Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep scrapers and abrasive pads off new beads
- Brief following trades on areas that have been sealed
- Put any product change through the designer first
- Bring the mastic contractor in after the last trades are through
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. We can advise if a joint needs a different product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We flag them as soon as we see them.
Construction mastic in Aldgate
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. If you’re dealing with frame perimeters left unsealed or poorly sealed and external joints sealed in damp or cold conditions that are now failing, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Aldgate it comes down to the same thing: the right product in a properly prepared joint.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we are asked in Aldgate
Could you schedule work at a campus like London Metroplitan University: Aldgate Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
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. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
Does the weather affect the work?
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. Indoors, the weather is rarely a problem.
Can the building stay open while you work?
Normally, yes. Phased work can be planned so areas stay in use.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Facades, frames and programmes in Aldgate
The ULEZ covers the whole of Greater London, Aldgate included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Aldgate takes in plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors on a campus like London Metroplitan University: Aldgate Campus, less than half a mile to the north-east of Aldgate, facade and perimeter sealing has to fit around students and term dates. Units on estates such as Princes Court Business Centre (0.9 miles east of Aldgate) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Work at a hotel such as Hotel Indigo London - Tower Hill (under half a mile east of Aldgate) tends to be programmed around bookings, mastic included.

What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
What sets the cost
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- How much there is to seal
- Access and working height
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
However big the job, these details speed things up:
- Your programme or deadline

Why it’s worth doing now in Aldgate
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. In Aldgate, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.
