How we handle construction mastic in Bankside
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in Bankside, following the trades through the building as rooms and elevations become ready. The enquiries we see most involve missed perimeter joints on a new elevation and new external sealant already peeling away, across brick and block movement joints, internal decorators’ caulk and window and door perimeters. One point of contact handles commercial sealant work in Bankside from the first photos to the final walk-round, whether it’s one building or several.
Construction in a London area such as Bankside means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
After the work
For the best life from the joints:
- Flag uneven or tapered frame gaps early
- Keep scrapers and abrasive pads off new beads
- Bring the mastic contractor in after the last trades are through
- Protect sealed areas from following trades
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.
Your questions answered
Do you take on jobs in Bankside 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. The ULEZ covers the whole of Greater London, which we allow for
Can you work on a hospital site such as London Bridge Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Bankside in your area?
Yes. We cover Bankside and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or send details through our quote form.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Construction mastic in Bankside: the local picture
The area within 2 miles of Bankside holds a good number of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Bankside 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.
Units on estates such as Grand Vitesse Industrial Estate, less than half a mile south of Bankside, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as London Bridge Hospital, which lies east of Bankside, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Bankside is about 1 mile north of London, in Greater London. Commercial clients in Bankside can call on us for mastic packages, as part of our coverage of Greater London. Bankside is one of 764 places we cover in Greater London for mastic packages.
If you need construction mastic in SE1, EC4Y and EC4V, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Bear Lane, Bush Lane and Swan Lane. Bankside sits on or close to the A201 and A300, which helps when planning parking and deliveries for the job. If your building is just outside Bankside, we cover Blackfriars (1 mile north-west), Temple (1 mile north-west), Temple Bar (1 mile north-west), Waterloo (1 mile south-west) and Smithfield (1 mile north). Bigger towns within reach include Kensington (4 miles west), Walthamstow (6 miles north-east), Hampstead (5 miles north-west), Ruislip (14 miles west), Brompton (3 miles west) and Stockwell (3 miles south).

Open spaces near Bankside include Ludgate Hill and Barnsbury Wood.
What we are called out for in Bankside
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Any of the following is a good reason to get the joints checked over:
- Sanitary sealant damaged by following trades
- Perimeter gaps outside the sealant’s range
- Existing joints on a refurb that need cutting out and resealing
- A long mastic snag list close to completion
Projects at colleges like Morley College London (to the south-west of Bankside) tend to run to term dates, so the mastic is planned tightly.

What else we do in Bankside
Why it’s worth doing now in Bankside
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Getting scaffold, permits or access booked in Bankside takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Why appoint us
- One phone line for London, the South East and Scotland
- Fixed quotes based on photos, drawings or a visit

From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. 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.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- 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.
Before we start on site
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000

Advice
Surface by surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent following the programme.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
