Floor joint sealing for Harrow sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Floor joint sealing in Harrow, done properly
A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Tell us your site hours and access windows and we’ll plan around them so the rest of the operation keeps going. We work on loading bays, construction joints and joints along racking aisles, and what we are called in for most is loading bay joints breaking down and flexible sealant torn out by wheels. One point of contact handles commercial sealant work in Harrow from the first photos to the final walk-round, whether it’s one building or several.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the job changes by surface
Construction joints
Day joints on busy routes are prone to edge damage. We look at how much they are moving before choosing the treatment.
Loading bays and dock areas
At loading bays, product choice has to suit the loads, the temperature and the wet. Phasing is planned around your delivery schedule.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
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.
Quoting for work in Harrow
A fixed quote reflects the actual work. It allows for:
- Whether the work must be split into stages
- How much there is to seal
- Induction, permit and paperwork requirements
- How accessible the joints are
A quote for floor joints depends on how many there are, their condition and the access. Call for a quote.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Approximate linear metres or a joint schedule
- Any specification or named product
- The postcode of the building
- The type of building and who uses it
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- A floor that rocks at the joints, which needs a structural fix
- Structural cracking in the slab
- Uneven floors that need grinding or levelling
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Surfaces we seal
- Forklift and pallet-truck routes
- Construction joints
- Loading bays
- Retail and showroom floors
- Saw-cut induced joints
- Joints along racking aisles
FAQs: Harrow
Can you work at a site such as Harrovian Business Village, by Harrow?
Yes. We cover Harrow and the area around it, including industrial estates, business parks and retail parks such as Harrovian Business Village. Photos and a short description are enough for a first look.
Do you take on jobs in Harrow where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is it normal for joint filler to separate?
It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.
Do you repair broken joint edges?
We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling, so nothing is filled that won’t hold.
When can forklifts run over new joint filler?
Cure times vary with the product and the conditions. We will give you a time for each zone before we start.

Less than 3 miles from Harrow there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.

How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- We tell you when each zone can carry trucks again and move on to the next.
