Work for main contractors and building owners

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.
How we handle commercial sealant contractors in Coscote
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). We work on window and door perimeters, external facade joints and movement joints in walls and floors, and the failures we’re asked to look at most are sanitary sealant that has gone black and patchy and window and door perimeter joints that have cracked open.

A lot of what we do in Coscote is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
In and around smaller places such as Coscote, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Check sealant as part of routine building inspections
- Have extract fans checked so wet areas dry out
- Check joints after other trades have worked nearby
- Note dates and locations of sealant work for future planning
Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. It’s worth having fans checked while the sealant is fresh.
Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
When to call us in Coscote
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.
Most enquiries start with one or more of the following:
- Layers of sealant, all of them failing
- External beads that have gone brittle and cracked
- Leaks that seem to come through a sealant line
- Mouldy silicone around WCs, urinals and vanity tops
Shops and cafés around stations like Didcot Parkway station (1.5 miles north of Coscote) trade from early, so work is timed around them.

Your questions answered
Is Market Place Shopping Centre, near Coscote, within your area?
Yes. Estates, retail parks and business parks around Coscote, Market Place Shopping Centre among them, are all within reach. 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.
Is Coscote too small for you to travel to?
Not at all. Coscote is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Is failed sealant stripped out, or sealed over?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Does weather matter for sealant work?
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.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship, starting at sign-off. Looking after the joints as we advise helps them last.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Leave it or put it right?
On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. For buildings around smaller places like Coscote, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
