Questions about Isle of Dogs
Do you take on jobs in Isle of Dogs where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Will you work in a care home in Isle of Dogs without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Leaks from above rather than through a joint
- Masonry that has broken away beside the joint
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.
What we seal
- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. We plan around the site hours and access windows you give us.
What happens if it’s left?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What you get with us
- Standard and matched colours in many product ranges
- Public liability insurance in place
- CHAS accredited contractor
- 12 months’ guarantee on every job

Aftercare for building managers
For the best life from the joints:
- Plan resealing building by building rather than complaint by complaint
- Ask residents or tenants to report leaks and draughts early
- Keep a record of when each building was resealed
- Reduce knocks to communal area joints
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Our process
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
