Your questions answered

Is St John's Town of Dalry too small for you to travel to?

Not at all. St John's Town of Dalry is within our area. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What paperwork can you provide for a job in St John's Town of Dalry?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Can you clear a mastic snag list before handover?

Yes. We can work through a mastic snag list area by area before handover, cutting out damaged or poor joints and resealing them.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you fit around our programme?

We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start.

Do you use the sealant named in the specification?

The specification decides the product. Specifications often reference BS EN 15651 or BS 6213.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Why it’s worth doing now in St John's Town of Dalry

A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What you get with us

  • RAL and finish matching where the product range allows
  • Fixed quotes based on photographs, drawings or a visit
  • A range of standard colours, depending on the product
  • Sealing commercial buildings since 2005

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Damage to finishes by other trades after we’ve sealed
  • Glazing units that are cracked or misted
  • Frames fitted out of tolerance

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.

Surface by surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
