About our bathroom resealing in Colney Heath
A fresh bead of silicone changes how a bathroom looks more than most people expect. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. We work on kitchen worktops & upstands, sinks & splashbacks and shower trays & enclosures, and the jobs we see most are damp behind the bath or under the tray and water escaping at the shower enclosure.
Around Colney Heath, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Common problems we fix in Colney Heath
Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, leaving a thin gap where water and food collect. Heat from the hob and strong sprays speed it along.
Most people get in touch after spotting something like this:
- A joint torn by a bath that flexes
- Damp behind the bath or under the tray
- Two layers of silicone, both failing
- Cracked, shrunken or lifting silicone
For site and facilities teams at buildings such as Colney Heath Junior Mixed Infant and Nursery School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- Is the old sealant removed completely?
- When the joint can take water or movement
- How the colour is chosen
- Whether they’re fully insured
What happens on the day
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Somewhere as small as Colney Heath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by protecting the area and stripping out the old bead.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We tidy up and give you the cure time, usually around 24 hours.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Your questions about bathroom resealing in Colney Heath
Do you work for hotels and guest houses in Colney Heath?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you work for landlords with property near Welham Green station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
When it is not the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Water getting in through the grout rather than the sealant
- Damage behind the tiles that needs a tiler
- A tray that rocks until it’s re-bedded
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Clean with a mild bathroom cleaner and a soft cloth
- Don’t let bottles sit on the bead
- Do not leave water standing on kitchen joints
- Keep scourers and sharp tools away from the bead
Check the sealant now and then. A small split or a corner lifting is easy to spot, so if something does not look right, just phone 0345 464 0079 or send us an email.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, and the board underneath can swell. Resealing before that happens protects the worktop.
Surface by surface
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so a neat, continuous bead matters.
Sinks & splashbacks
Splashbacks in glass, tile or acrylic meet the worktop in a long joint. We renew it in clear, white or a matched colour.
Colney Heath homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Colney Heath is part of Hatfield, 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. New sealant will not stick to old, so the old layers have to come out first.
If you live in an older home near Church of St Mark, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For landlords with property near Welham Green station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
