Mastic sealing across Tottenham
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Mastic sealing in Tottenham
Across Tottenham and the rest of Greater London, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. We work on balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks, and what we are called in for most is complaints coming in block by block and window mastic that has split and shrunk. Whoever orders the work in Tottenham, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a London area such as Tottenham, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Tottenham: questions and answers
Can you work at a site such as Rosebery Industrial Park, by Tottenham?
Yes. Our area takes in Tottenham and its surroundings, with estates and business parks such as Rosebery Industrial Park included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you send RAMS and CSCS details before starting?
We’re 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.
Block-wide mastic in Tottenham
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods. The 2 miles around Tottenham include three care or nursing homes. 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 The Mulberry Primary School need frame and external mastic kept sound like any building. Landlords with units on estates such as Rosebery Industrial Park, 0.5 miles east of Tottenham, can bring frame, door and external mastic across several units into one programme. Owners of student blocks near University of Portsmouth Walthamstow Campus, 2.4 miles south-east of Tottenham, can schedule frame and external mastic for the summer vacation.
Tottenham is about 6 miles north-east of Marylebone, in Greater London. If you are looking for mastic sealing in Tottenham, we can help. Tottenham is one of 764 places in Greater London on our list for mastic joints. For work in that direction, see our London page (7 miles or so).
Anyone looking for mastic sealing in N17, N15 and N18 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on New Road, High Road and Reed Road are within our area. With the A10 nearby, Tottenham is straightforward for us to reach. Just outside Tottenham, we also work in Broadwater Farm (1 mile west), Tottenham Hale (1 mile south-east), Tottenham Green (1 mile south), South Tottenham (1 mile south) and Seven Sisters (1 mile south). A short drive away, we cover London (7 miles south), City of Westminster (7 miles south-west), Marylebone (6 miles south-west), Kensington (9 miles south-west), St Pancras (5 miles south-west) and Shoreditch (5 miles south).
Local landmarks in Tottenham
We work on buildings around Bruce Castle Park, The John Loughborough School and Northumberland Park Community School, among other places. There’s a railway station in Tottenham itself: Bruce Grove station. Well-known places in the area include North Middlesex University Hospital (1.1 miles north) and Markfield Beam Engine and Museum (1.1 miles south). For a walk, there’s Highgate Hill and Railway Fields.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in Tottenham, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- 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.
- 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.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Flag any permit to work we will need
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work

Advice
Leave it or put it right?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Read our cost guide and our accreditations.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Removal of failed or old sealant
- Whether the work must be split into stages
- The site’s rules and procedures
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- The postcode of the building
- Approximate linear metres or a joint schedule
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email us if you’d rather talk the job through.
When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Broken glass or failed sealed units
- Asbestos-containing sealant, which we don’t remove
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Keep a record of when each building was resealed
- Reduce knocks to communal area joints
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.

Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
