Our commercial sealant contractors service in PO5
Sometimes a split bead is a symptom rather than the cause. A leak near a frame edge can start in the frame, the cill or the cavity while a movement joint that keeps tearing may simply be too narrow for the job. We look before we quote and tell you plainly if sealant won’t solve it. We work on kitchen worktops and splashbacks, washrooms and tea points and external facade joints, and what we are called in for most is mouldy silicone around WCs, urinals and vanity tops and frame sealant that has cracked, shrunk or pulled away.
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a few hours for one area, or a planned series of visits across a bigger building, and we clear our waste as we work.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What affects the price in PO5
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Local landmarks in Southsea
In Southsea, that means premises near St Edmund's Catholic School, Mayville High School and St Margaret of Scotland. Other local landmarks include Craneswater Junior School (under half a mile north-west) and The Festing pub (less than half a mile north). For rail, the closest station is Fratton station, roughly 0.8 miles north of the centre. Other landmarks nearby include St. Mary's Hospital (1 mile north) and Southsea Castle (1 mile south-west). For a walk, there’s Milton Locks.
Commercial premises across PO5
Commercial buildings across PO5 range from older premises altered many times to recent units on business parks. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
We work across Greater London and the South East counties, so jobs in PO5 are planned with access, loading and parking in mind. PO5 includes coastal places, where facades, frames and external slabs take more weather than inland. We take that exposure into account when choosing the product.
Southsea: Occupiers with premises at both The Bridge Shopping Centre and Copnor Bridge Business Centre could have the sealant at each handled under one quote. Offices and shops close to stations such as Fratton station, 0.8 miles to the north of Southsea, tend to be busy all day, so sealant work is planned around opening hours.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Structural cracks or movement the joints weren’t designed for
- Suspect materials that need testing and specialist removal
- A dripping trap, valve or pipe behind a fitting
Different surfaces, different methods
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.
Aftercare for building managers
After handover, these steps help:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Make sure ventilation in wet areas is switched on and working
- Don’t let cleaning or traffic back on before the cure time is up
- Log reseals in the O&M or maintenance records
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.
Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.
What affects the price in PO5
Before we quote, we look at:
- The product specified
- Whether the work must be split into stages
- Distance, for remote addresses
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Your programme or deadline
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- Access details, including height
For a fixed quote, give us a call on 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
Common problems we fix in PO5
When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Any of the following is a good reason to get the joints checked over:
- Movement joints packed with grit and debris
- Frame mastic that has hardened and come away from the wall
- Leaks that seem to come through a sealant line
- Sanitary sealant that has gone black and patchy
Common questions from PO5 clients
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What site paperwork can you provide?
Send your site requirements with the enquiry, and the paperwork is confirmed with the quote. For older buildings we will ask for the asbestos register, plus your site induction rules.
Is your work guaranteed?
Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.
What about asbestos in old mastic?
On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
