How to look after the new joints

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

  • Don’t wait for the house to settle if water is getting through
  • Avoid scourers and strong chemicals on sealant
  • Keep water off fresh sealant until it has cured
  • Watch for new gaps as the house dries out

Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.

Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

New build mastic for homes and businesses in Hoe Gate

New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Common call-outs are for smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, across bathrooms & en suites, show homes and windows & doors.

For a small place like Hoe Gate, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

There’s a 12-month guarantee on every job, large or small.

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What the job involves on each surface

Bathrooms and en suites

Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.

Skirting and floors

As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Hoe Gate: your questions answered

Will you come out to Hoe Gate?

Yes, Hoe Gate is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Portchester station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Should I try DIY first?

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.

Are you fully insured?

Yes. We’re fully insured.

Can you match the sealant colour to my new kitchen or bathroom?

Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.

Why does sealant fail so quickly in new builds?

There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

What we can’t put right

Before booking, it’s worth knowing the limits:

  • Your warranty claim itself, which is between you and the builder
  • Cracked trays, tiles or worktops
  • Movement caused by a poorly fitted tray or bath

If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Why act early in Hoe Gate

The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Hoe Gate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

Why book with us

  • Anti-fungal sanitary silicone in wet areas
  • Trusted Arbo and Everbuild sealants
  • Sealant colour chosen to suit
  • Homes, businesses and hotels

How the visit works

When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Hoe Gate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
