Regrouting for homes and businesses in Coldharbour

If you’ve been scrubbing grout that won’t come clean, the discolouration has usually soaked into the grout. Replacing it is the lasting answer and you can pick a different colour while you are at it. If you have good tiles let down by tired grout and splashback grout that has darkened, we can put it right, whatever the surface.

London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Coldharbour, that is a good reason to put tired sealant and grout right early.

There’s a 12-month guarantee on every job, large or small.

Quotes for regrouting in Coldharbour

For a quick quote, just ask. The main things that affect it are:

  • How many rooms, windows or areas are involved
  • The size of the job
  • Any mould that needs treating
  • Access and height

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Helping us quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • If someone has resealed it before

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.

The process

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to a full day, depending on the area. In a London area like Coldharbour, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. First we agree what’s being done and flag any loose tiles.
  2. Grout is raked out without chipping the tiles.
  3. Dust is cleared from every joint.
  4. The new grout goes in, then the tile faces are cleaned.
  5. Internal corners and edges are resealed.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Move anything stored near the joints
  • Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods

Kitchen splashbacks

Grout behind the hob and sink works hard. We regroute and reseal the worktop joint.

Shower walls

Shower walls are the most common area we regrout. Cracked or missing grout here lets water behind the tiles.

Looking after it afterwards

So the new joints stay in good condition:

  • Run the extractor fan during and after a shower
  • Keep an eye on the silicone along the edges
  • Wipe water off the walls when you are done
  • Stick to mild products for cleaning grout

A squeegee or cloth over the tiles after use stops soap and water sitting on the grout. Ventilate the room well so the grout dries between uses.

Fixing grout early is a small job. Left, the same problem can let water through so it’s worth dealing with as soon as you spot it.

Coldharbour: your questions answered

Do you work for landlords with property near Mottingham station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.

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

Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

What guarantee comes with the work?

You get our 12-month guarantee on every job, and we’re fully insured.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. Our applicators cover Coldharbour, along with the rest of our area.

How do I get a quote for regrouting in Coldharbour?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Regrouting in Coldharbour: local notes

London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.

If you live in an older home near St Alban, timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Coldharbour can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like Mottingham Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What we cannot put right

We will always be straight with you, so here’s what sealant cannot fix:

  • A leaking shower valve or waste
  • Loose tiles, which need refixing first
  • Waterproofing that has failed below the tiling

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What we seal

  • Tiled floors
  • Bathroom floors
  • Kitchen splashbacks
  • Wet rooms
  • Bathroom wall tiles
  • Shower walls

Should I try it myself first?

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
