Typical jobs include shower seals failing in the first year or two and cracked sealant around new window and door frames, across plot handovers, windows & doors and skirting & floors.

For a new home in or near Peartree Green, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

How the visit works

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots. Parking around Peartree Green is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. Failed or untidy sealant is cut out completely.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Each area is checked and left with its cure time.

Preparing for the visit

  • Keep children and pets away from the work area
  • Let us know if you’ve seen damp or leaks
  • On commercial sites, let us know about site rules

What the job involves on each surface

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.

Skirting and floors

Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.

New homes and floors in Peartree Green

Peartree Green is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In and around Peartree Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Woolston station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Keeping the joints in good condition

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

  • Open a window or run the fan after bathing
  • Keep pictures and emails about snagging items
  • Report sealant problems to your builder during the snagging period
  • Don’t seal over failed sealant yourself

Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

Common questions in Peartree Green

Do you cover smaller places like Peartree Green?

Yes, Peartree Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
