Why it’s worth doing now in Newnham
If tiles are loose, regrouting alone is not the answer. We’ll tell you before we start, so you can decide what to do. On sound tiles, regrouting avoids the upheaval of a retile. Older cottages and farmhouses around Newnham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Regrouting in Newnham, done properly
When grout stays dark however much you clean it, the stain is often in the grout itself. Replacing it is the lasting answer, and it’s a chance to change the colour too. Common call-outs are for good tiles let down by tired grout and grout stained black or orange that won’t clean, on shower walls, wet rooms and bathroom wall tiles.
Somewhere as small as Newnham, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in Newnham
What we are called out for in Newnham
Hard water and soap leave a film on grout that’s hard to shift. In time the grout under it darkens and breaks down, which is when replacing it makes sense.
Any of these means the joints need attention:
- Stained grout that cleaning won’t shift
- Kitchen splashback grout stained by grease
- Crumbling grout between the tiles
- Dirty, worn grout on a tiled floor
If you live in an older home near Church of St Vincent, walls and floors in older homes can move, and sealant and grout show it first.

Surface by surface
Bathroom floors
Floor grout takes foot traffic as well as water. It gets worn and dirty.
Wet rooms
Both the grout and the silicone in a wet room matter. We renew both.
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on the area. Somewhere as small as Newnham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree what’s being done and flag any loose tiles.
- Grout is raked out without chipping the tiles.
- Dust is cleared from every joint.
- The new grout goes in, then the tile faces are cleaned.
- We renew the silicone at the corners and edges.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Advice
DIY versus a professional finish
If you do try it yourself, take your time over the 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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Regrouting around Newnham
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.
For landlords with property near Baldock station, stained grout drags a rental down, and regrouting between lets puts that right. If you look after a building such as The Knights Templar School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Your questions about regrouting in Newnham
Is Newnham in your area for regrouting?
Yes. Our work covers London and the South East, and Newnham is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Do you cover smaller places like Newnham?
Yes, Newnham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What goes in the corners, grout or silicone?
Internal corners and edges are sealed with flexible silicone. Grout in those joints cracks as the building moves.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Is the work guaranteed?
There’s a 12-month guarantee on every job, including regrouting.
Can you regrout if a few tiles are loose?
If tiles are loose, something behind them has generally failed. Grout on its own will not fix that, and we’ll tell you before work begins.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
