Expansion joint sealing near North Kensington
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. In North Kensington, 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.
- First, the joints are inspected for width, movement and the type of failure.
- 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, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Confirm the product named in the specification

About our expansion joint sealing in North Kensington
For movement joints in North Kensington, photographs and approximate lengths are the best start. We will come and look where photographs don’t show enough before issuing a fixed quote. You can also give us a call on 01277 525 020 or send photos by email to talk the joints through. If you’re dealing with expansion joints split through the centre of the bead and hardened, cracked sealant on exposed facades, we can put it right, on car park decks and ramps, blockwork control joints and brickwork movement joints alike. Looking for mastic applicators who cover North Kensington? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, 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.

Commercial clients in North Kensington
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Access and working height
Pricing movement joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- Clear photographs of the problem areas
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
- The site address and postcode
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Waterproofing layers buried beneath the sealant
- Movement on a scale no sealant is meant to absorb
- Proprietary pre-formed expansion joint systems
Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Brief car park operatives to protect joint lines during winter clearance
- Treat a small split as a warning, not a cosmetic issue
- Plan racking layouts so feet don’t land on a joint
- Look over external and deck joints after a hard winter
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Floors, slabs and movement joints in North Kensington
In London, decks, bays and service yards usually have to keep running, so joints are sealed in sections with each area handed back once cured. At least three named trading, business or retail sites lie within about 3 miles of North Kensington. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Large sites such as St Charles' Hospital (to the south-east of North Kensington) have car parks, service roads and long elevations with movement joints in brick and panels.

Warehouse floors on estates like Latimer Industrial Estate (to the south-west of North Kensington) carry pallet trucks and forklifts over every saw-cut joint.

Your questions answered
Will you take on work at estates like Latimer Industrial Estate, close to North Kensington?
Yes. We cover North Kensington and the area around it, including industrial estates, business parks and retail parks such as Latimer Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
What’s the difference between an expansion joint and a movement joint?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available, and we’ll plan the phasing around it.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
