New build mastic in Leckford, done properly

Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. We’re often asked to deal with gaps opening as the house dries out and settles and cracked caulk along new skirting, on windows & doors, skirting & floors and kitchens.

Work in a small place like Leckford just needs the journey and access planning, and once on site, the job is the same as anywhere.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Different surfaces, different methods

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 and baths are filled before sealing.

Skirting and floors

Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.

Common problems we fix in Leckford

The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.

Signs it’s time to call us include:

  • Sealant applied over dusty or wet surfaces
  • Cracked caulk along new skirting
  • Leaking shower tray seals in a new home
  • Smeared, uneven beads picked up at snagging

For jobs in and around Leckford, choosing the right material for each joint is as important as a tidy finish.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Act quickly if a seal starts to leak
  • Resist patching a failed seal with a tube from the DIY shop
  • Keep water off fresh sealant until it has cured
  • Keep photos and emails about snagging items

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

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Leckford: your questions answered

Do you cover smaller places like Leckford?

Yes, Leckford 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.

Do you do commercial work?

Yes, regularly. Larger jobs can be planned room by room or area by area.

Why has my new-build shower seal failed already?

New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

What affects the quote in Leckford

We do not publish a price list, because jobs vary so much. The quote depends on:

  • The number of rooms or windows
  • Mould in or behind the old joints
  • When we can work, for business premises
  • How easy the joints are to reach

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • The address or postcode of the job
  • Whether it has been sealed before

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear quote.

What happens on the day

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases.
