About our remedial sealant in Park Royal
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. We work on leaking tray & enclosure joints, expansion joints and botched or over-sealed joints, and people most often call us about mould trapped under a layer of silicone and kitchen joints letting water behind the worktop.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Park Royal are no different.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

What else we do in Park Royal
Park Royal homes and their sealant
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. Park Royal has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
If you live in an older home near St Gabriel's Church, walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as West Twyford Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Harlesden station, a joint that keeps failing is best fixed properly while the property is empty.
Park Royal is about 1 mile south-west of Harlesden, in Greater London. From the centre of Park Royal to the outskirts, remedial sealant is available for homes and businesses alike. 764 places in Greater London are on our list, large and small. For nearby work, see our London page.

The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. In Park Royal, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.

Related advice
Park Royal: your questions answered
Is parking a problem for a job in Park Royal?
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.
I let a flat near Harlesden station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
How long will it take to strip and reseal the joint?
Allow a few hours, depending on how many layers have to come out. You’ll know the timing when we quote.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
How do I get a quote for remedial sealant in Park Royal?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Why it’s worth doing now in Park Royal
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Park Royal, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why Park Royal customers choose us
- White, clear, grey or coloured to suit, where the product allows
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants
- Over 20 years’ experience
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
Landlord and commercial work in Park Royal
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How we quote for remedial sealant
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- Whether the work is at height
- The old material and how stubborn it is
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
