Sullom: questions and answers
Does the sea air around Sullom change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can the mastic package for our job in Sullom follow the site programme?
Yes. The mastic is planned around your key stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.
How do you work with the site programme?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it.
How much does the work cost?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email a schedule or drawings with a description of the work.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use.
Does weather affect external mastic work?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.
Construction mastic in Sullom, 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. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions, and the failures we’re asked to look at most are bath and shower joints scraped during the final clean and frame gaps too wide for sealant alone. One point of contact handles commercial sealant work in Sullom from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In smaller places such as Sullom, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What else we do in Sullom
Why deal with it now?
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. For buildings near Sullom, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Glazing units that are cracked or misted
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Where we work in Sullom
- Internal decorators’ caulk
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
Keeping the joints sound
After handover, a little attention goes a long way:
- Flag uneven or tapered frame gaps early
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Allow flexibility for external sealing in damp or cold weather
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Sullom, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Flag any permit to work we’ll need
- Point out any areas we must not close
- Point out parking and an unloading spot

New build and refits around Sullom
Sullom sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Sullom is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. External dates keep a little give.
Sites around Sullom get mastic sealed to the drawings and the programme, nothing improvised. A facade joint near Sullom lasts when width, depth and backing are right, not just the finish.
