Regrouting in Harwell
Most regrouting jobs include resealing too. Grout belongs between tiles, but corners and edges move, so they’re sealed with silicone rather than grout. Doing both at once leaves the whole area sound. We work on kitchen splashbacks, bathroom floors and shower walls, and the jobs we see most are grout in a colour the owner wants to change and grout in corners that has cracked.
In and around Harwell, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
There’s a 12-month guarantee on every job, whatever its size.

What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a shower enclosure, longer for a whole room. In a smaller place like Harwell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check the tiles are sound and flag any that are loose or hollow.
- The old grout comes out to a consistent depth, without damaging the tiles.
- The joints are vacuumed and cleaned.
- New grout is worked into the joints and cleaned off the tile faces.
- Corners and edges are resealed with flexible silicone, not grout.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Wet rooms
Regrouting a wet room helps keep water on the surface of the tiles. It cannot fix waterproofing below the tiles.
Corners and edges
The joint between tiles and a bath, tray or worktop gets silicone. Grout there would crack.

Regrouting around Harwell
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Harwell. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For an older house near a landmark such as Church of St Matthew, older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Didcot Parkway station? Then clean grout and fresh sealant between tenancies make a bathroom look cared for again.

Quotes for regrouting in Harwell
The price is agreed before any work begins. It takes into account:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the property is
- The problem you’ve noticed
- The type of property
- Whether it has been sealed before
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Wipe water off the walls when you’re done
- Keep harsh bleach and acid cleaners off the grout
- Check the corner silicone every few months
- Have loose tiles looked at early
If a tile starts to feel loose, get it looked at early. A loose tile cracks the grout around it and open a path for water.
Tiles can come away if failed grout is left. By then, new grout alone is not enough so early action pays.
Common problems we fix in Harwell
Strong cleaning products and hard scrubbing slowly erode grout. Some bleaches and acid descalers break grout down over time, until the joints are rough and low.
Signs it’s time to call us include:
- Stained grout that cleaning won’t shift
- Discoloured grout on otherwise sound tiles
- A grout colour that no longer suits the room
- Grout in corners that has cracked
Schools such as Harwell Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- Are they insured?
- When the joint can take water or movement
- What happens if the job turns out different
- Whether they seal over old material or remove it
