Expansion joint sealing near Edgware
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
After handover, these steps help:
- Inspect exposed joints once the cold weather has passed
- Act on the first tear or lifting edge rather than waiting
- Note which joints were done, when, and with what
- Raise snow-clearing blades over deck joints where possible
Debris does more harm to joint sealant than most people realise. 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.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.
Expansion joint sealing in Edgware
If you need expansion joint sealing in Edgware, start with photographs and joint lengths. We will come and look where photographs don’t show enough, then send a fixed quote that names the sealant. You can also call 01277 525 020 or email drawings and photos to talk the joints through. If you have sealant peeling off one face of the joint and leaks through car park deck joints onto the level below, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Edgware, that means joint design, primers and backing rod as standard.
Areas such as a loading bay or car park deck in Edgware normally have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
Every job we finish is backed by a 12-month workmanship guarantee, in Edgware as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Traffic, movement and joints around Edgware
The 3 miles around Edgware take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. In London, decks, bays and service yards normally have to keep running, so joints are sealed in sections with each area handed back once cured.
If you manage units on an estate such as Mill Yard Industrial Estate, 1 mile south of Edgware, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. At places like Mill Hill Industrial Estate (1.3 miles south-east of Edgware), joints are sealed a section at a time so operations carry on. A campus such as Middlesex University, 2 miles south-east of Edgware, has long runs of movement joint in its buildings, decks and paving.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Waterproofing layers buried beneath the sealant
- Changing the joint layout or spacing of a structure
- Movement on a scale no sealant is meant to absorb

FAQs: Edgware
Do you take on jobs in Edgware where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Mill Yard Industrial Estate, by Edgware?
Yes. We cover Edgware and the area around it, including industrial estates, business parks and retail parks such as Mill Yard Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do the joint edges need to be sound before sealing?
Sound edges are essential. If they’re damaged, we’ll say so before any sealing so you’re not paying for a bead that won’t hold.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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. For a job in Edgware, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
- Make sure the joints can be reached
Request a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Related advice
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For managing agents and facilities managers
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Edgware can form part of a wider programme across Greater London.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Failed sealant in a building in Edgware can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
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.
