When to call us in Sutton
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back.
If one of these sounds familiar, it’s time for a closer look:
- Sealant pulling away from frames or panels
- Gaps between rainscreen or cladding panels
- Staining on stone next to old sealant
- Hard, chalky sealant that no longer flexes
On a campus such as University for the Creative Arts - Epsom, 3.9 miles to the south-west of Sutton, new teaching buildings and residences are typically built and refurbished around the academic year.

About our facade sealing in Sutton
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. Site teams most often ask us about perimeter joints where frames meet the structure and unsightly perimeter sealant on a visible elevation, on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Sutton is the same: the right product in a properly prepared joint.
Every London site, Sutton included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
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 are upfront about that.

What else we do in Sutton
Surface by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.
Why it’s worth doing now in Sutton
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Your questions answered
Can work at a site such as University for the Creative Arts - Epsom fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
When can the area be used after sealing?
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.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Facades, frames and programmes in Sutton
The area within 2 miles of Sutton holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in Sutton falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For contractors at a college like Sutton College of Learning for Adults, less than half a mile south of Sutton, perimeters and internal sealant are timed for the holidays. New wings at hospitals like Queen Mary's Childrens' Hospital (1.1 miles north of Sutton) bring long runs of window and panel joints to seal.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Ask about asbestos in pre-2000 mastic
- Don’t wait for a second leak before calling
- Keep pressure washers away from fresh sealant
- Share access with other external trades
Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. 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.
- 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.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
- Agree which areas must stay open
