About our mastic sealing in Peterhead

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you have communal area joints that look neglected and damp patches beside frames, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Peterhead, that means joint design, primers and backing rod as standard.

Owners with several buildings in a town like Peterhead can group mastic work into one programme. Residents are kept informed through the factor or landlord as work moves between buildings.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. 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.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How the job changes by surface

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.

Why it’s worth doing now in Peterhead

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Water through a failed joint in a building in Peterhead can spoil ceilings, floors and stock. Putting it right early limits the damage.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Peterhead: questions and answers

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

Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.

Is Blackhouse Industrial Estate, near Peterhead, within your area?

Yes. We cover Peterhead and the area around it, including industrial estates, business parks and retail parks such as Blackhouse Industrial Estate. Photos and a short description are enough for a first look.

How many days will you need on site?

It depends on the scope, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Do you cover Peterhead?

Yes. We cover Peterhead and the rest of Aberdeenshire. To discuss a job, call 01277 525 020 or email a schedule or drawings.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

For owners and agents in Peterhead

The sea is no more than about 1 mile from Peterhead. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. The east of Scotland, where Peterhead is, gets less rain than the west. Outside mastic still waits for dry, frost-clear conditions. We plan block programmes with some give for it

For owners of several units at places like Blackhouse Industrial Estate (0.6 miles north-west of Peterhead), one programme can deal with frame and external mastic across the lot.

Peterhead is about 27 miles north-east of Aberdeen, in Aberdeenshire. We cover Peterhead, with the same fixed quotes and 12-month guarantee as everywhere else. Peterhead is one of 179 places we cover in Aberdeenshire. Our Aberdeen page has more on work in that area, about 27 miles away.

Commercial sites across AB42 are covered. Streets here include Station Road, High Street and Grange Gardens, and sites on any of them can send details for a fixed quote. Peterhead sits on or close to the A90 and A950, useful when we plan access and materials. Nearby places we also cover include Clerkhill (1 mile south), Buchanhaven (1 mile north), Roanheads (1 mile east), Port Henry (1 mile east) and Inverugie (1 mile north-west). Further afield, our area takes in Fraserburgh (15 miles north-west), Ellon (14 miles south-west), Mintlaw (8 miles west), Broadsea (15 miles north-west), Cruden Bay (6 miles south) and Inverallochy (13 miles north-west). Among the larger centres in Aberdeenshire is Peterhead, and its commercial and public buildings are all within our area.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Industrial estates and retail parks around towns like Peterhead usually have yard space and site rules. Town-centre premises may need parking planned.

  1. First we look at the mastic on each building and note what needs replacing.
  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. Old sealant is stripped and each face prepared back to firm material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed 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
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Related advice

Signs you need mastic sealing in Peterhead

Buildings move with temperature and moisture, 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.

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

  • The same joint failures repeated across a portfolio
  • Damaged joints in communal entrances and corridors
  • Repeated reactive repairs to the same buildings
  • Brittle perimeter mastic across a building

For owners and agents with buildings in or around Peterhead, block-wide mastic programmes deal with frames and external joints of the same age together.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Masonry that has broken away beside the joint
  • Asbestos-containing sealant, which we don’t remove
  • Leaks from above rather than through a joint

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

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