Facade sealing in Stoke Newington
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you are dealing with gaps between rainscreen or cladding panels and cold air coming in at window perimeters, we can put it right, whatever the surface. Whoever orders the work in Stoke Newington, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Every London site, Stoke Newington included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Stoke Newington can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we will be in

Keeping the joints sound
A few simple habits keep the new joints working:
- Don’t wait for a second leak before calling
- Avoid patch repairs on failed facade joints
- Avoid harsh cleaners on facade sealant
- Ask about asbestos in pre-2000 mastic
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.
Questions about Stoke Newington
Can you work on a hospital site such as St Ann's Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Frogmore Industrial Estate, close to Stoke Newington?
Yes, sites like Frogmore Industrial Estate are within our area, along with the rest of Stoke Newington. Photos and a short description are enough for a first look.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How is access to upper-level joints handled?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. Removal of asbestos isn’t something we do.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Facades, frames and programmes in Stoke Newington
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Stoke Newington. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A good number of hotels sit less than 2 miles from Stoke Newington. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Hotels like The Rose Hotel, 0.7 miles to the south-east of Stoke Newington, rarely close for long, so refurbishment mastic is phased floor by floor. On a healthcare site such as St Ann's Hospital (1.2 miles north of Stoke Newington), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Further education sites such as City & Islington College (to the west of Stoke Newington) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Quoting for work in Stoke Newington
To price the job, we consider:
- Distance, for remote addresses
- Phasing around occupants
- How much there is to seal
- Backing rod, priming and other preparation
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Any dates the work must fit around
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Joints too narrow for the movement they take, which need redesign
- Cracked or spalling substrates that need repair before sealing
- Damp caused by condensation inside the building
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
What we seal
- Cladding panel joints
- Shopfront frames
- Coping and flashing joints
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Window and door perimeters
How the job changes by surface
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch as the frame moves.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.
Building owners, agents and FMs in Stoke Newington
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
