About commercial sealant contractors in EN10
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we will plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on floor and threshold joints, movement joints in walls and floors and washrooms and tea points, and what we are called in for most is sanitary sealant that has gone black and patchy and hardened, chalky sealant on south-facing or exposed elevations.
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.
- We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
- Next comes a diagnosis and a fixed quote.
- Before anything is cut out, we agree access, timings and sequence.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What you’ll pay
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Where commercial joints are in EN10
Commercial buildings across EN10 range from older premises altered many times to recent units on business parks. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
The South East is one of the UK’s drier regions, though outside work in EN10 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Broxbourne: If you run an office at a site such as Hilgrove Business Park, 1.3 miles south-east of Broxbourne, the sealant at reception desks, tea points and frames ages with each fit-out. Sites a few miles apart, such as Hilgrove Business Park and Brookfield Retail Park, can share one programme and one point of contact.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- The site’s rules and procedures
- Any access equipment needed
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- What the building is and how it’s used
- The postcode of the building
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or use the quote form.
Common problems we fix in EN10
In wet areas the enemy is typically mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. The fix is a new bead of anti-mould sanitary silicone.
Common reasons buildings call us in:
- Smeared sealant across finishes from a rushed job
- Layers of sealant, all of them failing
- Weathered facade sealant that no longer flexes
- Leaks that seem to come through a sealant line
Doing it in-house
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. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Surface by surface
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, and we will tell you if the detail calls for something else.
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.
Questions about EN10
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
What guarantee do you give on resealing?
Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Which site documents can you send us?
We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Could the old sealant in an older building contain asbestos?
It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.
How do you keep disruption to occupiers down?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.
