How we handle construction mastic in West Ham
Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in West Ham, send drawings through our quote form, or phone or email us to talk it through. We work on cladding and panel joints, brick and block movement joints and floor and skirting junctions, and what we’re called in for most is oversized or tapered gaps around new frames and a mastic package split between trades with no clear owner. Most enquiries from West Ham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as West Ham means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
Our workmanship is guaranteed for 12 months, in West Ham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Questions we are asked in West Ham
Would you work within a site like Newham University Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we have finished isn’t covered.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
Different surfaces, different methods
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Record requirements are agreed with the quote.
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. In West Ham, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Explain the parking and delivery arrangements
- Share your working hours and any access restrictions

Sites and facades in and around West Ham
The ULEZ covers the whole of Greater London, West Ham included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in. A good number of hotels sit less than 2 miles from West Ham. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Work at a hotel such as City View Hotel, under half a mile north-west of West Ham, tends to be programmed around bookings, mastic included. Hospital estates such as Newham University Hospital, 1.4 miles to the south-east of West Ham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief following trades on areas that have been sealed
- Ask cleaners to use soft cloths around fresh sealant
- Ask installers to correct oversized gaps first
- Share drawings and the specification as soon as possible
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Building owners, agents and FMs in West Ham
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

When to call us in West Ham
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Typical triggers for a call:
- Old sealant on a refurbishment that needs stripping before new work
- Missed perimeter joints on a new elevation
- Internal caulk splitting as the building dries out
- Sealant knocked or painted over by other trades
University estates such as University of East London (0.8 miles north-west of West Ham) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- Their plan for phasing and protecting the area
- How joint depth will be controlled
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Some joints are best left to specialists: 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.
