FAQs: Whetstone
Do you cover business parks and estates near Whetstone, such as Finchley Industrial Centre?
Yes. Our area takes in Whetstone and its surroundings, with estates and business parks such as Finchley Industrial Centre included. Photos and a short description are enough for a first look.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How do we get a quote for floor joints?
A rough joint length, a few photographs and a site plan let us give a quick quote. We can visit where that helps, and you can speak to us on 01277 525 020 or send details through our quote form to arrange it.
Do you use semi-rigid filler or flexible sealant on floor joints?
It depends on the traffic and the movement. Trafficked joints on truck routes normally need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
How soon can traffic go back on the floor?
Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What the job involves on each surface
Flexible floor sealants
Where joints move more, a flexible polyurethane floor sealant is often used. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.
Retail and showroom floors
Retail joints see trolleys, footfall and scrubber-driers. We pick a filler or sealant to suit and the finish matters as much as the performance.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Cost factors for floor joints
We price every job individually. The main factors are:
- The product specified
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- Location, for remote and island sites
Pricing floor joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

For an accurate fixed quote, we need a clear picture of the site. Send us:
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
- Clear photos of the problem areas

Do you need floor joint sealing in Whetstone?
Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. That is usually where joint failure starts.
Clients normally get in touch after noticing one or more of the following:
- Cracked and crumbling joint fill
- Dock area joints that have failed first
- Drivers complaining about joints on a route
- Scruffy, dirty joint lines on a shop or showroom floor
Hospital campuses such as Finchley Memorial Hospital, 1.4 miles south of Whetstone, grow in stages, leaving movement joints wherever new blocks meet old.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We look at joint widths, edge condition and the traffic on each route.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- Each phase reopens when the product is ready for wheels, then we start the next.
Getting the site ready
- Send any specification or drawings in advance
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email drawings and photos.
Advice
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
