Advice

How we handle mastic sealing in Dalton

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. Site teams most often ask us about draught complaints from residents or tenants and communal area joints that look neglected, across balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Dalton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Work we carry out in South Lanarkshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we will arrange a return visit.

What affects the price in Dalton

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether old sealant has to be cut out first
  • Access and working height
  • Travel to remote or island sites
  • The site’s rules and procedures

Pricing mastic joints depends on quantities, condition and access. Call for a quote.

Sending details for a quote

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

  • Access details, including height
  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • The postcode of the building

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Looking after buildings in and around Dalton

There are three care or nursing homes within about 2 miles of Dalton. Care home owners need frame and external mastic kept sound without unsettling residents. The west of Scotland, where Dalton is, gets more rain than the east. Frame mastic on weather-facing sides tends to fail first. Programmes allow for wet days.

For a school such as High Blantyre Primary, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like Priestfield Industrial Estate (2 miles south-east of Dalton), one programme can deal with frame and external mastic across the lot.

Dalton is about 1 mile north-west of Blantyre, in South Lanarkshire. Across the G72 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Dalton is one of 134 places in South Lanarkshire on our list. For work in that direction, see our Glasgow page, about 7 miles away.

Commercial sites across G72 are covered. With the A724 nearby, Dalton is easy to get to with materials and equipment. Nearby places we also cover include Flemington (1 mile north-west), Newton (1 mile north), Cairns (1 mile north-west), Cambuslang (1 mile north-west) and Greenlees (1 mile west) for mastic joints. A short drive away, we cover East Kilbride (4 miles south-west), Hamilton (3 miles south-east), Larkhall (8 miles south-east), Carluke (12 miles south-east), Rutherglen (4 miles west) and Strathaven (9 miles south).

Looking after the joints

To get the most from the new sealant:

  • Make it easy for occupiers to report draughts
  • Prioritise elevations facing the weather
  • Share the asbestos register when you send details
  • Include mastic in your cyclical inspections

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.

When to call us in Dalton

Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.

Things that typically lead to an enquiry:

  • A mix of products and colours from past repairs
  • Mastic failing across several blocks on an estate
  • Leaks at window and door perimeters
  • Occupiers reporting cold air round windows

Blocks of flats and mixed-use buildings often cluster around stations such as Newton station, 1.1 miles north-west of Dalton, and their window and balcony mastic tends to age at the same rate across a building.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Are they CHAS accredited or on Constructionline?
  • The named product and why it was chosen
  • Can the work be phased to keep areas open?

Our contractor checklist

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Questions about Dalton

Will you take on a block within reach of Newton station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Can you work in a care home near Dalton with residents in?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long do sealant joints last?

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

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
