Mastic sealing in Newstead

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. 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. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

About our mastic sealing in Newstead

Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the failures we are asked to look at most are cracked, hardened mastic round windows on a block and water getting in round frames after rain. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Newstead it comes down to the same thing: the right product in a properly prepared joint.

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

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

Frames, entrances and external joints in Newstead

The east of Scotland, where Newstead is, gets less rain than the west. Frost and condensation on winter mornings can still delay outside mastic.

For owners of several units at places like Tweed Horizons Business Centre, which lies south-east of Newstead, one programme can deal with frame and external mastic across the lot. For agents with blocks near Tweedbank station, 2.5 miles west of Newstead, a block-wide mastic programme deals with frames, balconies and entrances in one go. If you manage student housing near a university such as Heriot-Watt University - Scottish Borders Campus, 3.5 miles to the west of Newstead, the summer turnaround is the time for mastic.

Newstead is about 4 miles east of Galashiels, in the Scottish Borders.

What we can’t put right

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

  • Water coming in from the roof or rainwater goods
  • Leaks through the frame itself rather than the perimeter
  • Materials that need asbestos testing before work

Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly.

Joints and surfaces we work on

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

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

What the job involves on each surface

Planned maintenance

Planned resealing replaces emergency callouts and keeps budgets predictable.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Questions we are asked in Newstead

Is Newstead too small for you to travel to?

No. Small places get the same service as large ones. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Tweed Horizons Business Centre, by Newstead?

Yes. Our area takes in Newstead and its surroundings, with estates and business parks such as Tweed Horizons Business Centre included. A few photographs and the unit address let us price the work.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building near Newstead, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Point out any areas we must not close
  • Make sure the joints can be reached
  • Send any specification or drawings in advance

Request a quote

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email us.

Advice

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Track which buildings were done and when
  • Check the asbestos register before any old mastic is disturbed
  • Check sealant joints during planned building inspections
  • List the paperwork your organisation requires when you send details

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
