About our commercial sealant in Stroud Green
Staff facilities cannot be out of action for long. Early starts and out-of-hours work can be arranged so the working day is disturbed as little as possible. Each area is handed back with its cure time. We work on rental portfolios, hotel bathrooms and student & care accommodation, and common reasons people get in touch are mouldy washroom sealant that staff and guests notice and leaking joints in shower rooms and changing areas.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Stroud Green, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
A 12-month guarantee comes as standard.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask cleaners to go gently on the silicone
- Act on lifting sealant before it leaks
- Check the joints during routine room inspections
- Tell cleaning staff when each room can be used
We give a cure time for every area we finish, which is generally around 24 hours. Pass it on to housekeeping or cleaners so the new sealant isn’t wetted or scrubbed too soon.
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.
What commercial sealant looks like in Stroud Green
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
As a London address, Stroud Green can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near Harringay station, several rental properties can be resealed on one programme.

How we quote for commercial sealant
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Roughly how big the job is
- The problem you’ve noticed
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed 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.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured for the work.

What else we do in Stroud Green
Common problems we fix in Stroud Green
Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
People generally contact us after spotting something like this:
- Washrooms that need sorting before an inspection
- Whole floors of tired en suites
- Mouldy bathrooms flagged at a tenancy check
- Worktop sealant that has shrunk and stained
For site and facilities teams at buildings such as St Aidan's Voluntary Controlled Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

FAQs for Stroud Green
I let a flat near Harringay station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can parking be tricky for a visit in Stroud Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work in Stroud Green?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Stroud Green.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How soon can a room be used after resealing?
Usually after around 24 hours. Each room is handed back with the cure time for the product used.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Honest limits
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Assessing what fire stopping a building needs
- Faulty shower valves and leaking traps
- Cracked trays or baths rather than failed joints
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes as long as the scope needs, from one welfare room to a full building. For a job in Stroud Green, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
