Construction mastic for Scottish Borders sites

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

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Frames fitted out of tolerance
  • Defective windows, doors or glazing units (the supplier or installer’s job)

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Surfaces we seal

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

Construction mastic in Scottish Borders, done properly

The specification and the programme set the job. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out. If you have missed perimeter joints on a new elevation and perimeter gaps outside the sealant’s range, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Scottish Borders is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In smaller places such as Scottish Borders, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Why act early in Scottish Borders

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility, with the same standard on every plot. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Scottish Borders before they leak.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • Workmanship guaranteed for 12 months
  • Clear, fixed quotes
  • CHAS accredited contractor
  • Commercial sealant work since 2005

What we’re called out for in Scottish Borders

A new building moves while it dries and settles. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.

Look out for the following:

  • Internal caulk splitting as the building dries out
  • Failed sealant in an existing building being refurbished
  • Inconsistent sealant finishes from plot to plot
  • Mastic snags holding up handover

For contractors building in or near Scottish Borders, we seal to the drawings, the specification and the programme.

FAQs: Scottish Borders

Is a smaller place like Scottish Borders outside your area?

No. Places such as Scottish Borders are covered as much as the big towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

What paperwork can you provide for a job in Scottish Borders?

We’ll 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.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Can you come in just for snagging?

Yes, we can. Share the list and photos, and a fixed quote follows, with the work timed to your handover date.

What accreditations do you hold?

We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Will you stick to the specified products?

The specification decides the product, and we will raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.

Cost factors for mastic packages

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • The total length or number of joints
  • The site’s rules and procedures
  • The product specified
  • Removal of failed or old sealant

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Access details, including height
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Any specification or named product

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Scottish Borders is in the east of Scotland, which is drier than the west. Cold, damp starts still stop external sealing on some days. We programme around it with the site team. In Scottish Borders, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.

A facade joint near Scottish Borders lasts when width, depth and backing are right, not just the finish.
