About our mastic sealing in Stow

For blocks and buildings in Stow and across the Scottish Borders, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve window mastic that has split and shrunk and old repairs sealed over failed mastic, across external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in Stow tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For buildings around Stow, we group the work to keep travel and visits down. Send addresses and photographs for a quote covering the batch.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Stow can form part of a wider programme.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Failed window or door frames, which need a window contractor
  • Misted or failed double-glazed units
  • Masonry that has broken away beside the joint

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

What we seal

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

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What sets the cost

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

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • The product specified

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • The site address and postcode
  • When you need the work done

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Mastic sealing in Stow: the local picture

Being in the east of Scotland, Stow 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

Buildings close to stations like Stow station (less than half a mile west of Stow) are often flats over shops, with frame mastic to keep sound.

Stow is about 6 miles north of Galashiels, in the Scottish Borders. Across the TD1 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Stow is one of 91 places we cover in the Scottish Borders. For work in that direction, see our Edinburgh page, about 22 miles away.

We cover the TD1 postcode districts for mastic joints. Streets here include Station Road, Townfoot and Galashiels Road. Sites close to Stow are covered too, including Killochyett (1 mile north-west), Fountainhall (3 miles north-west), Lauder (5 miles north-east), Clovenfords (5 miles south) and Nether Blainslie (5 miles east). Bigger towns within reach include Peebles (13 miles west), Selkirk (10 miles south), Innerleithen (9 miles south-west), Melrose (8 miles south-east), Earlston (8 miles south-east) and Langlee (6 miles south-east).

Your questions answered

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

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Do you take on block-wide or estate-wide mastic work in Stow?

Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we will give a fixed quote.

Is Stow in your area?

Yes. Stow is in our area and the rest of the Scottish Borders. For a quote, speak to us on 01277 525 020 or email us.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long will the new sealant 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.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building near Stow, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  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. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Before we start on site

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Let building users know which areas are affected

Do you need mastic sealing in Stow?

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:

  • Worn sealant at communal door frames
  • A mix of products and colours from past repairs
  • Brittle perimeter mastic across a building
  • Damp patches beside frames

Churches, halls and community buildings such as St Mary'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.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
  • What level of public liability insurance do they hold?
