How we handle mastic sealing in Shawhead

Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on shopfronts below residential blocks, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is movement joints with sealant missing and worn sealant at communal door frames. Looking for mastic applicators who cover Shawhead? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

For buildings around Shawhead, we group the work to keep travel and visits down. A list of addresses and photos lets us quote for them together.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Planned mastic for Shawhead portfolios

Being in the east of Scotland, Shawhead gets less rain than the west coast. Cold mornings still limit when outside mastic can go on. We plan block programmes with some give for it

Owners near Shawhead can renew frame and external mastic block by block on one programme.

Why it’s worth doing now in Shawhead

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Renewing every failing joint on one visit is the sensible approach for a place like Shawhead. Photos of each area help us quote the whole job.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

What you get with us

  • Work carried out by CSCS-carded applicators
  • CHAS accredited
  • A range of standard colours, depending on the product
  • RAL and finish matching where the product range allows

Read what affects the cost and our accreditations and insurance.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Log resealing dates block by block
  • List the paperwork your organisation requires when you send details
  • Reduce knocks to communal area joints
  • Prioritise elevations facing the weather

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

Common problems we fix in Shawhead

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

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

  • Communal area joints that look neglected
  • Leaks at window and door perimeters
  • Failed external movement joints
  • Draughts at frames across a block

Near Shawhead, we review each elevation first so the quote covers what actually needs doing.

What your quote should include

  • How they handle RAMS and site documents
  • Whether primer will be used where the manufacturer specifies it
  • Will CSCS-carded applicators be on site?
  • How the existing material will be dealt with

How to choose a sealant contractor

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Shawhead is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Agree which areas must stay open

Ask for a quote

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email us if you’d rather talk the job through.

Your questions answered

Will you price a mastic programme across our Shawhead portfolio?

Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.

Is Shawhead too small for you to travel to?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.

Is asbestos a concern with old mastic?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

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, and we confirm it before leaving site.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
