miles west), Haddington (6 miles east), North Berwick (11 miles north-east), Wallyford (3 miles south-west), Gullane (7 miles north-east) and East Linton (11 miles east).

How the quote is worked out

These are the things that shape the price:

  • The size and state of each joint
  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • How much there is to seal

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them

For a fixed quote, speak to us on 01277 525 020 or email the details over. You can also send details through our quote form.

Why act early in Seton

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Renewing every failing joint on one visit is the sensible approach for a place like Seton. Photos of each area help us quote the whole job.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • Workmanship guaranteed for 12 months
  • Colours confirmed for the specified product
  • Fixed quotes based on photographs, drawings or a visit

Your questions answered

Is Whin Park Industrial Estate, near Seton, within your area?

Yes. We cover Seton and the area around it, including industrial estates, business parks and retail parks such as Whin Park Industrial Estate. A few photographs and the unit address let us price the work.

Do you take on work at healthcare sites like Roodlands General Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Seton, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in

Related advice

What we are called out for in Seton

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

If one of these sounds familiar, it’s time for a closer look:

  • Draughts around frames and panels
  • Cladding panel joints that have opened up
  • Water coming in around window frames
  • Weathered facade joints that have lost their grip

When a school such as Ross High School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Commercial clients in Seton

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Surface by surface

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex as the frame moves.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone.
