Your questions answered
Does a hotel in Marks Gate need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is Grove Farm Retail Park, near Marks Gate, within your area?
Yes. Estates, retail parks and business parks around Marks Gate, Grove Farm Retail Park among them, are all within reach. A few photos and the unit address let us price the work.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we will plan around them.
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.
Do you work for facilities managers and managing agents?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. Tell us how you issue work and we’ll fit in.
How is commercial sealant work priced?
Send what you have, even a few photos and rough lengths. Questions or a site visit follow where needed, and then a fixed quote for the agreed scope.
Sealant applicators in Marks Gate
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. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on external facade joints, washrooms and tea points and window and door perimeters, and the failures we are asked to look at most are water staining near frames, panels or ceilings and shrunken sealant along kitchen worktops and splashbacks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Marks Gate, preparation and product choice get the time they need.
Multi-site clients with buildings in and around Marks Gate can put several sites on one programme, so standards and paperwork match across every site.
Around Marks Gate, 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 by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Commercial clients in Marks Gate
We work for building owners and managing agents on everything from one building to a spread of sites around Marks Gate. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Common problems we fix in Marks Gate
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, so periodic inspection matters more than any date on a schedule.
What tends to prompt an enquiry:
- Mouldy silicone around WCs, urinals and vanity tops
- Window and door perimeter joints that have cracked open
- Earlier reseals applied straight onto the failed bead
- Damp patches where an external joint has failed
Offices and shops close to stations such as Chadwell Heath station (to the south of Marks Gate) tend to be busy all day, so sealant work is planned around opening hours.

Why it’s worth doing now in Marks Gate
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

How the job changes by surface
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.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Water from a services leak rather than a joint
- Faulty windows rather than failed perimeter sealant
- Cracking that needs a structural engineer to look at it
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Movement joints in walls and floors

Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Marks Gate can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- 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.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Share the asbestos register for older buildings
- Let building users know which areas are affected
