Expansion joint sealing for commercial buildings in Preston
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on blockwork control joints, brickwork movement joints and cladding panel joints, and what we’re called in for most is layers of sealant in a movement joint and rain penetration at brick or block movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Preston, that means joint design, primers and backing rod as standard.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- A joint that has to be widened or re-detailed before it can work
- Concrete or masonry repairs along the arrises
Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly.
Joints and surfaces we work on
- Brickwork movement joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Blockwork control joints
- Car park decks and ramps
- Cladding panel joints
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Location, for remote and island sites
- Site requirements such as inductions and permits
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
However big the job, the same details help:
- The postcode of the building
- Specification clauses that apply
- The asbestos register, for older buildings
- When you need the work done
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Surface by surface
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in.
Expansion joint sealing in Preston: the local picture
The 3 miles around Preston take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.
Large sites such as Northwick Park Hospital, 1.2 miles to the west of Preston, have car parks, service roads and long elevations with movement joints in brick and panels. Across sites such as Stadium Retail Park, 0.9 miles south-east of Preston, floor and movement joints can be sealed in phases so units keep working. University campuses such as Westminster University (1.3 miles west of Preston) have car parks, paved walkways and building elevations with movement joints.
Preston is about 1 mile north of Wembley, in Greater London. We cover commercial sites throughout Preston, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, including Preston. Sites around London have their own page, about 10 miles away.
Work on movement joints is covered throughout HA9, HA3 and HA0. Among the streets we cover are Quad Road, Tower Lane and The Avenue, and sites on any of them can send details for a fixed quote. We also cover Wembley (1 mile south), Wembley Park (1 mile south-east), Kingsbury (1 mile north-east), Queensbury (1 mile north) and Mapesbury (1 mile south-east) for movement joints. Bigger towns within reach include London (10 miles south-east), City of Westminster (7 miles south-east), Marylebone (7 miles south-east), Kensington (6 miles south-east), St Pancras (8 miles east) and Shoreditch (10 miles east).
What’s near Preston
We work on buildings around Windermere pub, Preston Manor School and Preston Park. The nearest railway station is South Kenton station, about 0.6 miles west. A little further out are London Designer Outlet (1.1 miles south-east) and Kodak Museum (2.6 miles north-west). Open spaces near Preston include Masons Field and Castlebar Hill.
What happens if it’s left?
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. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In Preston, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- 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.
Getting the site ready
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Agree which areas must stay open

Common questions from Preston clients
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on work at estates like East Lane Business Park, close to Preston?
Yes. We cover Preston and the area around it, including industrial estates, business parks and retail parks such as East Lane Business Park. Photos and a short description are enough for a first look.
What will the job cost?
We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Maintenance after handover
For the best life from the joints:
- Treat a small split as a warning, not a cosmetic issue
- Note which joints were done, when, and with what
- Clear dirt from joint lines during routine cleaning
- Inspect movement joints alongside other routine building checks
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.
