Common problems we fix in Sutton Common
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Typical triggers for a call:
- Gaps between rainscreen or cladding panels
- Draughts around frames and panels
- Patch repairs that keep failing
- Discoloured or dirty facade joints
For a contractor at a hotel such as Ashling Tara Hotel, which lies south-east of Sutton Common, the mastic often has to be finished before a reopening date.

Facade sealing in Sutton Common, done properly
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on coping and flashing joints, cladding panel joints and shopfront frames, and the failures we’re asked to look at most are weathered facade joints that have lost their grip and weathered joints at frame-to-structure perimeters. Looking for mastic applicators who cover Sutton Common? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a job in Sutton Common, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Share your working hours and any access restrictions
- Arrange parking or a loading space
- Tell us what induction or permit system the site runs

Contractors’ notes for Sutton Common
A 2-mile radius around Sutton Common takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Sutton Common included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For contractors on a campus like Kingston University, 4.2 miles to the north-west of Sutton Common, facade and perimeter sealing has to fit around students and term dates. Projects at colleges like Merton College (0.7 miles north of Sutton Common) tend to run to term dates, so the mastic is planned tightly.

Landmarks near Sutton Common
We work on buildings around Lord Nelson pub, Merton College and Glenthorne High School. There’s a railway station in Sutton Common itself: St Helier station.

Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Your questions answered
Can work at a site such as Kingston University fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you take on a job at a hospital such as St. Helier Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, so we plan around the forecast.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Damaged frames that need replacing
- Providing access systems for the work
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.

Looking after the joints
To get the most from the new sealant:
- Add perimeter sealant to planned maintenance checks
- Insist on a full cut-out when joints are renewed
- Keep pressure washers away from fresh sealant
- Don’t wait for a second leak before calling
Record the sealant type and date on the building file. Future work can then match the product and colour.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
