Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Suspect materials that need testing and specialist removal
- Faulty windows rather than failed perimeter sealant
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Sealant applicators in Rowley Green
On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike. We work on window and door perimeters, washrooms and tea points and kitchen worktops and splashbacks, and what we are called in for most is sanitary sealant that has gone black and patchy and messy, uneven beads from earlier work that let the building down. A specialist sealant contractor works differently from a general builder: on jobs in Rowley Green, preparation and product choice get the time they need.
A lot of what we do in Rowley Green is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Around Rowley Green, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

What else we do in Rowley Green
Different surfaces, different methods
Washrooms and toilets
Mould that has grown into washroom sealant can’t typically be cleaned out. The lasting answer is removal, preparation and a new sanitary bead.
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.
What sets the cost
To price the job, we consider:
- Induction, permit and paperwork requirements
- Access and working height
- Backing rod, priming and other preparation
- How much existing material needs removing
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Access details, including height
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or send photos by email.

Rowley Green: questions and answers
Do you cover business parks and estates near Rowley Green, such as Elstree Trade Park?
Yes, sites like Elstree Trade Park are within our area, along with the rest of Rowley Green. A few photographs and the unit address let us price the work.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. We can work to your instruction process and site rules.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is it OK to apply fresh sealant over existing beads?
Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Don’t let cleaning or traffic back on before the cure time is up
- Deal with small splits before they become leaks
- Check joints after other trades have worked nearby
- Make sure ventilation in wet areas is switched on and working
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.
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.
