Our commercial sealant contractors service in NW3
Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on external facade joints, kitchen worktops and splashbacks and washrooms and tea points, and what we’re called in for most is wall and floor joints that have lost their seal and mouldy silicone around WCs, urinals and vanity tops.
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- 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.
What affects the price in NW3
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Commercial sealant contractors across NW3: the area picture
From Hampstead, West Hampstead and Kentish Town outwards, NW3 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. Because we cover all of it, multi-site occupiers can bring every building under one quote, with colours matched site to site where the brand needs it.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in NW3 starts with access, parking and site rules.
Hampstead: Occupiers with premises at both The Quadrant Business Centre and Regis Road Business Park could have the sealant at each handled under one quote. Offices and shops close to stations such as Finchley Road & Frognal station, under half a mile to the south-west of Hampstead, tend to be busy all day, so sealant work is planned around opening hours.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Act on the first lifting edges rather than waiting
- Add sealant to the planned maintenance inspection list
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep barriers up until the new sealant has cured
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks. Should something look amiss, you can call 01277 525 020 or email a schedule or drawings and send a picture.
Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Distance, for remote addresses
- The size and state of each joint
- The total length or number of joints
- Which sealant the job calls for
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Whether an asbestos survey exists
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or send photos by email with what you know.
Why act early?
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, and they’re where most failures begin. It shows over the following seasons rather than at handover.
What your quote should include
- The named product and why it was chosen
- Will CSCS-carded applicators be on site?
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
Surface by surface
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control.
Shop fronts and retail fit-outs
In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal, often in a colour to suit the brand finish. Colour options are confirmed with the quote.
Questions we’re asked in NW3
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
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 checks let you plan resealing before leaks or damage.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.
