About our commercial sealant in Stanmore
Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. We work on rental portfolios, retail & leisure sites and office washrooms & kitchens, and people most often call us about silicone laid over old silicone by a previous contractor and failed floor-level joints in accessible wet rooms.
For a pub, café, guest house or shop in or near Stanmore, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Why it’s worth doing now in Stanmore
Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. One proper reseal beats several quick ones. Homes in smaller places like Stanmore can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a morning for a small washroom, and a planned programme for bigger sites, depending on how much there is to do. A visit to Stanmore is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Before we arrive
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Stanmore: your questions answered
Do you work for landlords with property near Winchester station?

Do you work in hotels near Stanmore?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

What does commercial sealant cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What we are called out for in Stanmore
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. A tray that isn’t fully supported soon tears its seal.
Signs it’s time to call us include:
- Black, stained silicone in guest bathrooms
- Failed joints in office kitchens and tea points
- Leaks from showers into rooms or ceilings below
- Split sealant where wet room floors meet walls
Community buildings like Saint Luke are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Use mild cleaners on sealant, not bleach or abrasives
- Add sealant to your planned maintenance checks
- Report broken fans quickly
- Plan resealing around quiet periods
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
Workplaces and buildings in Stanmore
There are hotels and other places to stay in and around Stanmore. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For landlords with property near Winchester station, several rental properties can be resealed on one programme. For site and facilities teams at buildings such as Stanmore Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
