About our remedial sealant in Crowmarsh Gifford

Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that will not fix it. Typical jobs include sealant applied over old sealant that has lifted and dark patches showing through the sealant, on expansion joints, mouldy bath & shower sealant and failed movement joints.

For a small place like Crowmarsh Gifford, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How we quote for remedial sealant

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

  • The type of sealant required
  • How many areas need sealing
  • When we can work, for business premises
  • Access and height

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we need to know

Before you ask for a quote, have a think about:

  • The type of property
  • Where the job is, and your postcode
  • How many joints, rooms or windows are involved
  • Any previous sealing or DIY work

We do not publish a price list. Instead, we give you a clear quote for your job. To get started, call 0345 464 0079 or send us an email.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

What we do, step by step

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Crowmarsh Gifford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. Once dry, a suitable sealant is applied and tooled.
  5. You get the cure time and our view on why the joint failed.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Let us know about earlier repairs to the joints
  • Clear the area around the work

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Aftercare tips

To keep the joints looking good and working properly:

  • Clean sealant with mild products only
  • Deal with small splits early
  • Never fill a movement joint with mortar or grout
  • Ask why a joint failed before redoing it

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.

Leave it or put it right?

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. Around Crowmarsh Gifford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Why book with us

  • White, clear, grey or another colour, product permitting
  • Sealant colour chosen to suit
  • Every job guaranteed for a year
  • Any old sealant cut out fully, not covered over

What we are called out for in Crowmarsh Gifford

How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

These are the problems we’re asked about most:

  • Dark patches showing through the sealant
  • Sealant that came away because the surface wasn’t prepared
  • A shower that leaks however often it’s resealed
  • Torn expansion joints

For an older house near a landmark such as Church of St Mary Magdalene, older homes can move a little, which is hard on rigid grout and tired sealant.

Your questions about remedial sealant in Crowmarsh Gifford

Is Crowmarsh Gifford in your area for remedial sealant?

Yes. We work across London and the South East, and Crowmarsh Gifford is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.

Will you come out to Crowmarsh Gifford?

Yes. Crowmarsh Gifford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can failed expansion joints be resealed?

Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit.

Are you fully insured?

Yes. We are fully insured.

What if resealing will not fix my leak?

We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we won’t reseal for the sake of it.

Someone resealed my shower and it’s leaking again. Can you help?

Yes, generally. First we check whether the leak is the sealant at all, then strip and reseal the joints.

Is there any odour?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
