Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Cricklewood starts with access. Send the building rules and access times with your enquiry.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site

Expansion joint sealing for commercial buildings in Cricklewood
For movement joints in Cricklewood, photos and approximate lengths are the best start. Send them through our quote form, and we will arrange a site visit if needed. You can also give us a call on 01277 525 020 or email the details over to talk the joints through. Most enquiries involve movement joints with split or torn sealant and joints where the bead has lost adhesion, on blockwork control joints, brickwork movement joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, in Cricklewood it comes down to the same thing: the right product in a properly prepared joint.
Areas such as a loading bay or car park deck in Cricklewood typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for movement joints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Distance, for remote addresses
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Any access equipment needed
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Access details, including height
- Asbestos survey details if the building is older
- The site address and postcode
- Clear photos of the problem areas
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email the details over.
Cricklewood: questions and answers
Would you work within a site like Royal Free Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
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.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Why deal with it now?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we’ll plan around it. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Signs you need expansion joint sealing in Cricklewood
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
Any of the following is a good reason to get the joints checked over:
- Water getting into the wall through a failed joint
- Water dripping through deck or ramp joints
- Joints where the bead has lost adhesion
- Spalled or broken joint edges in floors and decks
Large sites such as Royal Free Hospital, 2.2 miles to the east of Cricklewood, have car parks, service roads and long elevations with movement joints in brick and panels.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Record the sealant used and the date in the O&M file
- Keep racking legs and heavy point loads off floor joints
- Look over external and deck joints after a hard winter
- Keep stones and debris out of open joint lines
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.
