How the job changes by surface
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Cracked grout in a corner can be cut out and replaced with silicone.
Bathroom resealing for homes and businesses in South Harrow
A shower joint gets soaked every day. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. They’re resealed with anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. We work on basins & vanity units, sinks & splashbacks and wet rooms, and people most often call us about black mould in the silicone that won’t clean off and cracked, shrunken or lifting silicone.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Bathrooms and kitchens in South Harrow
London has hard water, which leaves limescale on sealant, grout and taps. 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.
If you look after a building such as The Welldon Park Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Northolt Park station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. In the older streets around Parish Church of St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.

How we quote for bathroom resealing
There’s no set price list. What we look at:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
Before you ask for a quote, have a think about:
- The type of property
- The address or postcode of the job
- Photos by email, if that is easy
- Roughly how big the job is
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.
What happens on the day
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take half a day or less for one room, longer when the kitchen is included. In a London area like South Harrow, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We tidy up and give you the cure time, generally around 24 hours.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Let us know about parking restrictions

Other services in South Harrow
South Harrow: your questions answered
Do you work for landlords with property near Northolt Park station?
Yes, we work for letting agents and landlords. You can phone 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 work in hotels near South Harrow?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you cover South Harrow?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes South Harrow.
Where do you work from?
We work from Crawley. Our applicators cover South Harrow.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
How long does the new silicone need before I use the shower?
Silicone is touch-dry quite quickly, but it takes longer to cure. Keep water off it for around 24 hours, or as long as we advise for that product.
Why act early in South Harrow
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Skip those steps and even the best silicone fails early. In a flat in South Harrow, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

Aftercare tips
After the cure time, these simple habits help:
- Use gentle cleaners on the silicone
- Never pick at the silicone with a blade
- Let new sealant cure fully before it gets wet
- Dry worktop joints after washing up
Check the sealant now and then. Small splits and lifting ends are easy to catch early, so if something doesn’t look right, just ring 0345 464 0079 or send us an email.
There’s no need to wait for a full refurbishment. Like paintwork, sealant needs renewing from time to time, and replacing it when it fails protects the rest of the room.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out 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.
