How we handle washroom sealing in Portswood
Whether it’s a single toilet block in Portswood or a programme across several buildings, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photographs and a count of fittings are enough for a quick quote and a site visit is an option. We work on urinals and WCs, accessible toilets and changing rooms and IPS panels and cubicles, and what we are called in for most is complaints from staff, guests or users about tired washrooms and black mould inside silicone joints that cleaning can’t shift. Looking for mastic applicators who cover Portswood? We’ve been sealing commercial buildings since 2005.
In a smaller place such as Portswood, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Surface by surface
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.
Showers and trays
Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.
How the quote is worked out
These are the things that shape the price:
- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
- Access and working height
- Distance, for remote addresses
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.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
- Your programme or deadline
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Our process

- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.

Common questions from Portswood clients
Is a smaller place like Portswood outside your area?
Not at all. Portswood is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Royal South Hants Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What will the job cost?
Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or send details through our quote form with a description of the work.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, 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.
Signs you need washroom sealing in Portswood
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Typical triggers for a call:
- Washrooms that look worn because of the sealant
- Failed sealant in a tea point or staff kitchen
- Open joints along basins and vanity units
- Shower tray joints that have opened up
For buildings on a site such as Itchen Business Park (0.5 miles north-east of Portswood), washrooms and tea points can be resealed in phases through the working week.
What your quote should include
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
