Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Surface by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
About our expansion joint sealing in Blacklands
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on blockwork control joints, brickwork movement joints and car park decks and ramps, and what we’re called in for most is new sealant over old, now failing and chipped joint edges on forklift routes. A specialist sealant contractor works differently from a general builder: on jobs in Blacklands, preparation and product choice get the time they need.
Rural business units around smaller places such as Blacklands often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
Every job is signed 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.

From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Several jobs near Blacklands can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000

- Make sure the joints can be reached

Questions we’re asked in Blacklands
Does a coastal location like Blacklands affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is York Road Business Centre, near Blacklands, within your area?
Yes. We cover Blacklands and the area around it, including industrial estates, business parks and retail parks such as York Road Business Centre. Send details of the unit and the work through our quote form for a quick quote.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
What causes movement joint sealant to fail?
The way it has failed normally tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you work in Blacklands?
Yes. Blacklands is in our area and the rest of East Sussex, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email us.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme. We can split the scope into urgent and planned. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
