Mastic sealing across Inverness

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Check the asbestos register before any old mastic is disturbed
  • Share your contractor requirements early
  • Ask residents or tenants to report leaks and draughts early
  • Keep bins and bikes away from communal door frames

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.

Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.

How we handle mastic sealing in Inverness

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and movement joints with sealant missing. A specialist sealant contractor works differently from a general builder: on jobs in Inverness, preparation and product choice get the time they need.

Owners with several buildings in a town like Inverness can group mastic work into one programme. We move block by block once you’ve told residents what to expect.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. Jobs in Inverness are planned with two things in mind: the forecast for external joints and the building’s hours for internal ones. Send photographs or drawings and we’ll quote and plan to suit.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Confirm the product named in the specification

Cost factors for mastic joints

The price varies from site to site. Expect it to depend on:

  • The total length or number of joints
  • The product specified
  • Access and working height
  • Distance, for remote addresses

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • When you need the work done
  • Anything awkward about access or site hours

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Common questions from Inverness clients

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

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Telford Retail Park, near Inverness, within your area?

Yes. Our area takes in Inverness and its surroundings, with estates and business parks such as Telford Retail Park included. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What do you charge?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Mastic sealing around Inverness: points for this area

With the shore within about 2 miles, Inverness counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. The west of Scotland, where Inverness is, gets more rain than the east. Frame mastic on weather-facing sides tends to fail first. External work is booked for dry spells, with a little give in the dates.

If you look after a block within reach of Inverness station, which lies north of Inverness, frame and balcony mastic can be renewed on one programme. For owners of several units at places like Telford Retail Park, 1.1 miles north-west of Inverness, one programme can deal with frame and external mastic across the lot. Site managers at schools like Inverness High School can fit frame mastic into the summer works.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Water through a failed joint in a building in Inverness can spoil ceilings, floors and stock. Early action limits what needs repairing.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us
