Looking after it afterwards

Aftercare is simple:

  • Let steam out after showers
  • Clean the joints with a mild cleaner
  • Dry the seal after bathing
  • Reseal when black spots won’t clean off

Let it cure fully before using the bath or shower, normally about a day.

Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.

For landlords and businesses

Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover so nothing needs replacing. We’re CHAS, Constructionline and SafeContractor accredited.

We regularly price jobs from inventory or check-out pictures. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.

DIY repairs versus a professional job

If you’re set on a kit, follow its instructions closely, and give it the full curing time. If it fails, we can still put it right.

The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.

Materials and what they mean for the repair

Baths

We fill the bath before sealing, to open the joint fully.

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

Signs you need bath resealing in Baldock

In time, even good sealant discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.

It’s worth getting a quote if you see:

  • Missing sealant behind the taps
  • Black mould in the sealant
  • Silicone smeared on tiles
  • Silicone coming away from the tiles

Before booking anyone

  • Whether the price covers travel
  • How changes to the job are handled
  • What protection goes down before work starts
  • Whether the price is fixed and includes VAT

10 questions to ask before you book

How it works

It’s a tidy, low-fuss visit. We confirm the time with you beforehand, protect the area, then carry out the work, which normally takes a couple of hours. If we find something your pictures didn’t show, we’ll explain it before carrying on.

  1. First we strip out every bit of the old mastic.
  2. Next we clean the joint and deal with mould.
  3. We ensure the joint is completely dry.
  4. For a bath, we fill it with water first so the joint is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, taps included.

Before we arrive

  • Clear the area around the damage
  • Keep pets and children out of the room while we work
  • Let us know which floor the room is on

Getting a price

A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. What comes back is a fixed price, not a guess.

Advice

Why it’s worth resealing in Baldock

Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. A proper reseal removes the old first. We charge the same wherever you are, with no extra for Baldock. What changes the price is the job itself: the material, the amount of damage and how many items.

How we price bath resealing

You will not pay by the hour. The price depends on:

  • The material and finish
  • Any earlier repairs that need removing first
  • The size and number of damaged areas
  • The colour and finish to match

Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Photos let us give you the exact figure.

Getting a price from pictures

We price nearly every job from pictures. This is what to send:

  • A close-up of the damage, in focus
  • A coin beside the damage so we can judge size
  • What it’s made of, if you know
  • The postcode, so we can plan the visit

Pricing is simple: snap the damage close up and then the whole item, send them over with your postcode, and you’ll get a fixed price back. Quotes are free and no obligation.
