Regrouting in New Denham
We check the tiles before any grout comes out. If any tiles are loose or sound hollow, we tell you, because regrouting won’t fix what’s behind them. Where the tiles are sound, regrouting gives the area a new lease of life. We are often asked to deal with discoloured grout on otherwise sound tiles and splashback grout that has darkened, on wet rooms, shower walls and bathroom floors.
Somewhere as small as New Denham, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All our work comes with our one-year guarantee, wherever you are in Buckinghamshire.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When to call us in New Denham
Hard water and soap leave a film on grout and stick to it. In time the grout under it darkens and breaks down, and at that point, new grout is the better answer.
Common reasons people contact us are:
- Grout that is cracking and breaking up
- Shower grout that has worn away
- Dirty, worn grout on a tiled floor
- Corners filled with grout instead of silicone
For site and facilities teams at buildings such as Hermitage Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before you book anyone

- When the joint can take water or movement
- Is the old sealant removed completely?

What regrouting looks like in New Denham
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.
For an older house near a landmark such as St Francis, older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Denham station, stained grout drags a rental down, and regrouting between lets puts that right.

Why deal with it now?
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. When the tiles are fine, it’s the sensible first step. Where a wall is exposed, as many are in small places like New Denham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

New Denham: your questions answered
Is New Denham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Denham station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is it possible to regrout only the shower area?
Yes. Many jobs are just the shower walls, or just the joints that have failed.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
When can I use the shower again?
You’ll get a clear time from us before we go. The grout and sealant both need to cure before they get wet.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover New Denham, along with the rest of our area.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you guarantee regrouting?
All our work carries a 12-month guarantee.

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in.

For outside work, also let us know about exposed walls and any outbuildings involved.

- The old grout comes out to a consistent depth, without damaging the tiles.
- Dust and debris are vacuumed out of every joint.
