Our commercial sealant contractors service in W1K
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on movement joints in walls and floors, washrooms and tea points and kitchen worktops and splashbacks, and what we’re called in for most is smeared sealant across finishes from a rushed job and greasy, split joints in a kitchen or tea point.
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you.
- 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.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
How we quote
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Work to your specification and the manufacturer’s guidance
- Our applicators hold CSCS cards
- Colours chosen to suit frames, cladding or finishes where possible

Commercial sealant contractors across W1K: the area picture
In W1K, much commercial sealant work follows refits in shops, offices and hotels in places such as Marylebone, Mayfair and Burlington Estate. Where the joint is on show, a colour that suits the finish is part of the job.
We work across Greater London and the South East counties, and every job in W1K starts with access, parking and site rules.
Mayfair: Units at places like Brunswick Centre (to the north-east of Mayfair) are refitted as brands change, and the joints have to suit each new scheme. Refits at hotels like The Chesterfield Hotel, under half a mile south of Mayfair, bring joints at vanity tops, bars and reception desks that guests see every day.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Faulty windows rather than failed perimeter sealant
- A dripping trap, valve or pipe behind a fitting
Why it fails
Washrooms and kitchens wear sealant out in their own way. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.
Things that typically lead to an enquiry:
- Messy, uneven beads from earlier work that let the building down
- Black mould through washroom sealant that won’t clean off
- Hardened, chalky sealant on south-facing or exposed elevations
- Water staining near frames, panels or ceilings
Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. We plan around the access windows the store gives us.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price.
Leave it or put it right?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in.
What your quote should include
- Their pre-qualification and accreditations
- Will CSCS-carded applicators be on site?
- Their public liability cover
- What site paperwork they can supply
Questions we’re asked in W1K
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you work in W1K?
Yes. We take on work across W1K, and the same phone number covers every area.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
What do you need from us to 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.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Will the building have to shut during the work?
It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we will work around it.
