Need mastic sealing in Castledykes?

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

Mastic sealing in Castledykes, done properly

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you’re dealing with draught complaints from residents or tenants and worn sealant at communal door frames, we can put it right, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints alike. Most enquiries from Castledykes start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For buildings around Castledykes, we group the work to keep travel and visits down. Send addresses and photos for a quote covering the batch.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What affects the price in Castledykes

To price the job, we consider:

  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • Working within restricted access windows

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The site address and postcode
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • The type of building and who uses it

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites around Castledykes. Several sites can go on one quote, so there’s one set of paperwork to deal with.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Surface by surface

Communal areas

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.

Common questions from Castledykes clients

Does your area include sites such as St. Mary's Industrial Estate, near Castledykes?

Yes, sites like St. Mary's Industrial Estate are within our area, along with the rest of Castledykes. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Castledykes too far out for you?

Not at all. Castledykes is within our area. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is any job too small?

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.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Why it’s worth doing now in Castledykes

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Castledykes before they leak.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • CSCS-carded applicators
  • A range of standard colours, depending on the product
  • Matching to RAL references, product permitting
  • One contact handling all your sites

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. For work around Castledykes, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Related advice

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
