On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. 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.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
- Share your working hours and any access restrictions

Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out.

Common questions from North Wembley clients
Do you take on jobs in North Wembley where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Do you cover business parks and estates near North Wembley, such as East Lane Business Park?
Yes. Our area takes in North Wembley and its surroundings, with estates and business parks such as East Lane Business Park included. A few photos and the unit address let us price the work.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
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.
Can a joint be sealed if the edges are broken?
Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.
Do you cover North Wembley?
Yes. We cover North Wembley. For a quote, call the office on 01277 525 020 or email us.

- The site’s rules and procedures
- How much existing material needs removing
- Backing rod, priming and other preparation
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Anything awkward about access or site hours

- Your programme or deadline
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email a schedule or drawings.

What the job involves on each surface
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement, and tell you if edges need repairing first.
When to call us in North Wembley
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
It’s worth sending us details if you spot any of the following:
- Debris jammed in movement joints
- Water dripping through deck or ramp joints
- Chipped joint edges on forklift routes
- Hardened, cracked sealant on exposed facades
Across sites such as Stadium Retail Park (1.1 miles east of North Wembley), floor and movement joints can be sealed in phases so units keep working.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Can the work be phased to keep areas open?
- How the existing material will be dealt with
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- A joint that has to be widened or re-detailed before it can work
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Joints and surfaces we work on
