Construction mastic in Hoxton
Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on window and door perimeters, cladding and panel joints and sanitary and kitchen joints, and the failures we are asked to look at most are missed perimeter joints on a new elevation and external joints sealed in damp or cold conditions that are now failing. For commercial sealant work in Hoxton, you deal with one contact from quote to sign-off, whether it’s one building or several.
Every London site, Hoxton included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- How accessible the joints are
- Distance, for remote addresses
- The size and state of each joint
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- What the building is and how it’s used
- Any dates the work must fit around
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Common problems we fix in Hoxton
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding, so preparation matters as much here as on a reseal.
Things that normally lead to an enquiry:
- Oversized or tapered gaps around new frames
- Window and door perimeters that won’t pass inspection
- Different trades sealing to different standards
- Sanitary sealant damaged by following trades
Further education sites such as New City College, under half a mile to the south-east of Hoxton, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Questions to ask before you book
- How they handle RAMS and site documents
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
- How the existing material will be dealt with
Building and refurbishing in Hoxton
There are a good number of hotels within about 2 miles of Hoxton. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, Hoxton is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Units on estates such as Bayford Street Industrial Centre (to the east of Hoxton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. University estates such as University of Wales Trinity Saint David London (to the west of Hoxton) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Hoxton is about 2 miles north of London, in Greater London. Across the N1 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Hoxton is one of 764 places we cover in Greater London for mastic packages.
Commercial sites across N1, N1P and EC1V are covered. We cover commercial and managed buildings on City Road, Noel Road and East Road and the roads nearby. With the A1200 and A1208 nearby, Hoxton is easy to get to with materials and equipment. If your building is just outside Hoxton, we cover Haggerston (1 mile east), Shoreditch (1 mile south-east), Canonbury (1 mile north), De Beauvoir Town (1 mile north) and St Luke's (1 mile south-west). Further afield, our area takes in City of Westminster (3 miles south-west), Marylebone (3 miles south-west), Kensington (6 miles south-west), Walthamstow (4 miles north-east), Hampstead (4 miles west) and Ruislip (14 miles west). Among the larger centres in Greater London is Hoxton, and its commercial and public buildings are all within our area.

Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot

Advice
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Common questions from Hoxton clients
Will you take on work at estates like Bayford Street Industrial Centre, close to Hoxton?
Yes. We cover Hoxton and the area around it, including industrial estates, business parks and retail parks such as Bayford Street Industrial Centre. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Would you work within a site like Moorfields Eye Hospital (City Road campus)?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does a mastic package usually include?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.
What happens if the weather stops external sealing?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Building owners, agents and FMs in Hoxton
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Also in Hoxton
Why deal with it now?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area usually clears more for less disruption and saves applicators coming back again and again. Snagging can be priced as a separate stage. 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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
