Different surfaces, different methods
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.
How we handle facade sealing in Upper Edmonton
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with damp patches beside frames after rain and draughts around frames and panels, we can put it right. For commercial sealant work in Upper Edmonton, you deal with one contact from quote to sign-off, whether it’s one building or several.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Upper Edmonton must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What sets the cost
To price the job, we consider:
- The product specified
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- Joint width, depth and condition
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Any dates the work must fit around
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or send details through our quote form.
Questions we are asked in Upper Edmonton
Do you work in London buildings with loading restrictions?
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’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Can work at a site such as University of Portsmouth Walthamstow Campus fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Share access with other external trades
- Insist on a full cut-out when joints are renewed
- Keep the sealant details on the building file
- Inspect facade joints on a regular cycle
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Facade sealing around Upper Edmonton: what changes locally
As part of Greater London, Upper Edmonton 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. There are several hotels within about 2 miles of Upper Edmonton. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
New wings at hospitals like North Middlesex University Hospital (under half a mile west of Upper Edmonton) bring long runs of window and panel joints to seal. When a school such as St John and St James CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Projects at colleges like Haringey Sixth Form College, 0.6 miles to the south-west of Upper Edmonton, tend to run to term dates, so the mastic is planned tightly.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Upper Edmonton can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.

What else we do in Upper Edmonton
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Leave it or put it right?
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What you get with us
- Old sealant cut out, never sealed over
- Standard and matched colours in many product ranges
