Mastic sealing in Hoxton
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with mastic failing across several blocks on an estate and repeated reactive repairs to the same buildings, we can put it right. A single leaking joint is often how a building in Hoxton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Every job we finish is backed by a 12-month workmanship guarantee, in Hoxton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. 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.

- The quote is fixed and split as suits you.

Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
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.
What happens if it’s left?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Signs you need mastic sealing in Hoxton
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
It’s worth sending us details if you spot any of the following:
- Occupiers reporting cold air round windows
- Leaks at window and door perimeters
- Repeated reactive repairs to the same buildings
- A mix of products and colours from past repairs
If you own or manage units on a site such as Bayford Street Industrial Centre, 1.3 miles east of Hoxton, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Before you book anyone
- How the joint faces will be prepared and primed
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
What the job involves on each surface
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.
Planned mastic for Hoxton portfolios
The 2 miles around Hoxton include 10 care or nursing homes. Care home owners need frame and external mastic kept sound without unsettling residents. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.
For agents with blocks near Hoxton station (under half a mile east of Hoxton), a block-wide mastic programme deals with frames, balconies and entrances in one go. If you manage student housing near a university such as University of Wales Trinity Saint David London, less than half a mile west of Hoxton, the summer turnaround is the time for mastic.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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.
Questions about Hoxton
Do you take on jobs in Hoxton where loading and access are tightly controlled?
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
Can you work in a care home near Hoxton with residents in?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
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. Internal work is far less affected.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
