How commercial sealant contractors works in PO9
Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on washrooms and tea points, floor and threshold joints and external facade joints, and what we’re called in for most is mouldy silicone around WCs, urinals and vanity tops and damp patches where an external joint has failed.
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out.
- 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.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
What you will pay
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Why appoint us
- Colour agreed before work starts
- One number for every site we cover
- Products installed to the manufacturer’s instructions
- Public liability insurance in place

Where commercial joints are in PO9
Commercial buildings across PO9 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.
Around the motorway corridors of the South East, business parks and industrial estates are common, and PO9 is part of the area we cover. On the coastal side of PO9, sea-facing elevations normally show failed joints first.
Havant: A hotel such as The Bear Hotel (0.9 miles south of Havant) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Premises within reach of Havant station (to the south of Havant) often have busy frontages where joints are seen by everyone passing.
Surface by surface
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, and we will tell you if the detail calls for something else.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Check sealant as part of routine building inspections
- Look at the sealant around anything that has been moved or replaced
- Report cracked or peeling sealant early
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.
Cost factors for sealant joints
A fixed quote reflects the actual work. It takes account of:
- Location, for remote and island sites
- Removal of failed or old sealant
- Any access equipment needed
- The total length or number of joints
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- When you need the work done
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email us to discuss it first.
What happens if it’s left?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next. Resealing while only the sealant has failed keeps the job small.
What your quote should include
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
- How joint depth will be controlled
- What level of public liability insurance do they hold?
Why it fails
A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.
Things that normally lead to an enquiry:
- Black mould through washroom sealant that won’t clean off
- Untidy joints in a reception, shop floor or lobby
- Water staining near frames, panels or ceilings
- A top-up bead over failed sealant, now lifting
Questions we are asked in PO9
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Is it OK to apply fresh sealant over existing beads?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.
How is commercial sealant work priced?
Photos, drawings or a schedule of the joints are typically enough to start through our quote form. Where we need to see it, we will arrange a site visit, then send a fixed quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
