From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Where we can, we combine work around Keyhead with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site
- Explain the parking and delivery arrangements
- Send your site hours and access windows
- Confirm the product named in the specification

Advice
Construction mastic in Keyhead, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. If you have perimeter gaps outside the sealant’s range and frame perimeters left unsealed or poorly sealed, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Keyhead, preparation and product choice get the time they need.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Keyhead that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
A 12-month guarantee applies to all our work in Aberdeenshire. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Contractors’ notes for Keyhead
With the shore within about 3 miles, Keyhead counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Being in the east of Scotland, Keyhead gets less rain than the west coast. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We agree external dates with the site team and keep internal work ready.
A facade joint near Keyhead lasts when width, depth and backing are right, not just the finish.

After the work
For the best life from the joints:
- Use the product the specification names
- Note which sealant went where at handover
- Share drawings and the specification as soon as possible
- Brief following trades on areas that have been sealed
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
What affects the price in Keyhead
Each job is priced on its own details. The main factors are:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The product specified
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Whether the building will be occupied during the work
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Keyhead: questions and answers
Does the sea air around Keyhead change the choice of sealant?
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.
Can the mastic package for our job in Keyhead follow the site programme?
Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
What the job involves on each surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services. Tell us what records you need and we will confirm with the quote.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Common problems we fix in Keyhead
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
If one of these sounds familiar, it’s time for a closer look:
- Inconsistent sealant finishes from plot to plot
- Old sealant on a refurbishment that needs stripping before new work
- Missed perimeter joints on a new elevation
- Bath and shower joints scraped during the final clean
For contractors building in or near Keyhead, we seal to the drawings, the specification and the programme.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Will failed sealant be removed rather than covered?
- Whether their applicators hold CSCS cards
- Can the work be phased to keep areas open?
