Need commercial sealant contractors in Ninewells?

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

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • A failed roof covering or waterproofing membrane
  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.

Where we work in Ninewells

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

Sealant applicators in Ninewells

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. We work on washrooms and tea points, window and door perimeters and kitchen worktops and splashbacks, and the failures we are asked to look at most are smeared sealant across finishes from a rushed job and shrunken sealant along kitchen worktops and splashbacks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ninewells is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

We price commercial jobs in Ninewells from photos, drawings or a site visit, and the scope is set out in writing.

Much of the older commercial stock in Scotland’s cities is sandstone or, in Aberdeen, granite. Sealing against stone means a neutral-cure sealant that leaves the stone unmarked and, where the joint is seen, a colour that blends.

A 12-month guarantee applies to all our work in Dundee. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we will come back to it.

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For premises in Ninewells, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand

Commercial clients in Ninewells

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What we’re called out for in Ninewells

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.

Things that usually lead to an enquiry:

  • Movement joints packed with grit and debris
  • Weathered facade sealant that no longer flexes
  • Mouldy silicone around WCs, urinals and vanity tops
  • A top-up bead over failed sealant, now lifting

Sites a few miles apart, such as Dundee Technology Park and Wester Gourdie Industrial Estate, can share one programme and one point of contact.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Their plan for phasing and protecting the area
  • Health and safety accreditation such as CHAS
  • Their approach to joint depth and backing

How to choose a sealant contractor

Common questions from Ninewells clients

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

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Must a hotel around Ninewells close while you work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How do we get a quote?

Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed.

Do you cover Ninewells?

Yes. We take on work across Ninewells, and the same phone number covers every area.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Why act early in Ninewells

Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation, because that’s what makes the new bead last. Scottish city buildings take plenty of rain, and failed external joints let it into stone walls and around frames. Renewing them early protects the fabric.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • Failed material removed, not covered up
  • Health and safety: CHAS accredited
  • Constructionline member
  • Products installed to the manufacturer’s instructions

Take a look at what affects the cost and our accreditations and insurance.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • The product specified
  • Site requirements such as inductions and permits

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • What the building is and how it’s used
  • The product your specification calls for

Sealant on show in Ninewells’s commercial buildings

The sea is no more than about 1 mile from Ninewells. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Ninewells has a number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.

A hotel such as Best Western Invercarse Hotel (to the south-east of Ninewells) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Offices and shops close to stations such as Invergowrie station (0.9 miles south-west of Ninewells) tend to be busy all day, so sealant work is planned around opening hours.

Ninewells is about 2 miles west of Dundee, in Dundee. Anywhere in DD2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Dundee coverage takes in 28 places.
