Expansion joint sealing in Frinsted, done properly
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. If you’re dealing with movement joints with split or torn sealant and rain penetration at brick or block movement joints, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Frinsted, preparation and product choice get the time they need.
Smaller community and commercial buildings around Frinsted have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Surface by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Signs you need expansion joint sealing in Frinsted
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Look out for the following:
- Sealant peeling off one face of the joint
- Torn sealant in brick or block movement joints
- Spalled or broken joint edges in floors and decks
- Debris jammed in movement joints
A campus such as Canterbury Christ Church University, 1.5 miles south-west of Frinsted, has long runs of movement joint in its buildings, decks and paving.

What else we do in Frinsted
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Joints too narrow for the movement, which need redesigning by the engineer
- Concrete or masonry repairs along the arrises
- Waterproofing layers buried beneath the sealant
If in doubt, ring 01277 525 020 or email us and we will say what we think.
What we seal
- Precast concrete panel joints
- Brickwork movement joints
- Cladding panel joints
- Blockwork control joints
- Car park decks and ramps
- Podiums and floor movement joints
Leave it or put it right?
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Around Frinsted, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- Colours chosen to suit frames, cladding or finishes where possible

Frinsted: questions and answers
Does your area include sites such as Kent Science Park, near Frinsted?
Yes. Estates, retail parks and business parks around Frinsted, Kent Science Park among them, are all within reach. Photos and a short description are enough for a first look.
Must our site in Frinsted stop work while the joints are done?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
What happens if it rains on the day?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.
Is Frinsted in your area?
Yes. Frinsted is in our area. For a quote, phone 01277 525 020 or email a schedule or drawings.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What if the joint edges are damaged?
The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first so you’re not paying for a bead that won’t hold.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Frinsted need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.
