When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How we handle facade sealing in Newington Green
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Most enquiries involve staining on stone next to old sealant and hard, chalky sealant that no longer flexes, across stone and brick facade joints, coping and flashing joints and cladding panel joints. One point of contact handles commercial sealant work in Newington Green from the first photographs to the final walk-round, whether it’s one building or several.
Around Newington Green, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

What else we do in Newington Green
How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In Newington Green, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Share the asbestos register for older buildings
- Confirm the product named in the specification
- Move anything stored against the joints

Sites and facades in and around Newington Green
Site traffic in Newington Green falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are plenty of hotels within about 2 miles of Newington Green. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Hotels like The Rose Hotel, 0.5 miles east of Newington Green, rarely close for long, so refurbishment mastic is phased floor by floor. Further education sites such as City & Islington College, 1.2 miles to the north-west of Newington Green, are extended and refurbished from time to time, with mastic often programmed into the summer break. University estates such as London Metropolitan University, 1.1 miles west of Newington Green, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Different surfaces, different methods
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Joints whose design needs changing by the specifier
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Replacing glass or failed glazing units
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly before you book.
Joints and surfaces we work on
- Shopfront frames
- Cladding panel joints
- Window and door perimeters
- Coping and flashing joints
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Don’t wait for a second leak before calling
- Ask about asbestos in pre-2000 mastic
- Share access with other external trades
- Insist on a full cut-out when joints are renewed
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Work for main contractors and building owners
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’ll confirm them with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Your questions answered
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Is a hospital such as Moorfields Eye Hospital (City Road campus) somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Do you seal facades in winter?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.
Do you cover Newington Green?
Yes. We take on work across Newington Green.
