Construction mastic for commercial buildings in Highsted
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you are dealing with external joints sealed in damp or cold conditions that are now failing and sealant knocked or painted over by other trades, we can help, on sanitary and kitchen joints, window and door perimeters and cladding and panel joints alike. One point of contact handles commercial sealant work in Highsted from the first photos to the final walk-round, for single jobs and planned programmes alike.
In the countryside around places like Highsted, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How the job changes by 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.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
New build and refits around Highsted
Several hotels sit less than 2 miles from Highsted. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. At about 38 miles from central London, Highsted is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
New units and refits on sites such as Kent Science Park (0.8 miles south-west of Highsted) need their panel and perimeter joints sealed to the specification. Hotel extensions and refits, at places such as The George Hotel, which lies north of Highsted, normally run between busy periods, so the sealing is squeezed into short windows. On a campus such as Canterbury Christ Church University, which lies south-west of Highsted, new teaching buildings and residences are usually built and refurbished around the academic year.

Questions about Highsted
Could you schedule work at a campus like Canterbury Christ Church University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you take on a job at a hospital such as Sittingbourne Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What joints do you seal on a new build?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. Public liability insurance is in place.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Looking after the joints
Once the work is signed off, these steps help:
- Flag uneven or tapered frame gaps early
- Share drawings and the specification as soon as possible
- Ask cleaners to use soft cloths around fresh sealant
- Allow flexibility for external sealing in damp or cold weather
Expect some settlement in the first months. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks.
