How we handle floor joint sealing in Harold Hill
Mastic Doctor has worked on joints in commercial buildings for over 20 years. Our CSCS-carded applicators follow your site induction and rules, and the business is CHAS accredited and a Constructionline member holding public liability insurance. Completed joints come with a 12-month guarantee on our workmanship. We work on loading bays, forklift and pallet-truck routes and retail and showroom floors, and the usual reasons a site gets in touch are filler that has parted from one face and failing joints at loading bays and dock doors. Most enquiries from Harold Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Around Harold Hill, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Why it’s worth doing now in Harold Hill
While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. In Harold Hill, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Unstable slabs moving under traffic
- Structural cracking in the slab
- A failing floor coating, which is a flooring contractor’s job
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.

- Backing rod, priming and other preparation

We don’t publish prices, since every building and every scope is different. Call for a quote.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- Where the site is, with the postcode
- What the building is and how it’s used
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Traffic, movement and joints around Harold Hill
London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures.
Hospitals like Victoria Hospital, 2.6 miles to the south-west of Harold Hill, have multi-storey or surface car parks whose joints carry vehicles round the clock. For buildings at a park such as Warley Hill Business Park (2.8 miles east of Harold Hill), brick and panel movement joints are easy to forget until one leaks. Centres like The Mercury Mall (to the south-west of Harold Hill) have mall floors and service decks whose joints carry steady traffic.

Other services in Harold Hill
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from a day for one loading bay to several days for a large floor, split into phases. 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.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- The area is handed back once it has cured enough to take traffic.
Before we start on site
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
- Warn occupants and staff about the work

Advice
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
Questions about Harold Hill
Would you work within a site like Victoria 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.
Do you cover business parks and estates near Harold Hill, such as Warley Hill Business Park?
Yes, sites like Warley Hill Business Park are within our area, along with the rest of Harold Hill. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How soon can traffic go back on the floor?
The wait is set by the product’s cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.
How long does a job like this take?
It depends on the scope, but the work normally takes anything from a day for one loading bay to several days for a large floor, split into phases. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you repair broken joint edges?
Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first and set out how that affects the job.
Why is there a gap next to the joint filler?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.
