About our mastic sealing in Birkenside

Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Most enquiries involve estate-wide sealant that is simply worn out and movement joints with sealant missing, on communal entrances and stairwells, communal kitchens and washrooms and window and door perimeters on blocks. Searching for sealant specialists in Birkenside? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places such as Birkenside, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic typically fails first.

A 12-month guarantee applies to all our work in Midlothian. Should something we installed fail, speak to us on 01277 525 020 or email us and we will come back to it.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Keep bins and bikes away from communal door frames
  • Ask residents or tenants to report leaks and draughts early
  • Mention RAMS, insurance or CSCS requirements up front
  • Include mastic in your cyclical inspections

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs near Birkenside are often grouped with others in the same area. Let us know if your dates have any give.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • Move anything stored against the joints

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email drawings and photos with what you know.

Advice

What the job involves on each surface

Commercial and mixed-use buildings

Commercial occupiers usually stay open during the work so the work is phased.

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Birkenside: questions and answers

Will you take on work at estates like Butlerfield Industrial Estate, close to Birkenside?

Yes. Our area takes in Birkenside and its surroundings, with estates and business parks such as Butlerfield Industrial Estate included. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Can you quote for a block close to Gorebridge station?

Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

What about access for upper-floor joints?

Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you need mastic sealing in Birkenside?

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

These are often picked up first by site or facilities staff:

  • Worn sealant at communal door frames
  • Damp patches beside frames
  • Failed external movement joints
  • Draughts at frames across a block

Older community buildings, Hunterfield Road Church among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • The named product and why it was chosen
  • Will failed sealant be removed rather than covered?
  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long

Why act early in Birkenside

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. Around smaller places like Birkenside, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • 12 months’ guarantee on every job
  • A range of standard colours, depending on the product
  • A fixed quote before work starts
  • Joints cleaned back to sound surfaces

  • The product your specification calls for
  • A wide shot and a close-up of the area
