DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

About our remedial sealant in Milton Keynes

Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with sealant peeling off a dusty or damp surface and gaps opening along the back of the worktop, we can put it right.

Alongside its houses and flats, Milton Keynes has offices, shops and places to stay, all with washrooms and kitchens that need the same care as a family bathroom. Homes and businesses get the same careful preparation before anything new goes in.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Milton Keynes

Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.

People usually contact us when they notice one of these:

  • A shower that leaks however often it’s resealed
  • Sealant that came away because the surface wasn’t prepared
  • Caulk or the wrong sealant used in a wet area
  • Movement joints that have split or pulled away

If you let a flat or house near Milton Keynes Central station, botched sealant from a previous quick fix is easier to strip out between tenants.

Remedial sealant in Milton Keynes: local notes

Milton Keynes is one of the post-war new towns. Many homes date from the post-war decades, so bathrooms and kitchens may be on their second or third set of sealant. Sealant laid over old sealant never bonds properly, so it all has to come out. Milton Keynes has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.

Schools such as Summerfield School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around Church of Christ the Cornerstone, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Why deal with it now?

Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In a busy place like Milton Keynes, a failed joint in a flat or office can send water into the space below, where it can go unnoticed until the damage is done.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Movement from fittings that aren’t supported
  • Tiles that have come away from the wall
  • A tray or bath that is cracked

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

What we seal

  • Botched or over-sealed joints
  • Expansion joints
  • Failed movement joints
  • Leaking tray & enclosure joints
  • Mouldy bath & shower sealant
  • Shrunken worktop sealant

What we do, step by step

On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Where a business in Milton Keynes needs to stay open, out-of-hours working can be arranged, while home visits are arranged within our normal working hours, Monday to Saturday.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. Finally we finish the joint and talk you through what we found.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • Let us know about earlier repairs to the joints

How the job changes by surface

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.

Movement & expansion joints

Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.

FAQs for Milton Keynes

Can you help a landlord with a rental near Milton Keynes Central station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.

Is it worth replacing old sealant in an older home in Milton Keynes?

If it hasn’t been replaced for some years, it’s usually worth it. Sealant does not last for ever, and its life depends on use, cleaning and weather, and many homes in Milton Keynes may already be on their second or third set.

Do you offer different sealant colours?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

What if the leak is not the sealant?

In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.

Can old silicone be taken off without scratching the tiles?

Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.

Can failed expansion joints be resealed?

Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
