Mastic sealing for Tottenham Green sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Should maintenance staff do it?
Certain joints really need a specialist: for instance 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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
About our mastic sealing in Tottenham Green
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you have water getting in round frames after rain and old repairs sealed over failed mastic, we can put it right, on communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints alike. One point of contact handles commercial sealant work in Tottenham Green from the first photos to the final walk-round, whether it’s one building or several.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
Our workmanship is guaranteed for 12 months, in Tottenham Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we’re called out for in Tottenham Green
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Things that typically lead to an enquiry:
- Water getting in round frames after rain
- Movement joints with sealant missing
- Communal area joints that look neglected
- Mastic failing across several blocks on an estate
For agents with blocks near Seven Sisters station, less than half a mile to the south of Tottenham Green, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Before you book anyone
- What site paperwork they can supply
- Whether old or failed sealant will be cut out, not overlaid
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
Mastic sealing around Tottenham Green: points for this area
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We work to your notice and access plan. Tottenham Green has three care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
Schools and community buildings such as Earlsmead Primary School need frame and external mastic kept sound like any building. Student accommodation around universities such as University of Portsmouth Walthamstow Campus (2.4 miles east of Tottenham Green) is usually managed block by block, which suits a planned mastic programme.
Tottenham Green is about 2 miles west of Walthamstow, in Greater London. We send applicators to Tottenham Green for mastic joints, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places, large and small. We also cover London, some 6 miles away.

Looking after the joints
A few simple habits keep the new joints working:
- Look at the sunniest and most exposed elevations first
- Include mastic in your cyclical inspections
- Reduce knocks to communal area joints
- Check the asbestos register before any old mastic is disturbed
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
Leave it or put it right?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

Advice
Your questions answered
Can work in a care setting near Tottenham Green go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Does your area include sites such as Tottenham Hale Retail Park, near Tottenham Green?
Yes. Estates, retail parks and business parks around Tottenham Green, Tottenham Hale Retail Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- Working within restricted access windows
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- The postcode of the building
- The type of building and who uses it
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.
