Construction mastic for Deans sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Construction mastic in Deans, done properly
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can normally carry on while the outside waits. The enquiries we see most involve bath and shower joints scraped during the final clean and mastic snags holding up handover, on internal decorators’ caulk, cladding and panel joints and brick and block movement joints. Facilities teams, main contractors and managing agents in Deans tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Sites near smaller places like Deans can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask for joint and product checks before the package is urgent
- Don’t schedule sealing before decorators and flooring are done
- Keep finished joints away from paint, plaster and scrapers
- Allow flexibility for external sealing in damp or cold weather
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.

What the job involves on each surface
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team before sealing starts.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For a building near Deans, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Confirm the product named in the specification
- Arrange parking or a loading space
- Flag any permit to work we’ll need

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email the details over with what you know.
Advice
Your questions answered
Is a hospital such as Saint John's Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Deans too small for you to travel to?
No. Places such as Deans are covered as much as the big towns. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you install fire-rated sealant as part of a package?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems, so we wait rather than redo work.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you clear a mastic snag list before handover?
Yes. Send the snag list or photos and we’ll price it.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Mastic packages on Deans sites
Projects in Deans follow Scotland’s building regulations, with the local authority acting as verifier. We seal to the specification that sits behind the warrant. Deans has a number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as Deans Community High School, normally run to the summer holidays, mastic included. For contractors refurbishing units at places like Eliburn Office Park (0.9 miles south of Deans), the mastic covers cladding panels, roller-door and window perimeters. On a healthcare site such as Saint John's Hospital, 1.4 miles to the south-east of Deans, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Designing joint widths or choosing the specification (that sits with the designer)
- Damage to finishes by other trades after we have sealed
- Frames fitted out of tolerance
