Landlord and commercial work in Newnham

About our remedial sealant in Newnham

Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. We work on botched or over-sealed joints, expansion joints and leaking tray & enclosure joints, and the jobs we see most are kitchen joints letting water behind the worktop and products that weren’t meant for the joint.

Being in a small place like Newnham makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.

You get a one-year guarantee, the same in Newnham as everywhere else we work.

How it works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Newnham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at how the sealant has failed and check for movement or a leak path.
  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. We tool the joint and tell you about anything else that needs attention.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work
  • Try not to wet indoor joints just before the visit

Why act early in Newnham

Ripping out a bathroom is not generally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Older cottages and farmhouses around Newnham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Why us?

  • A sealant colour to suit the surroundings
  • You choose the colour before work begins
  • Any old sealant cut out fully, not covered over
  • A choice of colours where the product allows

How to look after the new joints

After the cure time, these simple habits help:

  • Keep movement joints clear of mortar and paint
  • Always have old sealant cut out, not covered
  • Have loose fittings fixed before resealing
  • Look for stains below bathrooms now and then

Keep the room ventilated: use the extractor or open a window after showering.

A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.

What remedial sealant looks like in Newnham

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

For an older house near a landmark such as Church of St Peter and St Paul, older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Teynham station, a joint that keeps failing is best fixed properly while the property is empty.

FAQs for Newnham

Do you work for landlords with property near Teynham station?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is Newnham within the area you cover?

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

Can you fix a reseal that hasn’t worked?

Yes. There’s normally a reason: sealant over sealant, movement or another leak, so we find that first.

Is there any odour?

There can be a smell while the sealant cures. Ventilation helps.

What if the leak is not the sealant?

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.

Do you have insurance?

Yes. We are fully insured.

Where do you work from?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Can failed expansion joints be resealed?

Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Surface by surface

Movement & expansion joints

A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.

Leaking trays & enclosures

If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.

Common problems we fix in Newnham

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, so it tears when the joint moves. Backing sets the depth and stops that.

If you can see any of these, it’s time to have the joints looked at:

  • Sealant that came away because the surface wasn’t prepared
  • Worktop sealant that has shrunk and split
  • Sealant applied over old sealant that has lifted
  • Torn expansion joints

Schools such as Eastling Primary 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.
