For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
How we handle commercial sealant in Little Portugal
Hotel bathrooms take hard daily use and constant cleaning, so sealant wears out faster than it would at home. Rooms are resealed in batches, keeping most rooms available, with a cure time for each room so housekeeping know when to release it. We’re often asked to deal with whole floors of tired en suites and sealant failing again soon after quick repairs, across retail & leisure sites, rental portfolios and student & care accommodation.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Little Portugal cannot close.
Big or small, it’s backed by our 12-month guarantee.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take as long as the scope needs, from one welfare room to a full building, and we tell you how long to leave it before we go. In Little Portugal, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Why act early in Little Portugal
Room by room, the work is quick: it takes a few hours for a single washroom, longer for a whole building. After that, each area needs its cure time before use, so the programme is planned around cure times. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Little Portugal.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

- Tired sealant in let properties

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the joints during routine room inspections
- Note the date each area was done
- Leave squeegees in busy showers
- Get split or lifting joints looked at early
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.
