Commercial sealant contractors for businesses in Ardler

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

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep abrasive pads and scrapers off resealed joints
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Note dates and locations of sealant work for future planning
  • Put external and wet-area joints on a regular inspection round

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just phone 01277 525 020 or use the quote form for a quote.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.

Sealant specialists in Ardler

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Ardler, the quickest start is to give us a call on 01277 525 020 or email a schedule or drawings with a list of addresses. We work on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints, and what we’re called in for most is water staining near frames, panels or ceilings and hardened, chalky sealant on south-facing or exposed elevations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ardler, that means joint design, primers and backing rod as standard.

Quotes for commercial sealant in Ardler can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

In Scotland’s cities, commercial premises are packed closely, from stone-fronted offices to shops on the ground floor of tenement blocks. Where a shop sits below tenement flats, work on the frontage or shared parts may involve the property factor.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Old mastic that tests positive for asbestos
  • Water from a services leak rather than a joint
  • Broken glass or blown double-glazed units

If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Where we work in Ardler

  • External facade joints
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • Washrooms and tea points
  • Kitchen worktops and splashbacks

What affects the price in Ardler

We price every job individually. The things that drive the figure:

  • Joint width, depth and condition
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email drawings and photos.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Give us the access times and building rules for your premises in Ardler, so the work can be phased and areas kept in use.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.

Common questions from Ardler clients

Does a hotel in Ardler need to shut while its sealant is renewed?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Our building in Ardler is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you check for asbestos before removing sealant?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

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, since fresh sealant will not bond reliably to aged material.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Sealant on show in Ardler’s commercial buildings

Ardler is within about 3 miles of the coast. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Sea-facing elevations are normally where failed joints show first. Ardler has seven care or nursing homes no more than 2 miles away. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean.

Shops and cafés around stations like Invergowrie station (to the south-west of Ardler) trade from early, so work is timed around them. Occupiers with premises at both Dryburgh Industrial Estate and Dovercourt Commercial Park could have the sealant at each handled under one quote. Shopping centres and retail parks such as Kingsway West Retail Park, 0.9 miles south-east of Ardler, see a steady turnover of shop fits, each leaving joints where colour and finish matter.

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Ardler can sit alongside others in a wider programme across Dundee.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
