Floor joint sealing in Fratton
Mastic Doctor has worked on joints in commercial buildings for over 20 years. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. We work on saw-cut induced joints, retail and showroom floors and construction joints, and the usual reasons a site gets in touch are scruffy, dirty joint lines on a shop or showroom floor and a gap opening alongside old joint filler. Looking for mastic applicators who cover Fratton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around places the size of Fratton, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Common questions from Fratton clients
Is hospital work, at somewhere like St James Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Our building in Fratton is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you phase floor joint work around operations?
Usually only the zone we are working in has to close. Each zone reopens when the product can take traffic and the next zone follows.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Other services in Fratton
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Keep trucks off new joints until we say they’re ready
- Photograph any joint that starts to chip
- Keep grit out of unfilled joints in the meantime
- Make joint checks part of your floor inspections
On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. That is common and is typically dealt with by topping up once the slab has settled down in the majority of cases.
Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first, with more downtime and more disruption.
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Damaged or worn floor coatings and screeds
- A floor that is out of level for the racking or trucks
- Slab panels that rock or move under load
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Where we work in Fratton
- Saw-cut induced joints
- Loading bays
- Joints along racking aisles
- Forklift and pallet-truck routes
- Retail and showroom floors
- Construction joints
When to call us in Fratton
Unfilled joints soon pack with grit, shrink-wrap scraps and pallet splinters. That debris is hard and levers at the edges as wheels pass so the arrises break sooner.
Clients usually get in touch after noticing one or more of the following:
- Joint edges breaking up under truck wheels
- A rough ride across broken joints
- Loading bay joints breaking down
- Filler that has parted from one face
Across sites such as Copnor Bridge Business Centre, 0.6 miles to the north-east of Fratton, floor and movement joints can be sealed in phases so units keep working.
What your quote should include
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
- Can the work be phased to keep areas open?
Leave it or put it right?
Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, which nobody budgets for. A properly filled joint smooths the route. For buildings in places like Fratton, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- Constructionline member for supplier checks
- Products installed to the manufacturer’s instructions
- CHAS accredited
- Joints cleaned back to sound surfaces
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Traffic, movement and joints around Fratton
The sea is no more than about 2 miles from Fratton. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Fratton is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
In a school such as Penhale Infant School & Nursery, movement joints in brick, block and hall floors tend to be forgotten until they leak. Large sites such as St James Hospital, 1.2 miles to the east of Fratton, have car parks, service roads and long elevations with movement joints in brick and panels.
