Commercial mastic work in St John Street area
Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind. We look before we quote and tell you plainly if sealant won’t solve it. We work on external facade joints, washrooms and tea points and window and door perimeters, and what we’re called in for most is sanitary sealant that has gone black and patchy and greasy, split joints in a kitchen or tea point. Facilities teams, main contractors and managing agents in St John Street area tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In an occupied building in St John Street area, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

Related advice
Should maintenance staff do it?
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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
St John Street area: questions and answers
Will our hotel in St John Street area need to close for the work?
Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.
Will you take on work at estates like Osney Mead Industrial Estate, close to St John Street area?
Yes, sites like Osney Mead Industrial Estate are within our area, along with the rest of St John Street area. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
How do you keep disruption to occupiers down?
It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.
How is commercial sealant work priced?
The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Work for main contractors and building owners
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Signs you need commercial sealant contractors in St John Street area
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.
These are often picked up first by site or facilities staff:
- Smeared sealant across finishes from a rushed job
- Movement joints packed with grit and debris
- Frame sealant that has cracked, shrunk or pulled away
- Mouldy silicone around WCs, urinals and vanity tops
Premises within reach of Oxford station (to the south-west of St John Street area) often have busy frontages where joints are seen by everyone passing.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Can the work be phased to keep areas open?
- What site paperwork they can supply
- Their pre-qualification and accreditations
After the work
Keep the joints in good shape with a few simple steps:
- Have extract fans checked so wet areas dry out
- Ask fit-out and M&E contractors to report any sealant they disturb
- Put external and wet-area joints on a regular inspection round
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. If that happens, ring 01277 525 020 or send photos by email and we’ll price putting it right.
Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We will tell you which sealant joints need doing first and which can wait.
Different surfaces, different methods
Fire-rated seals where specified

Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.
