Regrouting for homes and businesses in Boxmoor
Regrouting suits shower walls, bathroom floors, kitchen splashbacks and wet rooms. Some jobs are a whole room, others just the shower. Whatever the size, the method stays the same. If you’re dealing with shower grout that has worn away and splashback grout that has darkened, we can put it right, on shower walls, bathroom wall tiles and bathroom floors alike.
Around Boxmoor, you will mostly find houses and bungalows, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
With regrouting, your tiles stay where they are. Retiling is a much bigger job: stripping, making good, new tiles and new grout, and often a few days without a shower. If the tiles are sound, regrouting is the simpler fix. Around Boxmoor, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What affects the quote in Boxmoor
We don’t publish a price list, because jobs vary so much. What we look at:
- Any mould that needs treating
- The size of the job
- Access and height
- How many areas need sealing
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
There’s no need for technical detail. Just tell us:
- The type of property
- The address or postcode of the job
- Photos by email, if that’s easy
- Whether it has been sealed before
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Give the walls a quick rinse after use
- Do not use strong acidic cleaners on grout
- Keep an eye on the silicone along the edges
- Clean grout with a mild bathroom cleaner
Clean the grout with a mild bathroom cleaner with a soft brush. Keep harsh bleach and acid limescale removers away from it because they wear grout away.
Once grout cracks, it tends to get worse. Water gets in behind and the tiles can start to loosen and early regrouting can avoid a much bigger job.
Do you need regrouting in Boxmoor?
Poor ventilation keeps grout damp, and damp grout is where mould grows. When black spots keep returning, the mould has normally got into the grout.
Any of these means the joints need attention:
- Grout stained black or orange that won’t clean
- Shower grout that has worn away
- A grout colour that no longer suits the room
- Grout in corners that has cracked
Rented homes near Hemel Hempstead station change hands often, and stained grout drags a rental down, and regrouting between lets puts that right.

Boxmoor: your questions answered
Do older homes in Boxmoor need their sealant replacing?
If it hasn’t been replaced for some years, it’s usually worth it. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in Boxmoor may already be on their second or third set.
Do you cover smaller places like Boxmoor?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Hertfordshire.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, including regrouting.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How the job changes by surface
Shower walls
Shower walls get wet every day, so grout there works hardest. It generally fails first.
Kitchen splashbacks
Splashback grout picks up grease and cooking stains. Once it’s stained, new grout is often the only fix.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Cracked or broken tiles
- Leaks from pipes, valves or wastes (a plumber’s job)
- Movement in a stud wall or floor
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a shower enclosure, longer for a whole room, depending on how much there is to do. A visit to Boxmoor is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking the tiles for any that are loose or hollow.
- Old grout is raked out to a consistent depth without chipping the tiles.
- Dust and debris are vacuumed out of every joint.
- We fill the joints with new grout, then clean the tiles.
- Corners and edges are resealed with flexible silicone, not grout.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Boxmoor homes and their sealant
Boxmoor is part of Hemel Hempstead, 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. Sealant laid over old sealant never bonds properly, so it all has to come out. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
In the older streets around Church of St John the Evangelist and Attached Church Hall, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Boxmoor Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
