Warehouse floors and decks around Gillette Corner
Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager. At least three named trading, business or retail sites lie within about 3 miles of Gillette Corner. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Across sites such as Great West Trading Estate (less than half a mile east of Gillette Corner), floor and movement joints can be sealed in phases so units keep working. A campus such as University of West London (Brentford Campus), 0.7 miles to the north-east of Gillette Corner, has long runs of movement joint in its buildings, decks and paving. A healthcare site such as West Middlesex Hospital, 0.8 miles south of Gillette Corner, depends on car parks, ramps and service yards whose joints take traffic all day.

Expansion joint sealing in Gillette Corner, done properly
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. Most enquiries involve leaks through car park deck joints onto the level below and sealant peeling off one face of the joint, across precast concrete panel joints, blockwork control joints and car park decks and ramps. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Gillette Corner, 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 stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Surface by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.
Site staff or a sealant specialist?
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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Leave it or put it right?
Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s typically not far behind. Where it helps, we quote both options. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Common questions from Gillette Corner clients
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. We allow for the ULEZ, which covers every borough
Can you take on a job at a hospital such as West Middlesex Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Why do our movement joints keep failing?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Commercial clients in Gillette Corner
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Keeping the joints sound
After handover, these steps help:
- Act on the first tear or lifting edge rather than waiting
- Look over external and deck joints after a hard winter
- Record the sealant used and the date in the O&M file
- Inspect movement joints alongside other routine building checks
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can speak to us on 01277 525 020 or send photos by email and send a picture.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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 and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Point out parking and an unloading spot
- Have the specification and drawings to hand
