Questions from Sydenham Hill
Is parking a problem for a job in Sydenham Hill?
Parking in Sydenham Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for hotels and guest houses in Sydenham Hill?
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.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What does bathroom resealing cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What colours of sealant can you use?
You are not limited to white: clear, white and colours chosen to suit the room. We can help you pick when we quote.
Does the resealing come with a guarantee?
Yes, a one-year guarantee. Good ventilation and gentle cleaning help it last.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Bathroom resealing in Sydenham Hill, done properly
A shower joint gets soaked every day. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. Each gets a bead of anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. We work on baths, basins & vanity units and shower trays & enclosures, and people most often call us about leaks into the floor or ceiling below and water escaping at the shower enclosure.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Sydenham Hill are no different.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We protect the area and cut out all of the old sealant.
- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We tidy up and give you the cure time, normally around 24 hours.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Related advice
Signs you need bathroom resealing in Sydenham Hill
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out keep the silicone damp for hours, and mould that has grown into the silicone usually won’t clean off.
Most people get in touch after spotting something like this:
- Water getting behind the kitchen upstand
- Cracked, shrunken or lifting silicone
- Lumpy, uneven sealant from a DIY attempt
- Black spots spreading through the bead
If you let a flat or house near Sydenham Hill station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
Questions to ask before booking
- When the joint can take water or movement
- How hidden problems are handled
- Whether the sealant suits the joint
- Are they insured?
Landlord and commercial work in Sydenham Hill
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Looking after it afterwards
So the new joints stay in good condition:
- Squeegee the walls and tray after use
- Open a window or run the fan so the room dries
- Keep an eye on the corners, where splits start
- Keep bottles off the sealant line
Keep water off the new bead until it has cured, which is usually around 24 hours. Once it’s cured, wiping it down after use keeps it looking new.
Worktop joints fail quietly. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. A reseal in time can save the worktop.
