About our floor joint sealing in How Wood
Most industrial slabs are divided into panels with saw cuts and day joints, and every one of those joints is an exposed edge under hard wheels. We fill or seal them with a product matched to the traffic and the movement, so the arrises are supported and grit stays out. If you’re dealing with joint fill separating from the concrete and saw-cut joints left open and packed with grit, we can put it right, on forklift and pallet-truck routes, retail and showroom floors and loading bays alike. For commercial sealant work in How Wood, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around places the size of How Wood, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
Every job we finish is backed by a 12-month workmanship guarantee, in How Wood as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from How Wood clients
Do you take on work at healthcare sites like Kingsley Green 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.
Does your area include sites such as North Orbital Commercial Park, near How Wood?
Yes. Our area takes in How Wood and its surroundings, with estates and business parks such as North Orbital Commercial Park included. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you fill joints where the arrises have spalled?
Filling against broken edges doesn’t last. We’ll tell you if the joint edges need repairing first and set out how that affects the job.
Is the floor joint work guaranteed?
Our workmanship carries a 12-month guarantee and the work is covered by public liability insurance.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For bigger or phased jobs, we will set out a timescale with the quote.
Why has the filler pulled away from one side?
Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.
What happens if it’s left?
Dirt and spillage gather in open joints, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Filled joints are far simpler to keep clean. In a smaller place such as How Wood, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
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.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Plan for a top-up on newer floors
- Keep photos of joints that look like they’re failing
- Put loading bays at the top of the list
- Walk the main routes and inspect joint lines on a regular cycle
Problems inside the 12-month guarantee period are ours to put right. After that, a check before your busiest period keeps small repairs small.
Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it and that takes longer and closes areas for longer.
Common problems we fix in How Wood
Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge and those knocks chip the edge apart bit by bit.
Clients typically get in touch after noticing something like this:
- Grimy joint lines spoiling a showroom floor
- Saw-cut joints left open and packed with grit
- A gap opening alongside old joint filler
- A rough ride across broken joints
On a site such as North Orbital Commercial Park, which lies north-east of How Wood, the movement joints are in car park slabs, paving and building elevations.
Questions to ask before you book
- Who will actually carry out the work
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- Whether old or failed sealant will be cut out, not overlaid
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of How Wood is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- First, the zones and order of work are agreed with you.
- Any joints with broken edges are flagged before work starts.
- Failed material and debris are removed and the joint cleaned.
- We fill the joints with the agreed product, finished level.
- Each area is handed back when ready for traffic.
Preparing the site
- Let building users know which areas are affected
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work

Advice
Different surfaces, different methods
Construction joints
Where a day joint crosses a truck route, its edges take heavy punishment. We look at how much they are moving before choosing the treatment.
Forklift and pallet-truck routes
Open route joints are hard on equipment and drivers. Filling them gives a smoother run and saves the edges.
Building owners, agents and FMs in How Wood
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, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
