Facade sealing near Dalkeith

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Several buildings in and around Dalkeith can be done on one programme, with one quote. Give us access times for each.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

How we handle facade sealing in Dalkeith

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. If you’re dealing with weathered joints at frame-to-structure perimeters and air leaks through failed facade joints, we can help. Looking for mastic applicators who cover Dalkeith? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Main contractors and developers in towns like Dalkeith work to Scotland’s building standards, with warrants from the local authority. We seal to the specification and the programme, and clear snags before completion.

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.

Building and refurbishing in Dalkeith

The area within 2 miles of Dalkeith holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Dalkeith is on Scotland’s drier eastern side. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External mastic is planned with the site manager for workable conditions.

For contractors at a college like Newbattle Abbey College, 0.6 miles to the south of Dalkeith, perimeters and internal sealant are timed for the holidays. When units on a site such as Hardengreen Business Park (to the south-west of Dalkeith) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Dalkeith is about 7 miles south-east of Edinburgh, in Midlothian. Dalkeith sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Midlothian, 34 places are covered, Dalkeith among them. Sites around Edinburgh have their own page, roughly 7 miles from Dalkeith.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Damp caused by condensation inside the building
  • Damaged frames that need replacing
  • Joints whose design needs changing by the specifier

Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly.

What we seal

  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Cladding panel joints
  • Shopfront frames
  • Window and door perimeters

Cost factors for facade joints

To price the job, we consider:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Access and working height
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • Any specification or named product

To get a fixed quote, call the office on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Building owners and managing agents use us on everything from one building to a spread of sites around Dalkeith. One quote can cover more than one site, which keeps the paperwork simple.

Surface by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Common questions from Dalkeith clients

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

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you cover business parks and estates near Dalkeith, such as Hardengreen Business Park?

Yes. Estates, retail parks and business parks around Dalkeith, Hardengreen Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Do you replace windows or glass?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you cover Dalkeith?

Yes. We cover Dalkeith, and the simplest way to start is to ring 01277 525 020 or email us.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

When to call us in Dalkeith

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

Site and facilities staff are often the first to spot these:

  • Patch repairs that keep failing
  • Unsightly perimeter sealant on a visible elevation
  • Facade joints cracked through the middle
  • Gaps between rainscreen or cladding panels

For a contractor at a hotel such as Cross Keys Hotel, less than half a mile north-west of Dalkeith, the mastic often has to be finished before a reopening date.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • Will CSCS-carded applicators be on site?
