Bathroom resealing across AL7: what to expect
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. It also seals the gaps that let water behind the bath. We work on sinks & splashbacks, basins & vanity units and wet rooms, and common reasons people get in touch are water getting behind the bath panel and sealant that has split, shrunk or peeled away.
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take around two hours for one bath or shower, longer for a whole bathroom.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, normally around 24 hours.

Where we work in AL7
Our bathroom resealing work across AL7 covers homes, rentals and businesses, in Welwyn Garden City, Haldens and Hatfield Hyde and well beyond. The method is the same everywhere: old material cut out, joints cleaned and dried, and a fresh finish laid.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. For any job in AL7, joints are cleaned back properly before anything new goes in.
Welwyn Garden City: Schools such as Peartree Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church Of Saint Francis Of Assisi include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What affects the quote in AL7
The price is agreed before any work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- The amount of work
- Which sealant suits the joint
- Whether the work is at height
Instead of a standard rate, 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.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How the job changes by surface
Sinks & splashbacks
Next to the sink, the sealant has to cope with constant water, and a food-safe product where it’s needed. The joint is laid neatly so it’s easy to wipe.
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. The new bead is colour-matched where it shows, so the line does not stand out.
Common problems we fix in AL7
Baths and trays move. Acrylic in particular gives slightly under the weight of water and a person, while a poorly supported tray can shift underfoot. Over time the joint tears or pulls away from the tile.
The most common problems we see are:
- Cracked, shrunken or lifting silicone
- Failed sealant on the screen profile
- Gaps where the bath or tray has moved
- Black mould in the silicone that won’t clean off
AL7: your questions answered
Is white the only colour available?
White and clear are the most common choices, and other colours are available to suit tiles, trays and worktops. Let us know your preference when you ask for a quote.
Do you guarantee your resealing?
Yes, for 12 months. Good ventilation and gentle cleaning help it last.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Keep water off it for around 24 hours, or follow the cure time we give you.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Is it OK to put new sealant on top of the old bead?
No. It’s a common reason for reseals failing. The old joint is stripped, cleaned and resealed from scratch.
