Floor joint sealing near Islip
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
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.
Floor joint sealing in Islip
A working floor can rarely be closed for days on end, so we phase the work aisle by aisle or bay by bay. Tell us your site hours and access windows and we will plan around them so the rest of the operation keeps going. We work on forklift and pallet-truck routes, retail and showroom floors and joints along racking aisles, and what we’re called in for most is joint fill separating from the concrete and sealant pulled out along a truck route. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Islip is the same: the right product in a properly prepared joint.
Around smaller places such as Islip, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Islip: questions and answers
Does your area include sites such as Business Park, near Islip?
Yes. Our area takes in Islip and its surroundings, with estates and business parks such as Business Park included. A few photos and the unit address let us price the work.
Is hospital work, at somewhere like Churchill Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Why is there a gap next to the joint filler?
Separation typically comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What happens if the joint edges are damaged?
A filler needs sound edges to grip. If the arrises have spalled, we will say they need repair before filling and set out how that affects the job.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Should maintenance staff do it?
Paperwork matters too. 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 anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Islip need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We look at joint widths, edge condition and the traffic on each route.
- You get a fixed quote with the product and the phasing set out.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- We vacuum each run and prime it if the chosen product requires a primer.

Getting the site ready

Advice
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Level or flatness problems across the floor
- Structural cracking in the slab
- Unstable slabs moving under traffic
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Different surfaces, different methods
Flexible floor sealants
A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.
Saw-cut induced joints
Most of the joints in a warehouse floor are saw cuts. We clear them back to clean concrete and fill them to the depth the product calls for with a flush finish.
