About our regrouting in Bloomsbury

A bathroom with good tiles can still look worn if the grout has gone. Regrouting replaces the grout and keeps the tiles you have, so nothing is ripped out. We work on bathroom floors, shower walls and wet rooms, and the jobs we see most are floor grout that has worn and darkened and grout that stays dark however much it’s cleaned.

London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Bloomsbury more than a cosmetic job.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Quotes for regrouting in Bloomsbury

Jobs vary more than people expect. What affects the quote:

  • Any working-time requirements on site
  • The type of sealant required
  • Whether the work is at height
  • How many rooms, windows or areas are involved

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

When you call or email, it’s useful to know:

  • The rough size of the job
  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • Pictures of the joints, sent by email

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

How it works

You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a shower enclosure, longer for a whole room in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. We start by checking the tiles for any that are loose or hollow.
  2. Old grout is raked out to a consistent depth without chipping the tiles.
  3. Dust and debris are vacuumed out of every joint.
  4. New grout is worked into the joints and cleaned off the tile faces.
  5. We reseal the internal corners and edges with silicone.

Before we arrive

  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in

How to get a quote

Bloomsbury homes and their sealant

There are hotels and other places to stay in and around Bloomsbury. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London’s water is hard, which leaves limescale on sealant, grout and taps.

For landlords with property near London Euston station, a regrout while the flat is empty is quicker than working around a tenant. Bloomsbury is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Bloomsbury questions

Could a tired shower seal in my Bloomsbury flat affect the neighbours below?

Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.

Do you work for hotels and guest houses in Bloomsbury?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

How long does regrouting take?

A typical job takes a few hours, or longer for a fully tiled room. Your quote will say how long we expect yours to take.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.

Is it OK to seal over old sealant?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Can you change the grout colour?

Yes. With the old grout removed, the new colour fills the whole joint, not just the surface.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Common problems we fix in Bloomsbury

Grout used in corners or along the bath cracks as the bath or tray moves. They need flexible sealant, and when they aren’t, water gets in.

It’s worth asking for a quote if you see:

  • Grout that is cracking and breaking up
  • Old grout in a dated colour
  • Grout stained black or orange that will not clean
  • Splashback grout that has darkened

Homes close to St George the Martyr Holborn include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Before you book anyone

  • How long to leave it before use
  • How the colour is chosen
  • What insurance they hold
  • Whether they seal over old material or remove it

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Use a squeegee on the tiles after showering
  • Skip wire brushes and scourers
  • Have loose tiles looked at early
  • Use gentle cleaners on grout

We will tell you when the area can be used again. Please follow it, and go gently on the grout at first.

Cracked grout does not stay cracked for long. Water gets behind the tiles, and they can begin to come away and early regrouting can avoid a much bigger job.

Why it’s worth doing now in Bloomsbury

If tiles are loose, regrouting alone isn’t the answer. We point that out first so you know what’s involved. On sound tiles, regrouting avoids the upheaval of a retile. In a flat in Bloomsbury, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

What the job involves on each surface

Kitchen splashbacks

A splashback can be regrouted without touching the worktop. The joint along the worktop is resealed with silicone.

Corners and edges

The joint between tiles and a bath, tray or worktop gets silicone. Grout there would crack.
