About our washroom sealing in Shirley
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 vanity units and basins, showers, trays and wet room floors and IPS panels and cubicles, and what we are called in for most is failed sealant behind washroom basins and washrooms that look worn because of the sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Shirley is the same: the right product in a properly prepared joint.
A place of Shirley’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

FAQs: Shirley
Is Shirley off your patch?
Not at all. Shirley is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like University of Southampton for the vacation?
Yes. Education sites typically 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.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Hollow tiles or loose panels behind the joint
- Water from plumbing, not from a joint
- Water escaping beneath the floor rather than through a joint
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.
Surfaces we seal
- Urinals and WCs
- Vanity units and basins
- Kitchens and tea points
- Showers, trays and wet room floors
- IPS panels and cubicles
- Accessible toilets and changing rooms
When to call us in Shirley
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.
Look out for the following:
- Mould spotting along silicone joints
- Sealant lifting along a tray edge
- A new bead over an old one coming away
- Panel joints letting water behind
For a hotel such as Elizabeth House Hotel, 1.3 miles to the east of Shirley, resealing en suites a few rooms at a time keeps the rest available.
What to look for in a quote

Keeping Shirley washrooms open while we work
The sea is no more than about 1 mile from Shirley, and seaside hospitality usually has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready. The area within 2 miles of Shirley holds a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Halls of residence and teaching buildings at universities such as University of Southampton (1.5 miles east of Shirley) are easiest to reseal during vacations. At a college such as Richard Taunton Sixth Form College, which lies north-east of Shirley, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

Leave it or put it right?
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. For buildings in places like Shirley, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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.
