How the job changes by surface
Changing rooms and gyms
Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. We use anti-mould sanitary silicone throughout.
Kitchens and tea points
Kitchen work can be phased around service. Tell us your site hours and access windows and we will plan around them.
How we handle washroom sealing in Southsea
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on accessible toilets and changing rooms, kitchens and tea points and vanity units and basins, and what we’re called in for most is failed joints along IPS and cubicle panels and washrooms that look worn because of the sealant. Most enquiries from Southsea start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Pubs, restaurants and cafés in a town like Southsea have kitchens and customer toilets that need smooth, sealed joints. Environmental health officers look at cleanability, and a sound sanitary or hygienic sealant is part of that.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Commercial washrooms in Southsea
Southsea lies within about 1 mile of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, so we plan the work for quieter weeks where possible. At about 65 miles from central London, Southsea is within reach of the capital, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.
En suites at hotels like G Boutique Hotel (less than half a mile south of Southsea) are cleaned daily, which wears silicone over time. At a retail site such as The Bridge Shopping Centre, 1 mile north of Southsea, public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases. Toilets at colleges like Portsmouth College (1.9 miles north-east of Southsea) take heavy use from students and staff alike.
Southsea is about 2 miles south of Portsmouth, in Portsmouth. Southsea sits inside our coverage and the rest of Portsmouth, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Portsmouth, 19 places are covered, including Southsea.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If you have more than one building in Southsea, they can often be done on the same visit. Give us your access times and we will fit the work in.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Hollow tiles or loose panels behind the joint
- Failed tanking beneath a wet-room floor or behind tiles
- A dripping waste or valve behind a panel
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Vanity units and basins
- Urinals and WCs
- Accessible toilets and changing rooms
- Kitchens and tea points
- IPS panels and cubicles
- Showers, trays and wet room floors
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- The total length or number of joints
- Backing rod, priming and other preparation
- Distance, for remote addresses
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Access details, including height
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call the office on 01277 525 020 or email drawings and photos.
Leave it or put it right?
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Questions we are asked in Southsea
Will you work in a care home in Southsea without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Could you schedule work at a campus like University of Portsmouth for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Do you guarantee washroom sealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
