Signs you need construction mastic in Shawfair
On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
If one of these sounds familiar, it’s time for a closer look:
- Missed perimeter joints on a new elevation
- Oversized or tapered gaps around new frames
- Snag items on joints that need redoing before handover
- New external sealant already peeling away
Further education sites such as Edinburgh College - Milton Road Campus (1.4 miles north of Shawfair) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Questions to ask before you book
- The named product and why it was chosen

- How the existing material will be dealt with

For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
What affects the price in Shawfair
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Which sealant the job calls for
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- Any specification or named product
- What the building is and how it’s used
- Photos of the joints, close up and from further back
- Drawings or a marked-up plan, if available
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Glazing units that are cracked or misted
- Oversized gaps that need packing or adjustment by others
- Approving fire stopping as compliant
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
What we seal
- Internal decorators’ caulk
- Sanitary and kitchen joints

How the job changes by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
Common questions from Shawfair clients
Can you take on a job at a hospital such as Shawfair Park Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does a coastal location like Shawfair affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product. We will flag if the detail needs a different product.
How many days will you need on site?
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 do you work with the site 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 and adjusted as things change.
