About our facade sealing in Seamill

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints, and the usual reasons a site gets in touch are patch repairs that keep failing and cladding panel joints that have opened up. Most enquiries from Seamill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Seamill that means watching the forecast. We build some give into the plan and agree it with the site manager.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Seamill, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We plan access and the order of elevations with the client.
  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. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Let building users know which areas are affected

Related advice

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Plan facade sealing alongside redecoration
  • Brief window cleaners about newly sealed joints
  • Investigate damp beside windows promptly
  • Confirm the survey covers external sealants in older buildings

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

What affects the price in Seamill

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Location, for remote and island sites

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

A few photos plus some basic facts will normally do. It helps to include:

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Facade sealing around Seamill: points for this area

Seamill is within about 1 mile of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Seamill is in the west of Scotland, the wetter side of the country. We keep internal mastic in hand so wet days aren’t lost.

Hospital estates such as Lady Margaret Hospital (to the north of Seamill) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Hotel extensions and refits, at places such as Seamill House Hotel, which lies north-east of Seamill, typically run between busy periods, so the sealing is squeezed into short windows.

Seamill is about 3 miles north-west of Ardrossan, in North Ayrshire. Businesses, contractors and managing agents in Seamill can call on us for facade joints. Across North Ayrshire, 54 places are covered, Seamill among them. Sites around Glasgow have their own page, about 26 miles away.

Your questions answered

Would you work within a site like Lady Margaret Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Our building in Seamill is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

How the job changes by surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in, tooled to shed water.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign
  • Render or concrete edges that have broken away

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.

What we seal

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