Mastic sealing in Throsk

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Building owners, agents and FMs in Throsk

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Mastic sealing for commercial buildings in Throsk

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. Site teams most often ask us about communal area joints that look neglected and estate-wide sealant that is simply worn out, across communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Throsk, preparation and product choice get the time they need.

In smaller Scottish places like Throsk, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic typically fails first.

Work we carry out in Stirling comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

Do you need mastic sealing in Throsk?

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

It’s worth sending us details if you spot any of the following:

  • Cracked, hardened mastic round windows on a block
  • Draught complaints from residents or tenants
  • A mix of products and colours from past repairs
  • Damaged joints in communal entrances and corridors

Buildings close to stations like Alloa station, 2.6 miles north-east of Throsk, are often flats over shops, with frame mastic to keep sound.

Choosing a commercial sealant contractor

Why deal with it now?

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why clients in Throsk choose us

  • Old sealant cut out, never sealed over
  • Coloured sealants to suit the setting, where available
  • Fully insured, including public liability cover
  • Colours confirmed for the specified product

Common questions from Throsk clients

Can you quote for a block close to Alloa station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Does a coastal location like Throsk affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you do block-wide mastic programmes?

Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs near Throsk are often grouped with others in the same area. Tell us how flexible your dates are.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Point out any areas we must not close
  • Tell staff and tenants when we will be in
  • Send asbestos survey details if the building is pre-2000

After the work

Once the work is signed off, these steps help:

  • Make it easy for occupiers to report draughts
  • Start inspections with the most exposed faces
  • Have the asbestos survey to hand for older buildings
  • Keep a record of when each building was resealed

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Different surfaces, different methods

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.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Looking after buildings in and around Throsk

Throsk is within about 1 mile of the coast. On buildings near the shore, the side facing the weather normally needs its mastic renewed first, so it’s worth inspecting those sides more often. The east of Scotland, where Throsk is, gets less rain than the west. Outside mastic still waits for dry, frost-clear conditions. Programmes allow for that

For a school such as Alloa Academy, perimeter mastic on windows and doors is a holiday job. Student blocks close to universities like University of Stirling (4.3 miles north-west of Throsk) are easiest to work on between tenancies.

Throsk is about 3 miles south-west of Alloa, in Stirling. We cover commercial sites throughout Throsk, whether it’s a single job or part of a planned programme. We work across 52 places in Stirling, large and small. For work in that direction, see our Glasgow page, about 24 miles away.
