Questions about Tottenham
Can you work on a hospital site such as North Middlesex University Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Tottenham, such as Rosebery Industrial Park?
Yes, sites like Rosebery Industrial Park are within our area, along with the rest of Tottenham. A few photographs and the unit address let us price the work.
Do you work in Tottenham?
Yes. We cover Tottenham and the rest of Greater London. To discuss a job, call the office on 01277 525 020 or send details through our quote form.
Do you take on mastic snagging only?
Yes. Snag-only work is something we take on and damaged joints are redone properly.
What does a mastic package normally include?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How much does the work cost?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
How we handle construction mastic in Tottenham
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, brick and block movement joints and internal decorators’ caulk, and the usual reasons a site gets in touch are a long mastic snag list close to completion and failed sealant in an existing building being refurbished. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Tottenham, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Tottenham must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in Tottenham starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Agree which areas must stay open
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.
Related advice
Maintenance after handover
To get the most from the new sealant:
- Check frame gaps are within the sealant’s range before sealing
- Keep scrapers and abrasive pads off new beads
- Get the mastic subcontractor involved early in the programme
- Record the products used in the O&M file
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. We can advise if a joint needs a different product.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We flag them as soon as we see them.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Signs you need construction mastic in Tottenham
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Most enquiries start with something like this:
- Frame perimeters left unsealed or poorly sealed
- Failed sealant in an existing building being refurbished
- Internal caulk splitting as the building dries out
- Different trades sealing to different standards
Projects at schools like The Mulberry Primary School work to term dates, so mastic is programmed tightly.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
- How joint depth will be controlled
Contractors’ notes for Tottenham
The ULEZ covers the whole of Greater London, Tottenham included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed. Tottenham has several hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
For contractors on a campus like University of Portsmouth Walthamstow Campus, 2.4 miles to the south-east of Tottenham, facade and perimeter sealing has to fit around students and term dates. New units and refits on sites such as Rosebery Industrial Park, 0.5 miles to the east of Tottenham, need their panel and perimeter joints sealed to the specification.
Tottenham is about 6 miles north-east of Marylebone, in Greater London. Anywhere in N17, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Greater London, 764 places are covered, Tottenham among them. Sites around London have their own page, roughly 7 miles from Tottenham.
Work on mastic packages is covered throughout N17, N15 and N18, whatever the building. We cover commercial and managed buildings on New Road, High Road and Reed Road and the roads nearby.

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Cost factors for mastic packages
Before we quote, we look at:
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
- The size and state of each joint
- Travel to remote or island sites
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Your programme or deadline
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email drawings and photos to discuss it first.
