Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
About our mastic sealing in Yiewsley
Owners and agents typically inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the usual reasons a site gets in touch are draughts at frames across a block and estate-wide sealant that is simply worn out. One point of contact handles commercial sealant work in Yiewsley from the first photos to the final walk-round, whether it’s one building or several.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Looking after buildings in and around Yiewsley
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Leaks through the frame itself rather than the perimeter
- Broken glass or failed sealed units
- Roof leaks, gutters or failed flashings that aren’t sealant joints

Why it’s worth doing now in Yiewsley
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. 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.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

FAQs: Yiewsley
Do you work for managing agents with blocks near Southall station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Do you cover business parks and estates near Yiewsley, such as Adrienne Business Centre?
Yes, sites like Adrienne Business Centre are within our area, along with the rest of Yiewsley. A few photos and the unit address let us price the work.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
When to bring in a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
- Keep a record of when each building was resealed
- Plan resealing building by building rather than complaint by complaint
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- 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.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Let us know about inductions and permits
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000
