Floor joint sealing for commercial buildings in Southsea
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. If you are dealing with old filler gone hard, cracked or loose and unfilled floor joints collecting dirt and grit, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Southsea is the same: the right product in a properly prepared joint.
Car parks and yards in towns like Southsea take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why it’s worth doing now in Southsea
Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why appoint us
- Clear, fixed quotes
- One phone line for London, the South East and Scotland
- 12-month guarantee on workmanship
- Specification-led, product-correct work

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. If you have more than one building in Southsea, they can often be done on the same visit. Tell us when the building is open and we will plan to suit.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- 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 sucked out of the joint and a primer used if the product data sheet asks for one.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- We tell you when each zone can carry trucks again and move on to the next.
Getting the site ready
- Make sure the joints can be reached
- Agree which areas must stay open
- Share your working hours and any access restrictions

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Aftercare for building managers
A few simple habits keep the new joints working:
- Tell us about strong cleaning chemicals before we quote
- Keep photographs of joints that look like they’re failing
- Put loading bays at the top of the list
- Stop forks and pallets being dragged across joints
If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.
Every vehicle on a busy aisle hits a damaged joint. Early treatment protects wheels, loads and drivers as much as the floor.
Questions we are asked in Southsea
Would you work within a site like St James Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can being near the sea in Southsea affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Is Southsea in your area?
Yes. We take on work across Southsea, and the same phone number covers every area.
Is the floor joint work guaranteed?
There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Quoting for work in Southsea

Pricing floor joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
What to include in your enquiry
However big the job, the same details help:

- Photos of the joints, close up and from further back
- The product your specification calls for
- The type of building and who uses it
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
