Surface by surface
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, and we’ll tell you if we find it.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Remedial sealant in Hatfield
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. We are often asked to deal with dark patches showing through the sealant and worktop sealant that has shrunk and split, on leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant.
Hatfield mixes older houses with estates built more recently, so bathrooms range from long-standing suites to recent refits. Whatever their age, sealant and grout tend to go before anything else.
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.

What we do, step by step
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. 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.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Honest limits
In fairness, some problems need a different trade:

Remedial sealant in Hatfield: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Hatfield is one of the post-war new towns. Many homes date from the post-war decades, so bathrooms and kitchens may be on their second or third set of sealant. Sealant laid over old sealant never bonds properly, so it all has to come out.
If you live in an older home near Church of St Luke, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Bishop's Hatfield Girls' School, we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Hatfield station? Then a joint that keeps failing is best fixed properly while the property is empty.

Questions from Hatfield
Can you help a landlord with a rental near Hatfield station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Should the sealant in an older Hatfield home be renewed?
Usually, yes, if it’s cracked, shrunk, mouldy or coming away. The key is cutting all the old sealant out, as new sealant will not bond to it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long does remedial resealing take?
It takes a few hours, depending on how many layers have to come out. We’ll give you a timescale when we quote.
Do you cover Hatfield?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Hatfield included.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
What if resealing will not fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What affects the quote in Hatfield
The quote reflects the job in front of us. We look at:
- The type of sealant required
- Access and height
- The old material and how stubborn it is
- Any working-time requirements on site
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.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- The address or postcode of the job
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
What happens if it’s left?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. Around Hatfield, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the 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.
