How we handle construction mastic in Haggerston
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. That keeps the work right first time and saves rework. We work on cladding and panel joints, window and door perimeters and sanitary and kitchen joints, and what we’re called in for most is existing joints on a refurb that need cutting out and resealing and cracks opening in caulked internal joints. Most enquiries from Haggerston start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in a London area such as Haggerston means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes whatever the programme allows, since the work follows the trades as areas are released, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Haggerston can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
Quotes
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send photos by email.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Record the products used in the O&M file
- Keep scrapers and abrasive pads off new beads
- Don’t force external sealing on a damp or frosty day
- Check frame gaps are within the sealant’s range before sealing
Any damage after we have finished should go on the snag list straight away. We can return to clear snags before handover as agreed in the quote.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We flag them as soon as we see them.
How the quote is worked out
Before we quote, we look at:
- Location, for remote and island sites
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Working within restricted access windows
A quote for mastic packages depends on how many there are, their condition and the access. Call for a quote.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- Whether an asbestos survey exists
- Clear photos of the problem areas
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Building and refurbishing in Haggerston
A 2-mile radius around Haggerston takes in a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Haggerston included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
New wings at hospitals like Mildmay Mission Hospital, 0.5 miles south of Haggerston, bring long runs of window and panel joints to seal. Building work at universities like University of Wales Trinity Saint David London (to the west of Haggerston) is often timed for the summer, mastic included.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Oversized gaps that need packing or adjustment by others
- Joints damaged after sign-off by following trades
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
What we seal
- Cladding and panel joints
- Internal decorators’ caulk
- Window and door perimeters
- Floor and skirting junctions
- Sanitary and kitchen joints
- Brick and block movement joints
When to call us in Haggerston
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Most enquiries start with one or more of the following:
- Failed sealant in an existing building being refurbished
- Frame perimeters left unsealed or poorly sealed
- Sealant knocked or painted over by other trades
- A mastic package split between trades with no clear owner
When a college such as New City College (to the south of Haggerston) builds or refurbishes, the mastic package normally has to fit around students and staff.

Haggerston: questions and answers
Is hospital work, at somewhere like Mildmay Mission Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as University of Wales Trinity Saint David London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Will you stick to the specified products?
The specification decides the product. Specifications often reference BS EN 15651 or BS 6213.
Do you take on mastic snagging only?
Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.
