How we handle mastic sealing in Homerton
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and what we’re called in for most is draughts at frames across a block and repeated reactive repairs to the same buildings. A single leaking joint is often how a building in Homerton first comes to us: we look at the rest while we are there and tell you what we find.
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.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What happens if it’s left?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Getting scaffold, permits or access booked in Homerton takes effort, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What you get with us
- One number for every site we cover
- Colours confirmed for the specified product

FAQs: Homerton
Will you work in a care home in Homerton without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
What sets the cost
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- How much there is to seal
- How accessible the joints are
- Phasing around occupants
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- Whether an asbestos survey exists
- The postcode of the building
- Any specification or named product
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Common problems we fix in Homerton
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Typical triggers for a call:
- Occupiers reporting cold air round windows
- Complaints coming in block by block
- Estate-wide sealant that is simply worn out
- Cracked, hardened mastic round windows on a block
Owners of student blocks near Loughborough University London, 1.1 miles east of Homerton, can schedule frame and external mastic for the summer vacation.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Can the work be phased to keep areas open?
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. In Homerton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
