Facade sealing near Preston

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems
  • Providing access systems for the work

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Preston

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

Facade sealing in Preston

Every facade quote starts with how the joints will be reached. 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. The enquiries we see most involve air leaks through failed facade joints and water coming in around window frames, on window and door perimeters, coping and flashing joints and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Preston, that means joint design, primers and backing rod as standard.

For a site around Preston, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.

Work we carry out in East Lothian comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or use the quote form and we’ll come back to it.

How the job changes by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

New build and refits around Preston

Preston sits close to the coast, within about 3 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. A number of hotels sit less than 2 miles from Preston. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

For a contractor at a hotel such as Harvesters Hotel, 0.6 miles to the south-west of Preston, the mastic often has to be finished before a reopening date.

Preston is about 5 miles west of Dunbar, in East Lothian. If you are looking for facade sealing in Preston, we can help. 48 places across East Lothian fall within our area, Preston among them. We also cover Edinburgh, around 22 miles from Preston.

Work on facade joints is covered throughout EH40, for business premises of every kind. If your building is just outside Preston, we cover Phantassie (1 mile south), Smeaton (1 mile north-west), East Linton (1 mile south-west), Stenton (3 miles south-east) and Garvald (4 miles south). Further afield, our area takes in Haddington (6 miles south-west), Dunbar (5 miles east), Tranent (12 miles west), North Berwick (5 miles north-west), Prestonpans (13 miles west) and Cockenzie and Port Seton (12 miles west).

Around Preston

We work on buildings around The Crown & Kitchen pub and the streets around them. The nearest railway station is East Linton station, about 0.7 miles south-west of the centre. Nearby you will also find Hailes Castle (2 miles south-west) and National Museum of Flight (2.7 miles west). For a walk, there’s Traprain Law.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

How the quote is worked out

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Whether old sealant has to be cut out first
  • The product specified

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • The product your specification calls for
  • The site address and postcode

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 a schedule or drawings.

Signs you need facade sealing in Preston

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

If one of these sounds familiar, it’s time for a closer look:

  • Perimeter joints where frames meet the structure
  • Cold air coming in at window perimeters
  • Cladding panel joints that have opened up
  • New sealant peeling off old mastic

On a healthcare site such as Belhaven Hospital, which lies east of Preston, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with

How to choose a sealant contractor

Questions about Preston

Is a hospital such as Belhaven Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Preston too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, so we plan around the forecast.

What do you charge?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Preston is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Flag any permit to work we will need
  • Send your site hours and access windows
  • Share the asbestos register for older buildings
