How the job changes by surface
Baths
The long joint down the side of a bath is where most leaks start, particularly where there’s a shower over the bath. We finish it with a single, even bead of anti-fungal silicone, tooled so water can’t sit on it.
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. It’s resealed in white, clear or a colour to suit.
Bathroom resealing in Hatfield, 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, tooled smooth so water runs off instead of sitting in a ridge. We work on baths, basins & vanity units and sinks & splashbacks, and the jobs we see most are water getting behind the bath panel and gaps where the bath or tray has moved.
In a town like Hatfield, older streets sit alongside newer estates, so bathrooms range from long-standing suites to recent refits. Either way, the sealant and grout are generally the first things to fail.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Dry worktop joints after washing up
- Don’t let bottles sit on the bead
- Let new sealant cure fully before it gets wet
- Run the extractor fan during and after every shower
Give the silicone time to cure before it gets wet, which is normally around 24 hours. Once it’s cured, wiping it down after use keeps it looking new.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. A reseal in time can save the worktop.

What bathroom resealing looks like in Hatfield
Hatfield is one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant won’t stick to old, so the old layers have to come out first. There are hotels and other places to stay in and around Hatfield. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around Church of St Luke, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Bishop's Hatfield Girls' School, we reseal washrooms and kitchens in schools and businesses as well as homes. For landlords with property near Hatfield station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

When it isn’t the sealant
In fairness, some problems need a different trade:
- Movement from a bath with loose feet or no proper support
- Damage behind the tiles that needs a tiler
- Water getting in through the grout rather than the sealant

Other services in Hatfield
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes two to three hours for a typical bath, depending on how much old sealant there is. Parking in a town like Hatfield is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We look at every joint first and check for movement or leaks.
- 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.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

What happens if it’s left?
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. Black mould and gaps in sealant do not fix themselves, and in a busy household in Hatfield they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Hatfield questions
Do you work in hotels near Hatfield?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do older homes in Hatfield need their sealant replacing?
In most cases, yes, if it hasn’t been done for a while. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in Hatfield may already be on their second or third set.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Hatfield.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Should I try DIY first?
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.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you reseal around my kitchen sink and worktop?
Yes. Next to the sink we use a food-safe product where it’s needed.
