Mastic sealing for commercial buildings in Dunning

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are open joints in brickwork or panels and cracked, hardened mastic round windows on a block. For commercial sealant work in Dunning, you deal with one contact from quote to sign-off, whether it’s one building or several.

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

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we are called out for in Dunning

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

Clients typically get in touch after noticing one or more of the following:

  • A mix of products and colours from past repairs
  • Cracked, hardened mastic round windows on a block
  • Repeated reactive repairs to the same buildings
  • Damp patches beside frames

Churches, halls and community buildings such as St Serf's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply
  • Their pre-qualification and accreditations

Cost factors for mastic joints

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Any access equipment needed
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • How much there is to seal

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • The product your specification calls for
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • Asbestos survey details if the building is older

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or send photos by email to discuss it first.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Check the asbestos register before any old mastic is disturbed
  • Encourage occupiers to report problems at frames
  • Group repairs into a planned programme
  • List the paperwork your organisation requires when you send details

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

From enquiry to sign-off

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. Where we can, we combine work around Dunning with other jobs nearby. Let us know if your dates have any give.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Let us know about inductions and permits

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Water coming in from the roof or rainwater goods
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Frames that are rotten, warped or broken

If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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