Washroom sealing for Marchwood sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
To get the most from the new sealant:
- Clean sealant with gentle products and a soft cloth
- Don’t leave an open joint at a basin or tray
- Don’t leave trays and floors sitting wet
- Keep washrooms out of use until we say the sealant has cured
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well so failed joints are worth acting on quickly.
About our washroom sealing in Marchwood
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. If you are dealing with washrooms that look worn because of the sealant and a new bead over an old one coming away, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Marchwood it comes down to the same thing: the right product in a properly prepared joint.
A place of Marchwood’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Commercial washrooms in Marchwood
Marchwood sits close to the coast, within about 1 mile, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, so we plan the work for quieter weeks where possible. A 2-mile radius around Marchwood takes in several hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
On an industrial estate such as Marchwood Industrial Park, 0.7 miles to the north-east of Marchwood, staff toilets, showers and canteens are where sanitary sealant takes the most wear. At a university such as Southampton Solent University, which lies north-east of Marchwood, summer is the usual window for resealing residence bathrooms.
Marchwood is about 3 miles south-east of Totton, in Hampshire. Our applicators travel to Marchwood for work on washrooms and wet areas, handled exactly as we handle every other area. Marchwood is one of 723 places we cover in Hampshire.
We take on washrooms and wet areas across the SO40 postcode area. Among the streets we cover are Cranberry Close, Melick Close and The Rowans, and sites on any of them can send details for a fixed quote. Being close to the A326, Marchwood is easy to get to with materials and equipment. If your building is just outside Marchwood, we cover Dibden (2 miles south-east), Dibden Purlieu (3 miles south-east), Hythe (3 miles south-east), Beaulieu (5 miles south) and Furzey Lodge (5 miles south). Bigger towns within reach include Winchester (13 miles north-east), Gosport (14 miles south-east), Eastleigh (7 miles north-east), Fareham (11 miles east), Totton (3 miles north-west) and Chandler's Ford (7 miles north-east).
Near you in Marchwood
We work on buildings around White Horse pub and Hounsdown School. The nearest railway station is Millbrook (Hants) station, about 1.6 miles north-east of the centre. Well-known places in the area include Netley Castle (4.1 miles east) and Westquay (2.1 miles east). For a walk, there’s Testwood Lakes.
Common problems we fix in Marchwood
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.
It’s worth sending us details if you spot any of the following:
- Gaps where vanity tops meet the wall
- Urinal joints that look unhygienic
- A new bead over an old one coming away
- Kitchen worktop joints that can’t be kept clean
Healthcare washrooms on sites such as Priory Hospital (to the south of Marchwood) are resealed area by area, under the site’s own infection-control rules.
Questions to ask before you book
- What site paperwork they can supply
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- Proof of insurance
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites around Marchwood. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Why it’s worth doing now in Marchwood
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Small buildings around Marchwood suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Your questions answered
Could you schedule work at a campus like Southampton Solent University for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Marchwood too small for you to travel to?
No. Places such as Marchwood are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Will you quote for a small job?
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.
Will cleaning remove black mould from sealant?
Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.
Is it OK to put new silicone on top of the old?
The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
