Construction mastic for commercial buildings in Chartway Street
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. If you have perimeter gaps outside the sealant’s range and sealant knocked or painted over by other trades, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chartway Street is the same: the right product in a properly prepared joint.
Construction in and around smaller places such as Chartway Street is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Why act early in Chartway Street
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. If the frame is life-expired, we will tell you. For buildings around smaller places like Chartway Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Aftercare for building managers
A few simple habits keep the new joints working:
- Get the mastic subcontractor involved early in the programme
- Note which sealant went where at handover
- Release areas for mastic once other trades have finished in them
- Brief following trades on areas that have been sealed
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Mastic packages on Chartway Street sites
Rainfall across the South East, Chartway Street included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Chartway Street lies roughly 36 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
For contractors on a campus like Canterbury Christ Church University (4.2 miles north-east of Chartway Street), facade and perimeter sealing has to fit around students and term dates. With historic properties like Leeds Castle (2 miles north of Chartway Street) in the area, refurbishment work often meets old masonry that needs compatible sealants. When units on a site such as Park Wood Trading Estate, 2.5 miles north-west of Chartway Street, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
