Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Why us?

- Over 20 years of commercial sealing
- Workmanship guaranteed for 12 months
- One phone line for London, the South East and Scotland

About our mastic sealing in Bethnal Green
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve a mix of products and colours from past repairs and no planned programme for sealant, across balcony and threshold joints, communal kitchens and washrooms and external wall and movement joints. A single leaking joint is often how a building in Bethnal Green 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.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Planning a London job such as one in Bethnal Green starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Let building users know which areas are affected
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Group repairs into a planned programme
- Prioritise elevations facing the weather
- Check the asbestos register before any old mastic is disturbed
- Reduce knocks to communal area joints
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.

Common questions from Bethnal Green clients
Can you work at a site such as Anchor Retail Park, by Bethnal Green?
Yes, sites like Anchor Retail Park are within our area, along with the rest of Bethnal Green. Photos and a short description are enough for a first look.
We manage a building near Cambridge Heath station. Can you help?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work in Bethnal Green?
Yes. We cover Bethnal Green, and you can ring 01277 525 020 or send photos by email to get started.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- Working within restricted access windows
- The site’s rules and procedures
- Access and working height
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Asbestos survey details if the building is older
- Any dates the work must fit around
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or send details through our quote form to discuss it first.
When to call us in Bethnal Green
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
Common reasons buildings call us in:
- No planned programme for sealant
- Occupiers reporting cold air round windows
- Water getting in round frames after rain
- Cracked, hardened mastic round windows on a block
For agents with blocks near Cambridge Heath station (under half a mile north-east of Bethnal Green), a block-wide mastic programme deals with frames, balconies and entrances in one go.
