Regrouting for homes and businesses in Sidcup
We work across Sidcup, regrouting bathrooms, showers and kitchens. Out comes the old grout, the joints are cleaned and new grout goes in, finished with new silicone at the edges. If you have crumbling grout between the tiles and stained grout that cleaning won’t shift, we can put it right, whatever the surface.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Surface by surface
Bathroom wall tiles
Whole bathroom walls can be regrouted in one visit or more, depending on size. You can change the colour at the same time.
Bathroom floors
If floor grout keeps cracking, the floor may be moving. We check the tiles before regrouting.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
FAQs for Sidcup
Can you help a landlord with a rental near Sidcup station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Can worn sealant in a flat in Sidcup cause a leak downstairs?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Are you insured?
Yes. Mr Mastic is fully insured.
Do you cover Sidcup?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Sidcup.
Can you change the grout colour?
Yes. Many clients do. Darker grout can hide marks and lighter grout gives a fresher look.
Landlord and commercial work in Sidcup
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured for the work.
Why it’s worth doing now in Sidcup
Patching a few joints can look like a quick win, but patched grout rarely matches the rest and the old grout carries on failing. Doing the full area gives you one colour and sound joints throughout. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Sidcup, the repair is bigger than the sealant job would have been.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas

Sidcup homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
