How we handle facade sealing in Sunbury-on-Thames
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. Site teams most often ask us about new sealant peeling off old mastic and perimeter sealant that has split or peeled away, across window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure. For commercial sealant work in Sunbury-on-Thames, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Construction in a town such as Sunbury-on-Thames is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Town-centre premises in Sunbury-on-Thames may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- 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.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work

Common problems we fix in Sunbury-on-Thames
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Any of the following is a good reason to get the joints checked over:
- Previous reseals run over old sealant
- Perimeter sealant that has split or peeled away
- Staining on stone next to old sealant
- Leaks at window and door perimeters
Further education sites such as West Thames College - Skills Centre (to the north-east of Sunbury-on-Thames) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Why it’s worth doing now in Sunbury-on-Thames
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. In a town like Sunbury-on-Thames, a split, stained or mouldy joint is often the first thing visitors notice. Renewing it keeps the building looking cared for.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why us?
- Health and safety: CHAS accredited
- One phone line for London, the South East and Scotland
- 12-month guarantee on workmanship
- Failed material removed, not covered up

Questions we’re asked in Sunbury-on-Thames
Can you work at a site such as Sunbury International Business Centre, by Sunbury-on-Thames?
Yes. Our area takes in Sunbury-on-Thames and its surroundings, with estates and business parks such as Sunbury International Business Centre included. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Could you schedule work at a campus like St Mary's University for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Report water ingress at frames as soon as it shows
- Combine resealing with other works that need access
- Brief window cleaners about newly sealed joints
- Walk the elevations once or twice a year
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
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.
