Commercial sealant contractors across EC1M: what to expect
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. Site teams most often ask us about frame mastic that has hardened and come away from the wall and sanitary sealant that has gone black and patchy, across window and door perimeters, kitchen worktops and splashbacks and external facade joints.
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.

Near you in Blackfriars
We work on buildings around St Ann Blackfriars, St Mary-at-Hill and Barts Health Archives, among other places. Also close by are St Alban's Church of England Primary School (0.6 miles north-west), Mercers' School (under half a mile north-west), Bernie Spain Gardens (less than half a mile south-west) and London Nautical School (0.5 miles south-west). Blackfriars has its own railway station: London Blackfriars station. A little further out are Montfichet's Tower (less than half a mile north-east) and St Brides Crypt Museum (less than half a mile north-west). Green spaces nearby include St. James's Park Lake and Ludgate Hill.
- Local pubs include The Black Friar pub (under half a mile south-east)
Commercial premises across EC1M
From Blackfriars outwards, EC1M has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact.
Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover EC1M along with the rest of the region.
Blackfriars: Premises within reach of London Blackfriars station, under half a mile south of Blackfriars, often have busy frontages where joints are seen by everyone passing. If you have premises on more than one site, say at Grand Vitesse Industrial Estate and Southwark Bridge Business Centre, one contractor and one quote can cover both.
Surface by surface
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
After the work
Regular inspection catches problems early. Specifically:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Put external and wet-area joints on a regular inspection round
- Keep washroom and kitchen extraction working
- Brief cleaning contractors to avoid scourers and blades on sealant
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.
Quoting for work in EC1M
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- Phasing around occupants
- Distance, for remote addresses
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Approximate linear metres or a joint schedule
- Access details, including height
- The postcode of the building
- When you need the work done
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Your questions answered
Can one contractor look after sealant on all our buildings?
Yes. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you cover EC1M?
Yes. EC1M falls within our area, and the simplest way to start is to call 01277 525 020 or use the quote form.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is your work guaranteed?
Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.
Can areas stay open during the work?
We phase the work so parts of the building stay open. Tell us your site hours and access windows and we’ll plan around them.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
