Commercial sealant in Lisson Grove
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can go on one quote to keep things simple. Typical jobs include mouldy bathrooms flagged at a tenancy check and worktop sealant that has shrunk and stained, across rental portfolios, student & care accommodation and office washrooms & kitchens.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Lisson Grove, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
All of our work is guaranteed for twelve months.

Why it’s worth doing now in Lisson Grove
Room by room, the work is quick: the job takes a morning for a small washroom, and a planned programme for bigger sites. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

How the job changes by surface
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone, accessible showers included.
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so joints are sealed with anti-fungal sanitary silicone.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a single washroom, longer for a whole building. In Lisson Grove, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Related advice
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Your questions about commercial sealant in Lisson Grove
Can parking be tricky for a visit in Lisson Grove?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you take on hotel work around Lisson Grove?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Can you reseal bathrooms across several rental properties?
Yes. Between tenancies is a good time to reseal bathrooms and kitchens, and we can quote for several addresses at once.
How do I get a quote for commercial sealant in Lisson Grove?
Size, access and the old material all affect the cost. Ask us for a quote.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
What affects the cost of commercial sealant
For a quick quote, just ask. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The product the joint needs
- Whether there’s mould to deal with
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.
Helping us quote
To make quoting easier, let us know:
- Where the property is
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and send you a clear quote.
Looking after it afterwards
Looking after new joints is easy:
- Ask cleaners to go gently on the silicone
- Book larger programmes for quieter times of year
- Note the date each area was done
- Keep extractor fans working and serviced
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Certifying fire stopping or building compliance
- Tiles coming off the wall
- Damaged sanitaryware that needs replacing
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Workplaces and buildings in Lisson Grove
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. There are hotels and other places to stay in and around Lisson Grove. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you look after a building such as Gateway Academy, washroom and kitchen sealant can be programmed around term times or opening hours. If you look after a church, hall or community building such as St Paul's Community Church, halls and community kitchens see heavy use, and their sealant shows it. As a London address, Lisson Grove can be tricky for parking: let us know about parking bays, permits or a driveway.
