About our mastic sealing in Rochester Riverside
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and estate-wide sealant that is simply worn out.

FAQs: Rochester Riverside
Is Rochester Riverside too small for you to travel to?
Not at all. Rochester Riverside is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Rochester station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How many days will you need on site?
It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Why it’s worth doing now in Rochester Riverside
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. In a smaller place such as Rochester Riverside, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What you get with us

How the job changes by surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Should maintenance staff do it?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
