Common questions from Nisbet clients

Does your area include sites such as Station Industrial Estate, near Nisbet?

Yes, sites like Station Industrial Estate are within our area, along with the rest of Nisbet. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is a smaller place like Nisbet outside your area?

Not at all. Nisbet is within our area. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.

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.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Can you seal external joints in wet or cold weather?

Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.

What guarantee comes with a mastic package?

It’s backed by our 12-month guarantee, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Construction mastic in Nisbet, done properly

Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list. We seal so the snag list stays short, whatever the size of the scheme. Site teams most often ask us about early adhesion failures on new external joints and old sealant on a refurbishment that needs stripping before new work, across cladding and panel joints, internal decorators’ caulk and window and door perimeters. Facilities teams, main contractors and managing agents in Nisbet tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites near smaller places like Nisbet can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Honest limits

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

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Approving fire stopping as compliant
  • Specifying the product where the designer hasn’t

If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in Nisbet

  • Internal decorators’ caulk
  • Sanitary and kitchen joints

  • Floor and skirting junctions
  • Window and door perimeters
  • Cladding and panel joints

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a building near Nisbet, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

What we need from you

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Signs you need construction mastic in Nisbet

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.

Any of the following is a good reason to get the joints checked over:

  • Oversized or tapered gaps around new frames
  • Old sealant on a refurbishment that needs stripping before new work
  • Cracks opening in caulked internal joints
  • New external sealant already peeling away

Recladding or extending a unit at a site like Station Industrial Estate, 2.7 miles to the south-west of Nisbet, brings panel joints and frame perimeters into the programme.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Will RAMS and insurance details be available?
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

What affects the price in Nisbet

Before we quote, we look at:

  • How much existing material needs removing
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

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’ll explain how it’s made up.

Sending details for a quote

We can often quote from photos and a few details. Please tell us:

  • When you need the work done
  • How the joints are reached, and at what height
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, call 01277 525 020 or email us.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Aftercare for building managers

After handover, these steps help:

  • Keep product details for future maintenance
  • Flag uneven or tapered frame gaps early
  • Ask cleaners to use soft cloths around fresh sealant
  • Get the mastic subcontractor involved early in the programme

After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.

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