For owners and agents in Blackford

Being in the east of Scotland, Blackford gets less rain than the west coast. Cold mornings still limit when outside mastic can go on. Block programmes are built with that in mind

How we handle mastic sealing in Blackford

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Most enquiries involve a mix of products and colours from past repairs and worn sealant at communal door frames, across window and door perimeters on blocks, shopfronts below residential blocks and communal entrances and stairwells. A single leaking joint is often how a building in Blackford first comes to us: we look at the rest while we are there and tell you what we find.

Outside mastic in Scotland needs dry joints and the right temperature, so work around Blackford is planned with the forecast. Programmes allow for the weather.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Questions we’re asked in Blackford

We manage a building near Gleneagles station. Can you help?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Can one quote cover a number of our buildings near Blackford?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Can you take on resealing for a block portfolio?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking one or more days per building, depending on the joint lengths and the access. Jobs near Blackford 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 look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use

Quotes

Leave it or put it right?

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Blackford, a repair visit takes planning, so it’s better to act early.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • RAL and finish matching where the product range allows
  • Public liability insurance in place
  • CSCS-carded applicators
  • Old sealant cut out, never sealed over

Take a look at what affects the cost and our accreditations and insurance.

When to call us in Blackford

Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.

Typical triggers for a call:

  • The same joint failures repeated across a portfolio
  • Window mastic that has split and shrunk
  • Draughts at frames across a block
  • Open joints in brickwork or panels

For agents with blocks near Gleneagles station, 2.2 miles to the north-east of Blackford, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Misted or failed double-glazed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Masonry that has broken away beside the joint

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Joints and surfaces we work on

  • Balcony and threshold joints
  • Shopfronts below residential blocks
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • External wall and movement joints
  • Communal entrances and stairwells

What the job involves on each surface

Communal areas

Low-level communal joints get damaged more than most and tend to fail first.

Tenement and older buildings

Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
