Facade sealing near Langlee

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Replacing glass or failed glazing units
  • Arranging specialist high-level access, which is planned with the client

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

Facade sealing in Langlee, done properly

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. We work on cladding panel joints, stone and brick facade joints and shopfront frames, and what we are called in for most is water coming in around window frames and staining on stone next to old sealant. For commercial sealant work in Langlee, you deal with one contact from quote to sign-off, whether it’s one building or several.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Langlee that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Owners, agents and contractors

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. We can agree access arrangements and keyholder contacts beforehand.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

What sets the cost

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

  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Access and working height

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.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

What happens if it’s left?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Langlee, a repair visit takes planning, so it’s better to act early.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What you get with us

  • Specification-led, product-correct work
  • Constructionline member for supplier checks
  • Coloured sealants to suit the setting, where available
  • One number for every site we cover

Take a look at our cost guide or our accreditations.

What we are called out for in Langlee

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.

Clients usually get in touch after noticing one or more of the following:

  • Draughts around frames and panels
  • Damp patches beside frames after rain
  • Gaps between rainscreen or cladding panels
  • Sealant pulling away from frames or panels

Hotel extensions and refits, at places such as Kingsknowes Hotel, 0.6 miles to the south of Langlee, normally run between busy periods, so the sealing is squeezed into short windows.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

Langlee: questions and answers

Is Langlee off your patch?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like Heriot-Watt University - Scottish Borders Campus for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Do you replace windows or glass?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels across the facade.

Do you provide access for facade work?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details.

New build and refits around Langlee

The area within 2 miles of Langlee holds a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The east of Scotland, where Langlee is, gets less rain than the west. Frosty spells still affect external mastic dates. External mastic is planned with the site manager for workable conditions.

On a healthcare site such as Borders General Hospital, 1.8 miles south-east of Langlee, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors refurbishing units at places like Netherdale Industrial Estate, which lies south-west of Langlee, the mastic covers cladding panels, roller-door and window perimeters.

Langlee is about 1 mile east of Galashiels, in the Scottish Borders. Across the TD1 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our the Scottish Borders coverage takes in 91 places, from busy centres to rural villages. For work in that direction, see our Edinburgh page.

Work on facade joints is covered throughout TD1 and TD6. We cover commercial and managed buildings on Tweed Road, Brier Lane and Gorse Lane and the roads nearby.

If your building is just outside Langlee, we cover Tweedbank (1 mile south-east), Galashiels (1 mile west), Boleside (2 miles south-west), Darnick (2 miles south-east) and Gattonside (2 miles east).

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs near Langlee are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  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.

Preparing the site

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
