Your questions answered
Can you work at a site such as Verulam Industrial Estate, by St Stephens?
Yes. Our area takes in St Stephens and its surroundings, with estates and business parks such as Verulam Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is St Stephens too small for you to travel to?
No. Places such as St Stephens are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How long before trucks can use the joints?
Cure times vary with the product and how cold the slab is. We’ll give you a time for each zone before we start.
Why has the filler pulled away from one side?
On newer slabs, the concrete keeps shrinking after the joints are filled, so a semi-rigid filler can part from one face. It is normally dealt with by topping up.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes a day for smaller units, with bigger warehouse floors programmed over several visits. For bigger or phased jobs, we will set out a timescale with the quote.
Floor joint sealing in St Stephens, done properly
We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. If you’re dealing with drivers complaining about joints on a route and untidy open joints in a retail unit, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in St Stephens, preparation and product choice get the time they need.
Around St Stephens, most floor and movement joint jobs are single buildings or yards. Getting widths, depths and traffic details up front means one visit, not two.
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.

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Why act early in St Stephens
Painting or coating straight over joints rarely lasts. The joints have to be filled or sealed as joints before or alongside any coating work. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
A quote for floor joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What you get with us
- One contact handling all your sites
- Specification-led, product-correct work
- Fixed quotes based on photographs, drawings or a visit
- A Constructionline member, so easy to vet

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near St Stephens can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We look at joint widths, edge condition and the traffic on each route.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- 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.
- Each phase reopens when the product is ready for wheels, then we start the next.
Preparing the site
- Warn occupants and staff about the work
- Tell us which areas need to stay in use
- Send your site hours and access windows
Getting a fixed quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Common problems we fix in St Stephens
Loading bay joints are exposed to wind, wet tyres and bigger temperature swings, as well as the tightest turning loads. They are often the first on a site to break down.
These are often picked up first by site or facilities staff:
- A rough ride across broken joints
- Untidy open joints in a retail unit
- Cracked and crumbling joint fill
- Broken arrises where pallet trucks cross
Hospitals like St Albans City Hospital (1.2 miles north of St Stephens) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Questions to ask before you book
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
- How joint depth will be controlled
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Broken concrete either side of the joint
- Cracks across panels caused by settlement or overload
- A floor that is out of level for the racking or trucks
If you’re not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
