What affects the cost of commercial sealant
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- The size of the job
- The product the joint needs
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, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- The type of property
- If someone has resealed it before
- The address or postcode of the job
- Photos by email, if that’s easy
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear price.
How we handle commercial sealant in Hampstead
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. If you’re dealing with tired sealant ahead of a health and safety audit and failed floor-level joints in accessible wet rooms, we can help.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, 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 Hampstead cannot close.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Questions from Hampstead
Do you take on hotel work around Hampstead?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I let a flat near Finchley Road & Frognal station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Can you supply method statements and risk assessments?
Let us know your site’s requirements. We will confirm what we can provide alongside the quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is out-of-hours working possible?
That can be arranged for many jobs. The hours are agreed before work starts.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the job changes by surface
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. Anti-fungal sanitary silicone is used throughout, accessible showers included.
Hotel bathrooms
We can plan around check-out and check-in times.
Leave it or put it right?
Sealant is easy to forget until an audit or inspection is due. Planning the work ahead means rooms are finished and cured in time. In a flat in Hampstead, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
Why us?
- Every job guaranteed for a year
- Neat joints and a tidy finish
- Approved under the ARBOMaster scheme
- Experience in homes, commercial sites and hotels
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the number of rooms, including the tidy-up. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Hampstead. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Hampstead
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. If a tray flexes, the sealant around it splits.
The most common problems we see are:
- Leaking joints in shower rooms and changing areas
- Large numbers of bathrooms needing the same work
- Split sealant around staff kitchen worktops and sinks
- Joints that need doing before an inspection or audit
If you look after a church, hall or community building such as St John-at-Hampstead church, halls and community kitchens see heavy use, and their sealant shows it.

Workplaces and buildings in Hampstead
There are hotels and other places to stay in and around Hampstead. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Finchley Road & Frognal station, sealant work can be quoted for a single flat or a whole portfolio. If you look after a building such as Fitzjohn's Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Act on lifting sealant before it leaks
- Book larger programmes for quieter times of year
- Leave squeegees in busy showers
- Check extract fans are actually running
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
