How bathroom resealing works in SG7

A bead that has gone black, split or come away is worth sorting before it lets water through. Just call 0345 464 0079 or drop us an email with a photo of the joints, and we will give you a clear quote for bathroom resealing in SG7. Common call-outs are for damp behind the bath or under the tray and lumpy, uneven sealant from a DIY attempt, on basins & vanity units, baths and wet rooms.

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work generally takes two to three hours for a typical bath, depending on how much old sealant there is.

  1. We look at every joint first and check for movement or leaks.
  2. The old silicone is cut out completely, along with the film it leaves on the tiles.
  3. The joint is cleaned, degreased and treated for mould.
  4. With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
  5. We tool the bead to a neat finish and give you the cure time, usually around 24 hours.

Where we work in SG7

SG7 has homes of every age, old and new, and in places like Letchworth Garden City, Baldock and Ashwell there’s plenty of rented property too. Sound sealant and clean grout keep water out and rooms looking cared for.

London and the South East have homes from every era, from period terraces to post-war new towns and new estates. Each needs the right sealant for its age and materials.

Baldock: Homes close to Church of St. Mary the Virgin include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Hartsfield Junior Mixed and Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Signs you need bathroom resealing

Black mould is behind a lot of resealing. Bathrooms without good ventilation keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.

Any of these means the joints need attention:

  • A joint torn by a bath that flexes
  • Lumpy, uneven sealant from a DIY attempt
  • Leaking joints on a shower screen
  • A reseal done over the top of the old bead

Looking after it afterwards

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

  • Clean with a mild bathroom cleaner and a soft cloth
  • Keep bottles off the sealant line
  • Open a window or run the fan so the room dries
  • Dry worktop joints after washing up

Give the silicone time to cure before it gets wet, which is generally around 24 hours. Once it’s cured, wiping it down after use keeps it looking new.

Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What affects the cost of bathroom resealing

Every job gets its own quote. These are the things that affect it:

  • The type of sealant required
  • Whether there’s mould to deal with
  • The number and length of the joints
  • Whether old sealant or filler has to be cut out

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

When you call or email, these details help:

  • If it’s domestic, commercial or a hotel

What happens if it’s left?

Running new silicone over the old joint can look tidy for a few weeks, but it cannot stick to what’s underneath. Water creeps under it and mould follows, and the next reseal means two layers to cut out.

Questions to ask before booking

  • Are they insured?
  • What preparation is included
  • What the quote includes, VAT included or not
  • What happens if they find a problem under the old sealant

FAQs for SG7

Can you get rid of the black mould in my sealant?

Yes. Once mould has grown into the silicone, it usually cannot be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

What colours of sealant can you use?

There’s a choice: clear, white and colours chosen to suit the room. We’ll talk it through when we quote.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How do I get a quote for bathroom resealing in SG7?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Do you reseal kitchen worktops and sinks too?

Yes. Next to the sink we use a food-safe product where it’s needed.
