Regrouting in Underhill, done properly
Our applicators rake out the old grout to an even depth, taking care not to chip the tile edges. After vacuuming, new grout goes in and the tiles are wiped clean, with silicone renewed in the corners. If you have discoloured grout on otherwise sound tiles and grout that stays dark however much it’s cleaned, we can put it right.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
Your job is guaranteed for a year, as with all our work.

How to look after the new joints
After the cure time, these simple habits help:
- Get any tile that moves checked promptly
- Clean with a soft brush, not anything metal
- Stick to mild products for cleaning grout
- Wipe or squeegee the shower walls
Use a gentle cleaner on the grout and a soft brush. Keep harsh bleach and acid limescale removers away from it, as they can break grout down.
If grout in the shower is washing out, act soon. Each shower drives water into the open joints, and that water can reach the wall or the floor below.

What else we do in Underhill
When something else is needed
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Failed tanking or waterproofing under the tiles
- Tiles that are loose or hollow behind
- Leaks from pipes, valves or wastes (a plumber’s job)
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Common problems we fix in Underhill
Hard water and soap leave a film on grout and stick to it. The grout beneath can stain and weaken, and at that point, new grout is the better answer.
Keep an eye out for any of the following:
- Stained grout that cleaning won’t shift
- Old grout in a dated colour
- Dirty, worn grout on a tiled floor
- Good tiles let down by tired grout
Letting a property close to New Barnet station? Then a regrout while the flat is empty is quicker than working around a tenant.

Questions from Underhill
Is parking an issue for regrouting in Underhill?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I live in a flat in Underhill. Can a failed seal leak into the flat below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
What does regrouting cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What goes in the corners, grout or silicone?
Flexible sealant. Grout is for the joints between tiles and moving joints need sealant.
Should I try it myself first?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What regrouting looks like in Underhill
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Underhill is in London, so parking needs planning: let us know about parking bays, permits or a driveway. In the older streets around St John the Baptist Church, walls and floors in older homes can move, and sealant and grout show it first.

What’s near Underhill
We work in homes and buildings around Susi Earnshaw Theatre School, Highlands Gardens and The Red Lion pub and the streets around them. Underhill’s nearest station is New Barnet station, roughly 1 mile east of the centre. Nearby you will also find Francis Skaryna Belarusian Library and Museum (2.2 miles south) and Barnet General Hospital (0.9 miles west). The countryside around Underhill includes Greenhill Gardens and Darland's Lake.
Why it’s worth doing now in Underhill
Bleach can lighten stained grout for a while, but mould that has got into grout normally comes back. Replacing the grout and resealing the edges is a lasting fix. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Underhill.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Surface by surface
Corners and edges
The joint between tiles and a bath, tray or worktop gets silicone. Grout there would crack.
Bathroom wall tiles
Walls outside the shower get less water but still stain and crack. New grout freshens them up.
