Questions we are asked in Douglas

Will you plan work around the academic year at somewhere like Abertay University?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Does your area include sites such as Baldovie Industrial Estate, near Douglas?

Yes. We cover Douglas and the area around it, including industrial estates, business parks and retail parks such as Baldovie Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Is Douglas in your area?

Yes. We cover Douglas, and you can call the office on 01277 525 020 or email the details over to get started.

Will you just go over the old sealant?

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.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Facade sealing in Douglas

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Douglas. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with previous reseals run over old sealant and water coming in around window frames, we can help, whatever the surface. A single leaking joint is often how a building in Douglas first comes to us: we look at the rest while we are there and tell you what we find.

Sandstone and, in Aberdeen, granite buildings need care when new windows or panels are sealed against them: the right primer, a neutral-cure sealant and a colour that blends.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • How much existing material needs removing
  • Phasing around occupants

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • What the building is and how it’s used
  • The product your specification calls for

To get a fixed quote, speak to us on 01277 525 020 or use the quote form with the site address and an outline of the work. Our quote form is another easy route.

How a job runs

Site rules come first: 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 premises in Douglas, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Leave it or put it right?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Fixing it promptly keeps repairs small.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why us?

  • Sealing commercial buildings since 2005
  • Colour agreed before work starts
  • One phone line for London, the South East and Scotland
  • Workmanship guaranteed for 12 months

Common problems we fix in Douglas

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Most enquiries start with one or more of the following:

  • Hard, chalky sealant that no longer flexes
  • Unsightly perimeter sealant on a visible elevation
  • New sealant peeling off old mastic
  • Facade joints cracked through the middle

When units on a site such as Baldovie Industrial Estate, 0.5 miles north-east of Douglas, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Their public liability cover
  • Whether primer will be used where the manufacturer specifies it
  • The named product and why it was chosen

How to choose a sealant contractor

Building and refurbishing in Douglas

Douglas sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Douglas is in the east of Scotland, which is drier than the west. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team.

Projects at colleges like Dundee and Angus College - Gardyne Campus, 0.5 miles south-west of Douglas, tend to run to term dates, so the mastic is planned tightly. For contractors on a campus like Abertay University, 2.8 miles to the west of Douglas, facade and perimeter sealing has to fit around students and term dates.

Douglas is about 2 miles west of Broughty Ferry, in Dundee. Anywhere in DD4, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 28 places across Dundee fall within our area, including Douglas.

Surface by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier
  • Cracked or spalling substrates that need repair before sealing

If you are not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.
