Commercial sealant contractors in EC2M: how it works
Sometimes a split bead is a symptom rather than the cause. A leak near a frame edge can start in the frame, the cill or the cavity while a movement joint that keeps tearing may simply be too narrow for the job. We look before we quote and tell you plainly if sealant won’t solve it, so budgets go where they’ll do some good. We work on floor and threshold joints, external facade joints and movement joints in walls and floors, and what we are called in for most is window and door perimeter joints that have cracked open and a top-up bead over failed sealant, now lifting.
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, and a site visit is booked where it helps.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.

Shops, offices and hotels in EC2M
Across EC2M, from EC2M to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact, with colours matched site to site where the brand needs it.
The South East is one of the UK’s drier regions, though outside work in EC2M still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
City of London: If you have premises on more than one site, say at Southwark Bridge Business Centre and Grand Vitesse Industrial Estate, one contractor and one quote can cover both. Shopping centres and retail parks such as Brunswick Centre, 1.5 miles north-west of City of London, see a steady turnover of shop fits, each leaving joints where colour and finish matter.
Different surfaces, different methods
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
Shop fronts and retail fit-outs
Retail work usually has to fit around trading. Tell us your trading hours and access windows and we’ll plan around them, phasing areas so the shop floor stays usable.
Why act early?
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. You notice the difference years later, not on the day.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- How the existing material will be dealt with
- How the joint faces will be prepared and primed
- How long is the guarantee, and what does it include?
What we are called out for in EC2M
The wrong sealant in the wrong place is a common cause of early failure. 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 will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
What tends to prompt an enquiry:
- Hardened, chalky sealant on south-facing or exposed elevations
- Damp patches where an external joint has failed
- Layers of sealant, all of them failing
- Expansion joints with the sealant torn out
What affects the price in EC2M
What shapes the price:
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Distance, for remote addresses
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- Approximate linear metres or a joint schedule
- Clear photographs of the problem areas
- Asbestos survey details if the building is older
- The type of building and who uses it
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send details through our quote form.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
We work for building owners and managing agents on everything from one building to a spread of sites around EC2M. Several sites can go on one quote, which keeps the paperwork simple.
EC2M: questions and answers
Can one contractor look after sealant on all our buildings?
Yes. We take on runs of jobs across portfolios as well as single sites.
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.
How do we get a quote?
Send what you have, even a few photos and rough lengths. We follow up with questions or a visit where needed, then a fixed quote.
How do you keep disruption to occupiers down?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Is failed sealant stripped out, or sealed over?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Is EC2M in your area?
Yes. Sites across EC2M are covered, and the same phone number covers every area.
