Facade sealing in Tottenham Green
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. Most enquiries involve facade joints cracked through the middle and air leaks through failed facade joints, across coping and flashing joints, cladding panel joints and shopfront frames. Most enquiries from Tottenham Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Tottenham Green must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Leave it or put it right?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Getting scaffold, permits or access booked in Tottenham Green takes effort, so it makes sense to deal with every failing joint while access is in place.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Check that rainwater leaves the facade the way it was designed to
- Plan facade sealing alongside redecoration
- Insist on a full cut-out when joints are renewed
- Confirm the survey covers external sealants in older buildings
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Signs you need facade sealing in Tottenham Green
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.
It’s worth sending us details if you spot any of the following:
- New sealant peeling off old mastic
- Perimeter joints where frames meet the structure
- Cladding panel joints that have opened up
- Air leaks through failed facade joints
Extensions at sites like St Ann's Hospital (to the south-west of Tottenham Green) normally sit beside working departments, and the mastic follows strict access rules.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Their public liability cover
- Who will actually carry out the work
- Can the work be phased to keep areas open?
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Water getting in through cracked render or porous masonry
- Arranging specialist high-level access, which is planned with the client
- Joints too narrow for the movement they take, which need redesign
If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What else we do in Tottenham Green
Mastic packages on Tottenham Green sites
There are plenty of hotels within about 2 miles of Tottenham Green. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Tottenham Green is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Building work at universities like University of Portsmouth Walthamstow Campus (to the east of Tottenham Green) is often timed for the summer, mastic included. Units on estates such as Tottenham Hale Retail Park, 0.5 miles to the east of Tottenham Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Tottenham Green is about 2 miles west of Walthamstow, in Greater London. Businesses, contractors and managing agents in Tottenham Green use us for work on facade joints, as part of our coverage of Greater London. Across Greater London, 764 places are covered, Tottenham Green among them. For work in that direction, see our London page.

On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Confirm the product named in the specification
- Let building users know which areas are affected
- Share your working hours and any access restrictions

Advice
FAQs: Tottenham Green
Does your area include sites such as Tottenham Hale Retail Park, near Tottenham Green?
Yes, sites like Tottenham Hale Retail Park are within our area, along with the rest of Tottenham Green. A few photos and the unit address let us price the work.
Would you work within a site like St Ann's Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Site staff or a sealant specialist?
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
