Construction mastic in Dormansland
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you have frame perimeters left unsealed or poorly sealed and failed sealant in an existing building being refurbished, we can put it right. Whoever orders the work in Dormansland, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Dormansland, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

FAQs: Dormansland
Is a hospital such as Queen Victoria Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Scanda-Hus Business Park, near Dormansland?
Yes. We cover Dormansland and the area around it, including industrial estates, business parks and retail parks such as Scanda-Hus Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we’ll confirm with the quote.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Which sealant will you use?
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.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
Building owners, agents and FMs in Dormansland
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When to call us in Dormansland
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
What tends to prompt an enquiry:
- Perimeter gaps outside the sealant’s range
- External joints sealed in damp or cold conditions that are now failing
- Snag items on joints that need redoing before handover
- Cracks opening in caulked internal joints
When a school such as Dormansland Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Before you book anyone
- What level of public liability insurance do they hold?

Different surfaces, different methods
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and reduces snags.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
Keeping the joints sound
For the best life from the joints:
- Don’t schedule sealing before decorators and flooring are done
- Check frame gaps are within the sealant’s range before sealing
- Protect sealed areas from following trades
- Keep product details for future maintenance
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Mastic packages on Dormansland sites
