- Leaks from pipes, valves or wastes (a plumber’s job)

Regrouting in St Nicholas, done properly
We check the tiles before any grout comes out. Loose or hollow tiles are pointed out first, since new grout can’t fix a problem underneath. With sound tiles, regrouting is a tidy, lasting improvement. If you have gaps where the shower grout has gone and good tiles let down by tired grout, we can help, on kitchen splashbacks, shower walls and wet rooms alike.
Homes around St Nicholas range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
There’s a 12-month guarantee on every job.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, 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.

Common questions in St Nicholas
I let a flat near Stevenage station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is it worth replacing old sealant in an older home in St Nicholas?
If it hasn’t been replaced for some years, it’s normally worth it. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in St Nicholas may already be on their second or third set.
How much does regrouting cost in St Nicholas?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
Could my grout be a different colour after regrouting?
Yes, regrouting is the time to do it. Mention the colour you have in mind when you call 0345 464 0079 or drop us an email.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Common problems we fix in St Nicholas
Hard water and soap leave a film on grout and stick to it. The grout beneath can stain and weaken, which is when replacing it makes sense.
People generally contact us when they notice something like this:
- Grout that makes sound tiles look old
- Kitchen splashback grout stained by grease
- Grout washed out of a shower
- Corners filled with grout instead of silicone
Rented homes near Stevenage station change hands often, and stained grout drags a rental down, and regrouting between lets puts that right.

St Nicholas homes and their sealant
Stevenage, which St Nicholas is part of, is one of England’s 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. Sealant laid over old sealant never bonds properly, so it all has to come out. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as All Saints Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as The Leys Primary and Nursery School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a shower enclosure, longer for a whole room in most cases. For a job in St Nicholas, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check the tiles for any that are hollow or loose.
- We rake out the grout evenly, protecting the tile edges.
- The joints are vacuumed clean.
- New grout is pressed into the joints and the tiles are cleaned.
- We finish with silicone in the moving joints.
