How we handle commercial sealant contractors in Fitzrovia
Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind 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 nobody pays for a reseal that can’t hold. Site teams most often ask us about black mould through washroom sealant that won’t clean off and window and door perimeter joints that have cracked open, on washrooms and tea points, movement joints in walls and floors and floor and threshold joints. Whoever orders the work in Fitzrovia, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
We price commercial jobs in Fitzrovia from photographs, drawings or a site visit, and the scope is set out in writing.
For managing agents and FMs looking after premises in Fitzrovia, access is usually the first question: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How the job changes by surface
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.
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we’ll say so before sealing.

What else we do in Fitzrovia
When to call us in Fitzrovia
If sealant tears through its centre, it has failed cohesively. Usually the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds, so width, depth and product are checked before we quote.
Most enquiries start with something like this:
- Smeared sealant across finishes from a rushed job
- Window and door perimeter joints that have cracked open
- External beads that have gone brittle and cracked
- Expansion joints with the sealant torn out
A unit on an estate like Roman Way Industrial Estate (1.7 miles north-east of Fitzrovia) typically has an office front, a trade counter and staff facilities with joints of their own.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Questions about Fitzrovia
Do hotels near Fitzrovia have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Will you take on work at estates like Roman Way Industrial Estate, close to Fitzrovia?
Yes. Our area takes in Fitzrovia and its surroundings, with estates and business parks such as Roman Way Industrial Estate included. A few photographs and the unit address let us price the work.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
What site paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Fitzrovia can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Agree which areas must stay open
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Walls or slabs moving more than any sealant can take
- Broken glass or blown double-glazed units
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Surfaces we seal
- Floor and threshold joints
- Kitchen worktops and splashbacks
- Washrooms and tea points
- External facade joints
- Window and door perimeters
- Movement joints in walls and floors
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Respect the cure time before reopening an area
- On pre-2000 buildings, share the asbestos information before work starts
- Report cracked or peeling sealant early
Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. Your maintenance team can look at extract fans at the same time.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
