How we handle new build mastic in South Alkham

Across South Alkham, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We’re often asked to deal with sealant work across a run of new homes and worktop and upstand sealant coming away, across skirting & floors, kitchens and windows & doors.

Somewhere as small as South Alkham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.

Every job is covered by a one-year guarantee.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Raise failed sealant with the developer while you’re covered
  • Get a leaking seal dealt with right away
  • Use the extractor fan every time you shower
  • Avoid running a DIY bead over the old one

Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

Common problems we fix in South Alkham

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.

These are the problems we are asked about most:

  • Internal frame sealant that has split
  • Untidy sealant flagged on a snagging list
  • Kitchen sealant that has pulled off the wall
  • Sealant applied over dusty or wet surfaces

For new homes near Kearsney station, it’s worth checking the sealant early, while snags are still fresh.

How to choose a mastic man

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

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.

Questions from South Alkham

Is South Alkham in your area for new build mastic?

Yes. We work across London and the South East, and South Alkham is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Will you come out to South Alkham?

Yes, South Alkham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Does someone need to be in?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Do the sealants smell?

That depends on the sealant. Some products have a noticeable smell, others very little.

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

We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.

Do you work through snagging lists?

Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.

Can you reseal over the builder’s sealant?

No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.

Different surfaces, different methods

Windows and doors

A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.

Skirting and floors

Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.

The process

We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. In a small place like South Alkham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Finally, each room is checked and you’re given the cure time.

Before we arrive

  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky
